摘要：
The invention relates to a method for treating a process gas flow containing CO
2 that is produced whilst producing pure synthesis gas from the crude gas of the process gas flow or during the partial oxidation of heavy olis, petroleum cokes and waste substances or during coal gasification or during the treatment of natural gas or gas which accompanies petroleum, from which CO
2 is removed by physisorption or chemisorption and the solvent charged with CO
2 is released at a low pressure for the desorption of the CO
2 . In order to produce CO
2 as pure as possible, the unpurified CO
2 is compressed at least at 60 bar[a] or below the critical temperature thereof to at least 70 bar[a] and the impurities contained in the liquid CO
2 are removed by stripping with gaseous CO
2 guided into the counter flow.
