Removal of Corrosive Sulfur from Insulating Oils by Natural Sorbent and Liquid-Liquid.

Popis výsledku v původním jazyce

Prevention of energy transformer failures by removing so-called corrosive sulfur from insulation oil belongs to the most important tasks. This article is focused on finding an effective way suitable for decontamination of mineral insulation oils containing sulfur compounds together with regeneration of the insulation oils. Two methods were suggested and optimized, sorption technique on the newly suggested natural sorbents, bentonites, and liquid-liquid extraction with subsequent sorption. The effectiveness of proposed methods was compared with the common technique of filtration through a layer of commercially available Fuller’s earth. The real insulation oil from transformers with relatively high content of dibenzyl disulfide - 71.6 mg kg-1 was applied in all tests. Both suggested methods revealed a high efficiency of a corrosive sulfur removal and both bentonites possessed significantly better sorption properties than the commercial regenerated Fuller’s earth. Moreover, technological characteristics of regenerated oils by both methods met all requirements of the standards no. CSN EN 60422 and their properties corresponded to the new electro-insulation oils.
