ABSTRACT:
Ozone and, if necessary, water is added to an exhaust gas, such as air, containing hydrogen- and carbon-containing molecules of a pollutant. The exhaust gas is then continually flowed into one or more oxidizing reaction chamber modules. In the reaction chamber(s) the ozone- and water-containing gas is subjected to intense ultraviolet radiation (wavelength of 254 nm) to promote the formation of hydroxyl radicals to oxidize the pollutant molecules to carbon dioxide and water. The continually discharged gas is analyzed for residual ozone and hydrocarbon content and the analytical data used in feedback control of ozone addition and UV radiation intensity.
