1. A method for post-combustion CO2 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 CO2-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.
