Advanced combustion and oxidation techniques for the destruction of hazardous wastes
Silent discharge plasmas (SDP) have been demonstrated in the laboratory to be effective in destroying hazardous organic compounds, particularly halocarbons. These compact systems offer an alternative to existing incineration or post-incineration treatments, with the potential for closed-loop operation and millisecond response times. When combined with a packed bed precombustor, SDP allows both liquid and gaseous based waste streams to be treated with high destruction efficiencies. In stand-alone tests of the SDP reactor, gaseous influents containing 1000 ppm TCE (trichloroethylene) were reduced to below 100 ppb effluent. Other halocarbon solvents such as CCl{sub 4} (carbon tetrachloride) and TCA (trichloroethane) have also been treated. The measured figures of merit, electrical energy per mass of removed chemical, are 10`s of kW-hr/kg for {much_gt} 99% removal of TCE and 100`s of kW-hr/kg for 90% removal of CCl{sub 4}, both being for a non-optimized system. Future designs are projected to reduce toxic levels below 10 ppb, with high overall efficiencies.
