    Dielectric Control of Motor Fuel Compounding Plants
    (2022) Sater, Nabil Abdel; Grigorov, Andrey; Neustroieva, Gelena; Bondarenko, Oleksandr; Matukhno, Vasyl; Vavreniuk, Sergii
    The article proposes the use of operational dielectric control system to increase the efficiency of operation of automatic compounding of motor fuels. These plants are used at oil refining enterprises in Ukraine and are an integral part of the technological chain of the commercial fuels production. It is established that all the main components and additives used for the production of commercial gasoline brands A-92, A-95 and A-98 have higher values (εmix) than straight run base gasoline. And this, in turn, can be used for operational control of the gasoline compounding process. This control can be carried out on the basis of the information received from capacitive sensors which are located in pipelines of the main material streams. Moreover, the control is carried out on the content of components (X, %) or on the value of the octane number (ON, point) of the mixture on the basis of experimentally obtained dependences 𝜀𝜀mix=𝑓𝑓(𝑋𝑋) and ОN=𝑓𝑓(𝜀𝜀mix).

    Modern Trends in The Use of Additives in Fuel and Oil Materials (Overview)
    (2022) Trotsenko, Oleksandr; Grigorov, Andrey; Nazarov, Valerii; Nahliuk, Mikhail
    Domestic and foreign literature data were reviewed on the conditions and features of additives use, their required content in fuel and oil materials, and the study of their characteristics in order to systematize data on additives used to improve the operational properties of fuel and oil materials. The use of additives in the composition of fuel and oil materials can significantly increase the level of their operational properties, without serious production costs associated with deep cleaning and preliminary preparation of raw products, compounding of raw products, technical re-equipment of production, etc. A list of additives was offered to fuel and oil materials used in the world practice of their production and application, added with dyes. These additives should be included in the main package of production branded premium fuel and oil materials, create their classification, simplify the procedure for identifying different batches, simplify the procedure for transportation, storage and distribution of fuel and oil materials. At the same time, among all the variety of dyes that are currently used for coloring to fuel and oil materials, the most appropriate is to use those that carry out multifunctional properties. These properties, depending on the type of materials, along with the color, can be density, detonation resistance, anti-corrosion. This approach, on one hand, will allow to balance the amount and properties of additives included in the overall package, on the other hand - will reduce production cost of the fuel and oil materials.

    The prospects of obtaining plastic greases from secondary hydrocarbon raw material
    (2018) Grigorov, Andrey; Zelenskii, Oleg; Sytnik, Alexey
    The paper presents the results of producing lubricating grease from industrial and household waste in the laboratory. Partially prepared diesel engine oil SAE 10W-40 was used as a dispersion environment, and high and low pressure polyethylene (household polyethylene bags used) was used as thickener. It has been established that by using selected base oil, thickener and anti-wear additive DF-11, recy-cling oils can be obtained, which will be classified according to DIN 51502 to K2PF-30 and K3PF-30. It is proposed to expand the raw material base for the production of recycling oils through the using of waste industrial, hydraulic, transmission oils, as well as high-boiling petroleum fractions extracted from oil sludge or acidic tar and selective waste distillate oils. On the basis of the analysis of the researching results, it was established that on the basis of exhausting motor oil and polyethylene with the addition of additives of different functional purpose, it is possible to obtain a number of antifriction plastic lub-ricants used in swing bearings, railway and protective greases that can be used in the range of oper-ating temperatures, on average up to 100ºC.
