CO2 RECOVERING APPARATUS

摘要

A CO 2 recovering apparatus includes a CO 2 absorber (16) that brings flue gas containing CO 2 and O 2 into contact with CO 2 absorbing liquid to reduce CO 2 in the flue gas; and a regenerator (18) that reduces CO 2 in CO 2 absorbing liquid (rich solvent) that has absorbed CO 2 in the CO 2 absorber (16) to regenerate the CO 2 absorbing liquid, so that the regenerated CO 2 absorbing liquid (lean solvent) having CO 2 reduced in the regenerator (18) is reused in the CO 2 absorber (16). A lower liquid reservoir (50) is located at the bottom of the CO 2 absorber (16), and an air-bubble gathering member (51) is arranged therein to gather air bubbles included in the absorbing liquid.
