  • Transformer oil quality control

    It is impossible to ensure reliability and longevity of energy systems without controlling the quality of transformer oil. Recent experience shows that approximately 30% of transformer oil, filled in power transformers, has deteriorated to the point when it becomes a risk factor. This is caused both to natural degradation of oil in operation due to thermal oxidation aging, and contamination with ...

  • On-site regeneration of transformer oil

    Regeneration of transformer oil at the transformer’s location is an important preventive measure of transformer servicing.   Transformer life time is, in essence, the life time of its insulation system. The most widely used insulation is liquid insulation (transformer oils) and solid insulation (paper, i.e. cellulose insulation). The oil provides for at ...

  • Transformer Oil Hydrotreating case study

    Hydrogenation of waste transformer oil (electrical insulating oils) can produce an oil product that is far better in quality and yield in comparison with fixed bed clay adsorption or reaction with sodium metal. This is proven at Sequoia- client’s facility in Midwestern USA. The 5 million gallon/year throughput naphthenic oil hydrotreater produces oil free of PCBs (polychlorobiphenyls ...

  • Modelling oil degradation in electric transformer oil under typical loads

    In testing transformer oils for durability, it is desirable to use typical transformer operating conditions with appropriate allowances for factor of safety against temperature and voltage. The kinetics of degradation of used type II transformer oil with original flash point of 148?C, pour point of 51?C, and water content of 4 ppm was investigated. Assuming that the oil temperature in models Pr01 ...

  • Isolation, development and identification of salt-tolerant bacterial consortium from crude-oil-contaminated soil for degradation of di-azo dye Reactive Blue 220

    The objective of this study was development and characterization of a halophilic bacterial consortium for rapid decolorization and degradation of a wide range of dyes and their mixtures. The 16S rRNA gene analysis of developed halophilic consortium VN.1 showed that the bacterial consortium contained six bacterial strains, which were identified as Pseudomonas fluorescens HM480360, ...

  • Regeneration of used oil

    Used oil regeneration technologies Over time, oil accumulates oxidation products, contaminants and impurities which drastically reduce its quality. Contaminated oil can no longer meet quality requirements and must be changed. Waste oil is collected and regenerated to retain valuable basic materials. Oil cannot be recycled at petroleum processing plants with ...

    ABSTRACTThe SPCC regulations entail numerous requirements for the storage of oil. The intent of this paper is to summarize several of the complex requirements associated with oil storage at a facility subject to the SPCC regulations. INTRODUCTIONThe Spill Prevention, Control, and Countermeasure (SPCC) regulations are far reaching requirements promulgated by the ...

  • Moisture in Oils: The Three-Headed Beast

    Abstract Moisture contamination in in-service lube oils is perhaps one of the most destructive forms of engine corrosion second only to particle contamination.  Water contamination in oil can be categorized into three forms of water; Free, emulsified, and dissolved.  All forms of water have direct consequences to the oil and gears of the engine, but indirect consequences as ...

  • Surface Decontamination of PCBs (PCB-laden oil) by DeconGel 1101 and 1102

    Abstract Field testing aboard the USS Missouri maritime museum vessel showed that excellent surface decontamination was achieved by applying DeconGel™ 1102 onto contaminated surfaces, resulting in encapsulation of PCB contaminant by DeconGel's active components. For all contaminated surfaces tested, EPA PCB limit standards (Regulations 761.79, 761.123) of < 10 ug/100 cm2 were ...

  • How did palm oil become such a problem — and what can we do about it?

    Production of this ubiquitous ingredient is devastating for the environment. Solutions are complex, but they are out there. Last August, from the window of a jet high over Sumatra, I counted nearly a dozen plumes of smoke rising from the vast jungles and plantations below. Some more than a half-mile wide, they looked like pillars holding up the sky. That week the ...
