Abstract

The article provides analytical information on the study of methods of treatment of used engine oils. The issues of ecological safety of storage, processing and use of automobile waste are considered. The problems of ecological safety of application of lubricants are inseparable from utilization of OWS, which are currently one of the most common man-caused waste that negatively affects all objects of environment - atmosphere, soil and water. It has been shown that water pollution by waste oil accounts for 20% of total techno-genic pollution, or 60% of petroleum product pollution. The study determined that obtaining oils with characteristics superior to the original properties of the product received for regeneration is possible in addition to various stages of OM treatment requiring the use of chemical regeneration methods associated with the use of complex equipment and high costs. An improved combined processing scheme for used motor, industrial, turbine and transformer oils is analysed, the scheme of which involves coagulation, atmospheric distillation, acid and adsorption purification stages followed by vacuum distillation and contact refining of the high-viscosity component.
