Boiling liquid expanding vapour explosion BLEVE

Explosion a confined vapour cloud explosion (CVCE) can result from ignition of vapour within a building or equipment a boiling liquid expanding vapour explosion (BLEVE) can result when unvented containers of flammable chemicals burst with explosive violence as a result of the build-up of internal pressure unconfmed vapour cloud explosion (UVCE) can result from ignition of a very large vapour or gas/air cloud.

An important hazard in the process industry is the boiling liquid expanding vapour explosion (BLEVE). This is understood to be the explosively rapid vaporization and corresponding release of energy of a liquid, flammable or otherwise, upon its sudden release from containment under greater-than-atmospheric pressure at a temperature above its atmospheric boiling point [37]. It is a physical explosion which is a consequence of sudden pressure relief. If a flammable material is involved a chemical explosion or a fireball can follow.

An accident scenario is one of many specific situations that might evolve at the end of an accident sequence. Here, we have considered eight accident scenarios of Vapour Cloud Explosion (VCE), Boiling Liquid Expanding Vapour Explosion (BLEVE) and toxic release events originating from different hazardous industries located in the study area (Fig. 2). The as reference scenarios were selected with an inherent assumption of having the potential of causing Maximum Credible Loss (MCL) (Khan and Abbasi, 2002) as identified on the basis of facility level risk assessment (Table 1).

BLEVE, BOILING LIQUID EXPANDING VAPOUR EXPLOSION Instantaneous release and ignition of flammable vapour upon rupture of a vessel eontaining flammable liquid above its atmospherie boiling point. 

A Boiling Liquid Expanding Vapour Explosion, or BLEVE, is an industrial event related to the laboratory bump occasioned when the inadequately mixed bottom of a vessel of liquid becomes superheated, then explosively boils. In the industrial version, rupture of a pressurised container is usually involved. Although strictly speaking a non-reactive physical hazard, chemical fires and explosions, with fatalities, often follow. Means of estimating risk and prevention, with a fist of incidents are given[l], A more ferocious version, the Boiling Liquid Compressed Bubble...

BLEVE - boiling liquid expanding vapour explosion -an explosion due to the flashing of liquids when a vessel with a high vapour pressure substance fails. 

The methodology, presented in this section, has been developed for the estimation of domino effects due to fragments originating from a BLEVE (Boiling Liquid Expanding Vapour Explosion). Thus the proposed procedure accounts for the Baum s model (Baum, 1995) to compute the initial velocity of fragments. The methodology is composed of two steps ...
