Bienvenido a AGR Líder en Gestión Integral de Residuos Peligrosos con PCB

AGR It has the only plant in Spain with this technology, which allows it to decontaminate the oil with up to 7,000 ppm of PCB for reuse.
Decontaminated oil can be used as base oil for the manufacture of new industrial oils or it can be regenerated for reuse as dielectric oil.
In the process, a non-hazardous residue composed of oil sludge and NaCl is produced due to the reaction between the Na and Cl of the PCB molecule.
Oil contaminated with PCBs in a known concentration is stored in tanks and, before being introduced into the reactor, undergoes a dehydration process until it is less than 5 ppm of water content. On the other hand, the dispersion of metallic sodium, usually 40%, in dielectric oil is prepared.
Finally, measured amounts of contaminated oil and sodium dispersion are introduced into the reactor. The reaction stage lasts approximately 15 minutes and decontaminated oil and oil sludge with NaCl is obtained and separated by centrifugation.
