Abstract: Embodiments of apparatuses and methods for removing deposits in thermal conversion processes are provided herein. In one example, a method comprises advancing a hot vapor through a hot vapor inlet tubular section to a low temperature zone inlet nozzle of a longitudinal tubular section. The hot vapor inlet tubular section has a first inner diameter and the longitudinal tubular section has a second inner diameter that is greater than the first inner diameter. A ram head with a net open cross-sectional flow area is moved between a retracted position and an extended position to remove the deposits in the low temperature zone inlet nozzle.

The catalyst distributor comprises a header and a nozzle, the header and the nozzle are in fluid communication with the catalyst pipe for distributing coked catalyst to the vessel. The header comprises a header and a plurality of nozzles including an angular nozzle projecting at an angle to a longitudinal axis of the header. The process comprises delivering coked catalyst from a catalyst pipe to the catalyst distributor wherein the catalyst distributor discharges the coked catalyst from at least two sides of the catalyst pipe into the regenerator vessel.

Abstract: An oxygen gas stream is distributed to a spent catalyst stream through an oxygen nozzle of an oxygen gas distributor and a fuel gas stream is distributed to the spent catalyst stream through a fuel nozzle of a fuel gas distributor. An oxygen gas jet generated from said oxygen nozzle and a fuel gas jet generated from said fuel gas nozzle have the same elevation in the regenerator. In a regenerator, an oxygen gas distributor and a fuel gas distributor may be located in a mixing chamber. A fuel outlet of a fuel nozzle of the fuel gas distributor may be within a fifth of the height of the mixing chamber from an oxygen outlet of an oxygen nozzle of the oxygen gas distributor. In addition, clear space is provided between a fuel gas nozzle on a fuel gas distributor and a closest oxygen nozzle on an oxygen gas distributor.

Abstract: A process for catalytic production of olefins comprises contacting a first hydrocarbon stream and a first stream of fluid catalyst in a first riser to produce a first cracked product stream and a spent catalyst stream. The first cracked product stream is separated in a main column. An overhead stream from the main column is separated into a second hydrocarbon stream. The second hydrocarbon stream is contacted with a second stream of fluid catalyst in a second riser to produce a second cracked product stream and a first stream of cool catalyst. A third hydrocarbon stream is obtained from the overhead stream and/or from the second cracked product stream. The third hydrocarbon stream is contacted with a third stream of fluid catalyst in a third riser to produce a third cracked product stream and a second stream of cool catalyst.

Abstract: In an FCC apparatus and process structured packing should be located at the very top of the stripping section in an upper region. The lower region below the structural packing may be equipped with fluidization equipment such as stripping media distributors and one or more gratings. This arrangement enables stripping of entrained hydrocarbons off the incoming catalyst immediately upon entry into the stripping section allowing the entrained hydrocarbon to exit the stripping section with minimized residence time to minimize post-riser cracking. Revamp of stripping sections with tall stripping sections should conducted in this way to improve performance and reduce down-time for equipment installation.

Abstract: A process and apparatus for heating catalyst is presented. Cooler catalyst is removed from a reactor and heated with a hot gas in a riser, heated in a heating tube or heated in a heating chamber. Heated catalyst is disengaged from the hot gas if necessary and returned to the reactor. The process and apparatus can be used for producing light olefins. The hot gas may be a flue gas from an FCC regenerator or a combustion gas from a heater.
