Experimental assessment of pulsed corona discharge for treatment of VOC emissions
The application of the pulsed corona discharge was experimentally evaluated for the treatment of VOC mixtures typically present in the exhaust streams of wood processing industry. Methanol, acetone, dimethyl sulfide, and alpha-pinene were selected as representative VOC compounds. An experimental database for the destruction and removal efficiencies and energy costs was produced for individual VOCs and their mixtures valid for input concentrations (5 to 1000 ppm), temperatures (25 to 200degreesC) and relative humidity (0 to 100%). High removal efficiencies and destruction rates above 99% were obtained with power levels competitive with the present technologies for VOC removal. Energy cost of VOC removal increases in the species sequence: dimethyl sulfide, methanol, alpha-pinene, acetone. It was found that energy decomposition costs were reduced as temperature and moderate humidity increased.
