The article analyzes the possibility of determining the degree of soil contamination with hydrocarbons by assessing the chlorophyll content in the plant. The problem of joint assessment of soil pollution based on the chlorophyll content in the leaves and crowns of plants has been formulated and solved. Formulas were obtained for calculating the total content of petroleum hydrocarbons depending on the amount of chlorophyll in the leaves and crown of the plant, as well as for calculating the unevenness of soil pollution between two given points of the soil covered with plants.

This article examines the problem of introducing a standard for the quality of measurements of petroleum products coming out of a well in production. The aim of the work is to develop a solution to improve the accuracy of the measurement information obtained from piezoelectric sensors of vortex flowmeters using methods of software processing of the results. In accordance with the aim the following tasks were set: to analyze existing methods for oil and gas flow measuring, to analyze methods for digital processing and filtering signals from the sensor element of the vortex flowmeter, to classify the interference of the output signal from the sensor, to develop models for changing the interference of the signal from the vortex flowmeter, to develop a software solution for an interference filtering algorithm using fast Fourier transform for vortex flowmetersIt has been proven that as a criterion for excluding the self-propelled phenomenon of a vortex flowmeter, a threshold amplitude level can be taken, which does not allow flow measurement to be carried out until a certain signal amplitude level is reached.It has been established that the use of digital signal processing methods using an analog-to-digital converter can significantly reduce the influence of interference and increase the accuracy and reliability of measurements using digital filters and spectral analysis based on the Fourier transform, as well as avoiding the self-propelling phenomenon during operation due to the threshold amplitude level.Criteria have been established for determining interference, according to which the classification of interference has been compiled. It is also determined that the signal with the largest amplitude is the useful signal.

A centrifugal pump rotor is proposed with the impeller mounted on the shaft using two nuts of fixed interacting reciprocal conical surfaces. The scientific work relates to the field of pump engineering, namely, to one of the methods of locking the rotor nut used in the design of centrifugal pumps, various self-locking devices of mechanisms and structural elements of fasteners that prevent self-unscrewing. The self-locking nut includes a nut, a solid crown with an inner conical surface interacting with the annular groove of the nut itself and with an annular conical groove on the outer surface and, moreover, on one side of the annular groove of the nut itself with a conical outer surface, and the inner conical surface of solid crown is conjugated with the outer conical surface of the nut itself. The inner conical surfaces of the solid crown are connected to the outer ones – the nut with tension.

Cast asphalt concrete has a number of unique advantages, among which the increase in density without additional compaction is especially appreciated. However, for cast asphalt concrete production, a special asphalt binder is used, consisting of an increased proportion of bitumen and mineral powder, which greatly increases the cost of the finished coating.The authors conducted studies to study the effect of fine petroleum coke residue of the visbreaking process (visbreaking residue) and synthetic wax on the quality of cast and polymer-asphalt concrete mixtures.In the course of the research, an alternative bitumen-mineral composition based on finely dispersed coke modified as an oil binder was prepared, and synthetic wax was used as a plasticizing additive.As a result of the tests, inexpensive and effective cast and polymer-asphalt concrete mixtures with improved thermal properties, mobility and, at the same time, aimed at solving environmental problems due to the utilization of coke fines and its dusty fraction, were obtained.

The effectiveness of the Company largely depends on the professional skills of employees, but even more so on the organization of business processes, including production ones. If the processes in the organization are not built or built, but not correctly, then employees will face constant obstacles in solving problems in connection with which their productivity and the efficiency of the process as a whole will decrease.The article presents the results of the project for the development of a continuous improvement system at OC Kondaneft JSC using lean manufacturing tools and process approach methods that made it possible to reduce costs and increase the efficiency of production processes.

Underground pipelines operating experience shows that their operating life and reliability largely depend on effectiveness of metal corrosion protection, both internal and external surfaces. In the latter case, along with electrochemical protection, insulation coatings play an important role. In recent years, there has been a trend to use factory-insulated pipes. Its advantages are obvious: high-quality preparation of pipe surface, strict control over compliance with the technological mode of application. However, in some cases it is impossible to do without field coating: during overhaul, diagnostic works on the linear part and process pipelines of pumping stations. In this case, it is relevant the improvement of insulation materials and field coating technologies.The aim of this work was to study the influence of the component composition of bituminous-polymeric and asmolic mastics on their adhesion to the pipe metal and the operational characteristics of the insulating materials. In doing so, the following tasks were solved:A specially developed gravimetric technique to study the interaction of asmol with the metal surface was used. The cover films formed in this process were studied using an electron microscope at a 1000× magnification.It has been shown that when applying asmol coating, its functional groups enter into chemical interaction with the compounds formed on pipe surface. An indirect confirmation of this is an absolute resistance of the asmol coating to repeated flushing with solvents and water. This peculiarity is not observed in the case of bituminous-polymeric coatings: bituminous-polymeric mastic is completely washed off the surface of steel in a similar treatment.Calculating of the «reduced» cost of 1 km of pipeline re-insulation has revealed a significant advantage of asmol-mastic coating over the bituminous-polymeric one from the economic point of view, since the former not only provides a better adherence to the pipe surface, but also achieves significant savings, since a smaller thickness of the protective coating is required.

Due to the high demand for wood as a building material, there are many ways to improve its strength, physical and other characteristics. One of the most important factors in the sphere of fire and industrial safety of facilities in which wood materials are used is the study of increasing the fire resistance of this material. The most effective ways to improve the fire protection of wood are surface treatment with fire-retardant paints and enamels, as well as impregnation of the inner layers of wood with special compounds. The purpose of the work is to study the impregnation of wood with Pirotex, to analyze the effect of the immersion time of wood in a fire retardant composition on burning behavior and afterglow time. In the course of the studies, the average values of the first flash, afterglow duration and the combustion initiation, depending on the time of impregnation, expressed in seconds, were established. Based on these data, it is possible to interpret the conclusion about the need for wood impregnation for a certain amount of time. The result of the experiments carried out is the establishment of the most effective range of wood impregnation time. Based on the results obtained, it was found that the most qualitative result is obtained by impregnation from 8 to 24 h at a temperature of 26 ± 1 °С.
