Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A carbon dioxide recovery apparatus, comprising: an absorbing tower in which a carbon-dioxide-containing gas is introduced and contacted with an absorbing liquid that absorbs carbon dioxide, the absorbing liquid having carbon dioxide from the carbon-dioxide-containing gas absorbed therein being discharged from the absorbing tower as a rich liquid; a carbon dioxide release device in which the rich liquid discharged from the absorbing tower is introduc…
