摘要：A process for simultaneous desulfurization and denitrification is proposed, consisting of ozone as the oxidizing agent for NO and ammonia solution as the absorbent. The results showed that the presence of SO2 and the concentration changes of NO and SO2 have little impact on the oxidation of NO, the oxidation efficiency of NO can achieve over 90% when the molar ratio of O-3/NO is 1.0. The presence of NOx had little effect on the absorption of SO2, while an appropriate increase of SO2 concentration favorably affected NOx absorption. The removal efficiency of SO2 and NO reached 99.34 and 90.01% at pH 10, flow rate 0.95 Nm(3)/h, n[O3]//n[NO] 1.0, initial SO2 concentration 2000 mg/Nm(3), initial NO concentration 200 mg/Nm 3, ammonia concentration 0.3%, oxygen content of the simulated flue gas 12%, oxidation reaction temperature 423 K and absorption reaction temperature 298 K in the experimental system.
