Description
Summary:Relevance. Currently, the rational and economical use of petroleum products is of particular importance. This applies, among other things, to all known types of oils. Waste oils entering the natural environment are only partially neutralized as a result of natural processes. Most of them are a source of pollution of soils, water bodies and atmospheric air, leading to disruption of the reproduction of birds, fish, mammals, and having a harmful effect on humans. Thus, the widespread problem of collecting and recycling waste petroleum products is a relevant, cost-effective and knowledge-intensive area; since with the correct organization of regeneration, the cost of recovered oils is 40–70% lower than the cost of fresh oils with almost the same quality. Aim. To improve the technology of recycling spent petroleum products in the conditions of the northern territories in order to achieve eco- and energy efficiency. After the regeneration stage, used oils can be used for their intended purpose – returned to equipment lubrication systems, this is up to 75–80% of the original amount of waste oil generated. The remaining, “unrecovered” amount of 20–25% is burned in the form of a water-fuel mixture at enterprises equipped with liquid fuel boilers. The information available in the literature is insufficient to create an effective system for the disposal of used oils and other petroleum products, especially in the circumpolar territories. A differentiated approach to the problem is required, taking into account the peculiarities of the climate, the remoteness of the Arctic territories from the transport infrastructure, with mandatory compliance with environmental standards. Methods. cavitation technology (i. e. cavitation effects) and the LSTM (Long Short-Term Memory) deep learning method for processing hydrocarbon waste using the example of industrial oil W30 and, accordingly, modeling the migration of pollutants from industrial objects in open natural water sources. Results and conclusions. The results obtained indicate ...
