Документ Adhesion properties of modified bitumen(2020) Grigorov, Andrey; Mardupenko, Aleksey; Sinkevich, Irina; Tulskaya, AlenaThe 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 ).Документ The choice of method of dispersion the thickener for the production of the recycling plastic grease(2019) Grigorov, Andrey; Tulskaya, Alena; Nahliuk, Mykhailo; Karchakova, ValeriiaThe results of dispersing the thickener in the area of grease using a paddle stirrer (rotational speed = 100 and 1000 rpm) and ultrasonic treatment with a frequency of 44 kHz have been presented. It has been concluded that ultrasonic dispersion allows us to increase the dispersion of the thickener up to 3-5 microns and spread it evenly in the grease comparing to the mechanical dispersion. Increasing the degree of dispersion of the thickener allows improving the stability of the obtained grease, its adhesive properties. Also it allows reducing the duration of the process of greases producing.Документ Technology of modified bitumen production for the road construction(2019) Mardupenko, Aleksey; Grigorov, Andrey; Sinkevich, Irina; Tulskaya, AlenaIn the current article, there has been proposed technology of production of the modified bitumen that is based on the compounding of petroleum residue with solid domestic wastes at 420–470K. The advantages of technology are compactness of technological scheme, simplicity of technological equip-ment, and minimal hazardous emission. There have been obtained laboratory samples with the pro-perties that exceed the properties of commodity bitumen PRB-90/130 (petroleum road bitumen). The produced modified bitumen has expanded temperature range of application, which makes the bitumen universal for any climatic exploitation zone.Документ Ways of improving the equipment for primary petroleum refining(2019) Sater, Nabil Abdul; Grigorov, Andrey; Tulskaya, Alena; Ovsiannikova, Tatiana; Sytnik, AlexeyThe general ways of improvement the primary petroleum refining rigs have been described in this article. It has been proposed to consider the operational control of primary petroleum refining processes as the most perspective branch of petroleum industry due to its comparatively cheap implementation. Operational control has a significant influence on the safe operation of equipment, products quality and amount of harmful emissions. Electrical conductivity and relative permittivity have been defined as the specific parameters for effective operational control.Primary oil refining rigs are the most important part of any petroleum refinery. Despite the Nelson complexity index which is only 1,0 for refineries it should be considered that they have a strong impact on the secondary refining rigs. That’s why one of the most important task in the petroleum refining industry worldwide is improvement of primary oil refining rigs.Документ Production of boiler and furnace fuels from domestic wastes (polyethylene items)(2018) Grigorov, Andrey; Mardupenko, Aleksey; Sinkevich, Irina; Tulskaya, Alena; Zelenskyi, OlegThe results of the thermal destruction of solid domestic waste (which are polyethylene items) were presented for batch-type laboratory equipment. According to the modern requirements of EU for the amount of sulphur in fuel and boiler fuels, polyethylene items are a valuable source for pro-duction of these fuels. During atmospheric heating of the raw material in reactor the intensive destruction of polyethylene can be observed in the range of temperature 560–580 K. It has been defined the composition of products of polyethylene thermal destruction: 95 % (mass.) of liquid hydrocarbons, 4,5 % (mass.) of light hydrocarbon gases and 0,5 % (mass.) of coke. Fractionation of liquid hydrocarbons allows to separate 15 % (mass) of fraction 340-488 K, 14 % of fraction 406-518 K, 43 % of fraction 438-546 K and 27 % of residue (>623ºС fractions). Liquid products can be applied for production of boiler and furnace fuels independently and in a mixture with the petroleum processing products in different ratio.Документ Oil sludge as source of a valuable carbon raw material(2018) Mardupenko, Aleksey; Grigorov, Andrey; Sinkevich, Irina; Tulskaya, AlenaGeneral trends of recovery of oil sludge into the commodity products are presented below. The technology of concentrating of the carbon part of oil waste was justified. The sequence of processes for refining of sludge into the road and construction bitumen, antiseptic and waterproof materials and lubes was presented as a structural scheme.
