A few days ago the fabrication of a plant for Mongolia, finalised toward the dehalogenation of electrical equipment with insulating liquids contaminated by PCBs was completed. This plant is of a DMU (Decontamination Mobile Unit) type with extremely innovative configuration and technical solutions. It is a plant made of two modules designed and developed in a manner allowing the operators to work inside the unit, a very appreciated feature in view of the extremely harsh temperature conditions in Mongolia. The removable covering structure has four struts, providing a higher flexibility during the lifting phases and thanks to the supporting frame equipped with corners in accordance with norm ISO 1161, it can be transported on the platform of a lorry secured by appropriate twist-locks.
On 8th August, with the presence of the Customer’s representative, the plant was tested providing a dehalogenation treatment of oil contaminated by PCBs at 72 mg/kg. The new DMU assured excellent performances decontaminating the oil to 2 mg/kg in just 24 hours thanks also to a delivery of 5000 l/h.
The plant just completed exploits, obviously, the proprietary technology CDP Process®, considered as BAT/BEP (Best Available Technique / Best Environmental Practice) and described also in the brochure CIGRE no. 413 “Insulating Oil Reclamation and Dechlorination” (April 2010).
Besides the supply of the plant, the SEA Marconi solution includes a mix of high level products and services finalised toward a correct management of the PCBs problem at 360 degrees, such as education and training sessions, the provision of the newest kits for field analyses and naturally the supply of the reagents (patented by Sea Marconi), which, in contact with the contaminated oil, are capable of dechlorinating/decontaminating the PCBs.
