Abstract: This invention describes a stand-alone ozone generator and method to generate high quantities of ozone which can be injected in a multitude of applications where great quantities are needed at a low production cost. This generator can be useful for flue gas oxidation, water purification, HVAC air purification, and any other commercial or industrial process where ozone is needed to oxidize organic or inorganic species. The process relies on the reaction of air or oxygen with a solution of white or yellow phosphorus contained in a reactor. In this method, the ozone generated is purified in-Situ and can be directly used in any process. The elemental phosphorus and the phosphorus derivatives are enclosed in the ozone generator and are not allowed to escape. The process can pay for itself by the sales of the phosphorus derivatives generated through the reaction.

Abstract: A system and method for the reduction of NO.sub.x in a flue gas are disclosed. A P.sub.4 in water liquid/liquid emulsion is injected into a flue gas having a temperature of about 180.degree. C. to about 280.degree. C. to induce phosphorus-accelerated oxidation of the NO in the flue gas. NO.sub.2 and phosphorus oxides are subsequently removed from the flue gas stream at a location sufficiently downstream of the injection site that the oxidation of NO in the flue gas is substantially complete prior to the removal of NO.sub.2. This significantly improves the NO.sub.x recovery rate of the present system and method over those of the prior art. The system can be retrofitted to the waste gas stream of any stationary combustion source regardless of the fuel burned. The system is advantageously used in connection with a wet scrubber for the removal of NO.sub.2 and other water soluble flue gas components.
