Abstract: A process and a device for treating a carbon dioxide-containing flue gas stream are described. At least a part of the carbon dioxide present is removed from the flue gas stream by means of a scrubber, forming a low carbon dioxide gas stream and a high carbon dioxide gas stream. The high carbon dioxide and water-saturated gas stream formed from the flue gas stream after removal of the carbon dioxide is cooled by means of a refrigeration system 4 in a heat exchanger 3 below the dew point temperature of the water contained in the gas stream and dried by condensing and separating out the water in a condensate separator 5. The dried gas stream meets the requirements of carbon dioxide products intended for further use.

Abstract: A process and an apparatus for the treatment of a carbon dioxide-containing flue gas stream are described, at least part of the carbon dioxide present being removed from the flue gas stream in a separating device having in particular an absorption column 7 with the formation of a gas stream having a low carbon dioxide content and a carbon dioxide-rich gas stream. For overcoming the pressure drop caused by the carbon dioxide removal in the absorption column 7, it is proposed that the gas stream having a low carbon dioxide content and formed after the removal of the carbon dioxide from the flue gas stream is subjected to a gas stream compression, for example by means of a flue gas blower 14.
