  • 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.
