【Abstract】 Several simultaneous desulfurization and denitrification technologies were introduced and analyzed. It includes two high-energy electronic activation and oxidization such as the electron beam with ammonia and pulsed corona with ammonia, and three solid phase absorbent/regenerate techniques such as activated carbon adsorption with ammonia, NOXSO technique and CuO method. The basic principles and process flow of SNOX, SNRB craft gas/solid catalyst and wet simultaneous desulfurization and denitrification technologies were discussed. Based on specific industrial application and update development, the process characteristics, advantages and disadvantages were analyzed in detail. Compared with the single desulfurization or denitrification technology, the above mentioned simultaneous technologies is of simpler process, limited coverage, less investment and production cost. With the increasingly strict requirements for SO2 and NOx emission, the integrated desulfurization and denitrification technology takes on prospective development in the future.更多还原
