摘要：

以某氟化工企业聚合装置中的1 个四氟乙烯计量槽泄漏爆炸为例，对其四氟乙烯泄漏爆炸后果进行定量研究，分析计量槽内四氟乙烯在3 种场景下（不同风速下发生连续泄漏和瞬时泄漏、不同泄漏量）的蒸气云爆炸后果，并计算多米诺事故的影响，得出初次爆炸对周边四氟乙烯聚合釜、氢氟酸储槽、四氟乙烯精馏塔的损坏概率。结果表明，泄漏量是影响蒸气云爆炸危害的关键因素，环境风速次之。由于ALOHA 模拟考虑爆源体积等因素，所以模拟的冲击波超压结果较小，相比于TNT 法更符合实际情况且具工程应用价值。

Abstract: Taking a tetrafluoroethylene metering tank leaking and exploding in a polymerization device of a fluorine chemical enterprise as an example, the consequences of tetrafluoroethylene leakage and explosion in the metering tank were studied quantitatively, and the tetrafluoroethylene vapor cloud explosion consequences under 3 scenarios (continuous leakage，instantaneous leakage under different wind speed, and different leakage amounts) were analyzed. Then, the impact of the domino accidents was calculated and the probability of damage to the surrounding tetrafluoroethylene polymerizer, hydrofluoric acid storage tank, and tetrafluoroethylene rectification tower caused by the initial explosion was obtained. The results showed that leakage is the key factor affecting the hazard of a vapor cloud explosion, followed by environmental wind speed. The simulated shock wave overpressure result is smaller since the ALOHA simulation considers factors such as the volume of the explosion source, which is more in line with the actual situation and has more engineering application value compared with the TNT method.
