| 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 101 to generate and discharge a rich liquid 301 absorbing carbon dioxide as carbon-dioxide-containing gas 111 is introduced and contacted to an absorbing liquid to absorb carbon dioxide, carbon dioxide release devices 103, 104 to discharge semi-lean liquids 320, 306 which have steam containing a part of carbon dioxide released by heating the rich liquid 301 discharged from the absorbing tower 101, and a regeneration tower 102A to generate a lean liquid 316 which has steam containing remaining carbon dioxide released and separated by heating the semi-lean liquids 320, 306 discharged from the carbon dioxide release devices 103, 104 and to return the lean liquid 316 to the absorbing tower 101. |
