Consequence Analysis of LPG Storage Tank

Abstract

Consequence modeling refers to the calculation or estimation of numerical values (or graphical representation) that describes the credible physical outcomes of loss of containment scenarios involving f1ammable explosive and toxic materials with respect to their impact on people, assets or safety functions. The need to risk assessment and consequence modelling of process plant and hazardous storage facilities has become exceedingly critical due to the trend towards larger and more complex units that process toxic, flammable and otherwise hazardous chemicals under extreme temperature and pressure conditions. Moreover, the proximity of many such units to densely populated areas may magnify the potential damage. There are several types of explosion including deflagration, detonation, dust explosion, vapor cloud explosion and boiling liquid expanding vapour explosion (BLEVE). PHAST RISK analyses complex consequences from accident scenarios, taking account of local population, land usage and weather conditions, to quantify the risk associated with the release of hazardous materials. In this project consequence analysis of LPG sphere is performed by PHAST 6.5.
