Patent ID: 6905577

Claim:
A method for the oxidation of volatile organic compounds contained in gaseous effluents, comprising: a) providing an electrical corona discharge reactor for producing ozone; b) supplying an electric current to said reactor in order to generate corona discharge; c) passing the gaseous effluents upstream of the corona discharge reactor through a condenser in order to reduce the amount of water contained in said gaseous effluents and through a filter in order to remove solid particles also contained in said gaseous effluents before said gaseous effluents are passed through said reactor; d) then passing the gaseous effluents through said corona discharge reactor in order to oxidize the volatile organic compounds contained in the gaseous effluents by the ozone generated in; e) causing the gaseous effluents also to contact a metal catalyst in order to further oxidize volatile organic compounds contained in said gaseous effluents; and f) subjecting the gaseous effluents also to UV radiation in order to further oxidize volatile organic compounds contained in said gaseous effluents.
