The tests of the dehalogenation system (removal of PCBs from insulating oil of transformers) destined to Macedonia have been completed positively. Besides the supply of the system, the Sea Marconi’s solution includes a mix of high level products and services for the correct 360° management of the PCBs problem. From one side, the services for transferring the know-how, such education and training courses within the Campus Sea Marconi, on the other side, the Macedonian customer will be able to benefit from a range of products such as, for example, kits for field analyses or the supply of checked and certified reagents by Sea Marconi. The final Customer shall have available a constant assistance service and all the necessary support, deriving from a unique experience in the sector, matured over 43 years of activity at international level.
Getting into details, about the system manufactured by Sea Marconi for Macedonia, it applies the proprietary technology CDP Process®, considered as BAT/BEP (Best Available Technique/ Best Environmental Practice) described also by the brochure CIGRE n. 413 “Insulating Oil Reclamation and Dechlorination” (April 2010).
The system is a batch type, i.e. in a fixed configuration; this means that the removal of the PCBs (dehalogenation) from the oils occurs essentially in three phases:
1. Draining the oil from the transformers
2. Taking the oil to the site dedicated to the dehalogenation
3. Dehalogenation process by the system developed by Sea Marconi.
The test performed at the Sea Marconi’s headquarters provided excellent results: an oil with an initial contamination of PCBs at 109 mg/kg, after only 6 hours of treatment resulted with a concentration of PCBs below 2 mg/kg, thus meaning it was PCBs-free.
