Abstract: Vent gases from a catalyst cooler are directed downstream or outside of the catalyst regenerator to avoid sending air to a location where after burn may occur. Vent gases contain oxygen that when contacted with carbon monoxide in regenerator flue gas can cause after burn to occur at a location which lacks sufficient catalyst density to serve as a heat sink. Locating the cooling media supply in the top of the catalyst cooler enables cooled catalyst to drain from the bottom of the catalyst cooler and fitting more cooler tubes in the catalyst cooler.

Abstract: This present disclosure relates to apparatuses for methylation of aromatics in an aromatics complex for producing a xylene isomer product. More specifically, the present disclosure relates to apparatuses for producing para-xylene by the selective methylation of toluene and/or benzene in an aromatics complex using processed toluene instead of crude toluene.

Abstract: A power generation process for use in a processing unit that includes the steps of: using a regenerator to produce a flue gas stream; removing catalyst particles from the flue gas stream; routing the flue gas stream to a combustor/expander unit after performing the step of removing catalyst particles; and using rotation of the turbine of the combustor/expander unit as a source of rotary power. Preferably, the combustor/expander unit includes a combustion chamber and a power recovery turbine housed within a single casing. In certain embodiments, the flue gas stream is routed between the regenerator and the combustor/expander without passing through a compressor.

Abstract: A baffle is installed on the wall of a regenerator vessel to push catalyst away from the wall to ensure adequate exposure to regeneration gas and complete combustion of coke from the catalyst. We have found that in deep beds, catalyst can flow down the walls and escape sufficient exposure to regeneration gas and undergo too little regeneration.

Abstract: One exemplary embodiment can be a process for separating particulate solids from a gas stream. The process can include regenerating a catalyst in a regenerator, separating particulate solids in first and second cyclone stages, passing the gas stream from the second cyclone stage to an external third stage separator, and passing the gas stream from the external third stage separator to a cyclone recirculator to obtain a clean gas stream.

Abstract: A process and apparatus for indirect heating of catalyst in the regeneration zone is disclosed. A hot flue gas flows within a heating tube and the catalyst to be heated flows outside the heating tube. The hot flue gas is generated by igniting a fuel stream. The hot flue gas is generated directly in the heating tube or is generated in a separate burner outside the heating tube.

Abstract: A fluidized catalytic reactor decouples the catalyst regenerator temperature from the catalyst reactor residence time. Regenerated catalyst is cooled before it contacts reactant feed. The regenerated catalyst may be cooled by heat exchange with oxygen supply gas, spent catalyst or other materials. The process and apparatus are especially useful for fluidized endothermic catalytic reactions.

Abstract: An apparatus and process is disclosed for mitigating coking in an FCC reactor plenum. The apparatus and process utilize a baffle to create a inner volume for the product vapors to prevent contact with a relatively cool plenum. The baffle also limits the amount of the time the product vapors spend in the plenum minimizing time for coke formation and limit product vapors from entering low fluidization zones.

Abstract: Disclosed is a process and apparatus for recycling flue gas from a regenerator back to the regenerator to provide fluidization gas needs. Catalyst may be separated from the flue gas before recycle and the flue gas may be compressed before recycle to the regenerator. The process and apparatus reduces the size capacity of downstream product recovery equipment by reducing gases derived by oxidation in the process and reduces the potential for after burn in the regenerator.
