摘要： The present invention provides a carbon dioxide recovery apparatus capable of recovering heat energy of carbon-dioxide-containing gas which includes an absorbing tower to generate and discharge a rich liquid absorbing carbon dioxide as carbon-dioxide-containing gas is introduced and contacted to an absorbing liquid to absorb carbon dioxide, carbon dioxide release devices to discharge semi-lean liquids which have steam containing a part of carbon dioxide released by heating the rich liquid discharged from the absorbing tower, and a regeneration tower to generate a lean liquid which has steam containing remaining carbon dioxide released and separated by heating the semi-lean liquids discharged from the carbon dioxide release devices and to return the lean liquid to the absorbing tower.
