摘要
对液化天然气罐车在运输过程中发生泄漏后可能产生的事故类型进行分析,利用ALOHA软件对泄漏后引发的喷射火、蒸气云爆炸两种事故后果进行模拟,定量得出事故危害范围,并根据事故后果进行严重程度划分。以广东省某高速公路上发生液化天然气罐车泄漏事故为例,模拟喷射火、蒸气云爆炸的事故后果及影响区域范围,并以实景图的方式直观反映出来,有助于事故发生后的应急救援和紧急疏散。
Analyze the types of accidents after leakage of the liq- uefied natural gas tank in the transport process, simulate the consequences of jet fire and vapor cloud explosion after leakage using ALOHA, consequence range was obtained quantitatively and theseverity classification was made according to accident consequences. Taking a leakage of liquefied natural gas tank ac- cident on a highway in Guangdong Province as an example, the accident consequence and impact area of jet fire and vapor cloud explosion was simulated and visualized as real map, which is helpful for emergency rescue and people evacuation after the ac- cidents.
