【摘要】 对海底输气管道系统天然气泄漏的环境风险进行了初步的定量分析,计算了不同破损情况下天然气的泄漏速率、发生泄漏后天然气在海面的浓度分布、天然气燃烧热辐射危害阈值12.5kW/m2对应的危害半径和天然气爆炸冲击波危害阈值0.010MPa对应的危害半径,可为制定天然气泄漏应急预案提供参考。更多还原

【Abstract】 This paper analyses the environmental risk of natural gas leakage in subsea gas pipeline system quantitatively. The leakage speed under different pipeline damage conditions, the concentration distribution of leaked natural gas above the sea surface, the heat radiation harm radius with the threshold of 12.5 kW/m2 when the natural gas is burning and the shock wave harm radius with the threshold of 0.010 MPa when the natural gas is exploding are computed. All these data can be referred by the natural gas leakage emergency programming.更多还原
