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.

Abstract: A process is disclosed for obtaining C.sub.2+ or C.sub.3+ hydrocarbons from hydrocarbon-containing gaseous mixtures by pressure scrubbing with a physically acting solvent selective for C.sub.2+ and, respectively, C.sub.3+ hydrocarbons. The solvent, after loading, is regenerated and reused. In order to avoid impurities in the C.sub.2+ and, respectively, C.sub.3+ product in an economical and energy-saving way, the loaded solvent is subjected to expansion to a pressure lying below the critical pressure of the solvent-gas mixture, and to heating and partial evaporation in order to drive off concomitantly dissolved inert gases. The solvent, reduced in its content of inert gases, is then to be passed on to regeneration. The process is advantageous, in particular, in cases where crude gases are to be processed which exhibit a low concentration of components to be scrubbed out.
