    摘要： A process for removing carbon dioxide from a fluid comprises the steps of: (a) treating the fluid by bringing it into countercurrent contact with a liquid absorbent in a first absorption zone and thereafter in a second absorption zone to absorb at least part of the carbon dioxide contained in the fluid into the absorbent; (b) depressurizing the loaded absorbent to release a first stream of carbon dioxide and yield a partially regenerated absorbent; (c) recycling a first stream of the partially regenerated absorbent into the first absorption zone; (d) heating a second stream of the partially regenerated absorbent to release a second stream of carbon dioxide and yield a regenerated absorbent; (e) recycling the regenerated absorbent into the second absorption zone; (f) condensing water vapour entrained in the second stream of carbon dioxide by cooling the second stream of carbon dioxide and transferring at least part of the heat recovered to the partially regenerated absorbent by indirect heat exchange. The invention provides a two-stage carbon dioxide recovery process wherein the overall energy required for carbon dioxide recovery is reduced and/or wherein at least part of the carbon dioxide is recovered at a pressure higher than atmospheric pressure so as to reduce the energy required for compression of the carbon dioxide, e.g., for sequestration. Also disclosed is a plant for removing carbon dioxide from a fluid.

    摘要： A method for obtaining an acid gas stream having a pressure of from 3 to 30 bar by removal of acid gases from a fluid stream containing H2S, the molar fraction of H2S based on the total amount of acid gases being at least 50 mol %, the method comprising bringing the fluid stream into intimate contact with a liquid absorption medium, thus producing a fluid stream substantially freed from acid gases and an acid-gas-loaded liquid absorption medium; separating the fluid stream and the liquid absorption medium; separating, by heating and optionally by expansion or stripping, the liquid absorption medium into an acid gas stream and a regenerated liquid absorption medium; passing the regenerated liquid absorption medium into a heat exchanger and cooling it there by using part of its thermal energy to heat up the acid-gas-loaded liquid absorption medium; and recirculating the regenerated liquid absorption medium.
