REACTIVE EXTRACTION PROCESS FOR REGENERATION OF AMINE-BASED SOLVENTS USED FOR CARBON DIOXIDE CAPTURE |
摘要 |
<p>A method for recovery of impurities and/or degradation products and/or heat-stable salts from amine-based solvents used for capture of CO2 from gas streams. The method comprises recovering CO2 from a CO2-enriched amine-based solvent thereby producing a lean amine-based solvent, contacting and mixing together the lean amine-based solvent with a reaction composition comprising a phase-change catalyst and a diluent, thereby producing a first organic phase comprising the impurities and/or degradation products and/or heat-stable salts and a first aqueous phase comprising the lean amine-based solvent, separating the first organic phase and the first aqueous phase; and separately recovering the first organic phase and the first aqueous phase. The organic phase can be regenerated by intermixing with a NaOH solution to form an organic phase comprising therein the reaction composition and and an aqueous phase comprising the NaOH solution with the impurities and/or degradation products and/or heat-stable salts.</p> |
