某CNG加气站新建项目安全风险识别与评价研究

本科论文AbstractUnder the circumstance of advocating environmental protection in today's world,gas-powered cars have gradually become the means of transportation for many families,sothe construction and development of CNG filling stations have followed.However,the safetymanagement of CNG filling stations in China is a little weak at present,and the safetyevaluation index system is still in its infancy.Therefore,there are great troubles in the safetymanagement.In recent years,safety accidents have occurred in CNG filling stations fromtime to time,causing considerable losses to people's personal and property.Therefore,inorder to make the construction and development of China's CNG filling stations more stable,it is necessary to study the safety risk identification and qualitative and quantitative evaluationmethods of CNG filling stations.This paper introduces the development and research status ofsafety evaluation methods at home and abroad in detail,analyzes and compares theadvantages and disadvantages of qualitative and quantitative evaluation methods,andconsiders the safety risk identification and evaluation of CNG gas filling station from the riskanalysis and risk factor identification.On this basis,the identification and analysis of riskfactors,the safety checklist method and the risk analysis of operating conditions are adopted,and the identification of major hazard sources is used as the evaluation basis.Finally,the TNTequivalent method is used to simulate the explosion calculation,various safety evaluationmethods are compared,and the evaluation results are used to put forward safetycountermeasures and Suggestions for the weak links in safety management of CNG fillingstation,so as to further improve the safety management level of CNG filling station fillingstation,so as to further improve the safety management level of CNG filling station.Key words:filling station;risk factor identification;safety evaluation;TNT
