Introduction: In the process industries, especially industries with hydrocarbons uses, due to flammability and reactivity of materials, high temperature, operation pressure, volatility and evaporability of liquid, fire and explosion hazard always has a great significances.The purpose of this study was to assess the quantitative fire safety using DOW’s fire and explosion index, in an oil extract...

In the present paper thecompressibleflowoftheunderwaterexplosionhasbeensimulatedusing One-fluid method along with the Eulerian-Lagrangian ALE method. Besides, the exact Riemann solver and an appropriate equation of state which is consistent with the thermodynamic behavior of water in underwater explosion, is employed. The two dimensional underwater explosion problem near a flat plate is mode...

Background and Objective: Ethylene oxide (EO) is a very toxic and dangerous substance with a high potential for explosion and fire. Ethylene oxide units are among the most hazardous units in petrochemical industries. This study was designed to analyze and model the consequences of ethylene oxide storage tanks explosion in one of Iran's petrochemical industries. Materials and Methods: In this s...

Background and aims: Accidents happened as a result of LPG leakage emphasizes the importance of the consequence analysis of fire and explosion in LPG storage tanks. The purpose of this study is to analysis the consequences of fire and explosion in a cylindrical LPG storage tank in an oil and gas industry. Method: In this analytical study, four possible failure scenarios including 1...

Earthquake and explosion are destructive dynamic forces. These forces can cause severe damage to the structure due to the time-dependent nature of the impact. One of the most important parameters for checking the stability of structures is the study of their buckling modes. The stability check has a direct relationship with the critical load of the columns. In this paper, the effects of simulta...
