Wet FGD (flue gas desulfurization) systems are the most widely used technology for control of sulfur dioxide emissions from power plants. However, these systems are incapable of removing nitrogen oxides because most of the nitrogen oxides in flue gas is nitric oxide which is barely soluble in aqueous solutions. This paper addresses a new and cost-effective method for the generation of ozone to allow a wet scrubber system to remove SO{sub 2} and NO{sub x} simultaneously. In addition, a new method to suppress the formation of nitrogen-sulfur compounds in scrubbing liquors is discussed. The major oxidation product of yellow phosphorus is phosphoric acid mists which can be recovered for byproducts credit. The size of mists and the concentration of phosphoric acid in the mists were measured in order to determine an appropriate device for acid collection and concentration. An economic projection of the PhoSNOX process has been performed.
