Evalution Of The Sunohio PCBX Process For Reclamation Of Transformer Oils Containing PCBs

The Sunohio PCBX process, a chemical destruction process, was closely examined for its use in removing PCBs from and in reclaiming PCB-contaminated mineral oils for reuse. The PCBX process effectively removed PCBs from a concentration of 1100 ppm to. 2 ppm or less; however, improvement of the oil quality from the untreated to the treated state was not statistically significant. Most of the treated oil qualities were satisfactory in physical and chemical properties; however, some of the treated oil qualities were not acceptable in electrical properties. The liquid waste produced was about 10 percent of the oil being processed. The waste was hazardous because of its high pH. The ambient air quality was monitored and determined not hazardous. The PCBX process appeared to be a cost-effective alternative to treat transformer oils containing PCBs.
