某LNG加气站新建项目安全风险识别与评价研究

本科论文AbstractIn recent years,LNG energy has been used more and more widely in our country,andLNG is also developing at a high speed.The construction of CNG and LNG comprehensivefilling stations is also widespread,and the state has relevant encouraging policies.In the useprocess,the gas filling station also always has great potential risks,such as fire,explosion andother major risks.Although with the development of science and technology,the possibility ofoccurrence of danger under strict control is very small,if an accident really occurs for somereason,the accident is disastrous.For possible accidents,we should pay attention to the safetyhazard identification and safety evaluation of gas filling stations.In this paper,the basic situation of LNG filling station is understood,and the equipment,facilities and important process flow in the filling station are understood.On this basis,thesafety hazard identification of the filling station is carried out.Through studying and selectingthe safety evaluation method suitable for this article,the safety overall evaluation research iscarried out.Qualitative and quantitative safety parity research is carried out according tohazard source identification in the gas filling station,and the death radius,minor injury radius,serious injury radius and property loss radius of explosion after partial LNG leakage arecalculated through quantitative research using TNT equivalent.And put forward thecorresponding safety measures.Key words:LNG:LNG filling station;Hazard sources;Identification;Safety evaluation
