Abstract
The combustion fume flowing in through lineis decarbonated by contacting with a solvent in column C. The solvent laden with carbon dioxide is regenerated in zone R. The purified fume discharged through linecomprises part of the solvent. The method allows to extract the solvent contained in the purified fume. The purified fume is contacted in zone ZA with a non-aqueous ionic liquid of general formula QA; Qdesignates an ammonium, phosphonium and/or sulfonium cation, and Aan anion likely to form a liquid salt. The solvent-depleted purified fume is discharged through line. The solvent-laden ionic liquid is regenerated by heating in evaporation device DE. The solvent separated from the ionic liquid in device DE is recycled.
