The main specificity of the operating conditions of control systems lies in their geographical location along the main gas pipelines. As a rule, the facilities in operation are at a considerable distance from the control points, so automation should be used to control several parameters in the gas pipelines. The control of gas contamination is a complex and responsible process, the aim of which is to detect and prevent possible gas leaks that could lead to negative consequences, including fires, explosions and pollution. Continuous air monitoring includes monitoring and analysis of air composition for harmful substances. This makes it possible to quickly determine the presence and concentration of hazardous substances in the air and to take measures to prevent and minimize their impact on workers, as well as to create healthy health and hygiene conditions for staff.The article is devoted to the safety control system, which is designed to provide an automated continuous control over the gas-air medium and parameters of temporary sealing devices during work on the linear part of the main gas pipeline. Its application makes it possible to increase the level of safe working conditions of employees during work on main gas pipelines by reducing the probability of occurrence of accidents and related losses.","PeriodicalId":19570,"journal":{"name":"Oil and Gas Business","volume":"117 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140694189","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}

In order to restore their previous activity and selectivity, as well as extend their service life, a process of catalyst regeneration is carried out. One of the effective methods for restoring the original activity of deactivated catalysts is oxidative regeneration, which is based on the oxidation of coke deposits on the surface of the catalyst.\u0000The article examines the dependences of the formation of surface coke when varying the temperature regime of the process from 450 °C to 550 °C during the thermocatalytic destruction of heavy petroleum feedstock – West Siberian oil fuel oil in the presence of a new metal complex catalytic system, where the active component is a chloroferrate complex (NaFeCl4 or TCFN) in an amount 10 %, deposited on a carrier, which is a deeply decationized Ymmm zeolite of the acidic form (H-form). The patterns of oxidative regeneration of a metal-complex catalytic system were studied by distilling off highly volatile products in a flow of inert gas (helium) and oxygen-containing gas.\u0000During the experiments, it was found that with an increase in the temperature of the thermocatalytic destruction process from 450 °C to 550 °C, a slight increase in coarse deposits on the surface of the catalyst was observed from 2,6 % wt. up to 3,5 % wt. respectively. When carrying out the process of oxidative regeneration of a carbonized catalyst with air oxygen (in a flow of helium) at a temperature of 500 °C for 60 min only volatile components are initially removed, and further calcination takes up to 180 min allows for complete burning of surface coke.","PeriodicalId":19570,"journal":{"name":"Oil and Gas Business","volume":"75 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140261256","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 developed small-sized transportable installation ensures safety, reliability and maintainability in operation with a base capacity of 5,000 t of raw methanol per year. The technological process consists of two main stages: first, synthesis gas is obtained by partial oxidation of the prepared natural gas with air, and then synthesis gas is fed into a multi-reactor cascade of the methanol synthesis complex. The main apparatus of the installation is a domestic three-component (natural gas – air – chemically treated water) synthesis gas generator (SGG), which includes: mixing head, ignition device, combustion chamber, water injection unit, evaporation chamber. The technological complex of synthesis gas with SGG binding is described, the dimensions, parameters and performance of SGG are indicated, data from numerical modeling of partial oxidation of natural gas to obtain nitrogen-ballasted synthesis gas for the synthesis of methanol are presented. A simplified technological complex for the synthesis of methanol has been developed, which includes a direct-flow multi-reactor cascade with the release of raw methanol after each reactor, and numerical modeling of the cascade of synthesis of raw methanol has been carried out. As a result of the research, the degrees of conversion of carbon oxides into methanol were determined, which made it possible to assess the need for application of a three-reactor cascade with a degree of conversion up to 60 % and with a specific capacity of about 800–900 kg/h of raw methanol per 1000 nm3/h of natural gas. Experimental laboratory data are presented, which coincide with the calculations of the material balances of the installation devices.","PeriodicalId":19570,"journal":{"name":"Oil and Gas Business","volume":"134 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140078458","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}

This paper describes in detail the remaining stages of installing the dome: the accumulation of a layer of gas, the final stage of installing the dome, when the tubes for pumping oil and gas are connected to the device and the device begins to work in stationary mode. Let's take a closer look at each of the stages. The fourth stage of the dome installation is associated with the achievement of a given height (at which the gas bubbles have not yet passed into the hydrate state) and the beginning of the migration of gas bubbles inside the dome. First, the gas bubbles migrate into layer of liquid immiscible with water, then in the oil layer. During this process, all the gas coming from the jet completely enters the tank. At the fifth stage, gas accumulations inside the tank are considered. At the sixth stage, the study of the accumulation of layers of gas and oil continues, but at the same time the reservoir itself sinks to the bottom of the reservoir at a constant speed. This is necessary to subsequently secure the dome and prevent oil and gas from leaking out of the dome. The seventh stage is the final one. At this stage, we believe that the dome is fixed on the ocean floor, pipes for pumping oil and gas are connected to it. As a result of the created mathematical model of the dome-separator operation, dependences characterizing the process of installation and functioning of the dome, the temperature dependences of gas and oil layers accumulated inside the dome, as well as the dynamics of accumulation of the corresponding layers in the dome are obtained. The characteristic start and end times of each of the stages are described.","PeriodicalId":19570,"journal":{"name":"Oil and Gas Business","volume":"11 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140261957","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}
