A pulsed corona reactor PCR has been investigated for the abatement of a variety of hazardous gaseous compounds including volatile organic compounds, chlorofluorocarbons, perflourinated compounds and oxides of nitrogen. In this technique, a series of fast risetime, high-voltage pulses are applied to a wire-cylinder geometry resulting in a plethora of streamer discharges within an atmospheric pressure flowing gas volume. This non-thermal plasma can be particularly effective in treating dilute concentrations of pollutant compounds where power consumption is of prime concern. Such conditions exist in a variety of situations including chemical warfare threat scenarios, semiconductor processing, and mobile sources. In order to assess the value of such a technology as a solution to practical applications, a complete analysis of reactor operation must be performed, including wall-plug efficiency and by-product identification.
