Quantitative risk analysis(QRA) of liquefied petroleum gas (LPG) leakage accident

Related Articles

Abstract In order to conduct a quantitative risk analysis (QRA) on the storage warehouse of liquefied petroleum gas (LPG), SLAB model, dynamic BLEVE fireball model and multi-energy model were employed to calculate the dispersion of LPG, the thermal effects and the overpressure. The combination of these models can predict the consequences of such accidents more comprehensively. The calculation results of these models are used to assess the degree of damage to buildings and the probability of human burns. The result shows that the fatality rate due to heat radiation reaches 80% within an area of 8 m in diameter, 50%—75% of the outer walls of the surrounding buildings will be damaged, the highest fatality rate for outdoor people due to overpressure reaches 96%, the evacuation area should be at least 20 m away from the location where the leak occurred. The method used in this research can quantify the risk of liquefied petroleum gas storage, which is helpful for the design of intrinsic safety and the formulation of quantitative specifications.
