The present invention relates to both a method and a device for removin g Volatile Organic Compounds (VOC) from gaseous streams in conduits chimneys and/or exhaust ducts. The method is especially useful in eliminating a large variety of pollutants, and especially organic odorous pollutants such as mercaptans and sulfurous compounds. The method is based on the principle of direct oxidation of the pollutants by ozone and th e conversion of these pollutants into non-harmful products, and comprises the steps of: a) providing an electrical corona discharge reactor capable of producing ozone; b) supplying an electric current to the corona discharge reactor; and c) causing the gaseous effluents to flow through the reactor. With this method, the volatile organic compounds contained in the gaseo us effluents are oxidised by the ozone produced by the corona discharge reactor. The present invention also relates to a device for reducing this method into practice, this device being a corona discharge reactor comprising two concentric electrodes producing ozone. |
