In the past twenty-five years, researchers havediscussed the use of radiation and non-thermal plasmatechniques to reduce SO_2, NO_x and N_2O emissions fromflue gas exhausts. The use of electron beam technology forprocessing of flue gas exhaust streams is often the mostpromising of such techniques. A process based on thistechnology uses fast electrons to promote radical formation,which results in the formation of nitric and sulfuric acids as anaerosol within the flue gas. Ammonia is injected prior toirradiation, and will react with the acid aerosols to form solidammonium nitrate and ammonium sulfate. The particulates arecaptured downstream and recovered, and can be sold asfertilizer. This paper documents the critical literature reviewcompleted, as well as summarizes the current status of theexperimental design and setup at Pennsylvania State University.
