摘要
液化石油气(LPG)在其运输和存储过程中存在着各种与火灾和爆炸相关的危险性。由于LPG的泄漏可能导致包括闪火,不可控蒸气云爆炸,沸腾液体膨胀蒸汽爆炸等一系列灾害的发生,针对上述的各种灾害的具体发生条件及其危险性进行了分析;在事故后果评价中采用量化风险分析,提出了沸腾液体膨胀蒸汽爆炸和不可控蒸气云爆炸对周围人员可能造成伤害的评价方法。
The liquefied petroleum gas (LPG) has multifarious risks associated with fire or explosion in the traffic and storage process. The leak of LPG can induce disasters including flash fire, unconfined vapor cloud explosion (UVCE), boiling liquid expanding vapor explosion (BLEVE), etc. In this paper, occuring condition and risk of those disasters are analyzed. Quantified risk analysis (QRA) is used in consequence assessment. The assessment method for the hazards to the environment by UVCE and BLEVE is researched.
