本科论文摘 要近些年我们国家的 LNG 能源应用越来越广泛，LNG 也在高速发展中。也普遍存在着 CNG、LNG 综合加气站的修建，国家也有相关的鼓励政策。在使用过程中，加气站也始终有着很大潜在的危险性，如火灾、爆炸等重大危险。虽然随着科技的发展，严格控制下的危险发生可能性很小，若真的由于某些原因发生事故，事故是灾难性的。针对可能发生的事故我们应当重视加气站的安全危险辨识及安全评价研究。本论文对 LNG 加气站进行基本情况进行了解，对加气站内设备设施及重要工艺流程进行了解，在此基础上对加气站进行安全危险辨识。通过学习选择适合本文安全评价方法进行安全评价研究。根据加气站内危险源辨识进行定性、定量安全平价研究，并通过运用 TNT 当量的定量研究计算出部分 LNG 泄漏后爆炸的死亡半径、轻伤半径、重伤半径及财产损失半径。并提出相应的安全措施。关键词：LNG；LNG 加气站；危险源；辨识；安全评价本科论文AbstractIn recent years, LNG energy has been used more and more widely in our country, and LNG is also developing at a high speed. The construction of CNG and LNG comprehensive filling stations is also widespread, and the state has relevant encouraging policies. In the use process, the gas filling station also always has great potential risks, such as fire, explosion and other major risks. Although with the development of science and technology, the possibility of occurrence of danger under strict control is very small, if an accident really occurs for some reason, the accident is disastrous. For possible accidents, we should pay attention to the safety hazard 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, the safety hazard identification of the filling station is carried out. Through studying and selecting the safety evaluation method suitabl...
