Title: Evaluation and development of polychlorinated biphenyl removal processes

Technical Report ·
OSTI ID:5308038

Process development studies are in progress to develop and evaluate chemical methods for removal of polychlorinated biphenyl (PCB) from waste oils. These development studies have included laboratory tests on reported commercial PCB destruction processes as well as separation methods such as evaporation/distillation, absorption, and solvent extraction. The test results obtained in these studies show significant decreases in PCB concentration using the sodium napthalide and sodium polyethylene glycol reactions. Evaporation/distillation studies successfully produced a PCB-free oil and a concentrated PCB-oil fraction. Development of a solvent extraction process is in progress, and several solvents have been found to remove PCB from mineral oil. Water can be used as a stripping agent to remove the PCB from the solvent into a third phase. This process will continue to be further developed through the pilot plant stage.
