Abstract

1. A process for removing CO2 and/or H2 S from a gas which contains CO2 and/or H2 S, in which the gas containing CO2 and/or H2 S is treated, in an absorption stage at from 40 to 100 degrees 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 CO2 and/or H2 S is taken off at the bottom of the absorption stage and then regenerated, and the regenerated absorption liquid is recycled to the absorption stage, characterized in that the regeneration is carried out exclusively in one or more flash stages, the flash gases being taken off at the top of the flash stage or flash stages, and, to compensate for the losses of water as a result of water present in the gas streams taken off at the top of the absorption stage and of the flash stage or flash stages, an amount of steam corresponding to the water loss is fed in at the bottom of the last flash stage or, if only one flash stage is used, at the bottom of this stage.
