SunOhio, a Sun Co. Inc. subsidiary, has developed the PCBX process to eliminate PCB's from insulating fluids without destroying the fluids. The process uses ''reasonably priced'' reagents that strip the chlorine from the PCB to generate harmless residues, and follows this step with selective filtration, dehydration, and degassing. According to SunOhio, approx. 15 gpm of fluid can be processed, permitting the rapid removal and return of fluids to electrical equipment, possibly during continuous operation of the equipment. The PCBX process has reduced the concentration of PCB's in intentionally contaminated transformer oil from 178 ppm to zero. EPA is optimistic that PCBX will satisfy the requirement of being at least as good as incineration in eliminating PCB's, without imposing unreasonable risk to health or the environment. SunOhio feels that the PCBX process is less complex and works faster and more completely than a PCB removal method recently developed by Goodyear Tire and Rubber Co.
