摘要：
The gaseous effluent to be treated is contacted in C1 with an absorbent solution selected for its property of forming two separable phases when it has absorbed an amount of acid compounds and when it is heated. The absorbent solution laden with acid compounds is then heated in E1 and E3 so as to separate two fractions in BS1: a first absorbent solution fraction depleted in acid compounds and a second absorbent solution fraction enriched in acid compounds. The second fraction is regenerated in C2 so as to release part of the acid compounds, and the first absorbent solution fraction and the regenerated absorbent solution are recycled as absorbent solution.According to the invention, an absorbent solution portion circulating in C1 is cooled in E2 in order to prevent demixing of the solution in column C1.
