18 ABSTRACT OF THE DISCLOSURE For the purification of hydrocarbon-containing, e.g., methane raw gases containing H2S and CO2, the raw gas is dried, and separated by rectification into a hydrocarbon-rich overhead fraction containing some H2S and CO2 and into a bottom fraction consisting essen- tially of H2S and CO2. The overhead product is freed, in a first scrubbing column, of the acidic components with a physical acting scrubbing medium selective for H2S and COS as against CO2, e.g., polyethylene glycol ether or toluene. The bottom product from the rectifi- cation step is vaporized and selectively desulfurized in a second scrubbing column with the same scrubbing medium, and the scrubbed gas from the second scrubbing column is discharged as CO2 under pressure.
