Evaluation of Carbon for Removal and Destruction of Polychlorinated Biphenyls (PCBs) from Transformer Mineral Oils
Adsorptive removal of PCBs by carbon followed by destruction through an oxidative carbon regeneration process were evaluated. The combined processes performed well for PCBs with lower chlorine content. Adsorption efficiencies of ≥ 95% were achieved for lower chlorinated PCB formulations such as Aroclor 1240, adsorption efficiencies for higher chlorinated PCBs were considerably lower. The regeneration process was highly effective and ≥ 99.7% of the adsorbed PCBs were mineralized or converted to unrecoverable forms.
