An electron beam radiation technology was adapted to remove SO2 and NOx simultaneously, which leaded to the production of an ammonium sulfate and an amonium nitrate in an existence of ammonia and water or ammonium hydroxide. Removal efficiencies of both SO2 and NOx were influenced by irradiated dose, inlet gaseous temperature and concentrations of water and ammonia (or ammonium hydroxide). The removal efficiency of SO2 and NOx could reach up to 95% at 10 - 20 kGy, when adding ammonia or ammoniun hydroxide with at least more than the stoichiometric ratio based on SO2 and NOx concentrations. In gas flow rates ranged from 2.5 to 20 liter/min, the removal efficiencies of SO2 and NOx showed nearly unchangeable values. The optimum reaction temperature were ranged from 90 to 100 ℃. |
