“…In earlier experiments by Birk et al [6], Giesbrecht et al [24] and Johnson et al [25], not all of these requirements were met, and are therefore less applicable to the objectives of this paper. For the experiments described in this section, carbon dioxide (CO 2 ) was selected.…”

Explosive evaporation of a superheated liquid is a relevant hazard in the process industry. A vessel rupture during storage, transport or handling may lead to devastating blast effects. In order to assess the risk associated with this hazard or to design protective measures, an accurate prediction model for the blast generated after vessel rupture is needed. For this reason a fundamental understanding of the effects of a boiling liquid expanding vapor explosion (BLEVE) is essential. In this paper, we report on a number of well-defined BLEVE experiments with 40-l liquid CO 2 bottles. The existing inertia-limited BLEVE model has been validated by its application to these experiments. Good qualitative agreement between model and experiment was found, while quantitatively the results provide a safe estimate. Possible model improvements taking into account the finite rate of evaporation are described. These comprise phenomena such as bubble nucleation and growth rate, and the two-phase flow regime. Suggestions for improved experiments are given as well.

“…Due to the 12 long exposure of the tank to fire and to its progressive heating, these two valves were 13 unable to keep the pressure in the container and the third valve opened, originating the 14 whistles heard by the witnesses. Some seconds later, the total loss of containment took 15 place according to a one-step BLEVE mode of failure (Birk, Davison, & Cunningham, 2007). 16 2.…”

10The road accident of a tanker transporting liquefied natural gas (LNG) originated a fire and, finally, 11 the BLEVE of the tank. This accident has been analyzed, both from the point of view of the 12 emergency management and the explosion and fireball effects. The accidental sequence is 13 described: fire, LNG release, further safety valves release, flames impingement on vessel 14 unprotected wall, vessel failure mode, explosion and fireball. According to the effects and 15 consequences observed, the thermal radiation and overpressure are estimated; a mathematical 16 model is applied to calculate the probable mass contained in the vessel at the moment of the 17 explosion. The peak overpressure predicted from two models is compared with the values inferred 18 from the accident observed data. The emergency management is commented. 19 20 Keywords: LNG, Fireball, Road transportation, Blast, Thermal radiation. 21 Highlights 22• Road transportation of LNG is increasing, this implying a certain risk 23• The BLEVE of an LNG road tanker -a rather unusual accident-is analyzed 24• The effects of explosion and fireball are estimated from the observed consequences 25• The correct emergency management avoided further damage to people 26 27 1 1
