Process for removing acid gases from a fluid stream, in which the fluid stream is passed through a first absorption zone in contact with an absorption medium in the form of an aqueous amine solution in an absorber and through a second absorption zone, the loaded absorption medium is passed into a first regeneration zone, a part of the resultant partially regenerated absorption medium is passed into the first absorption zone, the other part of the partially regenerated absorption medium is passed into a second regeneration zone and a part of the resultant regenerated absorption medium is passed into the first absorption zone and the other part of the regenerated absorption medium into the second absorption zone. The process can be carried out on a hotpot plant with minor changes in apparatus, with the energy requirement for the same performance being no higher than with the hotpot process. |
