<p>C02 and/or H2S are removed from gases which contain C02 and/or H2S by means of an aqueous absorption liquid containing an alkanolamine, by a process wherein the said gas is treated, in an absorption stage, at from 40 to 100.degree.C, with an aqueous absorption liquid containing from 20 to 70% by weight of methyldiethanolamine, the treated gas is taken off at the top of the absorption stage, the aqueous absorption liquid laden with C02 and/or H2S is taken off at the bottom of this stage and is regenerated by being let down in two or more flash stages, and the final flash stage is operated under reduced pressure and the regenerated absorption liquid is recycled to the absorption stage.</p> |
