Coaxial Pulsed Corona Reactor for Treatment of Hazardous Gases
Abstract
The destruction of hazardous gaseous chemicals has in the past been effectively accomplished using thermal techniques. Pulsed corona reactors are promising candidates for more efficient destruction of hazardous gases using a non-thermal electrical discharge at atmospheric pressure. The energy required for chemical destruction is deposited in the medium by highly energetic electrons present near the streamer head while direct heating of the neutral gas molecules is avoided. The current work emphasizes the construction of an electrically efficient, low cost pulsed corona reactor capable of treating a flow rate of 4 liters/minute. Determining optimum pulse parameters for the discharge and scaling the device to higher flow rates will be the primary focus of future work, with specific emphasis being placed on the use of fast-rising pulses (nanoseconds) of limited pulse-width (10's to 100's of nanoseconds). A testbed for chemical analysis has also been assembled and preliminary results include the electrical efficiency of the device and the chemical destruction efficiency when challenged by small concentrations of hazardous gases in ambient air.
