Thermal phase separation for PCBs and oilfield wastes demonstrated in Quebec

A certificate has been obtained by SCC Environmental from the Quebec Ministry of Environment to demonstrate thermal phase separation (TPS) technology that separates contaminants from soils, sediments and sludges. The TPS process is a closed-loop, two-stage controlled thermal treatment and condensation and separation process, designed to remove chlorinated and non-chlorinated contaminants such as PCBs, PCP, PAH, chlorobenzenes, pesticides and insecticides from soils, sludges and sediments. During the process, organics from the soil are volatilized through indirect heat. The condensing gases are separated into oil, water and sludge fractions. The water is treated by sand filtration and activated carbon adsorption. Contaminants are sent to safe disposal. The tests will be conducted to verify the stability and reliability of the process. 1 tab., 2 figs
