Abstract
In a process for the purification of coal gasification gases, synthesis gas and fuel gas are simultaneously produced. In order to obtain a fuel gas rich in CO.sub.2, capable of handling fluctuations in demand, and to produce at the same time a highly concentrated H.sub.2 S fluid fraction, a portion of the crude gas, scrubbed to synthesis gas purity, is utilized for stripping out CO.sub.2 under pressure from scrubbing medium loaded exclusively with CO.sub.2. The partially stripped CO.sub.2 -loaded scrubbing medium is employed for the concentration of sulfur compounds in an H.sub.2 S/COS-loaded scrubbing medium.
