MAQOLA ANNOTATSIYASI

The article investigates the problem of collection and recycling of waste oil products, which is an urgent, moreover, a cost-effective and scienceintensive field, because if the regeneration process is organized correctly, the cost of regenerated oils is 40-70% lower than that of fresh oils, while their quality is virtually the same. The possibility of using waste synthetic oils as fuels, which have, however, a lower combustion heat than OM, was investigated. It was determined that unlike ester oils which mix with petroleum oils, PAHs form a two-phase system with the latter, which creates difficulties in pumping and injecting such fuels. The proposal of a method to regenerate fluorinated oils such as perfluoropolyethers, perfluoropolyphenyl ethers, and thiazine perfluoropolyethers using different halogencontaining solvents or their mixtures for lubricant cleaning is analyze. The rational use of OM for the production of solid fuels by solidification and briquetting has been investigated. It has been determined that the above-mentioned environmental and economic problems in the production of OM fuels will contribute to the development of the production of more expensive base oils from OM. It has been determined that the physical methods used to pre-treat waste oils are not suitable for the purpose of producing environmentally friendly fuels, especially with regard to the subsequent emission of particulates, halogens and metals such as lead and copper (the presence of particulates in oils is a consequence of the wear of lubricating equipment).
