ABSTRACT
Currently, the issue of introducing the latest energy-saving technologies in pipeline gas transport is relevant. The problem of incomplete combustion of natural gas in the fire chambers of gas heaters at gas transportation facilities requires special attention. The goal of the work is to develop methods for increasing the efficiency of natural gas combustion and reducing the concentrations of pollutants in emissions of gas-consuming equipment. The article discusses scientific research on the intensification of combustion of hydrocarbon fuels. An easy-to-implement method has been developed to increase the efficiency of natural gas combustion, ensuring minimization of emissions of nitrogen and carbon oxides. The essence of the method is to supply an ozonated oxidizer for combustion. The results obtained can be used in the design of gas heater structures.
KEYWORDS: ozonation, combustion, natural gas, gas heater, emission, combustion products, oxidizer.

ABSTRACT
Technological operations during the manufacture of tanks inevitably lead to the occurrence of residual stresses. Residual welding stresses, which lead to warping of the metal, are especially dangerous. Regulating the heat input during welding will reduce the magnitude of these stresses. Thus, pulsed-arc welding is of scientific interest, which, according to researchers, will reduce the amount of residual welding stresses. The purpose of this work is to study the residual welding stresses of samples made of steel grade 09G2S, welded by multi-pass pulsed-arc welding and direct current welding under specified modes.
KEYWORDS: residual welding stresses, pulsed-arc welding, direct current welding, magnetic anisotropic method, difference in principal mechanical stresses, stress-strain state, non-destructive testing, testing methods.

ABSTRACT
This article is devoted to the issue of efficiency of application of fibre-optic leak detection systems for identification of small leaks on trunk pipelines. The main methods of leakage detection currently in use have been considered, and parametric and fibre-optic LDS have been selected for comparison analysis. In the course of the research, a model of product leakage from an underground oil pipeline equipped with a fibre-optic LDS was built in the COMSOL Multiphysics software package. The result of the simulation was the estimated time of leak identification by the fibre-optic system, which turned out to be much shorter than that of the parametric LDS. Compensable environmental damage for each type of system was then calculated, confirming the effectiveness of fibre optic LDS for detecting small leaks on trunk pipelines due to the significant reduction in compensable damage.
KEYWORDS: fibre-optic LDS, parametric LDS, leakage, modelling, underground oil pipeline.

ABSTRACT
The paper considers the causes of vibration and ways to reduce it for vertical booster pumping units. On the basis of experimental data and mathematical modeling, it has been established that the circulating frequency of the upgraded pumping unit NPV 3600-90-M in the case under consideration is in resonance with the natural frequency of the «engine - support structure» system, which is the above-ground part of the equipment under consideration. At the same time, it was taken into account that the turnover frequency of the upgraded vertical booster pump differs from the turnover frequency of the “classic” version. Taking into account unacceptable limits of ratio of natural and exciting frequencies, optimal range of natural frequency of above-ground part of pump unit is determined. As a method of detuning from resonance, an increase in the rigidity of the system under consideration due to an increase in the wall thickness of the above-ground part of the supporting structure is considered.

ABSTRACT
The article discusses the existing methods and criteria for evaluating the efficiency of turbo-expander units (TEU) at gas cooling stations (GCS) located at gas treatment plants. It was found that at the moment there are no methods and criteria in the regulatory and technical documentation that allow evaluating the energy efficiency of TEU as part of a gas cooling station. A large selection of performance indicators presented by different authors may lead to a distortion of the integral assessment of the work of the TEU as part of the GCS. The review and analysis of existing methods and criteria presented in the article can become the basis for the development of a methodological approach to evaluating the efficiency of turbo-expander units as part of gas cooling stations.
KEYWORDS: turbo-expander unit, gas treatment plants, methods of energy efficiency assessment, gas cooling station.

ABSTRACT
In connection with the emergence of a spiral-wound method for installing tanks for storing oil and petroleum products and the lack of a regulatory and technical framework for the design and assessment of the residual life of this type of tank, there is a need to create an approach to assessing its life according to the criterion of cyclic loading. The article presents a numerical model of a spiral-wound type tank with a volume of 10,000 m3; for various tank wall thicknesses, equivalent Von Mises stresses were calculated using the finite element method in the ANSYS environment. Based on the results of calculating the stress-strain state, the strength and stability of the tank wall was assessed in accordance with existing standards. Wall thicknesses from 5 to 12 mm satisfy all requirements. As a result of approximation based on modeling data, the dependence of the wall deformation on its thickness along the height was obtained, as well as the dependence of the equivalent Von Mises stresses in the wall of a spiral-wound type tank on its thickness along the height of the tank. An approach is proposed to assess the residual life of a spiral-wound reservoir based on the criterion of cyclic loading based on numerical modeling.
KEYWORDS: vertical steel tank, residual life assessment, stressed-deformed state, finite-element theory, hoop stress, cyclic loading.

ABSTRACT
The work is devoted to the dynamics of a two-stroke single-cylinder engine. Such an engine is promising from the point of view of the high efficiency of the engine. Its main drawback is its imbalance. In this paper, a new scheme of the crank mechanism of a two-stroke single-cylinder engine is proposed. Between the strut and the crank there is an elastic hinge with a given angular characteristic. The work proves the possibility of obtaining a constant angular velocity of the crank of a two-stroke single-cylinder engine. An elastic hinge is a structure in which a pneumatic spring moves between circular guides of a calculated shape, resulting in a given hinge characteristic. The characteristic is calculated in such a way that when added to the existing characteristic of a known engine, an “ideal” characteristic of the considered engine with an elastic hinge is obtained, at which the angular velocity of the crank will be constant. When changing the angular velocity of the crank, a different characteristic of the hinge is required. It turned out that by changing the excess pressure in the pneumatic spring it is possible to compensate for the change in the characteristics of the hinge required for a constant angular velocity of the crank.
KEYWORDS: Two-stroke single-cylinder engine, elastic hinge with a given characteristic, pneumatic spring, crank mechanism.

ABSTRACT
The article presents a methodology for the derivation of equations that can later be used to calculate the flow rate of a gas-air mixture through a tank breathing valve in the atomic mode Q(ΔP, h). Step-by-step techniques for the CBV-1500 line are described, which can be extended to the search for the dependence Q(ΔP, h) for other modifications of breathing valves. The formulas for the flow rate of the gas-air mixture for a fully open pressure plate and half for CBV-1500/150/250/500 have been selected. The equations were selected as a result of statistical analysis of the following OLS regressions: linear, polynomial, of the form Z = a•x + b•y and of the form Z = a•x•y. The methodology of the proposed system of automatic accounting of hydrocarbons released as a result of working and standing is described.
KEYWORDS: evaporation losses, standing losses, working losses, vertical tank, light hydrocarbon fractions, natural losses.

ABSTRACT
The article describes rheological properties of heavy oils, relevance of the existing method for calculating the densities of heavy oils in accordance with the Interstate standard. The authors conducted experiments on seven samples of heavy oils to study their densities and viscosities, changes in rheological properties with growing heating temperatures of oils to increase the efficiency of pipeline transport of heavy oils. The viscosity of heavy oils was measured using a Brookfield rotational viscometer. Density was measured with an Anton Paar density meter, which measures density using an oscillating U-shaped sensor over any viscosity range. Based on experimental data, the coefficients of thermal expansion were calculated. The authors revealed a deviation of the standard the coefficients of thermal expansion from those obtained as a result of the experiment.

ABSTRACT
This article is devoted to assessing the hydraulic features of viscous oil flow in the presence of moderate surface heating near the pipeline wall. During the study, a model of a viscous oil pipeline was built in the ANSYS FLUENT software package to compare changes in the velocity profile with and without surface heating. The temperature distribution in the near-wall layer is shown at a pipe wall temperature of 80 °C. The results of the dependence of the hydraulic slope on the average flow temperature for uniform and surface heating are presented. An assessment was made of the possibility of using surface heating near the pipeline wall to reduce energy costs when pumping oil. The maximum percentage value of the reduction in hydraulic losses during surface heating of the near-wall layer of oil was revealed, taking into account restrictions on the heating temperature.

ABSTRACT
One of the main parameters on which the performance and resource of the gas pumping unit depends is the quality and stability of the characteristics of the lubricating oil. Therefore, special attention should be paid to the cleaning process and the operating conditions of the lubrication system. Reducing oil consumption, in turn, helps to save resources, allowing you to reduce the cost of maintaining the unit’s operability. These tasks are interrelated, and they need to be solved comprehensively. This article will consider several technological solutions implemented at the “Severnaya” compressor station of the Northern line pipe operation center, which is a branch of “Gazprom Transgaz St. Petersburg” LLC, which significantly reduced the specific lubricating oil consumption, improved its quality and maintained it for a long time.

ABSTRACT
The paper considers existing models for calculating integral physical parameters of a heterogeneous medium containing spherical inclusions that affect the distribution of electric field strength. These are the formulas of Maxwell, Bruggeman, Lichtenecker, Rayleigh, Betcher, Lorentz-Lorentz and others, applied separately in each specific case depending on the type of heterogeneous medium (for example, in the presence of spherical, cylindrical inclusions or multilayer media), as well as depending on the distance of inclusions from each other and the ratio of medium conductivity. To determine the conductivity and electrical resistance of the soil as a statistical mixture, formulas for two-component or multicomponent media can be used, for example, the K. Lichtenecker formula, which works for inverse electrical resistivity values. To estimate the integral value of the electrical resistivity of an inhomogeneous soil, taken into account when calculating the electrochemical protection of pipelines of site structures under conditions of cathodic current shielding, a mathematical model with a certain range of practically significant parameters and volume concentration ratios was experimentally obtained.
KEYWORDS: electrochemical protection, industrial sites, shielding of cathodic protection currents, electrical resistivity of heterogeneous soil, volume concentration ratio, modeling of heterogeneity of soil conditions.

ABSTRACT
The article deals with issues related to the influence of physical characteristics of sulfite liquors and their concentrates on the parameters of pumping equipment. The methods of liquor and lignosulfonate production are considered, which consist in the treatment of prepared wood with cooking solution, the composition of which depends on the cooking method. The process of lignosulfonate production is studied. Sulfite liquor (lignosulfonate), which is, in fact, a production waste, has a wide range of applications in various industries. The comparison of the main indicators of the pump at moving of technological liquids obtained by delignification of wood is made. It is established that there is a difference in operating conditions and required parameters of the pumps used for pumping sulfite liquor and lignosulfonate. On the basis of production data it is shown what is the effect of viscosity and density of sulfite liquors and their concentrates on the performance of pumping equipment. Some aspects of the influence of physical characteristics of sulfite liquors and their concentrates on the transport processes in the production cycle of chemical processing of natural wood polymers are investigated.
KEYWORDS: sulfite liquor, lignosulfonate, pumping equipment, pump characteristics, viscosity, density, pumping.
