·
OSTI ID:6148088
A process is provided for treating exhaust gases to remove sulfur dioxide by contacting the gas with a solution of ammonium sulfite and bisulfite in a scrubber. A portion of the solution discharged from the scrubber is oxidized to form ammonium sulfate and the treated gas is further treated with the oxidized solution.
