Electron beam gaseous pollutants treatment

Summary form only given, as follows. High energy electrons create thousands of ions and free radicals along their path. In consequence radiolytical processes take place that with usage of additional reactants at proper physical gas conditions may lead to new air pollution control technologies. Three examples are discussed: SO/sub 2/ and NO/sub x/ removal (combustion flue gases); volatile organic compounds removal (industrial off-gases and vapor from ground water stripping); SO/sub 2/ high concentration flue gas treatment (copper industry off-gases). The experimental tests, depending on the subject has been performed at two different units. One is an industrial pilot plant constructed in an electropower station on a coal fired boiler, with gas flow up to 20,000 cNmph, equipped in two electron accelerators, 50 kW power and 800 keV each. The second is a laboratory installation with the flow up to 400 cNmph, in this case flue gases are produced by two gas fired boilers and research setup is furnished in an accelerator of 20 kW beam power and electrons energy up to 2 MeV. The results of the tests performed at laboratory and industrial pilot plant are discussed. On this basis technical and economical evaluation of full size industrial installation has been prepared.
