The aim of this project is to develop an interface that able to integrate process simulation (e.g. HYSYS) for estimating the risk owing to the phenomenon of Boiling Liquid Expanding Vapour Explosion (BLEVE). The overall integration network is divided into three stages - (1) HYSYS-ME Interface, (2) mathematical calculation under ME platform and (3) VB-ME Interface. Within HYSYS-ME interface, two models were programmed under steady state simulation. The first model was a storage tank applied for a given problem (Roberts M. W., 2000), while the second model correspond to case study onVessel V-2408 ofMalaysia LNG Dua Sdn. Bhd. For the second stage, three measures ofthe BLEVE consequences - blast, fireball and missile effect, have been considered. The blast effect is estimated based on the established relationship between overpressure and effects, the fireball effect estimated using the thermal intensity and the missile effect is estimated with respect to the distance travel. For the last stage, VB-ME Interface was used to display the BLEVE parameters and effects that were calculated in the previous stage. Overall, this project can be used to evaluation the BLEVE effects on the chemical process operation. Further improvements are necessary to commercialize and integrate this project with other risk effects estimation.
