Consequence Modeling of Ammonia Storage Tank in a Chemical Plant-A Case Study
Huge number of accidents every year happens because of adequate attention to the Health and Safety Engineering Management System (HSE.MS). Consequence assessment is one of the most important steps in safety and risk assessment. Consequence modeling refers to the calculation or estimation of numerical values (or graphical representations of these) that describe the credible physical outcomes of loss of containment scenarios involving flammable, explosive and toxic materials with respect to their potential impact on people, assets, or safety functions. This paper presents recommended approaches to consequence modeling for accidental releases of hazardous materials, with the potential to cause harm to people, damage to assets and impairment of safety functions, from offshore and onshore installations. Among consequence modeling soft wares PHAST (DNV software) is explained and a case study is done at one of the Petrochemical Complex in Asalooyein the Persian Gulf on the ammonia storage tanks. Finally some conclusions and recommendations are made.
