The analysis of approaches to modeling and evaluation processes prior the appearance BLEVE effect during accidents LPG tanks was carried out. is one worst-case scenarios for development an accident, so effective assessment this effect, as well prediction its consequences, integral part safety risk assessment.The results from various sources considered suggest that it vapour energy source shock ...

Several methodologies, based on different thermodynamic assumptions and requiring substance properties and thermodynamic data, have been proposed in the literature for the prediction of the mechanical energy released by a Boiling Liquid Expanding Vapour Explosion (BLEVE) and the associated overpressure. A new method, simple and easy to use, is presented which only requires the vessel filling de...

the main challenge for any insurer/reinsurer has proved to be underwriting major refinery/petrochemical risk. insurers have already considered process risk management measures while accepting and evaluating the risks all over the world. erstwhile petrochemical tariff was adopting experiencing methodology as basis for premium calculation in iran. in the present de-tariff scenario decisions will ...

Many fires and explosions happen in tank farm. A fire and explosion simulation method based on VR is used. Tank fire and explosion special effect is realized by classical particle system. The real-time fire growth model, fireball growth model, fireball heat radiation model are created. The shock wave model of BLEVE also is created. The models and results of FDS (Fire Dynamic Simulator) are buil...
