摘要
在详细分析了LNG的危险特性后全面系统地总结了LNG低温储罐的潜在火灾、爆炸主要危险事件;并在此基础上,应用挪威DNV公司的SAFETI定量风险评价软件对某LNG站低温储罐泄漏导致的各主要事故类型(喷射火、闪火、沸腾液体扩展蒸气爆炸和蒸气云爆炸等)进行了详细的后果模拟与定量风险评估,通过构建科学的、针对性强的事故模型,对各类事故后果及其风险水平进行了模拟计算,取得了较真实反映事故危害特性的计算机图表、报告等评价结果,对采取有效措施提高我国LNG的安全管理水平及降低事故风险具有重要的工程应用价值。
The demand for LNG, a kind of clean, economical and high-efficient fuel, is increasing by the high development of economy in China. Based on the application of LNG all over China, this paper analyzed in detail the hazardous features when LNG was being used at different areas, summarizing those main dangerous accidents such as fires and explosions happened to LNG refrigerated storage tank. And then SAFETI software, made by DNV Company in Norway, was adopted to carry out the consequence simulation and quantitative assessment on various accidents, like jet fire, flash fire, BLEVE and VCE, etc., caused by LNG leakage from a certain LNG refrigerated storage tank. This helped build up some individual accidents models in scientific way so as to calculate accurately and objectively on the levels of consequences and risks according to different types of accidents, obtaining assessment results with computer graphs, tables and reports which can reflect hazards and disasters in real way. This study will have great value on taking effective countermeasures to improve LNG safety management and mitigate the risk of various accidents when using LNG in China.
