Abstract

See full text

A carbon dioxide recovery system includes an absorption tower in which carbon dioxide is absorbed into an absorbing solution then the absorbing solution is output to a regeneration tower in which carbon dioxide is released from the absorbing solution. The regeneration tower outputs the absorbing solution from which carbon dioxide has been released and an exhaust gas included released carbon dioxide and water vapor. In a condensing section the exhaust gas is separated into dioxide gas stream and a condensed water stream. In a mixing section the condensed water is mixed with an amine to a replenishment amine aqueous solution in which the amine is dissolved in the condensed water. In a replenishment section the absorbing solution is mixed with the replenishment amine aqueous solution.
