BACKGROUND
As one of the most frequently occurring accidents in a chemical plant, a fire accident may occur at any place where transfer or handling of combustible materials is routinely performed.
METHODS
In particular, a jet fire incident in a chemical plant operated under high pressure may bring severe damage. To review this event numerically, Computational Fluid Dynamics methodology was used to simulate a jet fire at a pipe of a compressor under high pressure.
RESULTS
For jet fire simulation, the Kemeleon FireEx Code was used, and results of this simulation showed that a structure and installations located within the shelter of a compressor received serious damage.
CONCLUSION
The results confirmed that a jet fire may create a domino effect that could cause an accident aside from the secondary chemical accident.
背景
作为化工厂最常发生的事故之一，火灾事故可能在日常进行可燃材料转移或处理的任何地方发生。
方法
特别是，在高压下运行的化工厂发生的喷射火事故可能会造成严重破坏。为了对这一事件进行数值评估，采用计算流体动力学方法对高压下压缩机管道处的喷射火进行模拟。
结果
对于喷射火模拟，使用了Kemeleon FireEx代码，该模拟结果表明位于压缩机防护区内的结构和装置受到了严重损坏。
结论
结果证实喷射火可能产生多米诺效应，除二次化学事故外还可能引发其他事故。
