The relevance of this article is related to the mandatory training in labor protection to meet the qualifications of specialists. The scientific article highlights the problem of the ineffectiveness of occupational safety training, focused exclusively on theoretical knowledge without a practical component. Lack of practice limits the application of theoretical knowledge in real situations, which leads to insufficient safety in the workplace. The relevance of the article is emphasized by the mandatory nature of occupational safety training and its importance for improving working conditions. Cross-disciplinary training is proposed as a solution to the problem, facilitating the exchange of experience, improving communication and developing collective skills. For optimal results in the field of occupational safety, it is proposed to develop cross-disciplinary training programs with a practical component.Program of additional professional education «Occupational Safety and Health. Workshop», developed jointly by the Federal State Budgetary Educational Institution of Higher Education «Ufa State Petroleum Technical University» and PJSC «Gazprom Neft», is a practical step in solving the identified problems. Analysis of the results, study of standards and interviews with the target audience of the training made it possible to create a program aimed at developing not only theoretical, but also practical skills necessary to ensure safety in the workplace.As a result, the implementation of such programs will be a key step in improving the skills of workers, ensuring occupational safety and minimizing the risk of accidents at work. The transition to cross-disciplinary training in occupational safety and health is a vector for further research and development, which is important not only from a practical, but also from a socio-economic point of view.

The possibility of utilizing native waste from drinking water treatment as an absorbent material for petroleum products (motor oil grade 5W-40, diesel fuel, gasoline grade A-92) has been investigated. The mineralogical composition of the water treatment waste has been determined, according to the results, it primarily consists of quartz, calcite, sepiolite, anorthite, and gallwazite. Values of the maximum absorption capacity for the investigated petroleum products and the maximum water absorption have been established. To reduce water absorption properties, the native material have been modified by thermal treatment at a temperature of 550 °C, treatment with 5 % solutions of sulfuric acid and sodium hydroxide, as well as a 5 % solution of silicone fluid of the «Ecodom Bio» brand. Values of the maximum absorption capacity of the modified water treatment waste for petroleum products and water under static and dynamic conditions also have been determined. It has been revealed that thermal treatment contributes to achieving maximum absorption capacity values for both petroleum products and water absorption. It has been established that the minimal water absorption is observed in the sample of the investigated material treated with a siliconorganic fluid solution. Purification of liquids containing hydrocarbons at a concentration of 2 mg/dm3 in dynamic conditions has been carried out. Overall, it has been determined that the maximum solution purification is observed for motor oil, and the minimal one – for gasoline grade A-92.
研究了利用饮用水处理产生的本地废物作为石油产品（5W-40 号机油、柴油、A-92 号汽油）吸附材料的可能性。根据研究结果，水处理废料的矿物成分主要由石英、方解石、海泡石、阳起石和五倍子石组成。确定了所调查石油产品的最大吸收能力值和最大吸水率。为了降低吸水性能，对原生材料进行了改良，包括在 550 °C 的温度下进行热处理、用 5% 的硫酸和氢氧化钠溶液以及 5% 的 "Ecodom Bio "品牌硅油溶液进行处理。此外，还确定了改良水处理废料在静态和动态条件下对石油产品和水的最大吸收能力值。结果表明，热处理有助于实现石油产品和水吸收的最大吸收能力值。经证实，用硅有机流体溶液处理过的调查材料样品的吸水性最小。在动态条件下，对浓度为 2 mg/dm3 的含碳氢化合物液体进行了净化。总的来说，机油的溶液净化效果最好，而 A-92 号汽油的净化效果最差。

A significant part of the installations of oil refineries are hazardous production facilities and are characterized by the presence of a large amount of flammable substances that can form explosive mixtures with air. One of such units is a delayed coking unit (DCO). The ultrasonic treatment plant plays an important role as part of a refinery, increasing the depth of oil refining (up to 98%) and contributing to the production (along with coke) of large volumes of light oil products and gas. The action of a number of dangerous factors can lead to depressurization/destruction of equipment, as well as to the failure of flange connections of devices and pipelines, seals of pumps and fittings, and to the release of hazardous substances. The article provides information about a number of registered accidents that occurred at ultrasonic testing facilities in Russia, as well as their causes. In the analyzed cases, there were human errors. Particular attention should be paid to the training of ultrasonic testing operators, on whose actions the stable functioning of the technological process depends. The plant operator must be actively involved in the management of the production cycle, which requires a thorough understanding of not only how the plant operates, but also the ability to anticipate potential problems and respond in a timely manner to problems that arise. Often, classical methods of training personnel for emergency situations show insufficient effectiveness, so the solution to the problem is seen in strengthening the rules of industrial safety when working at ultrasonic testing facilities, and practicing skills through training on specialized computer simulators. To date, there is no information in open sources on simulators specifically for delayed coking units. The authors considered aspects of the formation of the technical specifications and architecture of the simulator for ultrasonic testing operators with an emphasis on industrial safety and response during an emergency. A block diagram of a virtual training complex for ultrasonic testing has been proposed.

Currently in the oil and gas industry, the most common is the underground pipeline laying. Underground pipeline laying is also used in water-saturated soils. When water-saturated soil freezes, due to ice expansion, a force acts on the pipeline outer surface. This force leads to the appearance of compressive hoop stress in the pipeline wall and can lead to the pipe wall stability loss. For various reasons, there may be water in the cavity of an underground pipeline laid in water-saturated soil. Due to negative temperatures and water-saturated soil freezing, ice will be formed in the soil, as well as in pipeline cavity. In this case, the expansion force of ice in pipeline cavity creates internal pressure on the pipe, alongside with a ring tensile stress. The expansion force of ice in the soil creates external pressure on the pipe with the occurrence of hoop compressive stress. The need to ensure environmental safety of pipeline system operation in the oil and gas industry involves assessing the strength of an underground pipeline laid in water-saturated soil and containing water in the pipe cavity under the influence of ice expansion forces.The aim of research: ensuring environmental safety based on assessing the strength and stability of the pipeline wall due to ice expansion forces.Object of research: environmental safety, pipeline or its sections under the influence of ice expansion forces.Research methods: theoretical studies of the stress-strain state of pipelines in water-saturated soil containing water in the pipe cavity during the onset of sub-zero temperatures, when the pipes are exposed to external and internal ice expansion forces.Analytical expressions are obtained to determine the pressure on the surface of a pipeline laid in water-saturated soil and containing water in the cavity due to ice formation in the soil and in the pipe cavity.

Catalytic gas oil has been investigated as a raw material for producing an environmentally friendly petroleum plasticizer of the base of gear oil. An oil plasticizer for automobile tires and an oil base for gear oil were obtained by cleaning gas oil by catalytic cracking, a multifunctional catalyst complex (MСC) from polycyclic aromatic hydrocarbons and organosulfur compounds. From raffinate after purification of catalytic gas oil, an environmentally friendly petroleum plasticizer for modern automobile tires was obtained. An oil base for a gear oil with high tribological characteristics was obtained from the oil fraction 390–440 °C with a high sulfur content obtained during the regeneration of spent MСС with a mixed solvent, after oxidation with hydrogen peroxide in the presence of rapeseed oil. Tests of the physico-chemical properties of the petroleum plasticizer were carried out according to GOST 1138, and tribological characteristics of the oil base and gear oil were tested according to GOST 9490.

Experiments for treating soil contaminated with oil and petroleum products using electric current in laboratory conditions using graphite and ruthenium titanium electrodes were carried out. The main purpose of the study was to study the dynamics of temperature changes during soil treating. The obtained and analyzed results allowed us to draw conclusions about the influence of various factors on the soil treating and the efficiency of using graphite and ruthenium titanium electrodes. The greatest resistance is observed in the central zone of the electrochemical cell. Closer to the electrodes, the resistance decreases, which contributes to a more efficient electrochemical treating process in these areas. Modern methods of data analysis, including statistical analysis and visualization of results, were used in the work, which made it possible to obtain more accurate and reliable results and draw conclusions about the possibility of using this technology for practical purposes.

Oil and gas equipment is operated in very difficult conditions. The reliability and durability of equipment depends on the technical and economic characteristics of structural materials. They are subject to very strict conditions. High demands are placed on the corrosion resistance of structural materials. The service life of metal structures in aggressive and hazardous environments is relatively short due to irreversible corrosion processes of metal equipment. Without the use of special chemical reagents, long-term operation of equipment in the oil and gas industries is impossible. The rapid development of these industries indicates a high demand for these reagents. General methods of combating the physical and chemical destruction of metals include the use of corrosion-resistant metals such as chromium and zinc as protective coatings, alloying of metals, the use of paints and varnishes, as well as special corrosion-resistant products when creating equipment, electrochemical protection, etc. A common method of protection is the use of inhibitors. They provide a reduction in the rate of corrosion process in metals in contact with various aggressive environments. To date, a fairly large number of organic and inorganic substances have been studied that influence the rate of the corrosion process in metals. Organic inhibitors are widely used because they are capable of forming stable protective films on the surface of metals. Highly effective inhibitors of organic origin mainly include substances containing heteroatoms. In this article, based on modern literature data from research by various authors, the task is to identify the most appropriate methods of combating corrosion. The principles of corrosion protection are considered, which made it possible to develop basic provisions for the organization and technology of using heteroorganic inhibitors, taking into account the aggressive effects of corrosive components.

The problem of shaping the image of a mixer in a synthesis gas production complex depending on productivity is discussed in the article. The main task is to justify the choice of a structural element for effective mixing of components in a small-scale synthesis gas production complex with a productivity of up to 5000 tons per year. Optimal conditions for each unit of the complex are being developed in order to ensure the quality performance of the individual block and to change the appearance of the mixing formation unit. The concept of creating mobile, transportable small-scale methanol production complexes, providing the necessary amount of product directly at the extraction site is discussed in the paper. The following requirements for these complexes are considered: mobility, transportability, work reliability in extreme conditions, small size, integration into infrastructure, maximum automation. In the context of this study, the processes of mixing components in the mixer, which allows us to define the quality picture of component mixing, overall dimensions, and appearance of the node itself are evaluated. Detailed analysis of the mixing processes in the mixer is carried out and its structure and functions are studied in depth. The paper presents a detailed analysis of the scheme, performed by iterative calculation of each element in the block under certain conditions and restrictions. The results help to identify the influence of productivity on the complex as a whole and on a specific node. This study will help specialists better understand optimal design and operation strategies for mixers for the production of synthesis gas. The article deepens the understanding of structural analysis in the context of choosing the most suitable structural element for effective component mixing.

The polymer industry in Russia is one of the most promising industries predisposing to economic development. There is increasing interest in so-called high-performance plastics, which have a list of constructive and technological properties, the key of which is high temperature stability. Among these, it is worth highlighting polyetheretherketone (PEEK), one of the most expensive polymers, the cost of which is due not only to high-temperature stability, but also to mechanical and good electrical insulating properties, resistance to β-, γ-, X-ray and infrared radiation, to chemical influences and etc.This paper reviews the properties of PEEK and the demand for it on the market today. A comparative analysis of currently existing methods of its production was carried out. The most promising synthesis method for industrial implementation and its features have been studied.This material can be used to construct a calculation technological scheme for the synthesis of polyetheretherketone.

In modern construction, increasing attention is paid to the search for new materials and technologies that can improve the properties of concrete mixtures. Chemical additives such as superplasticizers and air bubbles are used to improve the workability of the concrete mixture and increase its plasticity. The strength characteristics of concrete mixtures are an important criterion in solving issues related to the profitability of the construction process. The use of plasticizers and hardening accelerators makes it possible to obtain high-strength mixtures with unique characteristics and guarantee high quality construction. Lignosulfonate-based additives have unique properties that can significantly increase the plasticizing characteristics of a concrete mixture. Tests for strength, frost resistance, resistance to aggressive environments, bending and torsion make it possible to evaluate the properties of concrete with lignosulfonate-based additives.While researching, several samples of concrete mixtures with different compositions were prepared. In the experimental testing laboratory, under conditions close to production conditions, a series of experiments was carried out with samples of concrete mixtures for compliance with the requirements of regulatory documents for concrete quality: a lignosulfonate-based additive with concentrations 0.5 %, 1 %, 1.5 % was added to the concrete mixture of compressive strength class B15 to volume 2286 kg/m3.It has been established that the use of a product of natural polymer chemical processing – lignosulfonate – improves the plasticizing properties of concrete mixtures with a two to fivefold increase in mobility and without slowing down the hardening of concrete both in the early (3 days) and late (10–15 days) periods of hardening.It has been revealed that the use of an additive based on lignosulfonate helps to increase the strength of concrete by 25–30 % compared to known plasticizing additives.It has been calculated that the use of a lignosulfonate-based additive helps to reduce cement consumption by 12–15 %.It has been shown that the addition of 1 % lignosulfonate reduces water absorption by 9 % and increases the average strength over 7 days by 10 %, which makes it possible to use the practical results of the research to develop new concrete compositions with improved technical characteristics.
