Decontamination of PCB Contaminated Electrical Equipment Using INT Process for Simultaneous Dechlorination, Desulphurization and Regeneration of Mineral Insulating Oils
Implementation period: 2015-2018Location: Republic of Serbia, Power SectorTask: Eliminate PCB’s in RS acc. to NIPPCB’s in Electrical Equipment

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)
