Transformer oil recycling

Nowadays, the largest volume of production and consumption among all lubricating oils belongs to petroleum-based oils. The tendency to increase the output of this product can be traced quite clearly, which requires the introduction of new and improvement of existing methods of collection, processing and regeneration.


One of the most economical ways to handle secondary resources is the transformer oil recycling directly at the point of consumption. Some experts consider the aging process to be irreversible and have little impact on the service life of lubricating oil products. More attention should be paid to various foreign impurities, which, accumulating in the oil, significantly impair its quality. Mechanical cleaning methods can solve this problem and contribute to the reuse of lubricants for their intended purpose. To a greater extent this applies to transformer, turbine, industrial and hydraulic oils, and to a lesser extent to engine oils. Although it is the latter that are confidently leading in terms of production.


Regeneration of waste oils is performed using physical, chemical and physicochemical methods. To date, the most commonly used physical methods to which they belong: sedimentation, filtration, centrifugation and vacuum drying. Physico-chemical and chemical methods are more complex, therefore, they are applied only in the case of the presence of severe contamination or deep aging of oils.


To provide good prerequisites for the future processing of contaminated oil, its collection should be carried out separately by brand. This allows you to reduce the amount of potential waste and get a high quality product at the outlet.


Every year around 15 million tons of waste oils are collected in the world, and from 70 to 90% of such raw materials are used as fuel. In many countries, centralized collection and disposal has not been established yet, so the data are approximate.


Among the most commonly used methods of disposal of waste oils are the following:


  • reprocessing or purification of certain impurities in order to obtain boiler fuel;
  • recycling to obtain base components;
  • separate regeneration to obtain a product suitable for use for its intended purpose.


If the ultimate goal of recycling waste oil is to obtain basic components, then regeneration provides for the complete restoration of the properties of the processed oil to its original values. It is quite logical that such a product can be used further for its intended purpose. The benefits of regeneration are obvious: no need to spend money on the purchase of fresh petroleum products for the replacement, problems of emissions of harmful substances into the environment are solved.GlobeCore is one of the leading manufacturers and suppliers of equipment for the regeneration of transformer, turbine, industrial and other types of oils. GlobeCore processes are based on both classical and innovative approaches proposed by the design department of the company.
