Abstract
The gaseous effluent to be treated is contacted in Cwith 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 Eand Eso as to separate two fractions in BS: 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 Cso 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 Cis cooled in Ein order to prevent demixing of the solution in column C
