Abstract

PURPOSE: To prevent the lowering of the desulfurizing and denitrating capacity of the absorbing liquid, by generating a soluble sulfite by carrying out the thermal decomposition treatment, etc. to the deposited (crystallized) substance which is obtained by contacting the exhaust gas containing SOx and NOx with the absorbing liquid containing, for example, Na2SO3 and EDTA iron chelate compound and then by circulating this soluble sulfite to the absorbing liquid.
