Annually tens of thousands of tons of waste synthetic and mineral oils are accumulated on the territories of each industrialized country. They are highly toxic, they have low level of biodegradability (10-30%) and by accumulating in the environment they disturb an ecological balance. Existing regulations require mandatory collecting and recycling of waste oils and in some cases even their destruction. At the same time the EEC Directive proposes to consider waste oils not destructed, but reused.
To neutralize wastes effectively it is necessary to apply environmentally safe and economical technologies. With existing waste oil so diverse in chemical composition, a one universal method of transformer oil recycling is simply impossible. Therefore the existing technologies of oil refinery and their reuse should be improved.
Oil reclamation is the best solution in recovery of waste oil properties with the purpose to reuse it. This approach has a perspective – with a developing trend in ecology – to prevent pollution, reduce toxicity in manufacturing processes and make them more effective. Oil reclamation of oils is an ecological approach. It prevents contamination. Because most lubricants are oil based. And their wastes are a significant source of contamination.
In general, the methods of waste oils recycling without refining may be divided into mechanical and technical (disposal in the natural environment and incineration in special furnaces as an additive to boiler fuel). Such technologies are relatively simple, but not environmentally safe.
Transformer oil recycling methods on the basis of refining are divided into:
- physicochemical;
- thermochemical;
- biological.
Physicochemical method is widely used in practice. It includes filtration, coagulation, extraction and separation. This method regenerates oil, but has a medium level of environmental safety.
Thermochemical method is a thermal and chemical splitting into components. It is more environmentally friendly, but at the same time it is difficult to implement technically.
Biological method involves a cultivation of microbial biomass from oil wastes, which then becomes organic carbon. A microbial biomass as a final product, can be used for different purposes.
Today the level of environmental safety is the most important criteria in choosing the method of recycling of waste oil. The higher is the level of environmental safety; the lower is its degree of impact on the environment.
GlobeCore adheres to the concept of clean production. This concept is in its product design and consumption. The main essence of clean production is renewable energy, recycled waste materials and minimum amount of resources used.
A method of waste oil purification is chosen according to environmental requirements:
- Degree of purity of the final product;
- Low-waste technology;
- Possibility of recycling waste;
- Easy waste disposal;
- Waste toxicity;
- Use of environmentally safe chemicals.
These factors are considered in designing and manufacturing of GlobeCore UVR oil reclamation unit. This equipment reclaim and purifies various types of oil: transformer, turbine, industrial oil as well as lightening fuel, dark heating oil, gas condensate, gasoline and kerosene.
GlobeCore UVR oil filtering units for oil reclamation fully conform to the concept of clean production and preserve ecological balance and make profit reusing waste oils.
