Abstract
A method and apparatus for removal of PCBs or similar refractory organic substances from solid surfaces, such as soil or hardware, e.g., capacitors and transformers containing a charge or residue of PCB or similar fluids. Such toxic substances are volatilized from substrates contaminated therewith by contacting them with carrier gas, such as a mixture of hydrogen, carbon monoxide and steam. The carrier gas and volatilized components are introduced into a partial oxidation zone of a gas generator where PCBs are completely destroyed at a temperature range of 2800.degree. F. to 3500.degree. F.
