<p>Disclosed is a method for post-combustion carbon dioxide capture comprising: (I) introducing an aqueous solution containing an amine-based absorption compound to an absorber, the absorber being located downstream of a flue gas scrubber; (II) delivering a carbon dioxide containing gas from the flue gas scrubber to the absorber to form a CO2-laden amine-based absorption compound; and (III) subjecting the CO2-laden amine-based absorption compound to a regeneration step for regenerating the CO2-laden amine-based absorption compound and stripping out CO2 from the CO2-laden amine-based absorption compound, wherein energy is supplied to a stripper to accomplish the regeneration step, wherein the amine-based absorption compound is a combination of 2-(2-hydroxyethyl)-piperidine and one or more amine-based promoter compounds selected from monoethanolamine, piperazine, 2-(1-piperazinyl)-ethylamine, 1-methylpiperazine, 2-methylpiperazine, 3-methylaminopropyl-amine, morpholine, piperidine, or suitable combinations of any two or more thereof.</p> |
