AbstractVolatile organic compounds (VOC) containing gases from semiconductor industries are toxic to human health, and, therefore, need to be controlled. A bench scale wire-pipe type pulsed corona discharge induced plasma reactor was used to decompose these compounds from dry air. The concentration of VOCs and by-products are measured by both gas/chromatography and Fourier Transform InfraRed Spectroscopy systems. The removal efficiencies for both xylene and trichloroethylene depends on the residence time and applied voltage and a 100% removal efficiency was achieved for both 200 ppm o-xylene and TCE with the residence time below 2.5 s and applied voltage of 25 kV. When xylene and TCE mixture was used, xylene removal is enhanced while TCE removal is reduced. The mechanism of destruction process and discharge by-products are also discussed in detail.

AbstractExperiments on the plasma-assisted oxidation of dilute concentrations of acetone, benzene, and ethylene in atmospheric pressure gas streams by pulsed corona electrical discharge processing show that temperature influences the oxidation chemistry. In dry air mixtures, the main oxidation products are CO and CO
