CO2capture with liquid amine scrubbing has received current acceptance; however, the energy intensive heating process in CO2recovery requires alternate effective CO2separation methods. Condensation of CO2-trapping solutions by electrodialysis and successive CO2recovery under reduced pressure would decrease the required energy in the CO2capture drastically. Energy calculations and basic experiments reveal that the required energy can be reduced to less than 2.0 GJ (t-CO2)-1, which is about a half of the energy required for aqueous monoethanolamine.
