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.","PeriodicalId":19570,"journal":{"name":"Oil and Gas Business","volume":"151 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140693657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":19570,"journal":{"name":"Oil and Gas Business","volume":"132 s1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140693560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":19570,"journal":{"name":"Oil and Gas Business","volume":" 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140692392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":19570,"journal":{"name":"Oil and Gas Business","volume":"124 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140694394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.","PeriodicalId":19570,"journal":{"name":"Oil and Gas Business","volume":"13 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140693257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
