Process for deacidifying a hydrocarbon stream containing CO2 and/or further acidic gases as impurities comprises contacting the stream with an absorbing liquid; separating the purified stream and the absorbing liquid charged with CO2 and/or acidic gases; regenerating the absorbing liquid; and feeding to an absorption and/or extraction zone. Process for deacidifying a hydrocarbon stream containing CO2 and/or further acidic gases as impurities comprises contacting the stream with an absorbing liquid; separating the purified stream and the absorbing liquid charged with CO2 and/or acidic gases; regenerating the absorbing liquid; and feeding to an absorption and/or extraction zone. The absorbing liquid is regenerated by releasing the pressure on the charged absorbing liquid to 1-2 bar, heating the partially regenerated absorbing liquid, and releasing the pressure of the partially regenerated absorbing liquid to 1-2 bar.
