N2 - Process design and cost estimation were conducted for CO 2 recovery by liquid absorption with alkaline solution, coupled with bipolar membrane electrodialysis for CO 2 gas separation and alkaline solution regeneration. The electrodialysis performances and power consumption for CO 2 recovery and alkaline solution regeneration were examined using laboratory-scale electrodialysis equipment under various conditions; degree of CO 2 absorption, CO 2 recovery ratio, alkaline concentration, and type of cation exchange membrane. The total cost of CO 2 recovery was estimated for the treatment of CO 2 emitted from a 400 MW coal-fired thermal power plant. The minimum cost for the optimum condition was about US$180 per ton-CO 2 removed, which is higher than that for the conventional process using amine absorption and thermal desorption. However, a sensitivity analysis indicates that the overall cost could be significantly reduced if the cost of membranes was reduced.
