<p>An apparatus and a method for recovering CO 2 are provided in which an energy efficiency is improved. The apparatus for recovering CO 2 includes a flow path (6, 16, 26) for returning extracted, temperature risen semi-lean solution into a regeneration tower (1008) wherein at least a part of the semi-lean solution obtained by removing a partial CO 2 from a rich solution (1007) infused in a regeneration tower from an upper part of the regeneration tower (1008) is extracted, raised its temperature by heat exchanging with a high-temperature waste gas in a gas duct (1001a) of an industrial facility such as a boiler (1001), and then returned into the regeneration tower (1008).</p> |
