Abstract :
In this work, we report several approaches for the removal of SO 2 using nonthermal pulsed discharge plasma processing under absence of NH3. The gas-phase reaction was found to be less attractive due to its high energy cost. The increase in temperature decreased the SO2 removal rate, resulting in high energy cost. In case of the wet type plasma reactor, the discharge plasma greatly enhances the liquid phase oxidation of SO32- to SO42-. The presence of TiO2 catalyst increased the gas phase oxidation and the liquid phase oxidation as well
