This article gives an overview of existing and possible electron accelerator applications for environmental pollution control. Laboratory and pilot plant tests and industrial applications have illustrated the possibility of applying this technology for purification and treatment of gaseous, liquid, and solid wastes. Examples of ionizing radiation application to protect the environment and human health are discussed.

“…The positive results of the tests performed on laboratory and pilot installation in Poland [1][2][3][4][5][6][7][8][9][10][11][12] has lead to decision concerning design and construction of the industrial demonstration plant for electron beam flue gas treatment. Industrial demonstration facility for electron beam flue gas treatment was designed and installed in EPS Pomorzany in Szczecin.…”

Fossil fuel combustion leads to acidic pollutants, like SO 2 , NO x , HCl emission. Different control technologies are proposed however, the most popular method is combination of wet FGD (flue gas desulfurization) and SCR (selective catalytic reduction). First, using lime or limestone slurry leads to SO 2 capture, and gypsum is a product. The second process where ammonia is used as reagent and nitrogen oxides are reduced over catalyst surface to gaseous nitrogen removes NOx. New advanced method using electron accelerators for simultaneous SO 2 and NO x removal has been developed in Japan, the USA, Germany and Poland. Both pollutants are removed with high efficiency and byproduct can be applied as fertilizer. Two industrial plants have been already constructed. One in China and second in Poland, third one is under construction in Japan. Information on the Polish plant is presented in the paper. Plant has been constructed at Power Station Pomorzany, Szczecin (Dolna Odra Electropower Stations Group) and treats flue gases from two Benson boilers 60 MW e and 100 MW th each. Flow rate of the flue gas stream is equal to 270 000 Nm 3 /h. Four transformer accelerators, 700 keV electron energy and 260 kW beam power each were applied. With its 1.05 MW total beam power installed it is a biggest radiation facility over the world, nowadays. Description of the plant and results obtained has been presented in the paper.
