Apparatus and methods for desulfurization and decarbonization of a process gas containing sulfur oxides and CO.sub.2. Ammonia may be used as a desulfurizing and decarbonizing agent. The gas may enter a desulfurization apparatus for desulfurization, and to produce an ammonium sulfate fertilizer. The desulfurized gas may enter a decarbonization apparatus to remove carbon dioxide in the gas, and to produce an ammonium bicarbonate fertilizer. The decarbonized gas may contain free ammonia. The decarbonized gas may be washed with a desulfurization circulating fluid and then with water. The washing fluid may be returned to the desulfurization apparatus for use as an absorbing agent for desulfurization. Acidic desulfurization circulating fluid may be used to wash ammonia, thereby achieving a high ammonia washing efficiency, and a low ammonia slip during the decarbonization process.
