Abstract

PURPOSE: To separate NNa(SO3)2Ca without depositing metal hydroxides and to recover the catalyst with a good efficiency, by maintaining pH value of the alkali treated solution from the solution containing NH(SO3)2 2 - after the absorption treatment of the exhaust gas containing SOx and NOx at the double alkali desulfurization and denitration treatment at an appropriate value
