摘要： 为探究综合加能站内部区域发生泄漏的事故风险，利用FLACS软件构建综合加能站的多区域泄漏扩散分析模型。首先，对综合加能站内可能发生泄漏的区域和场景进行辨识；其次，结合事故案例和综合加能站的结构布局，确定可能发生泄漏场景的具体工况参数；最后，针对不同泄漏场景开展后果分析。结果表明：制氢区、加氢区的危险气云体积和扩散距离主要受泄漏压力的影响，制氢区域的泄漏危险气云容易扩散至LNG区域，一旦遇点火源发生爆炸，易引发多米诺效应，威胁LNG区域的安全；LNG泄漏孔径达到50 mm时，泄漏的LNG容易在地面形成液池，可燃气云受风场的影响会迁移至制氢区域，发生爆炸会影响制氢区域的设备运行安全。针对不同区域的泄漏风险，提出减缓各区域泄漏事故后果的建议措施。

Abstract: To explore the accident risk of leakage in multiple areas for a comprehensive energy station, an analysis model of multiple leakage scenarios for a comprehensive energy station was constructed using FLACS software. First, the leakage scenarios where leakage might occur in the comprehensive energy station were identified, and the specific condition parameters of the possible leakage scenarios were determined in combination with accident cases and the layout of the comprehensive energy station. Then, the leakage consequence analysis was carried out for different leakage scenarios. The results showed that the volume and diffusion distance of the gas leakage in the hydrogen production area and the hydrogenation area were mainly affected by the leakage pressure. The leaked dangerous gas cloud in the hydrogen production area was prone to spreading to the LNG area. Once an ignition source explodes, it was easy to cause a domino effect, threatening the safety of the LNG area. When the LNG leakage aperture reached 50 mm, the leaked LNG was easy to form a liquid pool on the ground, and the combustible gas cloud would migrate to the hydrogen production area under the influence of the wind field. Once an explosion occurred, it would affect the safety of the equipment operation in the hydrogen production area. Some suggestions were provided to mitigate the consequences of leakage accidents in multiple areas for different leakage scenarios.
