Abstract

Two absorbent solution streams are laden with CO.sub.2 and optionally with COS, which are physically dissolved. The COS content of the second absorbent solution stream is at least three times the COS content of the first absorbent solution stream. For regeneration, the first absorbent solution stream is pressure-relieved into a first pressure relief zone so as to reduce the pressure by at least 2 bars and to flash off a gas which contains CO.sub.2. The second absorbent solution stream is pressure-relieved at least in part into a second pressure relief zone, which contains exchange-promoting elements. The flashed-off gas from the first pressure relief zone is passed through the second pressure relief zone in a countercurrent to the second absorbent solution stream. The second pressure relief zone is preferably disposed over the first pressure relief zone and the second absorbent solution stream flows first through the second and then through the first pressure relief zone.
