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. According to the invention, the absorbent solution is regenerated in at least two stages in regeneration zones Zand Z. At the end of the first regeneration stage in Z, at least part of the partly regenerated absorbent solution is separated into two fractions in B: a fraction rich in acid compounds and a fraction depleted in acid compounds. Fractionrich in acid compounds is sent to the second regeneration stage in Z. The fraction depleted in acid compounds and regenerated absorbent solutionfrom the second regeneration stage are recycled to absorption column C The method can be applied to combustion fumes decarbonation and to natural gas or synthesis gas deacidizing.
