Down-flow direct contact cooler
First Claim
1. A gas conditioning system configured for down-flow of a feed gas, comprising:
- a housing having an inlet conduit disposed within an upper portion and configured to receive a first stream that is substantially depleted of SOx;
first and second stages disposed within the housing, wherein the first stage is disposed upstream of the second stage and includes a first cooling stream, and wherein the second stage includes a second cooling stream that is colder than the first cooling stream;
wherein the first cooling stream comprises at least some of a spent portion of the second cooling stream and at least some of a spent portion of the first cooling stream; and
wherein the housing is configured such that the first stream is cooled by down-flow heat exchange with the first and second cooling streams to produce a cooled stream depleted of at least a portion of liquid condensed from the feed gas.

Abstract
Systems and methods are contemplated for down-flow cooling of a feed gas. Contemplated systems can include a housing having an inlet conduit disposed within an upper portion and configured to receive a first stream. First and second stages can be disposed within the housing, with the first stage disposed upstream of the second stage and having a first cooling stream, and the second stage having a second cooling stream that is colder than the first cooling stream. The housing can be configured such that the first stream is cooled by down-flow heat exchange with the first and second cooling streams to produce a conditioned stream depleted of at least a portion of water condensed from the feed gas.

14. A method of down-flow cooling of a feed gas, comprising:
-
receiving a first stream in an upper portion of a vessel that is substantially depleted of SOx; subsequently cooling the first stream by down-flow heat exchange with a first cooling fluid and a second cooling fluid to produce a conditioned stream depleted of at least a portion of liquid condensed from the feed gas; wherein the first cooling fluid comprises at least some of a spent portion of the first cooling fluid; and wherein the second cooling stream is colder than the first cooling stream. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A gas conditioning system configured for down-flow of a feed gas, comprising:
-
a housing having an inlet conduit disposed within an upper portion and configured to receive a first stream from an acid gas removal system fluidly coupled to the inlet conduit; first and second stages disposed within the housing, wherein the first stage is disposed upstream of the second stage and includes a first cooling stream, and wherein the second stage includes a second cooling stream that is colder than the first cooling stream; a third stage disposed within the housing, wherein the third stage is disposed downstream of the second stage and includes a third cooling stream that is colder than the first cooling stream; wherein the third cooling stream comprises at least one of a portion of a spent first cooling stream and a portion of a spent second cooling stream; and wherein the housing is configured such that the first stream is cooled by down-flow heat exchange with the first, second and third cooling streams to produce a cooled stream depleted of at least a portion of liquid condensed from the first stream. - View Dependent Claims (26, 27, 28)
