ABSTRACT:
The combustion fume flowing in through line1is decarbonated by contacting with a solvent in column C2. The solvent laden with carbon dioxide is regenerated in zone R. The purified fume discharged through line9comprises 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 Q+A−; Q+designates an ammonium, phosphonium and/or sulfonium cation, and A−an anion likely to form a liquid salt. The solvent-depleted purified fume is discharged through line17. 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.
