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 vessel provides for removing hydrocarbons from a catalyst. In an FCC unit, the vessel includes first and second sections. The first section includes at least one grid having a plurality of intersecting members and openings therebetween. The second section includes structured packing such as a plurality of ribbons. Grids are supported by pipes that are supported by the second section.
