风险积分参数RI在LPG站风险分析及评价中的应用

对液化石油气站选址风险进行定量分析,判断风险的可接受性,从而确定选址是否合理。拟建液化石油气站的F／N曲线未知,辨识液化石油气站可能发生的最严重事故,并应用风险积分参数确定液化石油气站的风险。经判断,液化石油气站可能发生的最严重事故为沸腾液体扩展蒸气爆炸（BLEVE）,应用BLEVE火球模型对事故后果进行评价并确定事故影响范围,进而确定影响范围内的最大人数及事故发生频率,在此基础上对LPG站的风险积分参数进行计算。将计算结果与英国安全卫生执行局应用ALARP准则制定的风险可接受标准进行比较。结果表明,该液化石油气站的风险处于合理可接受区。采取一定风险减缓措施后,可考虑在此地点建设液化石油气站。     

The Boiling Liquid Expanding Vapour Explosion (BLEVE): A bibliometric review and futur trends

The phenomenon “Boiling Liquid Expanding Vapor Explosion” (BLEVE) is one of the most common accidental events in the chemical industry and in the transport of dangerous goods. A bibliographic search in the Web of Science Core Collection reported 375 publications related to BLEVEs from 1979 to the present (August 10, 2022). A bibliometric analysis was conducted using the VOSviewer tool to allow a better understanding of the scientific knowledge on this phenomenon. A comprehensive overview of BLEVE research is presented in terms of annual publication, top journals, countries/regions with the highest productivity, authors and their cooperation networks, key terms, and co-citation analysis. The 375 publications cover 691 authors, 83 journals, 44 countries or territories and 290 institutions. The key publication (highest number of citations and co-citations) for understanding the BLEVE phenomenon is. The results obtained constitute a snapshot of the current state of the art on BLEVEs and can be applied to improve the understanding of research on this topic and establish new trends of research.
