Abstract

In order to study the hazard of LPG storage, quantitative risk assessment is proposed to analyze the accident scenarios. The consequence models specific to the leak of LPG storage is put forward and the software Phast Risk is used to calculate the individual risk. The results of typical historical accidents show that BLEVE, vapor cloud explosion and flash fire are the major accident scenarios according to the different leakage apertures. Fireball model, TNT equivalent method, heavy gas dispersion model can be used to calculate the consequences of LPG leak. The case study shows that required minimum distances between hazards and vulnerable objects should be 600 m, 800 m, 900 m, corresponding to the low-density, high-density, and special high-density places, respectively. This study provides data support to determine the safety distance of the chemical plant and the surrounding environment from a risk management point of view.
