ABSTRACT:
A method for the recovery of a methane-rich natural gas from a natural gas containing, apart from methane, also hydrogen sulfide, carbondioxide, higher hydrocarbons and, in most cases, organosulfur compounds. According to the invention a hydrocarbon fraction of C.sub.4 hydrocarbons and higher is naturally removed from the natural gas which is then subjected to a selective scrubbing for the removal of hydrogen sulfide with a regeneratable extraction, of scrubbing liquid. Next a C.sub.3 fraction is removed, the remaining gas being scrubbed with a second regeneratable washing agent, for the removal of carbondioxide to leave the methane-rich gas.
