More Information
Summary:The invention is a method for deacidizing a gaseous effluent comprising acid compounds, such as CO2 and/or H2S, and a device for implementing the method, through contact with a demixing absorbent solution. Regeneration is performed by vapor injection into the liquid guard (202) formed by the regenerated absorbent solution in the bottom of regeneration column (G). The vapor is generated within a reboiler (203) from a fraction of the regenerated absorbent solution withdrawn from the regeneration column. Vapor injection enables convective movement of the liquid for preventing any decantation phenomenon in the bottom of the regeneration column bottom which is harmful to the smooth operation of the deacidizing process.
