Reducing NOx and SOx pollutants in an industrial units using electron accelerator
Abstract
Electron beam accelerators technology has made significant progress in environmental applications in recent years. Including some environmental applications of industrial accelerators, is clearing the air from oxides of nitrogen and sulfur(NOx , SOx) produced by industrial facilities. Combustion of coal, oil, natural gas and other gases that are produced in power plant, refineries and industrial factories, produce high extent of these oxides wshich exceed the limit in most cases. Clearing by irradiation involves adding amounts of ammonia to output gases and irradiation by Electron beam accelerators. Irradiation produces radicals that interact again with NOx , SOx and produced the related gases. Due to the ammonia, these acids transform into ammonium sulfate ((NH4)2SO4 ) and ammonium nitrate (NH4NO3) are precipitated by electrostatic precipitators, and are used as chemical fertilizer. Cosidering purification process of pollutant gases by electron beam and the importance of electron accelerator in industrial plants that are polluting the environment in Iran, can be a suitable sollution for this environmental problem
