Abstract: A fluid catalytic cracking reactor including a vessel, a chamber housed within the vessel, and a plurality of cyclones housed within the vessel, but externally of the chamber. The plurality of cyclones are arranged in a plurality of cyclone clusters, where each of the cyclone clusters includes a grouping of at least two cyclones that share common outlet piping for communication with the chamber. Alternatively, a fluid catalytic cracking reactor including a vessel, a chamber housed within the vessel, and a plurality of catalytic separation devices housed within the vessel, but externally of the chamber. The catalytic separation devices are in communication with the chamber via outlet piping. Preferably, the catalytic separation devices of the reactor are also in communication with a plenum via separator gas outlet piping, and optionally at least one of the catalytic separation devices feeds an outlet vapor stream into at least two different separator gas outlet piping members.

Abstract: A regenerator for an FCC apparatus. The regenerator includes an internal riser inside of a outer shell. The internal riser includes a cone and a cone skirt. An annulus is formed between the internal riser and the outer shell. A sealing apparatus for keeping catalyst out of a portion of the annulus comprises a first sealing element and a second sealing element disposed above the first sealing element. An annular trough in the annulus below the primary seal is filled with material that has a heat transfer coefficient at least as high as air to allow heat to get to the inner surface of the outer shell.

Abstract: A process and apparatus for combusting coke from catalyst two stages is disclosed. Catalyst and flue gas from a lower chamber ascends to an upper chamber to be roughly separated by swirl ducts extending from a combustion conduit. The swirl ducts may discharge into a container in the upper chamber.

CPC classification number: C10G11/18
Abstract: A process and apparatus described is for distributing fluidizing gas to a riser. Fluidizing gas is delivered to a plenum below the riser. A first stream of fluidizing gas is distributed from the plenum into a chamber in a riser and a second stream of fluidizing gas is distributed from the plenum into the riser outside of the chamber. First nozzles in the plenum have a first outlet in the chamber and second nozzles in the plenum have a second outlet outside of the chamber. Streams of regenerated catalyst and carbonized catalyst may be passed to the riser and mixed around the chamber in a lower section of a riser.
