Abstract
A mobile plasma arc system for the destruction of liquid hazardous wastes has been designed and constructed. The pyrolytic destruction process produces acid gas, a fuel gas, and finely divided carbon. The acid gas is removed in a caustic scrubber, which also captures most of the carbon; the fuel gas is flared. The system has a design feed-rate of 4 kg/min. The operation of the system has been tested in a series of short-term runs using methyl ethyl ketone/methanol, carbon tetrachloride, and PCBs as feed materials. Removal efficiencies, greater than 106 were obtained for the chlorinated hydrocarbons and the emissions from the system.
