Abstract
In a process for deacidifying a fluid hydrocarbon stream which comprises carbon dioxide (CO) 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 (), the substantially purified fluid stream and the absorption liquid which is loaded with COand/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 (). To regenerate the absorption liquid, the loaded absorption liquid is first expanded in a first low-pressure expansion stage () to a pressure of from 1 to 2 bar (absolute). The partially regenerated absorption liquid is then heated in a heat exchanger () and then, in a second low-pressure expansion stage (), again expanded to a pressure of from 1 to 2 bar (absolute).
