摘    要:针对液氨储罐孔洞泄漏的实际工况,综合考虑泄漏及由于泄漏导致液氨闪蒸造成 的罐压变化,以及储罐的许用压力,对其连续泄漏过程进行了分析,以此改进现有的泄漏扩 散后果分析模型,获得较忽略这些因素更为严重的后果.最后针对灾难性事故发生前连续泄 漏最大持续时间的影响因素进行了分析.结果表明,环境温度与初始罐压对其影响较大,是决定...

关 键 词:液氨储罐  模型改进  后果分析  敏感度分析  风险评价

Abstract:Based on the actual condition of liquid ammonia vessel hole release,the variability of pressure of the vessel resulting from liquid ammonia release and flash and the relief pressure of the vessel,this paper analyzes the process of continuous release and so the accident consequence models are improved,by which more serious catastrophic consequence is obtained.Finally the parameters of maximum duration before catastrophic failure are analyzed.The ambient temperature and initial pressure of vessel is key to de...
Keywords:liquid ammonia storage vessel models improvement consequence analysis sensitivity analysis risk assessment
