Research On Safety Risk Assessment In JiLin City CNG Filling Station

Under the national energy policies to guide environmental protection in recentyears the national natural gas car ownership and gas filling stations the numbercontinues to grow. However, due to the gas filling station safety managementtechnology research lag in our country, gas filling stations safety problemincreasingly protruding. Natural gas vehicle industry in China in order to ensure thehealthy and sustainable development, study of gas filling stations safety issues arevery important in theory and reality significance.In this paper the author mainly from the angle of construction and operation ofnatural gas filling station starts, the system will be divided into evaluated the safetyevaluation of different types of units, using the vapor cloud explosion damage radiusmodel method, risk evaluation, risk classification method, comprehensive method, bycombining the theory with the practice of actual production operation mode thestation is analyzed, and on this basis, established the calculation model of natural gasfilling station safety index and safety risk assessment. Security risk assessment inJilin City, gas filling station as an example of this paper, it is discussed and analyzedfrom theory and practice. Effectively this research will promote China’s gas fillingstation safety risk assessment work.As gas filling stations in ever increasing Numbers, radiation region growing,security have been the social attention. Gas filling stations belong to the yi anexplosion and fire dangerous sites, in the event of accident, not easy to control, andthe influence is bigger, to evaluate the safety of the gas filling stations and studies thesafety management, is has important practical significance of the topic. This topic of Jilin gas filling mother station run fully understand the situation, the Jilin city gasfilling station security risk evaluation system, specific content as follows:The first chapter introduction, this paper analyzes the thesis research background,research purpose and significance, research status at home and abroad and theresearch content. Affirm to the development of gas filling stations, in security riskassessment is put forward question. Study of Jilin gas filling station security risks, toJilin building the clean city has certain reference significance.Chapter2Jilin gas filling mother station safety risk identification, discusses indetail the basic situation of Jilin City gas filling station, analysis of the gas fillingstation to the economic environment and market demand; and introduces theconstruction contents, focuses on the confirmation dangerous factor identification andmajor hazard safety risk.Chapter3Jilin gas filling mother station security risk evaluation index systemestablished, first discusses the index system of principles, steps; Secondly establishJilin gas filling station safety risk evaluation index system, to explain the source ofthe index, the index system of structure and the processing method for quantitative;At the same time, comprehensive evaluation and using vapor cloud explosion damageradius model method, risk evaluation, risk degree of grading method, the main factorsaffecting safety filling station is: safety risk assessment of material factors, processequipment, safety management, environmental factors, the operator, formed acomprehensive safety risk assessment results,confirm the grade of major hazards andsafety risk status.Chapter iv Jilin gas filling mother station risk prevention measures, aiming atspecific risk put forward the corresponding countermeasures, including the projectsite selection, general layout, equipment, facilities, management and so on.While the last is the summary of the full text, the gas filling mother station ofJilin city security risk is evaluated, but there are some shortcomings, will need a further research in practice.
