Abstract

This paper analyses the domino effects of LPG storage vessel rupture focusing on the downstream impacts on other plant components. For the purposes of the analysis a stochastic, discrete event simulation model was developed to account both for the heat radiation caused by BLEVE (Boiling Liquid Expanding Vapor Explosion) and for the impact of vessel fragments projected in the surrounding environment. An example analysis is proposed with respect to an actual plant layout, which provides the context for scenario-based testing of the model.
