Provided is a process for removing oxygen contained in a flue gas before the flue gas reaches an absorption tower so that the oxygen is not absorbed simultaneously when CO2 is absorbed by an amine-based absorbent at the absorption tower, so as to solve a CO2 absorbent degradation phenomenon. The apparatus for separating and collecting CO2 and the processing method, according to the present invention, remove dissolved oxygen in a flue gas through a catalyst combustion apparatus. Accordingly, dissolved oxygen is removed before the flue gas reaches the absorption tower, thereby preventing oxidative effect of an absorbent and solving the degradation phenomenon caused by the oxidative effect. |
