Abstract

A heat exchanger for cooling particulate matter from a high-temperature industrial process or warming material from a cryogenic process is disclosed. The heat exchanger comprises a structure comprising a rectangular frame, piping that is supported by the rectangular frame and completes at least one circumference around the rectangular frame, and a fan. The piping is supported to the frame on a series of moving supports. The piping comprises an inlet end and an outlet end, and the piping contains external cooling fins. The structure is sealed except for where the finned piping is located.

Claims

1. A heat exchanger for cooling particulate matter from a high-temperature industrial process or warming material from a cryogenic process, said heat exchanger comprising:

(a) a structure comprising a rectangular frame;

(b) piping that is supported by the rectangular frame and completes at least one circumference around the rectangular frame, wherein the piping is supported to the rectangular frame on a series of moving supports, and the piping comprises an inlet end and an outlet end, and the piping contains external cooling fins; and

(c) one or more fans to circulate air across the piping in order to warm or cool the particulate matter or material that move through the piping;

wherein the structure is sealed except for where the piping is located and at an opening to an exhaust vent connected to the one or more fans; and

the outlet end of the piping is connected to one or more collection vessels.

2. The heat exchanger of claim 1, wherein each piping circumference contains at least one corner, and at each corner of each piping circumference, the piping is connected with a pipe tee having one end sealed.

3. The heat exchanger of claim 1, wherein the one or more fans are centrally located on the structure above the piping.

4. The heat exchanger of claim 1, wherein the particulate matter comprises catalysts and/or additives from a regenerator of a fluid catalytic cracking (FCC) process.

5. The heat exchanger of claim 1, wherein the material from the cryogenic process comprises a product of a pharmaceutical manufacturing process.

6. The heat exchanger of claim 1, wherein the particulate matter comprises catalysts and/or additives from a methanol conversion process.

7. The heat exchanger of claim 1, wherein the moving supports are spring hangers or sliding plates.

8. The heat exchanger of claim 1, wherein the heat exchanger is supported off the ground on one or more legs.

9. The heat exchanger of claim 1, wherein the outlet end of the piping is connected to two or more collection vessels.

10. The heat exchanger of claim 1, wherein the rectangular frame is in the shape of a square.
