A method for removing contaminants from contaminated effluent

摘要

The present invention provides a method of removing a contaminant, e.g. CO2 and/or H2S, from a contaminated stream (10). The contaminated stream (10) is contacted in an absorber (2) with an absorbent solution (80), thereby obtaining a contaminant-depleted stream (20) and a contaminant-enriched absorbent stream (30). The contaminant-enriched absorbent stream (30) is separated in a regenerator (3), thereby obtaining a contaminant- depleted absorbent stream (60) at a bottom of the regenerator (3), and a contaminant-enriched stream (50). The contaminant-depleted absorbent stream (60) forms a lower layer of a first liquid phase (A) and a higher layer of a second liquid phase (B). The first liquid phase (A) and the second liquid phase (B) are removed simultaneously at the interface (X) of these liquid phases. The contaminant-depleted absorbent stream (60) is reused.
