Consequence modeling of major accidents of a real butane storage tank

Abstract

Chemical accidents are going more frequent with increasing industrialization and increased measured handling of large quantities of chemicals. They can cause major life and property losses and environmental impact if proper safety considerations are neglected. This emphasizes the importance of the consequence analysis of the risks involved with the chemical plants. The purpose of this study is to analyze the consequence of major accidents of a case study in a spherical butane tank in the port of Bandar Imam (Iran). In this work, three possible failure scenarios were studied including (a) leakage from the loading line, (b) leakage from the tank manhole (outlet line), (c) rupture in the spherical butane tank in order to model the incidents. The detailed analysis of the results provided essential and important recommendations that should be taken into account including minimum safe distance from the rupture center for different types of fire. The established recommendations of this work can be used for an effective preparedness of people for relevant risks and could be employed to increase the awareness of possible risks and major accidents.

Experimental data and numerical modeling of flashing jets of pressure liquefied gases

“…Given the toxic or flammable nature of the materials stored as pressure liquefied gases, it is important to predict these hazardous effects within the framework of risk assessment 3,4 . Therefore, the development of numerical models able to simulate the two‐phase flows resulting from breaches or leakages of a vessel containing liquefied gas is of great interest.…”
