1. Field of the Invention
The present invention relates to a method for regenerating catalyst employed in a fluid catalytic cracking process wherein a hydrocarbon is cracked catalytically in a reaction zone under cracking conditions with the concomitant deposition of non-volatile carbonaceous deposits, or coke, upon the catalyst. More specifically, the present invention is directed to a regeneration process wherein a regeneration flue gas is obtained which contains a reduced concentration of carbon monoxide and wherein a regenerated catalyst is obtained having a reduced residual carbon content. These results are achieved by regulating the amount of coke deposited on the catalyst in the reaction zone and by adjusting the catalyst circulation rate.
2. Description of the Prior Art
The fluidized catalytic cracking of hydrocarbons is well known in the prior art and may be accomplished in a variety of processes which employ fluidized solid techniques. Normally in such processes, suitably preheated, relatively high molecular weight hydrocarbon liquids and/or vapors are contacted with hot, finely-divided, solid catalyst particles either in a fluidized bed reaction zone or in an elongated riser reaction zone, and maintained at an elevated temperature in a fluidized state for a period of time sufficient to effect the desired degree of cracking to lower molecular weight hydrocarbons typical of those present in motor gasolines and distillate fuels.
During the cracking reaction, coke is deposited on the catalyst particles in the reaction zone thereby reducing the activity of the catalyst for cracking and the selectivity of the catalyst for producing gasoline blending stock. In order to restore a major proportion of activity to the coke contaminated or spent catalyst, the catalyst is transferred from the reaction zone into a regeneration zone wherein the catalyst is contacted with an oxygen-containing regeneration gas, such as air, under conditions sufficient to burn at least a portion, preferably a substantial portion, of the coke from the catalyst. The regenerated catalyst is subsequently withdrawn from the regeneration zone and reintroduced into the reaction zone for reaction with additional hydrocarbon feed. Commonly, spent catalyst from the reaction zone is passed therefrom to a stripping zone for removal of strippable hydrocarbons from the catalyst particles prior to transferring the catalyst to the regeneration zone.
Typical regeneration zones in the prior art comprise large vertical cylindrical vessels wherein the spent catalyst is maintained as a fluidized bed by the upward passage of an oxygen-containing regeneration gas. The fluidized catalyst forms a dense phase catalyst bed in the lower portion of the vessel and a dilute catalyst phase containing entrained catalyst particles above, with an interface existing between the two phases. Flue gas, which normally comprises gases arising from the combustion of the coke on the spent catalyst, inert gases such as nitrogen from air, any unconverted oxygen and entrained catalyst particles, is then passed from the dilute catalyst phase into solid-gas separation means within the regeneration zone to prevent excessive losses of the entrained catalyst particles. The catalyst particles separated from the flue gas returned to the dense phase catalyst bed. A substantially catalyst-free flue gas may then be passed from the separation means to equipment downstream thereof, for example to a plenum chamber, or be discharged directly from the top of the regeneration zone. Cyclone separators are commonly used as separation means.
Catalysts commonly employed in the catalytic cracking process, for example amorphous silica-alumina, silica-alumina zeolitic molecular sieves, silica-alumina zeolitic molecular sieves ion exchanged with divalent metal ions, rare earth metals, etc., and mixtures thereof, are adversely affected by exposure to excessively high temperatures. More specifically, at excessively high temperatures, the structure of such catalytic-cracking catalysts undergoes physical change, usually observable as a reduction in the surface area for those catalysts which do not contain zeolitic components. This loss of surface area results in a substantial decrease in catalytic activity. In the case of zeolitic catalysts, this physical change may be manifested as the loss of crystallinity with little change in surface area. However, the physical change does cause a large loss of activity which can be demonstrated in analytical catalyst test procedures. Consequently, it is preferable to maintain the catalyst employed in a fluidized catalytic cracking process at temperatures below which substantial physical change of the active catalyst sites occurs. It has been found that silica-alumina cracking catalysts such as those described above containing crystalline zeolites may be subjected to temperatures of up to 1500° F. without substantial damage to the physical structure of the catalyst. Thus according to the present invention, regeneration process variables may be adjusted to properly achieve the desired low residual carbon upon regenerated catalyst within the above temperature limitation.
The burning of coke deposits from the catalyst in the regeneration zone may be characterized in a simplified manner as the oxidation of carbon and represented by the following chemical equations:
C + O2 → CO2 ( 1)
2C + O2 → 2CO (2)
2CO + O2 → 2CO2 ( 3)
Reactions (1) and (2) both occur under typical catalyst regeneration conditions wherein the catalyst temperatures may range from about 1050° to about 1300° F. and are exemplary of gas-solid chemical interactions when regenerating catalyst at temperatures within this range. The effect of any increase in temperature is reflected in an increased rate of combustion of carbon and a more complete removal of coke from the catalyst particles. Gas phase reaction (3) is also accelerated by increased temperature as well as higher pressure and, particularly, the amount of oxygen present. Somewhat lower temperatures may be employed where an added carbon monoxide combustion catalyst or promoter is employed. The promoter may be incorporated into the catalyst or introduced into the regeneration zone separately. In addition to the above reactions which relate to the formation of carbon monoxide and carbon dioxide from carbon, water is formed from hydrogen in the coke.
It has been observed that reduced amounts of residual carbon upon a regenerated catalyst, particularly silica-alumina catalysts containing a crystalline alumino-silicate component which are often referred to as molecular sieve catalysts, results in both improved catalyst activity and catalyst selectivity for the conversion of hydrocarbons to the desired product or products. In the regeneration of catalytic cracking catalysts, particularly high activity molecular sieve type cracking catalysts, it is desirable to burn a substantial portion of the coke from the catalyst such that the residual carbon upon regenerated catalyst is very low, preferably less than about 0.1 wt. %. One difficulty which arises in regenerating catalyst to a low residual carbon level is that as the coke is burned with oxygen, it tends to produce substantial amounts of carbon monoxide which is subject to further oxidation into carbon dioxide as represented by reaction (3) above, a highly exothermic reaction. The use of an amount of oxygen theoretically sufficient to burn coke in the fluidized catalyst bed to a desired low level of residual coke upon regenerated catalyst has had the frequent undesirable effect of evolving a combustible mixture of oxygen and carbon monoxide in the dilute catalyst phase which may undergo the further combustion commonly referred to as "afterburning". (See "Oil and Gas Journal", Vol. 53 (No. 3), pp. 93-94, 1955 for further discussion.) The "afterburning" causes a substantial increase in the temperature of the dilute catalyst phase which may exceed about 1500° F. Such high temperatures in the dilute catalyst phase can cause deactivation of the catalyst, thereby requiring additional catalyst replacement to the process in order to maintain a desired catalytic activity in the hydrocarbon reaction zone. Additionally, these high temperatures may cause damage to mechanical components of the regeneration zone, particularly in that portion of the regeneration zone in contact with the substantially catalyst-free flue gas wherein the temperature may increase to 1800° F. or greater. Such excessive temperatures in the substantially catalyst-free flue gas occur when reaction (3) does not proceed at a sufficient rate in the dense bed phase and in the dilute catalyst phase such that said flue gas contains an excess of oxygen and carbon monoxide so as to cause afterburning to be initiated Reaction (3) then proceeds rapidly within the substantially catalyst-free flue gas since there is very little entrained catalyst present to absorb the heat released, and thereby reduce the rise in temperature. Thus, in that portion of the regeneration zone wherein the flue gas is substantially catalyst-free, there will occur a rapidly accelerating rise in temperature due to the heat released as complete combustion of carbon monoxide occurs or as the available oxygen is utilized, in the absence of any means to moderate the temperature therein.
Several methods have been proposed to overcome undesirable afterburning in that portion of the regeneration zone containing the substantially catalyst-free flue gas. One method used in industry is to control the oxygen-containing gas stream entering the regeneration zone directly responsive to a predetermined temperature differential between the outlet of the dilute catalyst phase and the dense bed of the regeneration zone in order to minimize excess oxygen therein. This practice eliminates excessive temperatures in that portion of the regeneration zone in contact with the substantially catalyst-free flue gas and produces a small amount of oxygen in said flue gas, generally less than about 0.5 vol. %. However, this procedure has limited effect in attaining low levels of residual carbon on regenerated catalyst at conventional fluid catalytic cracker operating conditions wherein the dense phase bed temperature ranges from about 1050° to about 1250° F. and the amount of uncombusted carbon monoxide ranges from about 6 - 12 vol. %. (See for example U.S. Pat. No. 3,206,393.)
When catalyst regeneration is carried out to obtain a regenerated catalyst with low residual carbon content and a low carbon monoxide level in the flue gas, there have been, in general, three approaches suggested to overcome excessively high temperatures in the dilute catalyst phase. In one approach, a cooling medium which may comprise steam, liquid water, unregenerated catalyst, hydrocarbon oil, flue gas, etc. is injected to cool the dilute catalyst phase below a temperature which will cause damage to the catalyst or to mechanical members of the regeneration zone (see for example U.S. Pat. Nos. 2,393,839, 2,454,373 and 2,580,827). Another approach is to employ series catalyst regeneration wherein the catalyst to be regenerated is contacted in a plurality of dense phase regeneration zones with an oxygen-containing regeneration gas in which the catalyst flows from zone to zone, the temperature in each zone not exceeding a temperature at which excessive afterburning will occur. (See for example U.S. Pat. Nos. 2,788,311, 3,494,858, and 3,563,911). The third approach involves the use of indirect heat exchange, such as steam generation coils in the dense phase bed. When such methods are employed in conventional fluid catalytic cracker operations, the amount of carbon monoxide present in the flue gas may still be substantial, generally being in the range of from 6 - 12 vol. %. In addition, the above methods result in the loss of recoverable heat from the process or require expenditures for the use of additional equipment.
More recently, several published foreign patent applications making claim to priority applications filed in the United States have suggested reducing the levels of both residual carbon on regenerated catalyst and emissions of carbon monoxide by operating the dense phase bed in the regeneration zone at elevated temperatures, that is, temperatures ranging from about 1250° to about 1400° F. These high dense phase bed temperatures can result in substantial afterburning in the dilute catalyst phase and may be prevented by techniques similar to and having the same disadvantages as those mentioned above. As an example, published Netherlands application 72,15798 discloses a two-stage process for regenerating fluid catalytic cracking catalysts at elevated temperatures, thereby favoring substantially complete combustion of carbon monoxide, with a provision for recovering the heat evolved in the dilute catalyst phase by the use of a circulating stream of partially regenerated catalyst.
As another example, U.S. Pat. No. 3,844,973 and Netherlands application 73,07445 disclose a regeneration zone which comprises a first dense bed, a dilute phase transport riser, and a second dense bed. The carbonaceous deposits are oxidized in the first dense bed to produce a partially spent regeneration gas containing carbon monoxide and a regenerated catalyst. The regeneration gas and regenerated catalyst are then passed to a dilute phase transport riser wherein, preferably, carbon monoxide is combusted to carbon dioxide, with the regenerated catalyst being passed to the second dense bed from which it is returned to the reaction zone. Thus the oxidation of both carbon monoxide and coke occur within the same regeneration zone but, preferably, at different locations. The application also discloses control of the temperature of the regenerated catalyst returning to the reaction zone independently of the coke oxidation and as another variation, control of the coke on spent catalyst to a predetermined residual level by adjusting the regeneration gas rate to the first dense bed.
Other published foreign patent applications based on U.S. applications relate to controlling the oxidation of carbon monoxide to carbon dioxide in the dense bed phase by regulating the oxygen rates passing into the regeneration zone in order to reduce the level of coke on regenerated catalyst leaving the regeneration zone and to minimize, if not totally eliminate, afterburning occuring within the regeneration zone. (See for example German application 2,327,209 and Netherlands application 73,09759.) However, for a commercially operating fluid catalytic cracking unit, any appreciable increase in regeneration gas rate might require additional blower or compressor capacity, thereby necessitating an added expenditure. In addition, although the low residual carbon on regenerated catalyst and the low carbon monoxide level in the flue gas can be maintained by adjusting the regeneration gas rate and hence the oxygen concentration in the regeneration zone, this method has the disadvantage of involving the interaction of several process variables. For example, changes in the regeneration gas rate, while maintaining the excess oxygen in the regeneration zone at a constant level, will result in a directly proportional heat release in said zone. The differential heat evolved will cause a change in the dense phase bed temperature which in turn must be compensated for by adjusting the catalyst circulation rate. This changes the temperature in the reaction zone which in turn causes a variation in the coke make which requires complicated secondary corrective measures.
Thus, in view of the disadvantages of the foregoing prior art, it would appear desirable to have a method of reducing the residual carbon on regenerated catalyst and the carbon monoxide content in the flue gas to desirable low levels in the absence of excessive afterburning in that portion of the regeneration zone occupied by substantially catalyst-free flue gas. It would also be desirable to be able to practice such a method in said portion of the regeneration zone of a conventional fluid catalytic cracking unit wherein the carbon monoxide and oxygen content of the flue gas ranges from about 6 - 12 vol. % and 0.1 - 0.8 vol. %, respectively, without the need to regulate the regeneration gas rate, employ extraneous cooling means, or use a multi-stage regeneration zone to reduce the temperature therein and thus inhibit afterburning.
Now according to the present invention, these and other disadvantages of the prior art have been overcome by providing a method for regenerating a coke contaminated cracking catalyst at a substantially constant regeneration gas rate, thereby enabling the carbon level on regenerated catalyst to be maintained at an extremely low level while providing a flue gas having a very low carbon monoxide content in the absence of excessive afterburning in that portion of the regeneration zone wherein the flue gas is substantially catalyst-free.
The process of the present invention comprises contacting a dense phase fluidized bed of coke contaminated catalyst in a regeneration zone according to the steps of:
1. burning at least a portion of coke from the coke-contaminated catalyst to effect the partial conversion of said coke to carbon monoxide and carbon dioxide;
2. reducing the coke make in the reaction zone for a time sufficient to effect an increased oxygen concentration in the regeneration zone to burn at least an additional portion of coke from the coke-contaminated catalyst prior to obtaining a substantially catalyst-free flue gas and substantially complete the conversion of the carbon monoxide from said burning to carbon dioxide; and
3. maintaining substantially complete conversion of coke to carbon dioxide in the regeneration zone at a temperature below that used in step (1), steps (1), (2) and (3) being effected without excessive afterburning in that portion of the regeneration zone wherein the flue gas is substantially catalyst-free.
According to the method of the present invention, an excess of oxygen relative to the coke to be burned is employed in steps (2) and (3), such that at least 0.4 and preferably at least 0.8 vol. % of free oxygen is present in the substantially catalyst-free flue gas. The amount of free oxygen present is controlled by adjusting the coke make in the reaction zone. The variation of excess oxygen in the substantially catalyst-free flue gas permits control of the temperature therein, thereby avoiding variation of the oxygen-containing regeneration gas rate and the use of additional cooling means to overcome excessive temperatures due to afterburning.
An outstanding advantage of the present invention is in providing a procedure for obtaining low levels of residual carbon on regenerated catalyst and carbon monoxide, content in the flue gas from a conventional fluid catalytic cracking operation in the absence of excessive afterburning in that portion of the regeneration zone wherein the flue gas is substantially catalyst-free. More particularly, by following the method of the present invention, temperatures in the dilute catalyst phase are controlled within a range below the temperatures at which the catalyst suffers substantial loss of activity. Similarly, temperatures in that portion of the regeneration zone in contact with the substantially catalyst-free flue gas may be maintained within a range below which the mechanical components of the regeneration zone are damaged or lose strength.
Yet another outstanding advantage of this invention lies in providing a regenerated catalyst having extremely low residual carbon thereon, preferably less than 0.1 wt. %, and generally possessing enhanced activity and selectivity characteristics more closely associated with those of fresh cracking catalyst. Accordingly, higher conversions of feedstock and higher yields of desirable conversion products may be achieved. Also by following the method of the present invention, such catalyst regeneration may be accomplished without the need of additional cooling means in that portion of the regeneration zone in contact with the substantially catalyst-free flue gas. In addition, the carbon monoxide content of the substantially catalyst-free flue gas can be maintained at less than about 0.1 vol. %, preferably less than about 0.05 vol. %. This low level of carbon monoxide in the flue gas permits the direct release of effluent gases to the atmosphere while meeting present ambient air quality standards. This added advantage permits the elimination of capital expenditures otherwise required for installation of boilers for the combustion of carbon monoxide. The present invention has the additional advantage of allowing the catalyst to be regenerated in a single dense phase bed, although it may be applied to a regeneration zone having multiple beds. Further the method claimed herein may be employed during the start-up period or during normal operations.
The single FIGURE is a diagramatic representation of one form of apparatus adapted for practicing the present invention and includes a reaction zone and a regeneration zone suitable for use in the catalytic cracking of hydrocarbons.
Having thus described the invention in general terms, reference is now made to the single schematic drawing. It is to be understood that the drawing is shown only for the purpose of illustrating a typical fluid catalytic cracker configuration. Such details are included as are necessary for a clear understanding of how the present invention may be applied to said system. No intention is made to unduly limit the scope of the present invention to the particular configuration shown as other configurations are contemplated. Various items such as valves, pumps, compressors, steam lines, instrumentation and other process equipment and control means have been omitted therefrom for the sake of simplicity. Variations obvious to those having ordinary skill in the art of catalyst regeneration processes are included within the broad scope of the present invention.
Referring now to the drawing, the system illustrated includes a vertically arranged cylindrical reaction zone 10 containing a fluidized bed 11 of catalyst having a level indicated at 12, in which the hydrocarbon feedstock introduced at line 13 is undergoing catalytic cracking. Hydrocarbon gas and vapors passing upward through fluid bed 11 maintain the bed in a dense turbulent fluidized condition having the appearance of a boiling liquid. A separate regeneration zone 14 arranged at approximately the same level as reaction zone 10 contains a dense phase catalyst bed 15 having a level indicated at 16, which is undergoing regeneration to burn off coke deposits formed in the reaction zone during the cracking reaction. An oxygen-containing regeneration gas enters the regeneration zone 14 by line 17 and passes upward through the dense phase catalyst bed 15, maintaining it in a turbulent fluidized condition similar to that present in the reaction zone 10.
Spent catalyst to be regenerated is withdrawn from reaction zone 10 and flows downward through stripping zone 18. A line 19 supplies stripping steam or other stripping gas into the bottom of the stripping zone. Catalyst withdrawn from the bottom of stripping zone 18 passes through U-bend 20 into the connecting vertical riser 21 which extends into the lower portion of the regeneration zone 14 and terminates within the dense phase catalyst bed 15. Air is added via line 22 in a quantity sufficient to reduce the density of the catalyst flowing in riser 21, thus causing the catalyst to flow upward into the regeneration zone 14 by simple hydraulic balance.
Regenerated catalyst from the dense phase catalyst bed 15 in the regeneration zone 14 flows downward through standpipe 23 and passes through U-bend 24 into the reaction zone 10 by way of the transfer line 25, which joins U-bend 24 at the level of the oil injection line 13 above the U-bend. The hydrocarbon feedstock for the cracking process is injected into line 25 through line 13 to form an oil and catalyst mixture which is passed into the fluid bed 11 within the reaction zone 10. Product vapors containing entrained catalyst particles pass overhead from fluid bed 11 into a gas-solid separating means 26 wherein the entrained catalyst particles are separated therefrom and returned through diplegs 27 leading back into fluid bed 11. The product vapors are then conveyed through line 28 into the product recovery system.
In regeneration zone 14, flue gases formed during regeneration of the spent catalyst pass from the dense phase catalyst bed 15 into the dilute catalyst phase 29 along with entrained catalyst particles. The catalyst particles are separated from the flue gas by a suitable gas-solid separation means 30 and returned to the dense phase catalyst bed 15 via diplegs 31. The substantially catalyst-free flue gas then passes into a plenum chamber 32 prior to discharge from the regeneration zone 14 through line 33.
The amount of residual carbon on regenerated catalyst has a significant influence on the conversion and product distribution obtained in the fluidized catalytic cracking of hydrocarbon feedstocks, particularly wherein high activity molecular sieve type cracking catalysts are employed. For example, at constant operating conditions and constant coke production, a decrease in the weight % carbon on regenerated sieve catalyst of from 0.35 to about 0.1 will give an increase in conversion of hydrocarbons, e.g. by as much as about 2.5 vol. %, the increase in conversion being accompanied by a decreased production of less valuable heavy fuel oil. Similarly it could be projected that a decrease in carbon on regenerated sieve catalyst from about 0.2 to about 0.05 wt. % may improve conversion by about 2 vol. % or more and improve gasoline yield by about 1.4 vol. %.
By using the method of the present invention, coke contaminated catalysts may be regenerated to a low residual carbon content, 0.1 wt. % or less, in a single dense phase regeneration zone at temperatures below about 1500° F. at a substantially constant regeneration gas rate. This may be accomplished by first increasing the temperature of the dense phase fluidized catalyst bed to a level sufficient to burn at least a portion of the coke from the coke contaminated catalyst in order to partially convert the coke to carbon monoxide and carbon dioxide without excessive afterburning in that portion of the regeneration zone wherein the flue gas is substantially catalyst-free. Typically the temperature to which the dense phase bed is raised will range from about 1250° to about 1400° F. Raising the temperature of the dense phase bed causes an increase in the coke burning reactions (1) and (2), thereby establishing a lower equilibrium concentration of residual carbon on regenerated catalyst. The composition of the flue gas remains substantially constant during this step because the amount of coke being produced in the reaction zone is maintained substantially constant. If not, sufficient extraneous fuel such as torch oil may be added to the regeneration zone so as to maintain the composition of the flue gas substantially constant.
Once the elevated temperature operation has been established, the coke make in the reaction zone is reduced for a time sufficient to effect an increased oxygen concentration in the regeneration zone, thereby causing an additional portion of coke from the coke contaminated catalyst to be burned in the regeneration zone prior to obtaining a substantially catalyst-free flue gas and completing the conversion of carbon monoxide to carbon dioxide. The reduction of coke make in the reaction zone has the effect of providing an excess of oxygen-containing gas in the regeneration zone relative to the amount of coke on the coke-contaminated catalyst without increasing the regeneration gas rate. The presence of the excess oxygen allows the combustion of carbon monoxide to carbon dioxide to occur in the dense phase catalyst bed and the dilute catalyst phase wherein sufficient catalyst is present to absorb the heat released without the use of extraneous cooling means. Thus the carbon monoxide content in the substantially catalyst-free flue gas will be reduced because the carbon monoxide will be combusted to carbon dioxide prior to reaching that portion of the regeneration wherein the flue gas is substantially catalyst-free. Hence, there will be insufficient free oxygen reaching that portion of the regeneration zone wherein the flue gas is substantially catalyst-free to cause excessive afterburning therein.
Following the establishment of a low residual carbon level on regenerated catalyst and a low carbon monoxide content in the substantially catalyst-free flue gas at an elevated temperature, the temperature of the dense phase catalyst bed is reduced to a level sufficient to maintain the substantially complete conversion of coke to carbon dioxide without excessive afterburning in that portion of the regeneration zone wherein the flue gas is substantially catalyst-free. The temperature reduction of the dense phase bed will range from about 20° to about 100° F., preferably from about 40° to about 80° F., below the elevated temperature established in the first and second steps above. The reduced bed temperature favors a lower deactivation rate of the regenerated catalyst than that obtained at the higher temperatures.
The combustion of carbon monoxide to carbon dioxide will continue in the dense phase bed and dilute catalyst phase as the temperature is reduced, thereby maintaining a desirable low level of carbon monoxide in that portion of the regeneration zone wherein the flue gas is substantially catalyst-free. Any afterburning in the substantially catalyst-free flue gas will be minimal due to the low carbon monoxide content therein. While reducing the temperature of the dense phase bed, it may also be necessary to reduce the coke make in the reaction zone to a level sufficient to insure the substantially complete conversion of coke to carbon dioxide. This has the effect of continuing to maintain an excess of oxygen in that portion of the regeneration zone wherein the flue gas is substantially catalyst-free.
The coke make in the reaction zone may be controlled in any suitable manner such as by adjusting the temperature in the reaction zone or by varying the catalyst holdup in the reaction zone. Similarly, the temperature of the dense phase catalyst bed may be controlled in any convenient manner, for example, by decreasing the catalyst circulation rate to increase said dense bed temperature. Several alternate methods may also be used to raise the temperature of the dense phase bed. They include introducing torch oil into the dense bed of the regeneration zone where it is oxidized, increasing the feed preheat temperature while maintaining the temperature in the reaction zone substantially constant, preheating the regeneration gas, and using a feedstock in the reaction zone having a relatively high Conradson carbon content. Methods of controlling the coke make in the reaction zone and increasing the temperature of the dense phase bed in the regeneration zone, additional to those enumerated above, are contemplated and would be obvious to one skilled in the art.
Oxygen-containing regeneration gases which may be employed in the process of the present invention are those gases which contain molecular oxygen in admixture with a substantial portion of an inert diluent gas. Air is a particularly suitable regeneration gas. An additional gas which may be employed is air enriched with oxygen. Additionally, if desirable, steam may be added to the dense phase bed along with the regeneration gas or separately therefrom to provide additional inert diluents and/or fluidization gas. In order to obtain an adequately fluidized dense phase catalyst bed which has good heat transfer throughout the bed and which does not contain relatively dead spots wherein localized temperatures may exceed temperatures which cause damage to the catalyst, the specific vapor velocity of the regeneration gas may suitably be in the range of from about 0.8 to about 6.0 feet/sec, preferably from about 1.5 to about 4 feet/sec.
Suitable petroleum fractions for use in the present invention include naphthas, light gas oils, heavy gas oils, wide-cut gas oils, vacuum gas oils, kerosenes, decanted oils, residual fractions, reduced crude oils, cycle oils derived from any of these, as well as suitable fractions derived from shale oil kerogen, tar sands bitumen processing, synthetic oils, coal hydrogenation, and the like. Such fractions may be employed singly, separately in parallel reaction zones, or in any desired combination.
In general, any commercial catalytic cracking catalyst designed for high thermal stability would be suitable. Suitable catalysts for regeneration include those containing silica and/or alumina. Other refractory metal oxides such as magnesia or zirconia may be employed and are limited only by their ability to be effectively regenerated under the selected conditions. With particular regard to catalytic cracking, preferred catalysts include the combinations of silica and alumina, containing 10 to 50 wt. % alumina, and particularly their admixtures with molecular sieves or crystalline aluminosilicates. Admixtures of clay-extended aluminas may also be employed. Such catalysts may be prepared in any suitable method such as by impregnation, milling, co-gelling, and the like, subject only to provision of the finished catalyst in a physical form capable of fluidization.
Suitable molecular sieves include both naturally occurring and synthetic aluminosilicate materials, such as faujasite, chabizite, X-type and Y-type aluminosilicate materials and ultra stable, large pore crystalline aluminosilicate materials. The fundamental structure of the molecular sieves comprises silicon and aluminum atoms that are tetrahedrally coordinated with four oxygen atoms. The valence charges (+3) of the aluminum atom are not balanced by the four coordinated oxygen atoms so that there is a net negative charge of the alumina tetrahedra. These charges are balanced by cations, generally sodium or potassium, interspersed within the structure. All or a portion of the cations can be replaced with hydrogen ions, aluminum ions or metal cations, rare earth, manganese, cobalt, zinc and other metals of Groups I through VIII of the Periodic Table. When admixed with for example, silica-alumina to provide a petroleum cracking catalyst, the molecular sieve content of the fresh finish catalyst particles is suitably within the range from 5-15 wt. %, preferably 8-10 wt. %. An equilibrium molecular seive cracking catalyst may contain as little as about 1 wt. % crystalline material.
The terms "spent catalyst" or "coke contaminated catalyst" as used herein generally refer to catalyst which has passed through a reaction zone and which contains a sufficient quantity of coke thereon to cause activity loss, thereby requiring regeneration. Generally, the coke content of spent catalyst can vary anywhere from about 0.5 to about 5 wt. % or more. Typically, spent catalyst coke contents vary from about 0.5 to about 1.5 wt. %.
The spent catalyst from the reaction zone is usually passed to a stripping zone for removal of strippable hydrocarbon therefrom prior to discharge into the regeneration zone. The stripping zone is suitably maintained essentially at the reaction zone temperature which ranges from 850° to 1100° F. A preferred stripping gas is steam, although nitrogen, other inert gas or flue gas may be employed. The stripping gas is usually introduced at a pressure in the range of from 10 to 50 psig and effects substantially complete removal of volatile components from the spent conversion catalyst. Stripped spent catalyst particles enter the dense bed of the regeneration zone through suitable lines from the stripping zone. Entry may be from the top, bottom or from the side of the dense bed. Alternatively, the spent catalyst may be mixed with the regeneration gas after exiting from the reaction zone, said mixture being introduced to the bottom of the regeneration zone.
The term "coke make" as used herein refers to the coke content of deposits that leave the reaction zone on the spent catalyst. These deposits may be graphitic in nature or hydrocarbon components of low hydrogen content. The hydrocarbon components comprise heavy molecular weight components of the feedstock, condensation products from the cracking reaction or unstripped light materials which were not removed completely in the stripping zone.
As in the prior art, the regeneration zone employed in the present invention normally comprises vertical cylindrical vessels wherein the catalyst to be regenerated is maintained as fluidized bed by the upward passage of an oxygen-containing regeneration gas thereby forming a dense phase catalyst bed and a dilute catalyst phase with an interface in between. The dense phase bed, which is usually located in the lower portion of the regeneration zone, is maintained at a temperature in the range of from about 1150°-1400° F., preferably from about 1250°-1400° F., and has a density ranging from about 8 to about 30 lb./cubic foot. The density of the dense phase bed may range from about 8 to about 30 lb/cu. ft.
The dilute catalyst phase is the primarily gaseous phase volume located above the dense phase bed within the regeneration zone. Specifically, the dilute phase contains relatively small quantities of catalyst compared to the dense phase bed. For example, the density of the dilute phase bed ranges from about 0.1 to about 1.0 lb./cu.ft. at the inlet to the separation means and from about 1 to about 5 lb./cu.ft. near the interface between the dense bed phase and the dilute catalyst phase. In many instances, the overall flow in the dilute phase is a concurrent flow of catalyst entrained with flue gases. It is contemplated that the dilute catalyst phase can include substantial quantities of the dense bed material which passes into that phase from excessive agitation or bubbling of gaseous materials through the dense bed. In general, the temperature in the dilute catalyst phase is at least that in the dense bed phase and is advantageously maintained within the range from about 1250° to about 1450° F., preferably from about 1260° to about 1420° F., more preferably from about 1270° to about 1400° F., and most preferably from about 1270° to about 1370° F.
The term "substantially catalyst-free flue gas" is the gaseous phase volume located within or downstream of the catalyst separation means within the regeneration zone. Specifically, the "substantially catalyst-free flue gas" comprises flue gas from the dilute catalyst phase from which entrained catalyst particles have been substantially removed. This corresponds to the gaseous effluent from the separation means within the regeneration zone wherein the concentration of entrained catalyst particles will be less than about 50 preferably less than about 30 grains per actual cubic foot. The term "actual cubic foot" refers to the volume measured at actual operating conditions without correction to a standard temperature and pressure. The substantially catalyst-free flue gas from the separation means may be discharged to a variety of downstream equipment such as a dispersion means to redistribute the flue gas, stack valves, a plenum chamber and the like, prior to leaving the regeneration zone. By the use of the method of the present invention, substantial afterburning, and hence excessive temperatures in that portion of the regeneration zone wherein the flue gas is substantially catalyst-free, may be avoided. The temperature in that portion of said regeneration zone is maintained at least equal to that of the dilute catalyst phase at the inlet to the separation devices but no more than 50° F., preferably no more than 30° F. and most preferably no more than 20° F. above that at said inlet. Although not necessary to the practice of the present invention, extraneous cooling means such as steam may be employed to further reduce the temperature and thereby inhibit the afterburning reaction in that portion of the regeneration zone wherein the flue gas is substantially catalyst-free.
One or more gas-solids separation means may be utilized in the dilute catalyst phase to separate entrained regenerated catalyst particles from the regeneration gas. Preferred separation means will be cyclone separators, multiclones or the like whose design and construction are well known in the art. In the case of cyclone separators, a single cyclone may be used, but preferably, more than one cyclone will be used in parallel or in series flow to effect the desired degree of separation.
The construction of the regeneration zone can be made with any material sufficiently able to withstand the relatively high temperatures involved when afterburning is encountered within the vessel and the high attrition conditions which are inherent in systems wherein fluidized catalyst is regenerated and transported. Specifically, metals are contemplated which may or may not be lined. More specifically, ceramic liners are contemplated within any and all portions of the regeneration zone together with alloy use and structural designs in order to withstand temperatures of about 1400° F. and, for reasonably short periods of time, temperatures which may be as high as 1800° F.
The pressure in the regeneration zone is usually maintained in a range from about atmospheric to about 50 psig., preferably from about 10 to 50 psig. It is preferred, however, to design the regeneration zone to withstand pressures of up to about 100 psig. Operation of the regeneration zone at increased pressure has the effect of promoting the conversion of carbon monoxide to carbon dioxide and reducing the temperature level within the dense bed phase at which the substantially complete combustion of carbon monoxide can be accomplished. The higher pressure also lowers the equilibrium level of carbon on regenerated catalyst at a given regeneration temperature.
The residence time of the spent catalyst in the regeneration zone is not critical. In general, it can vary from about 1 to about 6 minutes. Typically it can vary from about 2 to about 4 minutes. The contact time or residence time of the flue gas in the dilute catalyst phase establishes the extent to which the combustion reaction can reach equilibrium. The residence time of the flue gas may vary from about 10 to about 60 seconds in the regeneration zone and from about 2 to about 15 seconds in the dense bed phase. Preferably, the residence time of the flue gas varies from about 15 to about 20 seconds in the regeneration zone and from about 6 to about 10 seconds in the dense bed.
A benefit derived from this regeneration process is that the regenerated catalyst leaving the regeneration zone has a very low residual carbon content, for example less than 0.2 wt. % and preferably less than 0.1 wt. %. As used in this specification, regenerated catalyst is catalyst leaving the regeneration zone which has contacted an oxygen-containing gas causing at least a portion, preferably substantially all, of the coke present on the catalyst to be removed. More specifically, the carbon content of the regenerated catalyst can vary anywhere from about 0.01 to about 0.2 wt. %, preferably 0.01 to about 0.1 wt. %, and more preferably from about 0.01 to about 0.05 wt. %, and most preferably from about 0.01 to about 0.03 wt. %.
Another benefit from this novel regeneration process relates to the unusually low carbon monoxide content of the effluent gas stream from the regeneration zone. Whereas flue gas from a conventional regeneration of cracking catalyst usually contains from about 6-12% carbon monoxide, a similar amount of carbon dioxide and relatively little oxygen (0.1-0.8 vol. %), the flue gas from the regeneration zone in accordance with the present invention generally contains less than 0.1, preferably less than 0.05 vol. % carbon monoxide. More specifically, the carbon monoxide content will range from about 5 to about 1000 ppm; preferably from about 300 to about 1000 ppm, and most preferably from about 5 to about 500 ppm. For the practice of this invention, the free oxygen content in the flue gas should be maintained at least 0.4 vol. %, preferably at least 0.8 vol. %. However, the oxygen content may vary from about 0.4 to about 7 vol. %, preferably from about 0.8 to about 5 vol. %, more preferably from about 1 to about 3 vol. %, most preferably from about 1.0 to about 2 vol. %. From an ecological viewpoint, the extremely low level of carbon monoxide in the flue gas stream is highly desirable and meets existing standard for ambient air quality. From a process viewpoint, heat recovery by down stream combustion of carbon monoxide in a boiler is avoided with consequent substantial savings in process equipment and operational cost.
Further, the method for regenerating catalytic cracking catalyst may be applied beneficially to any type of fluid cat cracking unit with little or no modifications and without limitations as to the spatial arrangement of the reaction, stripping, and regeneration zones thereof. The regeneration zone of a catalytic cracking unit can be designed independently from the reaction zone since the regeneration zone merely receives spent catalyst, oxidizes the coke thereon to regenerate the catalyst, and returns the regenerated catalyst to the reaction zone. Therefore, the reaction zone can be a pure transfer line, i.e. one in which the reaction occurs in a single pipe type vessel directly terminating in a cut cyclone or cyclones, a conventional dilute riser/dense bed combination, or a dense bed alone.
Lower temperatures in the regeneration zone, for example temperatures below about 1300° F., are particularly desirable in pure transfer line units since the circulation rate of the catalyst is a major factor in providing the severity of cracking conditions to the cracking reaction. The greater the circulation rate, the greater the holdup in the reaction zone. A lower temperature in the regeneration zone will increase catalyst circulation rate, thereby permitting greater conversion in the riser and/or cracking at lower temperatures in the reaction zone and production of less gas and more liquid product at a given level of conversion.
The following example is presented to illustrate the process of the present invention and is not intended to unduly restrict the limits of the claims appended hereto.
Table 1 contains data obtained in a fluid catalytic cracking operation over a one week period of time which illustrates obtaining a low residual carbon content on regenerated catalyst at elevated temperatures without substantial change in the regeneration gas rate. As shown in the Table, the temperature of the dense phase bed in the regeneration zone is increased at a relatively constant regeneration gas rate by reducing the catalyst circulation rate. The increased temperature has the effect of increasing the rate of removal of coke from the catalyst, thereby establishing a new and lower equilibrium level of residual carbon on regenerated catalyst. In addition, although not shown directly in Table 1, the composition of the flue gas is not changed appreciably until the coke make in the reaction zone is reduced, thus providing an excess of oxygen relative to the amount of coke on the catalyst to oxidize the carbon monoxide to carbon dioxide. This is shown more clearly in Table 2.
Table 2 contains data obtained in the same fluid catalytic cracking operation over a different five day period of time. As mentioned above, as the temperature of the dense phase bed in the regeneration zone is increased, the rate of carbon and carbon monoxide conversion increases without substantial change in the flue gas composition. This is clearly shown in test points 1 and 9. The temperature could have been increased further without the substantial variation in the flue gas composition shown in test points 2-8 had not the coke make in the reaction zone been reduced by decreasing the holdup and/or temperature in said reaction zone thereby favoring less cracking. In test points 2, 3 and 4, the temperature of the dense phase bed is increased with concomitant reductions in the carbon monoxide content of the flue gas. A comparison of test points 2 and 5 shows that the carbon monoxide content of the flue gas may be considerably different for the same dense phase bed temperature depending upon the coke make in the reaction zone; that is, the lower reaction zone temperature in test point 5 relative to that in test point 2, in effect, increases the amount of oxygen in the regeneration zone which is available for further combustion of carbon monoxide to carbon dioxide. Test points 6, 7 and 8 show that as the coke make in the reaction zone is reduced at a high dense phase bed temperature, more oxygen is available in the flue gas to substantially combust the remaining carbon monoxide to carbon dioxide. Table 2 shows that as the temperature of the dense phase bed is increased, the residual carbon on regenerated catalyst tends to decrease.
Table 3 contains data obtained over a three day period subsequent to that shown in Tables 1 and 2 and illustrates reducing the temperature of the dense phase bed while maintaining a low residual carbon on regenerated catalyst, low carbon monoxide flue gas operation without excessive afterburning. As shown, test point 1 corresponds to a three day average before the test period. The temperature in the regeneration zone was reduced by decreasing the temperature in the reaction zone in order to limit the coke make therein. Ordinarily, the circulation rate would be increased to reduce the temperature of the dense phase bed in the regeneration zone. However, in this particular test, the temperature in the reaction zone had to be lowered to such an extent that the catalyst circulation rate required to remove the heat from the regeneration zone was less than that at the elevated temperature. As the temperature of the dense phase bed decreased, the oxygen content in the flue gas was observed to increase gradually from 0 to the 1-1.5 vol. % level. At the same time, the level of carbon monoxide dropped smoothly from 2 vol. % to about 380 ppm. This is shown as test points 1, 2 and 3, respectively. The coke make in the reaction zone was adjusted to a level sufficient to maintain the excess oxygen in the flue gas to ensure the substantially complete conversion of coke to carbon dioxide.
The operation in which the above plant tests were conducted contained two parallel sets of separation means in the regeneration zone. Each set comprised a primary and a secondary cyclone separator in series. With respect to control of the temperature in that portion of the regeneration zone occupied by the substantially catalyst-free flue gas, that is at the outlet of the secondary cyclones, all of the test points shown in Tables 1, 2 and 3 were obtained while a small amount of purge steam was being introduced into one or both sets of cyclone separators. Since steam was added continuously during normal operation of the unit, the addition of purge steam during the plant test period was necessary in order to (1) prevent the accumulation of catalyst in the unused steam line and (2) avoid the formation of water droplets in the unused steam line because the droplets would be sprayed from the steam line when steam flow was resumed, thereby contacting the hot 304 stainless steel comprising said separators and cause fracturing thereof. Thus there was considerable economic incentive to maintain the flow of purge steam during the plant tests. However, the amount of purge steam used had a relatively insignificant effect on reducing the temperature, that is, less than about 5° F., of the secondary cyclone outlet. This small effect may be seen in test points 1 and 4 of Table 3.
An amount of steam additional to the purge steam was added during all but test points 1 and 4 of Table 3 in order to insure control of the temperature therein. This additional steam was added solely as a precautionary measure to insure protection of the materials and catalyst in the unit should undesirably high temperature excursions occur and not of necessity in the practice of the present invention. In fact, points 2 and 3 of Table 3 show that the amount of steam added additional to the purge steam resulted in about 20° F. of cooling of the flue gas leaving the secondary cyclones. Table 3 thus demonstrates that by following the method of the present invention, a flue gas stream containing about 380 ppm of carbon monoxide can be obtained in a dense phase bed temperature of about 1300° F. in the absence of excessive afterburning without the use of extraneous cooling means or variation of the regeneration gas rate.
The present method may also be used to obtain levels of carbon monoxide less than 380 ppm, for example as low as about 1 ppm. However it was not possible to demonstrate such low carbon monoxide operation in this particular operation because there was insufficient analytical equipment available at the time of the plant test for good control of carbon monoxide levels below about 300 ppm.

Nowadays it is quite common to hear the CDC statistic that 1 in 88 children (and 1 in 54 boys) in the US have an Autism Spectrum Disorder. There is much debate about whether there is actually an increase in occurrence or whether we have just gotten better at detection. There is similarly loud debate about the new criteria for ASD in the DSM 5. For the young people I work with, though, the debate is beside the point. What they experience is what matters; and that experience is often isolation, confusion, frustration, anxiety, and depression. Read full post »
This past summer, after being asked for years by both parents and colleagues for resources and materials related to sexuality and autism, I decided to offer a skills group covering everything from hygiene to flirting to understanding different types of relationships. Drawing from a number of resources, including the King County FLASH curriculum for special education students as well as resources written directly for youth with ASD, and probing my colleagues, especially those who have children and teens with autism, I developed a 10 week curriculum and embarked on a true adventure in teaching and learning.

Like so many other aspects of growing up, bullying is a “typical” challenge this has unique dimensions for children with autistic spectrum disorders (ASD) and their caregivers. Due to a number of high-profile cases in the news and the expansion of bullying into the realm of social media, bullying is getting a lot of media attention and as a result, is now appropriately recognized as a public health issue.
An explosion of research on bullying has identified far-reaching impacts not only on victims and perpetrators, but bystanders as well. Bullying is no longer considered socially normative or tolerable, as it once was. The consequences are too dire and far reaching. Victims experience the direct effects of fear, embarrassment, and vulnerability that can impact social and emotional development and impede learning. Furthermore, children with limited communication skills are at risk of expressing the associated distress in potentially harmful ways including self-injury, escape behaviors (running away from individual or situations) and aggression directed at caregivers. Children who observe bullying and parents who feel helpless to protect their children can experience an erosion of their sense of safety. Read full post »

Do children and adolescents with Autism Spectrum Disorder (ASD) spend more time on video games and computers than their peers? According to researcher Dr. Paul Shattuck, the answer is ‘yes’.
Dr. Shattuck, of Washington University in St. Louis, sampled 1,000 study participants who had ASD and found that 41% indicated a level of screen time that would qualify as ‘high user’. The results of the study are telling: “Given that only 18 percent of youths in the general population are considered to be high users of video games, it seems reasonable to infer based on the current results, that kids with ASDs are at significantly greater risk of high use of this media than are youths without ASDs” (Shattuck, 2012).

At age 18, unless guardianship has been established, all US citizens obtain the legal right to vote. Some 18 year olds pay no attention to elections, while others may have more interest in the process. This is true whether a teen has autism or not. How does a parent know if their teen is ready to vote? As a parent you have supported your child through their first 18 years. Ideally you have provided them the right amount of support to be as successful and independent as possible. Over the years you have learned your son or daughter’s strengths and challenges and will have a pretty good idea if your teen is ready to vote. Some of the questions to consider are, does your son/daughter show any interest in the election process, do they ask questions regarding the candidates or ballot measures? If yes, then you can sit down with your teen once the voter’s pamphlet arrives. You will know how much time your teen will spend reading over the information and how much time you should allot for discussion prior to the election. Obtaining a mail in ballot allows the voter to take their time while casting their vote. Read full post »

AUGUSTA, Ga. – The Augusta University baseball team met the West Georgia Wolves for the fifth time in 10 days on Sunday afternoon at Lake Olmstead and drew a bases-loaded hit-by-pitch in the ninth inning to win 4-3 in non-conference action.
Augusta moves to 2-4 on the season, while the Wolves go to 4-2 with the loss.
Senior southpaw-slinger Will Thompson logged 6.0 innings in his second start of the season and struck out four batters while giving up six hits for two runs. Preseason All-Conference honoree Casey Lenoch (1-0) pitched for AU in relief and went 3.0 innings to allow three hits for a run in the win.
The Wolves scored first when Christopher Michels tripled off the left-centerfield wall to score Price Peters in the second inning for a 1-0 UWG lead. Michels added an RBI single in the fourth for a two run lead.
The Jags tied the game with a pair of runs in the fourth inning, when Hobbs hammered home Jim Wagner and Lanford plated Spurlin with back-to-back singles.
With the game tied 2-2 in the eighth, the Wolves added another run when Michels carded his third RBI with a sacrifice fly to centerfield. AU rallied in the next at bat and Adam Spurlin delivered a game-tying, opposite-field single.
Augusta loaded the bases in the bottom of the ninth and Murray was hit by the pitch to win a 4-3 game.
UWG's Russell Klein went 3.2 innings in the start and surrendered four hits for a run and struck out four. Ryan Sapp relieved the Wolves and also went 3.2 innings before Mitchell Mannino made an appearance in the eighth. Colton Duttweiler (1-1) got the loss for UWG.
The Jaguars host crosstown school Paine College on Wednesday, Feb. 15 for a 5:00 p.m. single game at Lake Olmstead.

Following the success of last year’s inaugural event organisers Colin Black and Daniel Alderson have again pulled together a cracking day of established and breakthrough artists.
The festival is headlined by Roscoe Levee and the Southern Slide.
Guitar and Hammond led, with hints of the best of 70’s British and US rocking blues, Rosco Levee & The Southern Slide boil over with flavours of London and the Mississippi.
Also on the bill are Wille and the Bandits, a classic three piece in the vain of Cream or The Jimi Hendrix Experience.
But in a similar way to how these bands pushed the genre in their time, Wille and the Bandits try to take their sound beyond what is expected of such a traditional line up.
Also on the live bill, from 3pm until late, are Kent DuChaine, Brothers Groove, and The Blues Duo.
Veteran blues DJ Chris Powers willspin classic tracks before, during and after the bands.
An intimate gig for 200 appreciative blues fanatics, the organisers are hoping over time to expand and earn a place on the National Blues Circuit.

Posted on March 29, 2017
PXP ENERGY Corp. intends to keep a majority stake in Forum Energy Ltd., a company whose main asset is a controlling interest in an offshore exploration service contract (SC) 72 west of Palawan island in the disputed West Philippine Sea.
In a disclosure to the stock exchange, PXP Energy said it infused $11.805 million into Forum Energy, as it raised its direct interest in the latter to 69.5% from 48.8% previously.
“Additional capital was infused in Forum primarily to fund Forum’s share in the drilling expenses in Galoc 7 well which is expected to commence later this week,” Mark Raymond H. Rilles, PXP Energy’s finance controller, said via e-mail.
“We will proceed to a Phase 3 Galoc development that would entail further drilling of wells if Galoc 7 is successful,” he added.
Directly or indirectly, its interest in the UK incorporated company has reached 77.5% from 67.5% before the transaction took place on March 23. Its indirect stake is through a 54.99%-owned subsidiary, FEC Resources, Inc., a Canadian public company.
“We intend to maintain majority holdings in Forum because this company holds majority interest in SC 72, in addition to SC 14C1 Galoc,” Mr. Rilles said.
Aside from SC 72, Forum also has 100% operating interest in SC 40 in north Cebu held through Forum Exploration, Inc., and minority interests in the SC 6 and SC 14 sub-blocks in offshore northwest Palawan, including a 2.27% interest in the producing Galoc field, held through Forum Energy Philippines Corp.
In a separate disclosure on Tuesday, PXP Energy said Nido Petroleum Ltd., which is part of the Galoc joint venture, mobilized the drillship “Deepsea Metro I” from Labuan, Malaysia to the Galoc 7 well in Block C1 of SC 14 in Northwest Palawan Basin.
“Further updates will be provided once the rig arrives on location at Galoc-7/7ST and commences drilling operations, which is expected to occur on 31 March 2017,” PXP Energy said.
Earlier, PXP Energy Chairman Manuel V. Pangilinan said the atmosphere had become better to resume discussions between the company and China National Offshore Oil Corp. (CNOOC) to jointly explore an area in West Philippine Sea for its potential natural gas reserves.
Forum has been awaiting guidance from the government on the future activity in SC 72, which is covered by the decision handed down by the Permanent Court of Arbitration in The Hague in the Netherlands on July 12, 2016.
The court ruled that Recto Bank, where SC 72 lies, is within the Philippines’ exclusive economic zone as defined under United Nations Convention on the Law of the Sea.
On March 2, 2015, the Department of Energy (DoE) placed SC 72 under force majeure because the contract site falls within the disputed area of the West Philippine Sea, which was the subject of the arbitration process.
Under the terms of the force majeure, exploration work at SC 72 is suspended from Dec. 15, 2014 until the DoE notifies Forum that it may continue drilling.
SC 72 is located offshore west Palawan and covers 8,800 square kilometers and contains the Sampaguita gas discovery.
On Tuesday, shares in PXP Energy were trading higher by 3.13% to P3.29 each.

Kanye West is hashtag winning.
Whether you love her, hate her, or maybe even love to hate her, there’s no denying that his number one trophy wife is a straight stunner. Kim Kardashian has come a mighty long way from her days of being bound 2 her Herve Leger bandage dresses and now knows that clothing doesn’t have to cling to her kurves in order to look sexy.
While out in LA yesterday, she dipped her ass in a gold Michael Costello creation and made the most out of her thigh-high slit. Despite it being a loose-fitting gown, it showed off all her assets with a deep V-neck and was tied to cinch her waist.
She didn’t wake up like this, but, as Beyoncé so eloquently put it, got damn, got damn, got damn!
The hot mama, who would actually prefer to being referred to as a MILF, also wore her favorite suede Saint Laurent pumps, but opted away from accessorizing with the exception of diamond earrings and the “glacier” her hubby put on her hand.
All her mama ever made was trophies, right?

Lancia Flat-4 engine
Lancia introduced its new aluminum flat-4 engine in 1960 for the Flavia. Though it was a pushrod engine, it was advanced for the time. The pushrod version of the Lancia boxer was only ever used in the Flavia, and its derivatives including the Lancia 2000. In 1976, a new overhead cam engine based on a similar layout was designed and brought into production in 2 and 2.5 litre forms fitted to the Gamma.
The original version was the 1500 cc introduced in 1960; it used an 82 mm bore and 71 mm stroke. It was revised on 1963 with a smaller 80 mm bore and a longer 74 mm stroke, thus displacing 1488 cc. A final version was introduced in 1967 with an even longer 80 mm stroke coupled with a 77 mm bore, giving a displacement of 1490 cc. Production ceased in 1970.
The first 1800 was a 1.7 L (1727 cc) introduced in 1962. It used an 88 mm (3.5 in) bore and 71 mm (2.8 in) stroke. One year later it was replaced by a true 1.8 L (1800 cc) engine thanks to a longer 74 mm (2.9 in) stroke. In 1967 appeared the 1816 cc version using an 85 mm stroke with an 80 mm bore.
The 2.0 L (1991 cc) 2000 version was the ultimate Flavia engine. Bore was 89 mm (3.5 in) and stroke was 80 mm (3.1 in) for a good oversquare ratio. In 1971, the 2.0 L produced 115 bhp (86 kW; 117 PS), and in the HF Coupe in 1972 it produced 125 bhp (93 kW; 127 PS). This engine was produced from 1968 through 1974.
Lancia developed the large light-alloy overhead camshaft 2.0-litre and 2.5-litre flat-4 engines specifically for the Lancia Gamma, rather than using Fiat derived engines as used in the Beta and Montecarlo and were in production between 1976 and 1984.
Replacing the 2.0 L pushrod engine used in the Flavia, the new 2.0 L OHC (1999 cc) engine produced 120 bhp (89 kW; 122 PS) at 5500 rpm and 172 N⋅m (127 lb⋅ft) torque at 3500 rpm.
The 2.5 L (2484 cc) engine was initially available with twin-choke Weber carburettors, but in the last few years of production it was equipped with fuel injection. In both forms, it produced 140 bhp (104 kW; 142 PS) at 5400 rpm and 208 N⋅m (153 lb⋅ft) torque at 3000 rpm.

Lancia's four has its cylinders horizontally opposed, à la Porsche (or VW Beetle if you're uncharitable)--except it's watercooled, hanging out over the nose, and driving the front wheels. Power, even at 92hp, was far beyond VW's modest output in those days, even allowing for the displacement discrepancy.

Joe Budden is coming back to dust off these microphones that need some love! The Hip-Hop veteran is stepping out of retirement to bring some heat to the rap game. A report from The Source indicates that Joe Budden is aiming at the BET cipher as his revamp.
Aweeeee mannnn!!! Yall young spitters done made the oldhead come back.
As of now, it has not be confirmed, but rumors and reports highly speculate it
The BET Awards is set to air on October 16th, 2018.


Recently, some customers and friends have asked why DTF heat transfer prints warp after pressing. If warping occurs, how should we correct or remedy it? Today the manufacturer of TODOjet will tell you more about this! Warping of DTF heat transfer printing is caused by the following reasons: material problems, improper pressing temperature, insufficient pressing time, and equipment problems.
1. Material problem: DTF heat transfer printing is done on the surface of the fabric. The fabric material is not suitable for heat transfer. The hot pressing process will cause the fabric to deform or shrink, resulting in edge distortion.
2. Improper heat pressing temperature: In DTF heat transfer printing, hot pressing temperature that is too high or too low will cause edge distortion problems. If the temperature is too high, the fabric will be excessively deformed; if the temperature is too low, the heat transfer adhesive will be insufficient and cannot be firmly bonded.
3. Insufficient heat pressing time: When DTF heat transfer printing is pressed, if the hot pressing time is too short, the heat transfer adhesive will not melt completely and penetrate into the fabric fibers, and the heat transfer will not be firmly fixed, resulting in distortion.
4. Equipment problems: Equipment problems such as inaccurate temperature control, uneven pressure or uneven ironing head of the DTF heat transfer printing machine will cause uneven heat transfer, resulting in edge warping. To avoid the problem of DTF heat transfer warping, you can consider the suitability of the material when selecting fabrics and heat transfer designs, and ensure that the appropriate heat transfer temperature and time are used.
In addition, what is the reason for using reliable quality DTF heat transfer that warps the edges? Heat transfer equipment and proper operation can also help reduce the occurrence of warping problems. In practice, it is best to test a small piece of fabric first to determine the best heat transfer parameters. If you find edge distortion problems after pressing, you can press again to achieve the desired effect.

Broomfield will get a taste of Broadway today through Friday, when Broomfield High School Thespian Troupe 874 brings its Neil Simon Festival 2012 to the stage.
The shows, which are at 7 p.m. nightly, will fete iconic playwright and screenwriter Simon with scenes and monologues from 10 of his works, including “The Odd Couple,” “Barefoot in the Park” and “Brighton Beach Memoirs,” as well full performances of “Lost in Yonkers.”
The 20-some-member troupe has been rehearsing for the festival since November.
A unique aspect of the shows is the seating, which will be on stage, providing for an intimate theater experience, said BHS drama teacher Rob Scott.
Because traditional seating has been nixed for the more up-close arrangement, only 70 seats are available at each show. And while tickets will be available at the door, Scott advised those who wish to attend to order their tickets online. Advance tickets purchased online cost $7 for students and seniors and $8 for adults. To purchase, click here and then click on the Seat Yourself link.


VELOCITY GRADIENTS AS A TRACER FOR MAGNETIC FIELDS
Strong Alfvénic turbulence develops eddy-like motions perpendicular to the local direction of magnetic fields. This local alignment induces velocity gradients perpendicular to the local direction of the magnetic field. We use this fact to propose a new technique of studying the direction of magnetic fields from observations, the Velocity Gradient Technique. We test our idea by employing the synthetic observations obtained via 3D MHD numerical simulations for different sonic and Alfvén Mach
... rs. We calculate the velocity gradient, Ω, using the velocity centroids. We find that Ω traces the projected magnetic field best for the synthetic maps obtained with sub-Alfvénic simulations providing good point-wise correspondence between the magnetic field direction and that of Ω. The reported alignment is much better than the alignment between the density gradients and the magnetic field and we demonstrated that it can be used to find the magnetic field strength using the Chandrasekhar-Fermi method. Our study opens a new way of studying magnetic fields using spectroscopic data.

From the pen and musical genius of Tim Rice and Andrew Lloyd Webber, the iconic production Evita took to the stage at the Millennium Forum and received a standing ovation on opening night.
Evita tells the story of Eva Peron, the wife of former Argentine dictator Juan Peron. It follows her journey from humble beginnings, to her extraordinary wealth, power and iconic status which ultimately lead her to be heralded as the 'spiritual leader of the nation' by the Argentine people.
It felt as if we were transported to London’s West End for the evening. The very stage of the Forum seemed to expand and caress the cast, as the lighting and beautiful set helped to make the audience feel part of this excellent production which was littered with amazing performances.
I can truly say that this was a musical in its purest form. The narration and interaction between all of the characters were entirely conveyed through song. With iconic classics such as ‘Don't Cry For Me Argentina’, ‘On This Night Of A Thousand Stars’, ‘You Must Love Me’, and ‘Another Suitcase in Another Hall’, the crowd had their fill of pleasers.
The performance was slick and the pace was full on as we were kept on our toes while watching the events unfold. The stage props seemed to glide with their own graceful dance movements across the floorboards, as the set was transformed throughout without the need for any pause in the flow of the action. It was a masterpiece of a production.
The performances of the cast members were superb. They never missed a beat and the calibre of the the singing was excellent. It was pure, clear and magical to listen to. Led by three of the finest musical theatre stars, were Lucy O’Byrne who performed the iconic role of Eva Perón, Mike Sterling as her husband and Argentine President Juan Perón and Glenn Carter as Ché.
The musical accompaniment of an orchestra in the pit, also added to the quality of the performance and the feel of a West End show right here in our own local theatre.
I thoroughly enjoyed this wonderful production of Evita as did the rest of audience which was evident from the standing ovation and exuberant clapping and cheering at the end of the evening.
One of the biggest cheers of the night however went to a local talent A very gifted young girl from the Foyle School of Speech and Drama who performed a solo that was worthy of any London stage. It was wonderful to see so much homegrown talent on show as students from the North West Regional College also helped to bolster the stage numbers, and excel alongside their West End counterparts.
On seeing this great production, it was obvious as to why Evita has been on the receiving end of five star reviews throughout the tour. A musical theatre classic which has been beautifully performed.
Evita runs at the Millennium Forum until Saturday 13th October. Book your tickets here.


Tom Cruise is known for his daredevil stunt in the new Mission: Impossible – Rogue Nation, but on Monday night, the actor relived his Rock of Ages days in a lip sync battle with Jimmy Fallon on The Tonight Show. Tom, 53, gamely stepped up to the microphone to lip sync two songs – and he certainly impressed.
"This is so ridiculous. I love it," Tom laughed before miming along to his first song, "Can't Feel My Face" by The Weeknd to the delight of the audience. It was then host Jimmy's turn, and he countered with a cover of the Rolling Stones classic "Undercover of the Night," imitating Mick Jagger's trademark strut and singing style.

The Mission: Impossible star pulled out all the stops for his second song with a one-man duet of Meat Loaf's "Paradise By The Dashboard," performing both the male and the female parts. There was really only one option for the last song – The Righteous Brothers' "You've Lost That Loving Feeling," which Tom famously sang in Top Gun. Jimmy and Tom teamed up as they mimed along to the track together and serenaded one lucky lady in the audience.
Tom recently admitted that he would love to reprise the role of Maverick in a sequel to the iconic 80s movie. "It would be fun," he told EXTRA. "I would like to get back into those jets. It would have to be practical. I don't want any CGI jets. I want to shoot it like how we shot the first one."
Tom is currently on the promotional trail with his new film Mission: Impossible – Rogue Nation, which has received rave reviews from critics. On Monday night, he hit the New York City premiere along with Jeremy Renner and Alec Baldwin.
