An experimental study on the simultaneous removal of NO and SO/sub 2/ 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 SO/sub 2/, the NO and SO/sub 2/ can be simultaneous removal. The gas phase NO is oxidized by corona discharge and converted into HNO/sub 3/ and HNO/sub 3/ 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 SO/sub 2/ and liquid phase oxidation of HSO/sub 3//sup -/ [S (IV)] to SO/sub 4//sup 2-/ [S (VI)] is promoted by corona discharge. Most of the SO/sub 2/ 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.
