Abstract
A COrecovery device includes a cooling tower including a cooling unit for bringing the flue gas, which contains CO, into contact with water so as to cool flue gas; a CO-absorbing unit for bringing the flue gas into contact with a COabsorbent (lean solution) so as to remove COfrom flue gas; and a regenerator including an absorbent regenerating unit for releasing COfrom a rich solution so as to regenerate the COabsorbent. The CO-absorbing unit includes: a cocurrent flow CO-absorbing unit provided in a cocurrent flow COabsorber, for bringing the flue gas into contact with the COabsorbent in a cocurrent flow so as to remove COfrom flue gas and a countercurrent CO-absorbing unit provided in a COabsorber, for bringing the flue gas into contact with the COabsorbent in a countercurrent flow so as to remove COfrom flue gas.
