Authors: Kurbangaleeva M H , Rizvanova E R , Pergushova L R
Published: April 2020

The analysis of main hazards at the section of isolation and drying of isoprene rubber is carried out. Incident causal factors and scenario analysis were studied and existing measures to ensure industrial safety are reviewed.

The main initiating event of an emergency in the workshop is loss of containment followed by release of significant quantities of hazardous substances with subsequent negative development of the accident.

The measures aimed at reducing the risk of an accident at the facility are: reducing the likelihood of equipment depressurization; minimizing the amount of hazardous substances entering the accident site; localization of the accident site; limitation of time spent by personnel in hazardous areas.

In the event of a power outage, it is proposed to install a diesel generator set of the TSS AD-800S-T400-PM5 brand. This measure allows minimizing the amount of hazardous substances entering the accident site, which leads to a significant decrease in environmental and economic damage from the accident.

Published: April 2020

This paper examines the creation of the hybrid power control system with dense layout of units for the various vehicles. The relevance of the topic is proved by the several publications of Toyota Motors, Subaru Corporation, Texas Instruments and others, who have implemented similar decisions in their electronic control units. The mathematical model and the developed prototype are suitable for gasoline internal combustion engine, where the main feature of this development is the support and control of energy generation. Due to the dense layout of particular vehicles it is necessary to resolve the issues of electromagnetic compatibility, based on protection and decoupling of various elements among themselves. The controlling device for the internal combustion engine of vehicle carries out a complete decoupling of control and signal circuits, and protection of power for integrated circuits. These constructive decisions include the installation of optically decoupled devices, protective diodes and resistances for bypassing the high voltage surges. The proposed concept includes the control of the engine cooling, ignition, engine rate and throttle, generation current, engine startup and cut-off. The prototype working on this concept has an increased uptime and working distance. These features ensure the stability of the engine and its primary characteristics of rate support and generation current control. Processes of installation prototype modeling, technical decisions and reliability issues have been described.

Published: April 2020

The interaction of aromatic amines with piperylene and its chlorine derivatives was being studied. Direct alkylation of aniline by piperylene in the presence of Lewis acids results in its C-substituted derivatives. At reaction of 4-chloro-2-pentene and 3,4-dichloro-2-pentene with arylamines in medium of excess aromatic amine, ring-substituted arylamines are formed due to proceeding Claisen’s amino-rearranging of initially formed N-substituted products. In medium of triethylamine, the same reaction is completed at the stage of N-alkenylation. The compounds obtained are of interest as substances with biological activity; at the same time they are valuable intermediates for the synthesis of nitrogen-containing heterocycles.

Published: April 2020

Magnetic properties, structure, and phase composition of samples of ferruginous rocks from the Zhamanshin meteorite crater have been investigated. X-ray phase analysis, microscopy and magnetometry have revealed that studied rocks can be considered as a fine-grained polymictic sandstone which undergone significant alteration. All samples appear highly ferruginous, with cement of goethite with small particles of the matrix. Detrital grains are quartz, feldspar, rarely mica, as well as monazite, ilmenite, zircon, and cassiterite in accessory quantities. Inclusions of glass, probably of impact origin, with low silica, high alumina, and high iron content have also been encountered. A characteristic feature of goethite is the presence of Mn and a pronounced zonal structure manifesting itself in an increased Al content. Intergrowths and druses of authigenic magnetite are found in voids and cracks; magnetite however appears completely by iron (hydr)oxides. These observations generally agree with the paleogeographic data, and suggest that the crater and its vicinity experienced significant changes of the redox regime in the post-impact time.

Published: April 2020

Electronic waste, or e-waste, is one of the fastest-growing household waste flows. This is due to the raising popularity of electronic devices and ICT in human life coupled with their rapid obsolescence, which means that not only broken, but also fully intact devices quickly become useless. Electronic devices turn into waste while still usable because they no longer meet consumer requirements.
Oscillations of Pipelines Laid on Supports in the Conditions of Aerodynamic Resonance
Authors: Tokarev A , Valeev A , Nurutdinova K
Published: April 2020

Above-ground laying of field and main oil and gas pipelines is one of the most common methods in the conditions of the North and permafrost soils, as well as at the intersection of ravines, canals, small rivers, in rocky soils, in areas of mine workings and landslides. Under the influence of wind, above-ground pipelines can experience oscillations whose frequency is usually equal to the frequency of the fundamental tone of free oscillations. Oscillations occur not only along, but also across the wind flow. The amplitude of oscillations across the flow is greater than the amplitude of vibration along the flow. At certain values of wind speed, the amplitude of oscillations increases sharply. As a rule, when designing, in calculating the distances between the supports, in most cases this phenomenon is not taken into account and the conditions for the occurrence of aerodynamic resonance when the natural frequencies of the pipeline oscillations and the frequency of vortex formation are close are not checked. In the paper the maximum allowable distances between the supports of various above-ground pipelines are determined taking into account the detuning from wind resonance from the condition of a certain critical wind speed.

Authors: Rouvinskaya E , Kurkina O , Giniyatullin A
Published: April 2020

In this paper we analyse data from ESROB (East Sea Real-time Ocean Buoy), namely records of northward and eastward current velocities obtained on 36 horizons (with a step of about 4 m), and records from sensors of CTD on 11 horizons, made from March 20 to March 23, 2016. Graphs of power spectral density and wavelet scalograms indicate the passage of tidal and inertial waves at the sensors installation point. The graphs of the velocity and temperature fields show steeping of the long waves fronts. The described structures have a baroclinic origin, since their vertical structure correlates with the vertical structure of the first baroclinic mode, calculated from the density data for the studied period. However, a sufficiently large interval of data sampling does not allow analyzing the form of short-period internal waves and identifying solitons that are likely to be generated.

Published: April 2020

Analysers for x-ray radiometric testing (X-RRT) are graded by comparing the results with traditional geological testing (GT). This time-consuming operation involves the collection of several hundred tests and their subsequent analysis in the laboratory. The “selection” of the regression equation coefficients between the X-RRT and GT data is complicated by a large range of metal contents and extremely uneven its distribution in the ore zones. For these reasons, the standard deviations between the testing methods are large and vary widely depending on the metal content. To increase the accuracy of regression parameter estimates, it is necessary to enlarge the control sampling. Such method raises the cost of testing and reduces its efficiency at variability of textural and structural features of ores. 270 slime tests of drilling and blasting wells of silver deposit Dukat are used for the analysis. The silver content in the tests according to the assay analysis was from 20 to 10 000 and more g/t. The differences between the main and repeated GT in the intervals of silver content 50 – 239, 240 – 999, 1000 g/t and more were 76, 175 and 651 g/t, respectively. Estimates of the regression equation between the two methods of testing with the help of two algorithms are compared. In the first, the loss function determined by the sum squares residuals (values deviations of the dependent variable from the regression line), in the second – the sum of the absolute values of the residuals normalized by the sum of the values of the dependent and independent variables. As a result, it is shown that in the first case, in order to improve the accuracy of coefficient estimates, it is necessary to exclude observations in which the absolute value of the residuals normalized by their standard deviation exceeds the critical level of 5-7. The second method is resistant to sampling and the number of observations can be reduced by 2 -3 times. Under these conditions, the error of coefficient estimates is close.

Published: April 2020

In the known types of models breaking the ice at contact with the structures of used power approach of the theory of elasticity in which the time factor is not a parameter of stress-strain state of the compressed volume of ice and are not involved in description of its destruction. In the models, the unknown physical criterion of ice fracture is replaced by the pressure at the ice–structure contact boundary as a derivative of the ice strength when testing small samples. This paper, the energy approach is used, which made it possible to show the mechanism of ice destruction as a Converter of the kinetic energy of the ice field into the potential energy of elastic compression of the ice volume and elastic deflection of the structure base. The processes of accumulation of elastic energy in the specific volume of ice, mechanisms of nucleation of foci of destruction and development of cracks, are considered. It is shown that the condition for the onset of destruction is to achieve a critical value of the elastic energy density in a single volume and the specific energy of ice destruction is a regulator of ice load cycles on the structure.

Published: April 2020

A regional economy is greatly dependent on transport. Yakutia spans over 308,342.3 thousand hectares in Russia’s North East. Winters here are long: they last eight months with temperatures down to -50-60°C; summers are short but may be as hot as >30°C. This climate requires special approaches to be livable. This paper dwells upon road transport and its operation. Road transport requires high-quality roads. Today’s road vehicles are high-speed, heavy-duty vehicles; their speed and payload capacity are only expected to rise further. Yakutia’s highways are a set of infrastructures: pavement, earthworks, bridges, pipes, drainage, road signals and signs, recreational areas; pontoon bridges in summer, if necessary. All of that is necessary for road to operate normally. A car road is a costly infrastructure designed to last.

Published: April 2020

In the process of interaction of the man with the habitat he is an integral part of the natural environment. To assess the anthropogenic impact upon the environment, living bioindicators are used which have several advantages over chemical methods of environmental assessment. They can respond even to any minor changes and enable to avoid the use of expensive and labor-intensive physical and chemical methods for measuring biological parameters. The assessment of a degree of soil contamination using bioindication, in places of oil products storage and active contamination from motor transport (central city), enables to determine a soil toxicity. Environmental toxicity can be determined by a level of response of the test object used. Reliability of results is confirmed by environmental statistical methods or biometrics. In this study, we obtained data that, taking into account the geographical location of the sampling point, the results demonstrated both a low toxicity of the soil and a stimulating effect of man-made environmental factors upon its state.

Published: April 2020

The paper examines the variability of the temperature profile (including the generation of its inversion by combined radiant and convective action) for the exposed snow cover, which determines the thermal regime of the underlying medium (dense firn or frozen soils and ground of low- and high-lands) in view of heating by a geothermal thermal influx. Experimental and theoretical researches allowed studying the effects daily radiating-conductive heating inside a snow layer (covered the underlying glaciological mediums) at conditions of the external impact by atmosphere convection (together with longwave thermoradiation) and solar shortwave penetrating thermoradiation. The possibility of the formation of heat conductive fluxes redirected to exposed superficial during subsurface radiant overheating - was shown theoretically in order to prevent thawing of the underlying media. For the first time inversion temperature profiles were registered inside snow thickness on the glacier surface near Elbrus at the height ∼ 4000 m. The authors interpreted this effect from the standpoint of scattering media optics. Snow cover was modeled as a semitransparent medium with volumetric albedo, scattering and absorption indices (coefficients), caused by the calculated parameter of internal radiant heat source function, corrected by the experimentally measured temperature profile of the investigated snow layer. It is shown that during the morning hours at intensive insolation and atmospheric negative temperatures, subsurface overheating inside the glacier is produced. This phenomena was observed experimentally on depth up to 5-40 sm using of thermodes of long measure probe. The obtained results are in the consent with theoretical estimations of authors and foreign researchers.
Experimental and Theoretical Study Focused on Transformation of the Processing Properties of Gold in the Operating Area of a Ball Tube Mill
Authors: Lebedev I F , Osipov D A , Gavriliev D M
Published: April 2020

The article is aimed at studying the process of free gold deformation extracted during grinding in various types of ball mills. Today, ball mills and similar machines are typically used for fine grinding of gold ores. Their working parts include armor plates of a shell, and balls used as grinding media loaded into the shell. Despite the fact that the ball mills dominate over the other fine grinding machines used to extract hard rock gold, they still have serious drawbacks. It is believed that only 2 to 20% of all consumed energy is spent directly on grinding, while the rest of it is used to overcome friction, heat formation, acoustic and mechanical vibrations, etc. In the meantime, mass deformation and degradation of free gold takes place in the mills. The particles degradation has a clearly adverse effect on their further benefication, and their shapes change to various extents as a result of deformation. If the deformation is aimed at forming an isometric shape of particles, their recoverability increases, while the reverse process decreases it.

Published: April 2020

Private property as an institute first emerged in Russia in 1991. State Cadaster appeared as a result to keep land records. Russia’s policy today is to optimize the use and cost-effectiveness of natural resources. Cadaster is the main tool used to generate financial income. The more data is available in the Cadaster, the more profits can be made. The Russian Federation has the world’s largest forest resources. Forested lands account for 70% of Russian land; however, only 20% of the forests is recorded in the State Forest Register, while the rest is still not recorded in the Cadaster. Forest records are kept in the State Forest Register or in the State Cadaster; this duality entails greater costs for those who order and those who perform cadastral surveying. Since forest management does not use the coordinates used by the SFR, recording data on such forest plots is difficult. Forest surveying does not need to be approved by stakeholders, and neither do the boundaries defined by such surveying, as the boundary points are not landmarked.

Establishment of Storm Water Treatment Facilities for Shipyards
Authors: Yakimenko L , Ivanenko N
Published: April 2020

The article demonstrates high level of pollution in the waters and sediments of Ulysses Bay. The pollution can be traced through the sea life vital activity indicators. One of the causes of the negative effects on the bay ecosystem from human use is the lack of storm water treatment by shipyards which operate in the coastal zone and in the waters of Ulysses Bay in Vladivostok (Peter the Great Bay, the Sea of Japan). In this article it has been shown that the organoleptic and chemical indicators for the storm water discharged without treatment into the bay used for fishing activities do not comply to the requirements for storm water quality. The article suggests the design for the storm water treatment facility to be used at the shipyard which was used for the research. The use of the suggested facility – the combined facility for oil and sand interception – would ensure that the amount of pollutants discharged into Ulysses Bay are compliant to the maximum allowable concentration (MAC).
Modelling Atmospheric Properties in Industrial Geodetic Measurements

Published: April 2020

The article considers the questions of studying and modeling atmospheric properties in geodetic measurements on industrial objects near high-temperature aggregates. It is shown that atmospheric properties around such aggregates have significant differences, which influence geodetic measurements. The research was carried out on the basis of an industrial experiment on measuring atmospheric temperature field around a rotation kiln. The mathematical model of the air temperature field in the space around the kiln is divided into two zones: the first one – the space where the total station and sighting marks are positioned; the second one – the space from the shell surface to the distance ≤2.5m. The first zone temperature field is built on measurements made by inhausting thermocouple and interpolation between measurement points by Viner-Kolmogorov filter; the second zone field is built on measurements made on the shell surface by a pyrometer. The research showed that in the direction perpendicular to the aggregate axis the lines of equal temperatures are close to circles. The mathematical model of atmospheric temperatures allows to perform integration of differential equations of the sighting beam between any measurement points, to estimate the values of geodetic refraction, to choose more accurate measurement technology.
Solution of the Problem of Annular Space Gas Utilization in Wells Operated by Walking-Beam Pumping Unit

Published: April 2020

This article presents new approaches to solving one of the problems encountered in many oil fields - the disposal of gas accumulating in the annular space of production wells operated by walking-beam pumping units. This question is relevant because the accumulation of gas and the increase in its pressure affects the depression reduction and the fall of the dynamic level of the liquid, adversely affecting the downhole pumping equipment operation. Critical annular pressure is a value above 10 atm. Traditionally in order to bring the annular gas pressure in line with the linear, reverse wellhead valves installed in the wellhead fittings were used. The use of these valves reduces the annular gas pressure, but does not solve the problem of its subsequent disposal. The emphasis is on the technical and economic efficiency of the proposed associated gas utilization method.

Published: April 2020

This article assesses the prospects for the use of geological and technical measures related to the creation of non-traditional methods. The essence of which is not only high manufacturability, but also energy saving with a significant expansion of geological criteria for their applicability. Hydraulic fracturing is widely used in wells operating an oil reservoir, which in most cases is proved theoretically and practically.

According to the results of geological field analysis, it was found that for the conditions of development of deposits of the Krasnoleninsky field, the introduction of hydraulic fracturing into wells is a tool, the reuse of which, regardless of the current water cut, will help to increase the productivity of production wells. A further increase in the efficiency of work is associated with their complex organization in a reasonable combination of well operating modes, hydraulic fracturing technologies, and optimization of the waterflooding system.

Published: April 2020

The analysis of heat supply in the arctic regions of the Sakha Republic (Yakutia) is given. The Arctic regions include 13 regions of the Republic of Sakha (Yakutia), their territory occupies 52.56% of the entire territory of the republic. The delivery of fuel to the Arctic regions is fraught with large financial costs. They contain 155 sources of heat supply, out of 155 of which 83 work on solid and 72 on liquid fuel. The total fuel demand is estimated at 85.3 thousand tons of fuel equivalent. per year, of which a large proportion, 96%, falls on diesel fuel. To solve the problem of energy supply of the population in the arctic regions of yakutia the role of potential local sources of hydrocarbons is shown. Conducting prospecting and discovery of projected hydrocarbon deposits in the immediate vicinity of potential consumers will significantly optimize the fuel and energy balances of the Arctic and northern regions of the Republic of Sakha (Yakutia). The oil and gas prospectivity of the territory under consideration is shown
Experience in the Remediation of Oil Polluted Soils of the Arctic Zone of Yakutia

Published: April 2020

In the Arctic zone of Yakutia, geochemical studies have been carried out to study the state of the soil in one of the tank farms. The row of informative analytical indicators was used to characterize the composition of oil pollution and assess the features of its biodegradation processes in permafrost soils. The features of the chemical composition of oil pollution in soil samples with a long-term contamination are revealed and are taken into account at developing methods for cleaning soils from “old” oil pollution. An experiment on the biological treatment of soils with a biological product based on indigenous hydrocarbon-oxidizing microorganisms isolated from permofrost soils was conducted. The initial oil content was 34594 mg kg−1. After 3 months of incubation of a biological product, along with a decrease in the residual oil content, the composition of pollution changed in the direction of increasing the content of resin-asphaltene components and decreasing - hydrocarbons. The proportion of oxygen-containing groups and bonds has significantly increased in the chemical structure of alcohol-benzene resin. In the composition of alkane hydrocarbons, a redistribution is established both within the homologous series and between different rows of homologues. The degree of destruction of oil pollution reached 56.6%.
