A Consequence Analysis of the Explosion of Spherical Tanks Containing Liquefied Petroleum Gas (LPG)

A consequence analysis was performed in one of the gas refineries in Iran to investigate the risks and<br />potential losses resulted from accidents. Specifically, the consequences of an explosion in LPG<br />spherical tanks were modeled using PHAST and MATLAB software. In this paper, three methods of<br />calculation of PHAST software TNT, multi-energy, and BST were used. The results showed that<br />multi energy method is the best method to evaluate overpressure. It was 0.150 bar and 0.159 bar in a<br />distance of 1000 m far from the blast using PHAST and MATLAB respectively. This overpressure<br />can damage a wall with 30 cm thickness. It also affects the human threshold (1%) ruptured eardrum.<br />Finally, it was found that 100% lethality in a minute happened at 285.5 m and 37.5 kW/m2 when the<br />explosion happened.
