DEACIDIFICATION PROCESS OF A GAS BY MEANS OF AN ABSORBING SOLUTION WITH THE DISCHARGE OF A GASEOUS EFFLUENT FROM THE LOADED ABSORBING SOLUTION AND WASHING OF THE EFFLUENT USING THE REGENERATED ABSORBING SOLUTION

摘要

The invention relates to a method for deacidizing a gas feed comprising acid compounds. The gas feed is contacted in C1 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 of forming two liquid phases when heated. A gaseous effluent is then released from the absorbent solution laden with acid compounds. At least part of the absorbent solution laden 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 in reactive compounds. The water-enriched liquid phase is used to wash the gaseous effluent released from the absorbent solution enriched in acid compounds in order to obtain a gaseous effluent depleted in reactive compounds.
