Decontamination of Oils Contaminated with Polychlorinated Biphenyls and Dibenzyl Disulfide Using Polar Aprotic Solvents

Popis výsledku v původním jazyce

The highest efficiency, around 70 % in single-step extraction exhibited NMP. NMP was evaluated as having the best chance to be used in industry. It was shown that for some transformer oils the separation of corrosive sulfur with the common technique of filtration through a layer of commercially available sorbent (for example Fuller?s earth) is totally inadequate. However, extraction efficiency of DBDS from contaminated transformer oil with the help of NMP is sufficiently high over 99 % and feasible in afair time of about 20 minutes. The remaining concentration of DBDS after single-step extraction from transformer oil containing up to100 ppm DBDS was low enough (approx. 0.1 ppm or non-detectable). Detection of corrosive sulfur in transformer oil afterextraction with NMP has been also performed by Siemens test method (IEC 62535) and by updated ASTM 1275B proposed by CIGRE Covered Conductor Deposition test method and was negative. It is possible to consider the transformer oil after the
