Additives have been identified that are used in a number of refineries, such as a passivator, coke inhibitor, dispersant, corrosion inhibitor, neutralizer, defoamer or antifoaming agent. The most vulnerable points of the visbreaking installation technology are considered. A diagram is presented with the designation of areas with possible problems, namely foaming of the oil product, contamination by coke deposits of equipment, corrosion of helmet lines, the possible formation of hydrogen sulfide and other undesirable components. A comprehensive review of each reagent allows you to understand its purpose at the facility, to understand the mechanisms of the action of reagents. The approximate compositions of each reagent are analyzed, the requirements for additives are considered.","PeriodicalId":488692,"journal":{"name":"Tehnologii nefti i gaza","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135843172","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 method used in this article is a mathematical analysis of the dependenciesof the efficiency of drag-reducing agent in pipelines of different diameters with different roughness of the pipeline wall.This article analyzes the dependencies for calculating the coefficient of hydraulic resistance during flow in pipelines of various diameters. The dependence of the hydraulic efficiency of the drag-reducing agent on the diameterof the pipeline is analyzed.
