Abstract In Korea, 343,161 tons of SOx were emitted in 2014. SOx itself cause various health effects. Besides, fine particles are generated from such gas precursors. For SOx removal, a lot of methods such as scrubber technology and etc. were used. Pulsed plasma is one of the above methods by converting SO2 gas to (NH4)2SO4 particles using pulsed plasma and NH3 gas. Converted particles can be removed by water-flowing film inside the reactor. SO2 was controlled by voltage of the pulse power, NH3 concentration. The gas concentration was measured NDIR measurement equipment and FTIR equipment. Air was supplied to the reaction chamber with 30 m3/h. Pulsed plasma reaction generated 30~100 nm particles. Gas concentration after this reaction was decreased to lower than 2 ppm. This research can be applied to the reduction facility of SOx emitting factories. This research was supported by the Eco-Innovation Project operated by the Korea Ministry of the Environment.
