Runaway reaction of non-tempered chemical systems: Development of a similarity vent-sizing tool at laboratory scale

A new experimental “similarity” vent-sizing tool (A/V ratio) for non-tempered chemical systems was developed. It combines the advantages of both the Design Institute for Emergency Relief Systems (DIERS) method (laboratory scale) and UN method (less overconservative). This tool is based on the VSP2 adiabatic calorimeter. It uses a 0.1 l test cell and allows blowdown experiments to be carried out in the 0.9×10−3 m−1
