FENIX SUPERIOR SAE 15W-40, produced by manufacturer Joint Stock Company FAM Krusevac, is used for lubrication of the most modern four-stroke diesel and gas engines of passenger and commercial vehicles, engine construction, mining and agricultural machinery, as well as stationary power aggregates including highly overloaded engines working in harsh environmental conditions. Exhausted oil samples was obtained from the three sources: diesel and gas engines of passenger cars and agricultural machines – tractors were treated according to novel two step technology. In first step physical operations such as centrifugation, filtration and separation was applied in order to remove mechanical impurities (sludge), condensed material and water. In the second step chemical oxidation, using three agents: hydrogen peroxide, sodium hypochlorite, and potassium persulfate was applied to achieve removal of the sulfur containing compounds. Based on obtained results at laboratory level, a technology at semi-industrial level for the treatment of waste oil was proposed. New ecologically friendly technology developed for treatment of waste oil offer appropriate advantages in comparison to commercially available technologies.
