"PROCESS FOR OBTAINING C2+ OR C3+ HYDROCARBONS FROM GASEOUS MIXTURES" Abstract of the Disclosure A process is disclosed for obtaining C2+ or C3+ hydrocarbons from hydrocarbon-containing gaseous mixtures by pressure scrubbing with a physically acting solvent selective for C2+ and, respectively, C3+ hydrocarbons. The solvent, after loading, is regenerated and reused. In order to avoid impurities in the C2+ and, respectively, C3+ 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 con- comitantly 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 exhi- bit a low concentration of components to be scrubbed out.
