Method and apparatus for the absorption of hydrogen sulphide and carbon dioxide contained at least, pressurized natural gases by means of physically acting absorbent, wherein the acid gas is passed first into an absorption column containing natural gas, where it is brought into direct contact with the physical detergent absorbed on a radical and the physical Detergent the acid gas to, the loaded scrubbing medium is passed into a first separator while lowering the operating pressure, by means of a part of the dissolved from the detergent [...]outgasses, the at least a portion of the loaded cleaning agent is passed to a stripping column under them again lowering of the operating pressure, in which the rest of the dissolved from the detergent [...] is expelled and the thus regenerated detergent is returned at least partially to the absorption column is passed into a further absorption column the first separator abandoned acid gas, a predominantly hydrogen sulfide-containing part of the degassed in the with regenerated scrubbing [...]backabsorbed and the loaded washing agent is mixed with said first separator, the remaining, not from the the first separator is recovered as stripping gas backabsorbed acid gas downstream absorption column, this stripping gas in the stripping column for the removal of the hydrogen sulphide in the washing agent, which of the stripping column...
