    Abstract: The invention relates to a method for separating C5-C8 hydrocarbons and acid gases from a fluid stream. According to said method: a) the fluid stream is brought into contact with an absorbent containing at least one amine, in an absorption zone, producing a de-acified fluid stream and an absorbent charged with acid gases; b) the charged absorbent is heated in a first heat exchanger and is expanded in a de-compression zone to a pressure of between 5 and 10 bar, producing a gas phase containing C5-C8 hydrocarbons and a charged absorbent stripped of hydrocarbons; c) the charged absorbent stripped of hydrocarbons is heated in an optional second heat exchanger and is fed into a stripper, in which the acid gases are at least partially released at a pressure of between 1 and 2.5 bar by supplying heat, producing a re-generated absorbent and a stream containing acid gas; and d) the re-generated absorbent is fed back into the absorption zone. The re-generated absorbent is used as the heating medium in the second heat exchanger and is used as the heating medium in the first heat exchanger after passing through the second heat exchanger. The relative quantities of heat transferred in the first heat exchanger and in the second heat exchanger are weighted such that the gas phase containing C5-C8 hydrocarbons contains between 50 and 97 vol.-% acid gases.
