Process route index (PRI) to assess level of explosiveness for inherent safety quantification

The fundamental concept of quantification of inherent safety level is based on the ranking of chemical process routes. Three pioneering inherent safety indices (i.e. PIIS, ISI and i-Safe) are based on this concept and have treated the chemicals in the process system as individual components and not...
