Abstract
A method and apparatus for photothermal detoxification of toxic organic compounds are provided. The apparatus comprises a means for maintaining the gas stream from the targeted source at a temperature of greater than 200.degree. C., an optional air pollution control device, a radiation source which emits radiation at a wavelength of less than 320 nm and an outlet for releasing the nontoxic reaction products to the atmosphere.
Claims13
A photothermal process for the detoxification of chlorinated aromatic hydrocarbons contained in a gas stream comprising the steps of:
- heating chlorinated aromatic hydrocarbons to a temperature of greater than 200.degree. C. to form a gas stream or maintaining a pre-existing chlorinated aromatic hydrocarbon containing gas stream produced from a combustion source at a temperature of greater than 200.degree. C.;
- exposing said gas stream to radiation at a wavelength of less than 280 nm for at least one second to convert said chlorinated aromatic hydrocarbons in said gas stream to nontoxic reaction products, and releasing said gas stream to the atmosphere.
