Abstract: A process for removing C5-C8-hydrocarbons and acid gases from a fluid stream is described, where a) the fluid stream is brought into contact with an absorption medium comprising at least one amine in an absorption zone to obtain a deacidified fluid stream and an acid-gases-laden absorption medium, b) the laden absorption medium is heated in a first heat exchanger and decompressed into a decompression zone to a pressure of from 5 to 10 bar to obtain a C5-C8-hydrocarbons-comprising gas phase and a hydrocarbon-depleted laden absorption medium, c) the hydrocarbon-depleted laden absorption medium is heated in an optional second heat exchanger and passed into a stripper in which at a pressure of 1 to 2.5 bar the acid gases are at least partially liberated by supplying heat to obtain a regenerated absorption medium and an acid-gas-comprising stream, and d) the regenerated absorption medium is recycled into the absorption zone.
