Consumed in the process, the true inhibitor reacts with free radicals and breaks the reaction chain, determining the molecular weight of the polymer. The polymerization moderator reduces the concentration of the most mobile radicals and their lifetime, giving a hydrogen proton to the most reactive free alkyl radical. As a polymerization moderator, dinitrobutylphenol is the most effective, which, according to the degree of exposure to the body, belongs to the first class of danger. The main supplier of dinitrobutylphenol to Russia is the People's Republic of China. The paper considers the possibility of replacing the active styrene polymerization inhibitor with the domestic brand Inflow7007, which is a derivative of para-phenylenediamine. According to the set of characteristics, the new polymerization moderator belongs to moderately dangerous substances of the third hazard class.At the first stage of the work, comparative laboratory studies of four polymerization inhibitors were carried out. The dependence of the inhibitory ability on the concentration of the polymerization moderator, the kinetics of the process was studied, and a comparative analysis of domestic and imported analogues of inhibitory reagents was carried out.Next, an experimental industrial run was conducted at an existing styrene production plant, during which a gradual transition to a domestic inhibitor selected as a result of laboratory research was carried out. The transition was carried out in stages with the gradual replacement of dinitrobutylphenol with an inhibitor of the Inflow 7007 brand. Throughout the entire industrial pilot run, the polymer content in the cubic liquid of the raw styrene separation column was monitored. The conducted studies have shown the high efficiency of the proposed inhibitory system. According to the results of analytical control during the period of pilot tests, it was possible to reduce the average polymer content in the cubic liquid. In addition to increasing the effectiveness of polymerization inhibition in styrene production, the use of the proposed polymerization moderator will solve the problem of import substitution, increase worker safety, and reduce environmental risks.","PeriodicalId":19570,"journal":{"name":"Oil and Gas Business","volume":" 41","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141373916","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 application of energy- and resource-saving technologies to reduce waste emissions into the environment, with the possibility of their partial return to the technological cycle, is an optimal solution for preventing pollution and rational resource utilization. Membrane technologies meet these requirements and are a universal solution for purifying any pollutant with the possibility of its recovery. Moreover, the efficiency of these processes can exceed 99 %, while the equipment occupies less space and uses minimal reagents compared to other apparatus. Based on the above, this study presents research on the separation of hydrocarbon emulsions based on I20-A grade industrial oil using polysulfonamide membranes. To intensify the process and enhance resistance to oil fouling, polymer filters were treated with corona and glow discharge plasma. As a result of this modification, the separation efficiency increased from 80.9 % to 99.0 %, and the productivity increased by approximately 10 times. Analysis of the membranes using electron microscopy revealed surface deformations, such as changes in roughness, due to plasma treatment, leading to improved selectivity towards the water phase of the emulsion. Analysis of the IR spectra showed the most significant differences in absorption bands between the original and plasma-treated polysulfonamide (PSA) membranes in the area of C–O stretching vibrations, contributing to increased water adsorption in the corresponding area. The research results recommend the application of the tested membrane ultrafiltration method for treating wastewater containing emulsified oils, such as used lubricants or cleaning solutions. Plasma treatment of membrane filters with corona or glow discharge contributes to increased efficiency and productivity in emulsion separation.","PeriodicalId":19570,"journal":{"name":"Oil and Gas Business","volume":" 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141375044","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}

Demethanization is based on separation of gas-liquid mixture by low-temperature rectification. The yield and quality of the target gas separation products depend on the demethanizer operation. In this connection it is important to arrange the demethanization unit operation so as to preserve the separation quality in the column and minimize ethane losses with commercial gas. One of the methods of process optimization is the use of technological techniques aimed at reducing the flow rate of gas supplied to the column.This article presents a brief overview of the demethanization process, considers the features of demethanizer operation. Technological solutions of the leading engineering company Linde are analyzed and bottlenecks in the technological scheme are revealed: low depth of ethane recovery, which is associated with high losses of ethane with dry stripped gas; large diameter of the upper part of the demethanizer, which is associated with high loads of the column on the vapor phase. In this connection the optimized technology of the process developed by Research and Design Institute «PEGAZ» LLC is offered. It is shown that application of three-stage separation of gas-liquid streams before their feeding into the demethanizer leads to unexpected results: prevention of possible ethane entrainment, reducing ethane losses, reduction of vapor phase load in the upper part of the demethanizer due to feeding only separation residues into the column as a feed stream. Implementation of such a modified scheme allows increasing the degree of ethane recovery, reducing ethane losses, reducing the mass and dimensional characteristics of the column and its cost.","PeriodicalId":19570,"journal":{"name":"Oil and Gas Business","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141374108","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 highest rates of occupational diseases for 2022 in the Kemerovo region – Kuzbass were recorded at mining enterprises, including coal mining. Particular attention is paid to diseases such as diseases of the respiratory system, musculoskeletal system and eyes. An analysis of the causes of occupational diseases showed that the number of recorded cases in 2022 increased compared to the previous year 2021, and one of the main reasons for their occurrence is the human factor and low safety culture. The importance of introducing a culture of occupational safety in enterprises is to increase productivity, reduce risks and prevent occupational diseases. The importance of the participation of all employees in creating a safety culture is emphasized by reducing incidents in the workplace, as this contributes to the creation of a safe working environment and improves the overall well-being of the workplace, hence reducing the incidence of human error.
