Abstract
In a method for removing acid gases from hydrocarbon-comprising fluids, (a) a carbon dioxide-rich acid gas stream is separated off from the fluid by scrubbing with a liquid absorbent, (b) the fluid is contacted with a solid adsorbent for removing sulfur-comprising acid gases, and (c) the loaded solid adsorbent is regenerated by contacting with at least one purge gas under regeneration conditions. A carbon dioxide-rich acid gas stream separated off in step (a) is used as purge gas.
