This text is intended to provide an overview of methods for estimating the characteristics of vapor cloud explosions, flash flies, and boiling-liquid-expanding-vapor explosions (BLEVEs) for practicing engineers. The volume summarizes and evaluates all the current information, identifies areas where information is lacking, and describes current and planned research in the field. [Pg.1]

Potential explosion phenomena include vapor cloud explosions (VCEs), confined explosions, condensed-phase explosions, exothermic chemical reactions, boiling liquid expanding vapor explosions (BLEVEs), and pressure-volume (PV) ruptures. Potential fire phenomena include flash fires, pool fires, jet fires, and fireballs. Guidelines for evaluating the characteristics of VCEs, BLEVEs, and flash fires are provided in another CCPS publication (Ref. 5). The basic principles from Reference 5 for evaluating characteristics of these phenomena are briefly summarized in this appendix. In addition, the basic principles for evaluating characteristics of the other explosion and fire phenomena listed above are briefly summarized, and references for detailed evaluation of characteristics are provided.

Boiling-liquid expanding-vapor explosion (BLEVE) A BLEVE occurs if a vessel that contains a liquid at a temperature above its atmospheric pressure boiling point ruptures. The subsequent BLEVE is the explosive vaporization of a large fraction of the vessel contents possibly followed by combustion or explosion of the vaporized cloud if it is combustible. This type of explosion occurs when an external fire heats the contents of a tank of volatile material. As the tank contents heat, the vapor pressure of the liquid within the tank increases and the tank s structural integrity is reduced because of the heating. If the tank ruptures, the hot liquid volatilizes explosively. [Pg.228]

The term explosion in a storage and handling sense usually implies the rupture of a vessel. Fauske [191] reviewed the hazards in the chemical industry in connection with storage and processing of chemicals. The major hazards discussed are a boiling liquid expanding vapor explosion (BLEVE) for high-... [Pg.156]

Boiling Liquid Expanding Vapor Explosion (BLEVE) - Is the nearly instantaneous vaporization and corresponding release of energy of a liquid upon its sudden release from a containment under greater than atmospheric pressure and at a temperature above its atmospheric boiling point. [Pg.58]

Liquids that have a normal boiling point well below ambient temperatures are sometimes stored (under their own vapor pressure) at pressures well above atmospheric pressure. If the tank holding the liquid bursts, part of the liquid vaporizes extremely rapidly and expands, forming a shock wave. This process is called a boiling liquid expanding vapor explosion (BLEVE) and the resulting explosion can be very destructive. [Pg.76]

Boiling liquid expanding vapor explosion (BLEVE) or boiling liquid compressed bubble explosion (BLCBE), discussed in Section 2.5.3 and in Guidelines for Evaluating the Characteristics of Vapor Cloud Explosions, Flash Fires, and BLEVEs (CCPS, 1994). [Pg.30]

A Latin American chemical plant experienced a catastrophic fire and series of Boiling Liquid Expanding Vapor Explosions (BLEVEs) that resulted in the loss of one life and 5 million in direct damages (1977 dollars). The initial vapor cloud occurred as a maintenance mechanic started to remove a pneumatic actuator from the liquid discharge line below a tank of flashing flammable liquid that had a boiling point of 7° F (—14° C).
