Simultaneous Removal of SO2 and NO by O3 Oxidation Combined with Seawater as Absorbent

Aiming at NOx (NO 90%, NO2 10%) and SO2 in simulated vessel emissions, denitration desulfurization were studied through ozone oxidation combined with seawater as absorbent. Specifically, the different influencing factors of analyzed. The results indicated that efficiency NO can reach over 90% when molar ratio O3/NO is 1.2. Ozone washing same unit decrease temperature NO, avoid high decomposition, enhance NO. When inlet initial concentration lower than 800 ppm, removal be improved by increasing concentration, greater would efficiency. Increasing has minor effect on desulfurization, but slightly reduces absorption due to competition solution. Besides, final products (NO2?, NO3?, SO32?, SO42?) analyzed ion chromatography.
