Abstract :
An experimental study on the simultaneous removal of NO and SO2 in a simulated flue gas has been carried out using multipoint to water corona discharge reactor. In a simulate flue gas containing of 400 ppm NO and 400 ppm SO2, the NO and SO2 can be simultaneous removal. The gas phase NO is oxidized by corona discharge and converted into HNO3 and HNO3 dissolve velocity constant is very high, so that it is possible to remove by liquid phase absorption. The absorption into the water of gas phase SO2 and liquid phase oxidation of HSO3- [S (IV)] to SO42- [S (VI)] is promoted by corona discharge. Most of the SO2 removal is attributed to the liquid phase absorption and NO conversion via gas phase oxide. In a word, the corona discharge increases the mass transfer and oxidation.
