高温热油罐罐顶失效撕裂原因分析及建议

介绍10,000 m³热油罐在某次收付热蜡油时发生罐顶与筒体连接处焊缝异常撕裂事故。通过计算,详细分析了收付油过程中油罐从压力报警、超出压力表量程、呼吸阀打开、呼吸人孔打开、检尺口打开到罐顶焊缝撕裂各阶段压力变化情况,结合油罐承压有限元计算和应力分析,认为油罐性能正常,事故是上游操作波动、油料含水超标所致,并对此提出措施和建议。

The Model of Thermal Response of Liquefied Petroleum Gas Tanks Partially Exposed to Jet Fire

This paper describes a mathematical model developed to study the behavior of liquefied petroleum gas (LPG) tanks when subjected to jet fire. The model consists of a number of field and zone sub-models which are used to simulate the various physical phenomena taking place during the tank engulfment period. The model can be used to predict the pressure and temperature of the LPG in the tank, the temperature of the wall of tank, and the time of tank explosion. The comparisons between the model predicted results and the test data show good agreement. The results show that the jet fire partially impinging on tank wall led to higher wall temperature and the time to failure was shorter than that in engulfing pool fire. And the exposure of the upper wall in the vapor zone to the fire is more dangerous than that of the LPG contacted wall.
