摘要：
The present invention relates to a method of deacidizing a gaseous effluent, wherein the following stages are carried out: a) contacting the gaseous effluent with an absorbent solution so as to obtain a gaseous effluent depleted in acid compounds and an absorbent solution laden with acid compounds, the absorbent solution being selected for its property to form two separable phases when it absorbs an amount of acid compounds, b) separating the absorbent solution laden with acid compounds into two fractions: a first absorbent solution fraction depleted in acid compounds and a second absorbent solution fraction enriched in acid compounds, c) regenerating the second fraction so as to release part of the acid compounds, d) mixing a predetermined amount of water with the first absorbent solution fraction obtained in stage b) or with the regenerated absorbent solution fraction obtained in stage c), then e) recycling the first absorbent solution fraction and the regenerated absorbent solution as the absorbent solution.
