This work determines the normal and emergency venting requirements for atmospheric storage tank in a gas plant using ASPEN HYSYS Safety environment. Pressure relief sizing calculations are performed for fire case scenario. Since Aspen HYSYS safety environment is provided with updated industrial design standard codes like API 650, API 620 and API 2000, the results of this study are reliable and accurate. The methodology developed in this work is useful to process design engineers to quickly analyze the low-pressure storage tank protection.
