Abstract

PURPOSE: To recover high purity gypsum without requiring any special oxidation unit by maintaining the compsn. of exhaust gas and an absorbing soln. under specified conditions in removal of SOx in the exhaust gas by absorption is a wet exhaust gas desulfurization apparatus using a lime-gypsum method.
