METHOD FOR DEACIDIFYING A GAS USING AN ABSORBENT SOLUTION, WITH RELEASE OF A GASEOUS EFFLUENT FROM THE ABSORBENT SOLUTION AND WASHING OF SAID EFFLUENT WITH THE REGENERATED ABSORBENT SOLUTION

摘要

The invention relates to a method for deacidifying a gaseous load comprising acid compounds. The gaseous load is brought into contact in C1 with an absorbent solution in such a way as to obtain a gaseous effluent depleted in acid compounds and an absorbent solution loaded with acid compounds, the absorbent solution being selected for its characteristic of forming two liquid phases when heated. Then, a gaseous effluent is released from the absorbent solution loaded with acid compounds. At least part of the absorbent solution loaded with acid compounds is thermally regenerated and at least a fraction of the regenerated absorbent solution is separated into a water-enriched liquid phase and a liquid phase enriched with reactive compounds. The water-enriched liquid phase is used to wash the gaseous effluent released from the absorbent solution enriched with acid compounds in order to obtain a gaseous effluent depleted in reactive compounds.
