Abstract
A method and apparatus for the destruction of PCBs and other hazardous material utilizes a gas-tight chamber (18) which includes a high current DC arc (72). The chamber (18) is adapted to receive the PCBs or other hazardous material and includes a sump (20) which contains a molten bath (22). Inlet means (24, 26, 28) are provided for introducing the hazardous material into the chamber (18) and into contact with the molten bath (22) for initial decomposition into a molten product and a gaseous product. Electrode means (66, 68) are provided for maintaining the DC arc (72) at a current level sufficient to promote decomposition of the PCBs or other hazardous material. The gaseous product is passed in the proximity of the arc (72) for producing a decomposed gaseous product which is relatively harmless. The system is capable of decomposition of solid, liquid and gaseous PCBs, as well as other hazardous material.
