Abstract
A COrecovery apparatus includes: an absorption tower configured to remove COin an exhaust gas by contacting with a COabsorption liquid containing an absorption agent; a regeneration tower for regenerating the COabsorption liquid from the absorption tower; a reflux water drum for separating COgas released from the regeneration tower into COgas and condensed water; a first cleaning device installed in a gas-phase part of the regeneration tower and configured to remove the absorption agent contained in the COgas flowing through the gas-phase part, by using a first cleaning liquid containing at least the condensed water from the reflux water drum or a water obtained from the condensed water; and a control device configured to adjust a supply amount of the first cleaning liquid to the first cleaning device so that a concentration of the absorption agent in the condensed water is maintained to be not greater than a predetermined value.
