Abstract
An object of the present invention is to provide a method for treating an exhaust gas containing CO, that can adjust the concentration of an oxidation inhibitor in an absorbent to the concentration enough to inhibit oxidation, without measuring the concentration of the oxidation inhibitor in an alkanolamine contained in a COabsorbent. Disclosed are a method and a device for adjusting the compositional ratio of an absorbent, in which absorption and release of carbon dioxide are performed by adding an oxidation inhibitor to an alkanolamine absorbent when the sum of the concentrations of ammonia and an alkylamine in an absorber column outlet gas of a COabsorption equipment.
