基于天然气管线泄漏蒸汽云爆炸危害分析

Hazard Analysis on Vapor Cloud Explosion Based on Nature Gas Pipeline Leakage

基于历史数据和试验建立和改进相应的数学模型,初步建立了定量分析研究天然气管线泄漏蒸汽云爆炸和毒气危害后果计算方法,为天然气管线风险评估、风险管理、管线维护以及蒸汽云爆炸和毒气危害发生后的危害后果评估提供决策支持。

Based on history data and experiments, a relevant mathematic model is established. Meanwhile, a calculation method, providing the decision support for natural gas pipeline risk assessment, risk management, pipe- line maintenance, as well as the hazard consequence assessment after the vapor cloud explosion and toxic gas haz- ards occurred, is built up for quantitatively analyzing and researching the vapor cloud explosion and toxic gas haz- ards.
