Abstract
Procedure for the regeneration of regenerable aqueous purification solutions, which are used for the mass elimination of acid gases, by absorption from gas mixtures containing said acid gases, in a cyclical process in which said aqueous purification solutions are regenerated in a regeneration system by steam extraction before recycling to the absorption stage, a part of the purification solutions being regenerated in a main regeneration section of the regeneration system, while the other part of the purification solutions are regenerated in a regeneration auxiliary section of the regeneration system, characterized in that the pressure in the regeneration auxiliary section is chosen irrespective of the pressure of the main regeneration section and at least a part of the extraction steam required in the regeneration auxiliary section it is obtained by evaporation of the dep solution In a reduced pressure zone connected to the suction side of a steam jet thermocompressor, the mixture of the motor steam from the thermocompressor and evaporated steam recompressed in said auxiliary regeneration section is directly discharged.
