Liquid amine scrubbing has been widely and intensively investigated at demonstration scale to capture CO2 at mass CO2 emission sources, such as thermal power plants and steelworks. However, CO2 regeneration process in a desorber is energy intensive, which limits implementation of this capture technology. Herein we propose an alternative CO2 capture method by electrodialysis. CO2 in a flue gas or blast furnace is trapped in aqueous K2CO3, and the resulting solution is condensed by electrodialysis. The trapped CO2 is finally recovered under vacuum. This technique can significantly reduce the required energy to capture CO2 in comparison to the current technology. Published by Elsevier Ltd.
