## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The vessel of claim 1 wherein the first grid and the second grid in the first section include a plurality of openings to allow catalyst to pass therethrough.

### Claim 3 (depends on 1)

The vessel of claim 1 wherein segments are secured to each other with a sleeved connection.

### Claim 4 (depends on 1)

The vessel of claim 1 wherein the first segment has an upper leg that passes above the first grid and is secured to the intermediate segment and a lower leg that passes below the first grid.

### Claim 5 (depends on 4)

The vessel of claim 4 wherein the lower leg is secured to a pipe that is supported on a second section that may comprise a structural packing.

### Claim 6 (depends on 4)

The vessel of claim 4 wherein the first segment is welded to a plate that is welded to the first grid.

### Claim 7 (depends on 5)

The vessel of claim 5 further comprising at least one gas inlet for admitting a gas disposed below the second section.

### Claim 8 (depends on 7)

The vessel of claim 7 further comprising 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.

### Claim 9 (depends on 1)

The vessel of claim 1 further comprising a lug secured to a wall of the vessel and a notch in the first grid engages said lug.

### Claim 10

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.

### Claim 11 (depends on 10)

The vessel of claim 10 wherein the first segment has an upper leg that passes above the first grid and is secured to the intermediate segment and lower leg that passes below the first grid.

### Claim 12 (depends on 11)

The vessel of claim 11 wherein the lower leg is secured to a pipe that is supported on the second section.

### Claim 13 (depends on 11)

The vessel of claim 11 wherein the first segment is welded to a plate that is welded to the first grid.

### Claim 14

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 comprising 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.

### Claim 15 (depends on 14)

The vessel of claim 14 wherein segments are secured to each other with a sleeved connection.

### Claim 16 (depends on 14)

The vessel of claim 14 wherein the first segment has an upper leg that passes above the first grid and is secured to the intermediate segment and lower leg that passes below the first grid.

### Claim 17 (depends on 16)

The vessel of claim 16 wherein the lower leg is secured to a pipe that is supported on a second section that may comprise a structural packing.
