Abstract

Provided are a system for processing exhaust gas and a method for processing exhaust gas whereby operating cost and volume of wastewater are significantly reduced and the supplied amount of an NO reducing agent and a mercury oxidizing agent can be controlled. In the system for processing exhaust gas according to the present invention an aqueous solution including an ammonium halide is sprayed into a flue NO is reduced in a denitrification unit and mercury is oxidized and SO and mercury are removed in a desulfurization unit. In the system for processing exhaust gas ammonium sulfate and/or ammonium carbonate is added to wastewater from which CaSO has been separated the wastewater having been discharged from the desulfurization unit and an ammonium halide is generated. The wastewater including the ammonium halide is sprayed as the aqueous solution.
