CO2 RECOVERY APPARATUS AND CO2 RECOVERY METHOD

Japanese Patent JP2015151319

A

PROBLEM TO BE SOLVED: To provide a COrecovery apparatus and COrecovery method which are superior in an absorption rate of COand can achieve energy saving.SOLUTION: There is provided a COrecovery apparatus 1 that comprises : a COabsorption column 14 comprising an upper COabsorption unit 141B contacting waste gas 11C containing COwith COabsorbent 13 to make COabsorbent 13A, and a lower COabsorption unit 141A contacting the COabsorbent 13A with waste gas 11B containing COto make COabsorbent 13C; a COabsorbent regeneration column 15 heating the COabsorbent 13C to make the COabsorbent 13; a thermometer 102 measuring a temperature of the COabsorbent 13C supplied from the COabsorption column 14 to the COabsorbent regeneration column 15; and a control device 101 controlling a temperature of the COabsorbent 13B supplied to the lower COabsorption unit 141A based on the temperature of the COabsorbent 13C measured by the thermometer 102.
