Decontamination of oils contaminated with PCB by metallic sodium

Decontamination of oils contaminated with PCB by metallic sodium

AGR has the 2nd plant of Europe with this technology that allows us to decontaminate the oil with PCB up to 2500 ppm and reuse it.

The residue generated in the process is NaCl, i.e. common salt that is a non-hazardous waste.If the PCB content in the oil is less than 2500 ppm the transformer can be recovered for reuse.

The decontaminated oil can be used as base oil for the manufacture of other types of oils by adding the corresponding additive either or regenerate it and, by additivation, for use as dielectric oil.

GUARANTEES

Mineral oil with PCB transformers decontaminated in AGR are guaranteed their decontamination of PCB during the life of the transformer.

The PCB contaminated oil stored in a tank is dried by two filtering equipments of treatment, reaching less than 5 ppm of water, its PCB content is analyzed and is introduced into the reactor.

Sodium is crushed and dispersion to 40% is made with dielectric oil and is introduced into the reactor. 10 Minutes after the reaction is completed, its centrifuged and gets decontaminated oil and NaCl (common salt) which is deposited in landfill.
