Abstract
A contaminant-tolerant hybrid scrubbing solvent is provided for post-combustion CO2 capture and removal, the scrubbing solvent including an amine and a low fraction of ammonia. A stripping carrier having a low latent energy is included for solvent regeneration. In one embodiment, the amine is MEA and the stripping chemical having low latent energy is pentane or an isomer thereof. Processes and apparatus for CO2 removal from post-combustion gases and for solvent regeneration are described.
