CO2 RECOVERY DEVICE AND CO2 RECOVERY METHOD

摘要

A CO2 recovery device (10) comprises a CO2 absorption tower (13) for bringing an exhaust gas (11) containing CO2 into contact with a CO2 absorbing liquid (12) and removing the CO2 contained in the exhaust gas (11), a regenerating tower (15) for carrying out regeneration by removing the CO2 from the absorbing liquid (rich solution) (14) that has absorbed CO2 in the CO2 absorption tower (13), and a degassing unit (42), which is a CO2 recovery device that allows for the absorbing liquid (lean solution) that has been regenerated by removing the CO2 in the regenerating tower (15) to be reused in the CO2 absorption tower (13) and which is for removing the gas bubbles taken into the CO2 absorption tower to a rich solution feed tube (41) for feeding the rich solution (14) from the CO2 absorption tower (13) to the regenerating tower (15).
