Detoxification of trichloroethylene in a low-pressure surface wave plasma reactor

Article Abstract:

Chlorinated hydrocarbons such as trichloroethylenes are compounds present in toxic and hazardous wastes. Several methods for removing chlorinated hydrocarbon pollutants have been tested but they were costly and resulted in the formation of hazardous byproducts. Surface plasma wave reactions offer an alternative technology for the destruction and removal of trichloroethylenes. They involve the use of a low-pressure surface plasma wave reactor where trichloroethylene is reacted in water vapor and air. In comparison to other hazardous waste management methods, the use of surface plasma waves is cost-efficient and does not form hazardous byproducts.

Innovative surface wave plasma reactor technique for PFC abatement

Article Abstract:

The surface wave plasma reactor technique proves effective in destroying and removing perfluorocompounds (PFCs). The use of applied microwave powers from 500 to 2000 W, which corresponded to millisecond range residence times within the plasma, allowed the efficient removal of PFCs from semiconductor fabrication tools. Only a handful of compounds such as CO2, CO, COF2, H20 and HF are allowed to undergo hexafluoroethane conversion due to their low molecular weight gases.

Acetone conversion in a low-pressure oxygen surface wave plasma

Article Abstract:

The effectiveness of a low-pressure surface wave frequency oxygen plasma in destroying and removing acetone was investigated. In the process, an ultrasonic nebulizer was used to introduce acetone into a tubular reactor and the discharge was analyzed using on-line flame ionization gas chromatography. It is shown that a low-power, millisecond-range plasma can achieve near-100% conversion efficiency.
