Документ Technological processing of oil waste(2016) Sinkevich, Irina; Grigorov, Andrey; Mardupenko, AlekseySince oil waste is one of the most dangerous component of natural environment, the great attention should be paid for the problem of its keeping and processing. Oil waste may be processed in thermal, physical, chemical and biological ways. Present article describes the processing of oil waste by light thermal cracking. Products of thermal cracking of oil waste, due to their properties, may be widely used in motor oil and other kinds of fuel production.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 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 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.
