ABSTRACT:
A combination spray drying and electron beam treatment for effluent gases provides air pollution control for even high sulfur coals.
Liquid and a reagent are injected into the effluent gas in the spray dryer, thereby cleansing the effluent gas, decreasing its temperature, and increasing its moisture content. The spray drying decreases the temperature at least to below 100.degree. C. and, most preferably, to between 60.degree. C. and 70.degree. C. The decreased temperature, increased moisture content effluent gas including both reacted compounds and unreacted reagent is conveyed into an irradiation chamber, whereat radiation causes the gaseous sulfur oxides and/or nitrogen oxides to convert into mist and/or solid particles. The unreacted reagent may then react with the acid mist. The effluent gases are then subjected to dry particular collection.
