Device and method for separating carbon dioxide from a gas stream, in particular from a flue gas stream, comprising a cooling water system

摘要

The invention relates to a device (1) for separating carbon dioxide from a gas stream, in particular from a flue gas stream, comprising an absorber (3) for separating the carbon dioxide from the gas stream by means of a washing medium, a desorber (5) which is fludically connected to the absorber (3) to release the absorbed carbon dioxide from the washing medium, a gas cooler (7) which is fludically connected upstream of the absorber (3) to cool the gas stream, and a processing unit (9) which is connected downstream of the gas cooler (7) and which is equipped and designed to clean water from the gas cooler (7). The invention also relates to a method for separating carbon dioxide from a gas stream.
