Technological control of production of plastic lubricants by rheological properties
(VÚRUP, 2024) Grigorov, Andrey; Tulska, Alona Gennadiivna; Bondarenko, Oleksandr; Petukhova, Olena; Bryhada, Olena; Nahliuk, Mikhail
The article substantiates the importance of technological control of the production of plastic lubricants which characterizes physical, chemical or operational properties. Effective dynamic viscosity has been considered the most appropriate characteristics for technological control of for production of plastic lubricants. Effective dynamic viscosity of two-component plastic lubricant produced from secondary raw materials, as well as lubricants obtained using classical petroleum raw materials and soap thickeners, significantly depends on the viscosity of the base oil. It was defined that type of polymer thickener has rather insignificant effect on the value of the effective dynamic viscosity comparing to viscosity of the base oil. High-density polyethylene (HDPE) has the biggest thickening effect on the base oil, and polypropylene (PP) has the least. A diagram of location of the viscosity measuring sensors in the middle of the apparatus for dispersing the polymer thickener in base oil as a dispersion area was proposed. It helps to optimize the process of dispersing the polymer thickener by controlling the duration technological process that results in reducing the consumption of energy resources.
Determination of the optimal concentration of polymer thickener for production of plastic lubricants based on secondary raw materials
(VÚRUP, 2023) Grigorov, Andrey; Tulska, Alona Gennadiivna; Bondarenko, O.; Yurchenko, L.; Gornostal, Stella
The article substantiates the effect of the concentration of polymer thickener on such basic properties of the plastic lubricant as dripping temperature (td.p., °С) and adhesive properties (ADG). It was defined that, unlike (td.p., °С), the ADG indicator is more informative for defining the optimal concentration of the polymer thickener in plastic lubricants produced from secondary raw materials. Determination of the ADG indicator was performed in a laboratory centrifuge, based on the amount of plastic lubricant that remained on the metal plate after the study. This amount should be at the level of 50 % of the initial value. Experimental studies have shown that the optimal concentration in the composition of the lubricant is: in the case of HDPE, 5.0 % for SAE15W-40 oil, 4.3 % for SAE 75W-90 oil, 6.3 % for BP Energol CS68 and HLP-46 oil ; in the case of LDPE, this concentration is equal to 7.0 % for SAE15W 40 oil, 5.2 % for SAE 75W-90 oil, 7.4 % for BP Energol CS68 and HLP-46 oil; in the case of PP, this concentration is equal to 7.5 % for SAE15W-40 oil, 6.2 % for SAE 75W-90 oil, 8.0 % for BP Energol CS68 and HLP-46 oil.
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.
Recycling of Polymer Waste into Plastic Lubricants
(2022) Grigorov, Andrey; Sinkevich, Irina; Ponomarenko, Natalia; Bondarenko, Oleksandr; Usachov, Dmytro; Matukhno, Vasyl; Shevchuk, Oleksandr
A technology for the production of greases from polymeric household waste has been proposed, including the stage of boiling the polymer in a solvent, which is used as a used motor oil SAE10W-40. In the production of greases using this technology, a significant amount of used polymer products is utilized, while the share of waste from low-pressure polyethylene and polypropylene (PP) is, respectively, 20-50% of the mass and 50-75% of the mass. This approach makes it possible to significantly expand the raw material base of the specified technological process and, due to the involvement of relatively cheap raw materials, significantly reduce the cost of finished products. The results of the study of the adhesive properties of the obtained lubricants allow us to give the following recommendations: for lubricants based on low-pressure polyethylene with a polymer: oil ratio of 1: 1, the rational rotation speed was no more than 2850 rpm, with a ratio of 1: 3 - about 3950 rpm and with a ratio of 1 : 5 - up to 5300 rpm; rational rotation speed for lubricants based on PP at a polymer: oil ratio of 1: 1 does not exceed 3600 rpm, at a ratio of 2: 1- 4900 rpm and at a ratio of 3: 1 - 6000 rpm.
Compatibility of Recycling Plastic Lubricants
(2023) Grigorov, Andrey; Ponomarenko, Vitaliy; Slepuzhnikov, Yevhen; Bondarenko, Oleksandr; Artemev, Sergey; Ilinskyi, Oleksii; Bryhada, Olena
The compatibility of recycled greases thickened with 5 % (wt.) polyethylene and polypropylene solid waste was studied. It was found that according to the values of the dropping point and adhesive properties, recycled greases, regardless of the base oil and thickener, are compatible. However, when 10 % (mass) of recycled lubricants are added to Solidol "Zh", its adhesion properties deteriorate by 300-400 rpm, due to the negative effect of the aging products of base oils on its structure, which indicates their incompatibility.
Adhesion properties of modified bitumen
(2020) Grigorov, Andrey; Mardupenko, Aleksey; Sinkevich, Irina; Tulskaya, Alena
The article presents the results of determining the adhesion properties of bitumen modified with polymeric additives based on polypropylene and polystyrene foam with graphite additives. It has been found that a sample with the addition of 3% (mass.) Polypropylene (peel strength of the plate 2.47 N/cm²; peel of the coating from the marble plate at a speed of 7000 rpm; shift of marble plates by 5000 rpm) has the best adhesive properties. And at a polymer concentration of 10% (mass.), The best properties are manifested in a sample containing polystyrene foam with graphite additives (plate tear-off force 3.15 N/cm²; tear-off occurs at a speed of 8000 rpm; marble plates shift by 8000 rpm ).
Selection of a dispersion medium for recycling plastic greases according to fire and explosion indicators
(2020) Grigorov, Andrey; Sytnik, Alexey; Ponomarenko, Natalia; Neustroieva, Gelena; Nahliuk, Mikhail
The article presents the results of determining fire and explosion hazard indicators for used lubricants, which are supposed to be used as a dispersion medium in the production of recycling plastic greases. Having determined the flash point of the oils, it is possible to calculate the values of the ignition temperature and self-ignition according to linear regression equations, with an error of up to 2 °C. The flash point can be a criterion when choosing raw materials and layout of the technological scheme for the production of recycling plastic greases.
Possibility of producing plastic lubricants by thermal destruction of solid domestic wastes
(2020) Grigorov, Andrey; Zelenskii, Oleg; Sytnik, Alexey; Nahliuk, Ivan
The results of non-catalytic thermal destructive processing of solid domestic waste at atmospheric pressure and temperature of 360°C, which are represented by products of low pressure polyethylene, are presented. The products obtained during degradation can be divided into fuel products (gas, liquid hydrocarbon fraction, coke residue) and fraction (with the beginning of boiling in the temperature range 200-320°C), which can be used in the production of greases. After the heat treatment and cooling of these fractions, a product with properties similar to NYCO 65 VASELINE (Technical petrolatum (GREASE)) can be obtained. For the production of plastic lubricants with other properties and a large temperature interval of application, a scheme has been proposed, it provides for the addition of fillers and additives of different functional purpose to the lubricant obtained.
