This module is designed for the processing of the liberated during the of disposal of<br />

drumsand preparation for shipment of scrap metal is formed as a secondary raw material forsteel<br />

plants. Description of the module and the basic technological processes carried out therein are<br />

given above, in Section 10.1.<br />

11.3.3 Procedures for conservation (liquidation) transformers, condensers and containers<br />

containing sovtol and other PCB-containing liquids.<br />

In the above mobile unit in modular design uses the same technology decontamination<br />

(washing), transformers, condensers and containers as drums [66]. It boils down to the washing<br />

of PCB-containing wastes with the subsequent elimination of this waste by mobile plant hightemperature<br />

oxidation and utilization of transformers, condensers and containers as scrap.<br />

Chemical processing are only liquid wastes with PCB content of about 90% and above. Oleum<br />

sulfonation source of PCB to further neutralize the product does not allow to reach the degree of<br />

conversion of PCB for more than 99%. This results in a product can contain more than 50 ppm<br />

PCB, which requires an additional step (distillation or leaching PCB) from the resulting paste<br />

PHDS-T. This paste can be applied to the archipelago to impregnate the wood from rot.<br />

The initial stage of decontamination technologies (cleaning), transformers, condensers and<br />

containers is in the preliminary washing their "assembly", then they are disassembled and<br />

additional washing of metal parts up to PCB on the surface of less than 50 ppm (mg / kg). Metal<br />

parts with such a low content of residual PCB belong to the European standards for nonhazardous<br />

waste and can be disposed of in any acceptable manner. The rest of the disassembly of<br />

the transformer, wooden and cardboard waste containing more than 50 ppm (mg / kg) of PCB are<br />

burned or to be disposed of in designated landfills in compliance with the stringent requirements<br />

of environmental safety.<br />

Design features of condensers allow them to render a similar technology, as well as transformers.<br />

Neutralization condensers, then throw shells provides washing condensers, their dismantling, a<br />

second wash the shells and the core. After this case, containing less than 50 ppm, sent for<br />

recycling, as crushed core and additionally washed from the PCB, usually a hot solvent. Peeled<br />

and crushed aluminum core contains less than 50 ppm PCB, and also sent for recycling.<br />

With regard to the peculiarities of the elimination sovtol and other PCB-containing liquids in the<br />

territory of the island of Alexandra Island, should use previously mentioned complex<br />

technology. To implement this it is worthwhile to highlight the most important stage.<br />

The first stage of technology should include the identification of waste, based on rapid methods<br />

and their subsequent movement of two to three industrial sites.<br />

In this case, the main goal of the event - the formation identified in the qualitative composition<br />

of the waste according to the degree of danger. Since most of the available drums, transformers<br />

and condensers are in poor condition, should be possible to retrieve the waste in drums or<br />

containers are safe.<br />

The second stage should be directed to carry out the neutralization of the liberated packaging<br />

(including - transformers and condensers), with subsequent compaction and recycling.<br />

Excepted transformers and condensers before compaction to be neutralized. This is a more<br />

complicated process than the neutralization of the drums after removal of PCB-containing<br />

FINAL REPORT for Contract No. CS-NPA-Arctic-13/2009 of December 01, 2009 within the framework of pilot project Development<br />

of Technology of clean up of the area of Decommissioned Sites of The Russian Federation Ministry of Defense in the Arctic by the<br />

Example of Alexanra Island of Franz Josef Land Archipelago from Hazardous Waste<br />
