某公司新建工业气体分罐充装站项目安全风险识别与评价研究

本科论文AbstractOxygen,nitrogen,argon,carbon dioxide and mixed gases are dangerous for explosionand poisoning,so improper operation in production and use will cause serious consequences.Improper operation during production and use will cause serious consequences.Because thestorage of oxygen,nitrogen,argon,carbon dioxide and mixed gas is mostly stored in storagetanks,the storage capacity is huge.When the tank leaks,the oxygen,nitrogen,argon,carbondioxide and mixed gas are in ultra-low temperature liquid state are encountered The ultra-lowtemperature oxygen,nitrogen,argon,carbon dioxide and mixed gas in normal temperatureenvironment will become classifier at normal temperature,while the gaseous oxygen,nitrogen,argon,carbon dioxide and mixed gas will follow the wave and move in the air dueto its explosion.risk.In case of ignition source,combustion and explosion accidents are easyto occur,causing extremely serious unnecessary casualties and property losses.Therefore,inorder to prevent accidents caused by leakage of oxygen,nitrogen,argon,carbon dioxide andmixed gas,the leakage diffusion of oxygen,nitrogen,argon,carbon dioxide and mixed gasstorage tanks is analyzed to find out the causes and analysis of the leakage accidents Theseverity of the consequences is extremely important for predicting the consequences ofaccidents and preventing them.This study is based on the research and storage of distribution tanks for oxygen,nitrogen,argon,carbon dioxide and mixed gas tanks in the new industrial gas filling station,as well asthe storage of oxygen,nitrogen,argon,carbon dioxide and mixed gas tanks.The process ofleakage and diffusion in the filling process is studied,and the law of leakage and diffusion issummarized,and the preventive measures under the law are summarized.Keywords:gas sub-tank filling:leakage;diffusion;prevention
