    Decontamination of PCB Contaminated Electrical Equipment Using INT Process for Simultaneous Dechlorination, Desulphurization and Regeneration of Mineral Insulating Oils

    Implementation period: 2015-2018 Location: Republic of Serbia, Power Sector Task: Eliminate PCB’s in RS acc. to NIPPCB’s in Electrical Equipment

    C(PCB) = 50-500 mg/kg

    C (PCB) >500 mg/kgStockholm Convention PCB limited to 50 mg/kg in electrical equipment in service New equipment and oils PCB free

    Sources of PCB Contamination • Oil treatments (oil tanks, machines for oil

    treatment) • Oil change and topping up (oil tanks, machines

    for oil treatment) • Repair of transformers (TR workshops and

    factories, oil tanks) Section 1 Section 2 Section 3 Section 4 Section 5

    CONCLUSION • INT process is efficient in the removal of PCB,

    corrosive sulphur and ageing products from mineral insulating oils

    • After treatment Oils and transformers have “extended life” and improved properties for further use

    • INT process can be used for treatment of mineral oils and equipment after “end of life” (waste treatment)
