The present paper has introduced three equipments, i.e. Accelerating Rate Calorimeter (ARC), Vent Sizing Package (VSP) and Reactive System Screening Tool (RSST), useful for the study and simulation of runaway reaction. The above equipments can be made use of calculating the relief diameter and the discharged mass flow so as to obtain the expected pressure and temperature data of runaway reaction. In accordance with the DIERS classification, three reacting systems are classified for the venting size purpose, i.e. the vapor system, the gaseous system and hybrid system. With each respective system the methods of emergency relief design are different. The present paper has illustrated and compared most commonly adopted design methods, such as DIIERS method, API520 method, DIERS engineering method and Omega method. What seems important is that it is necessary to select models and scenarios in designing the above said pressure relief system. For example, the DIERS engineering method can be used for simple calculation for simple results of venting size. While the DIERS method can be used to calculate W and Omega to calculate G, venting size A can be deduced by the formula of A=W/G, though further research of the emergency relief venting size is still needed.
