ABSTRACT:
The improved method for treating waste gases by exposure to electron beams which comprises adding ammonia to a waste gas containing sulfur oxide (SO.sub.x) and/or nitrogen oxides (NO.sub.x) and thereafter exposing the gas to an electron beam so as to remove the sulfur oxides and/or nitrogen oxides therefrom is characterized by first mixing ammonia gas uniformly with air, then forming a homogeneous gas-liquid mixture from said gaseous mixture and water, and spraying said homogeneous mixture into a reactor. Efficient desulfurization can be realized even if the temperature of the waste gas being treated is fairly high at the exit of the reactor and the concentration of ammonium sulfamate in the by-product ammonium sulfate can be reduced.
