For purifying coal gasification gases with simultaneous production of synthesis gas and fuel gas, and for obtaining a CO2-rich fuel gas with good flexibility and simultaneously producing a highly concentrated H2S fraction, a part of the raw gas scrubbed to the purity of synthesis gas is used for stripping CO2 under pressure out of the scrubbing agent loaded exclusively with CO2, whereupon the scrubbing agent loaded with CO2 is used for concentrating sulphur compounds in the scrubbing agent loaded with H2S/COS. |
