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.
