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.
Claims17
A vessel for removing hydrocarbons from catalyst, the vessel comprising:
- a catalyst inlet configured to receive a stream of spent catalyst particles, at least some of the spent catalyst particles comprising entrained hydrocarbons;
- a first section, the first section including a first grid and a second grid, each grid including at least one opening to allow catalyst to pass there through, a pipe secured to the first grid and supporting the second grid, wherein the pipe comprises three segments:
- a first segment secured to the first grid, an intermediate segment secured to the first segment and a second segment secured to the second grid;
- and
- an outlet configured to pass catalyst particles from the vessel.
A vessel for stripping hydrocarbons from catalyst, the vessel comprising:
- a catalyst inlet configured to receive a stream of spent catalyst particles, at least some of the spent catalyst particles comprising entrained hydrocarbons;
- a first section, the first section including a first grid and a second grid, each grid including at least one opening to allow catalyst to pass there through, a pipe secured to the first grid and supporting the second grid, wherein the pipe comprises three segments:
- a first segment secured to the first grid, an intermediate segment secured to the first segment and a second segment secured to the second grid and wherein the segments are secured to each other with a sleeved connection;
- a second section, the second section including a structured packing comprised of a plurality of ribbons, the second grid in the first section being spaced from the structured packing of the second section;
- a gas inlet for admitting a stripping gas disposed below the second section;
- and
- an outlet configured to pass catalyst particles from the stripping vessel.
