Abstract: In a process for deacidifying a fluid hydrocarbon stream which comprises carbon dioxide (CO 2 ) and/or other acid gases as impurities, the fluid stream is brought into intimate contact with an absorption liquid in an absorption or extraction zone ( 12 ), the substantially purified fluid stream and the absorption liquid which is loaded with CO 2 and/or other acid gases are separated from one another, and the absorption liquid is subsequently regenerated and then again fed to the absorption extraction zone ( 12 ). To regenerate the absorption liquid, the loaded absorption liquid is first expanded in a first low-pressure expansion stage ( 22 ) to a pressure of from 1 to 2 bar (absolute). The partially regenerated absorption liquid is then heated in a heat exchanger ( 20 ) and then, in a second low-pressure expansion stage ( 29 ), again expanded to a pressure of from 1 to 2 bar (absolute).

Abstract: 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.
