摘要/Abstract

摘要： 10 000 m³的立式内浮顶储罐在成品油站场中数量最多，为研究汽油泄漏扩散行为，考虑相邻罐之间的影响，通过FLACS软件，按照标准建立罐区三维模型，基于pool模块，分别讨论液池和可燃气云在不同泄漏速率、温度、风速影响下的扩散行为。研究结果表明，双罐区的液池和气云扩散主要受相邻储罐的阻挡而绕流扩散，随后与单罐区一样，受到防火堤的约束；根据在30 s形成的液池面积大小及可燃气体扩散最远距离来评价汽油泄漏后的灾害严重程度，发现泄漏速率越大、风速较小且稳定时，液池及可燃气云扩散速度越快，危险程度越高，而温度对液池扩展及气云扩散影响较小；结合监测点的实时气体浓度信息及GB 50493——2019相关规定，建议罐区可燃气体探测器设置在泄漏源附近，高度设置为0.3 m。

Abstract: The largest number of vertical internal floating roof tanks in the refined oil station is 10 000 m³, In order to study the diffusion behavior of gasoline leakage and consider the influence between adjacent tanks, a 3D model of tanks is established according to the standard by FLACS software. Based on the pool model in FLACS, the diffusion behavior of pool and combustible gas cloud under the influence of different leakage rate, temperature and wind speed are discussed, respectively. The results show that the diffusion of pool and gas cloud in the double tanks is mainly restricted by the adjacent tank. Then, as in the single tank farm, it is restrained by fire dike. The severity of the disaster after gasoline leakage is evaluated according to the size of the pool and the furthest distance of combustible gas diffusion in 30 s. It is found that the greater the leakage rate, the smaller and stable the wind speed, the faster the diffusion speed of pool and combustible gas cloud, the higher the risk degree, while the temperature has little impact on the expansion of pool and gas cloud diffusion. Combined with the real-time gas concentration information of the monitoring point and the relevant provisions of GB 50493--2019, it is suggested that the combustible gas detector in the tank farm should be set near the leakage source with a height of 0.3 m.
