Recovery of Oil: the Myths, Reality, Mechanisms

Economic development of mankind is a sine curve: a rise is eventually replaced with decline and vice versa. The only change is duration of each state. It is inevitable that individual countries and the entire international community will periodically appear in economic crises. Thus the issues on savings and reuse of waste materials, as well as recovery of worn out machinery are particularly actual. Oil market looks particularly vulnerable. A lot of countries that do not possess own fuel resources, are dependent on the prices of “black gold”. A large share of oil products used is: motor, transformer, industrial, turbine and gear oil, etc. The global consumption of motor oil , as shown by simple calculations, is about 60 million tonne of oil equivalent. On average 10 tons of engine oil is received from 100 tons of crude oil. But if you take the same 100 tons of waste oil and process it properly, it is quite possible to refill the fuel reserves with 80 tons of ready to use product. An operation of oil leads to oxidative processes, with accumulation of byproducts: varnish deposits, asphaltic compounds, etc. Under normal conditions they precipitate, which is very undesirable. Designers have come up with a solution: to maintain the oxidation products in suspension. To achieve this effect detergent-dispersant additives are introduced into oil. It is worth remembering that virtually all types of petroleum oils are very dangerous wastes, polluting the environment. It is strictly forbidden to pour used oil on the ground, in drains or in trash cans. Once in the environment, oil decomposes sufficiently long, since it is not soluble and a chemically stable substance. The situation can be complicated by a very rapid spread of waste oil from the drain. Due to its viscosity, oil can stick to almost everything, from sand to feathers of migratory birds. The problem of disposing of waste oils can be proved by any transportation company. The lack of serious funding does not contribute to collection, storage, transportation and processing of waste oils and lubricants. The new solutions should require minimal costs, be highly technical and economically efficient with fast return of capital investment. Resolution is – a recovery of waste oil with possibility of further use. So what exactly does “recovery of waste oil” mean? The first sign of such product – is the color and smell of fresh oil. Furthermore, recovery removes acid, various deposition, precipitation, mechanical impurity gases, water vapor and other substances that reduce the braking performance and physico-chemical composition of oil. Each recovery mechanism achieves a few fractions of base oils, which are later processed into a market product. For example, from a fraction recovered from motor oils – coolants, greases, transmission and hydraulic oils are successfully produced. At present, there are enough ways to recover waste oils. Each of them has advantages and disadvantages. Standard regeneration schemes are multi-stage processes. First free water and solids are mechanically removed, then it goes through evaporation. If necessary (an insufficient degree of purification after the first stage) resorts to physical-chemical treatment. The top recovery of waste oil obtains a product, superior in performance to oil before processing. In practice, it is possible, by using chemical methods that are complex and costly. Therefore, there is a search for the best solutions in terms of price and performance characteristics. And this solution exists! GlobeCore offers universal equipment designed to recover transformer oil, industrial oil, turbine oil, gear and other types of oils, as well as diesel (it brings the fuel economy) and heating oil, gasoline, gas condensate, etc. Many years of experience in developing installations for processing oil and using innovative technologies allows creating versatile, economical and easy-to-use equipment. GlobeCore individually approaches each client, and besides mass production, there is a private production – fitting technical task of specified by a client. Waste oil recovered by GlobeCore plants has all the parameters necessary for further use. The equipment is certified and physico-chemical characteristics of the treated oil fully comply with existing standards and requirements, the evidence is a successful operation of GlobeCore oil installations in more than 70 countries.
