Abstract: A carbon dioxide capturing apparatus and process uses a self-generating power means that uses carbon dioxide in combustion exhaust gas through the convergence of a carbon dioxide absorption tower. The capturing apparatus and process also relies on ionic generator associated technology using a concentration difference between seawater and freshwater. The capturing apparatus and process result in increased production efficiency for electric energy and reduced costs for a carbon dioxide capturing process by increasing a concentration difference using an absorbent liquid for absorbing carbon dioxide and, at the same time, electricity is obtained through carbon dioxide which is a greenhouse gas.

Abstract: An apparatus and process are provided for electricity production and high-efficiency trapping of carbon dioxide, using carbon dioxide within combustion exhaust gas and converging technologies associated with a carbon dioxide absorption tower and a generating device using ions which uses a difference in concentration of salinity between seawater and freshwater. It is expected that enhanced electrical energy production efficiency, an effect of reducing costs for the operation of a carbon dioxide trapping process, and electricity production from carbon dioxide, which is a greenhouse gas, can be simultaneously achieved by increasing the difference in concentration using an absorbent for absorbing carbon dioxide.
