US 2025/0083085 A1 · Method And Device For Treating Process Air

Abstract

The invention relates to a method for treating process air from an industrial process involving a main flow, wherein at least a proportion of the process air is treated using the following method steps: a first condensation step, in which a first condensate is separated out of the process air and is fed to a first recovery process; and a second condensation step, which takes place after the first condensation step and in which a second condensate is separated out of the process air and is fed to a second recovery process, wherein the lowest process air temperature that is reached in the second condensation step is lower than the lowest process air temperature that is reached in the first condensation step.

Dependent claims

A method of treatment of process air from an industrial process having a main stream (5), wherein at least a portion of the process air is treated by the following method steps:

a first condensation step (41) in which a first condensate (16) is separated out of the process air and fed to a first recovery process (42),
a second condensation step (51) that takes place after the first condensation step (41), in which
a second condensate (17) is separated out of the process air and fed to a second recovery process (53),
wherein the lowest process air temperature attained in the second condensation step (51) is lower than the lowest process air temperature attained in the first condensation step (41).
