“…The aim at this stage is to evaluate the impact of the effects, according to the vulnerability of the sensitive elements (people and equipment). The evaluation of the impact is estimated based on two parameters: the probability of lethality or thresholds of vulnerability, defined by European project ARAMIS (Planas et al, 2006) precisely French method (Alileche et al, 2015;Gooijer et al, 2012;Kadri et al, 2013;Török et al, 2011) usually used in the Algerian industry. There are not uniform criteria, but thresholds.…”

Purpose Liquefied petroleum gas (LPG), known by its ecological qualities, making Algeria has since the 1980s carried out a policy of development of LPG fuel in substitution of traditional fuels and especially petrol. However, following a series of accidents (fires, explosions, etc). that occurred in 1999, 20 years after the introduction of the LPG in France these incidents led to the search for the strengthening of the safety of the installations by better or new technical and/or organizational measures. This strategy consists in establishing a balance between environmental protection and economic profitability while ensuring the safety aspect. Design/methodology/approach The approach used is quantitative risk analysis authors have identified the potential accident scenarios that consist of leakage and rupture of tanks depend on bow tie. According to the latter using PHAST software, to model these scenarios (thermal, overpressure and dispersion) and their effects on human beings and goods. Findings In this paper, it was noted that there are scenarios such as (jet fire, dispersion), are affected by atmospheric conditions (wind speed humidity), the stronger the wind, the higher the LPG spread unlike instant scenarios (1.3 s for the fireball and millisecond for the explosion) that have not been related to climatic conditions because they have a short duration on the one hand, and on the other hand, a safe distance is given in each phenomenon. Finally, some instructions for drivers and installers have been identified by protective and preventive action. Originality/value Based on a quantitative risk analysis, this work involves modelling potential accident scenarios such as (fireball, jet fire, flash fire and explosion) in the event of a gas leak and rupture in the tank. It aims to sensitize drivers and LPG kit installers, even to get a clear view on these accidental phenomena and how to avoid them.

“…Based on Figure 1, the propane gas started to escape from the 2-inch bottom-venting pipe of sphere tank T61-443 for approximately 10 minutes when the operator failed to close the first valve. It is estimated that the initial mass flow rate of propane released into the atmosphere to be 11.5 kg/s [4]. PHYSICAL PROPERTIES  Appearance: colorless gas.…”

In the case of Liquefied Petroleum Gas (LPG) tank explosion(s), risk impact assessment on the storage facilities must be carried out. Since every LPG tank has its operating condition, it is essential to decide what the best operating conditions are for each tank. This effort is made to avert an accident from happening, as fires and explosions can be devastating in terms of lives lost and destruction to buildings and the environment. Boil-off and/or ignition of flammable gas can cause the pressure in the tank to increase. Therefore, a method called Planas-Cuchi is applied to determine the Peak Side-On Overpressure, P o , of the LPG tank during the occurrence of explosion. Thermodynamic properties of saturated propane, C 3 H 8 , has been chosen as a reference and basis of calculation to determine the parameters involved, such as Explosion Energy, E, Equivalent Mass of TNT, W TNT , and Scaled Overpressure, P S. A cylindrical LPG tank in Feyzin Refinery, France is selected as a point of study in this research. At the end of this study, the most suitable operating pressure of the LPG tank will be determined, and the results are compared and validated using the TNT Equivalent (BREEZE software), Baker-Strehlow model and ARIA investigation report.

“…It is to observe that the fireball lifetime is relatively short (i.e. 10–30 s) compared with the reported minutes required to cause serious plant damage, but the flux intensity is very high (usually in the range of 250–400 kW m −2 at source and in a close proximity), whereas the tank explosion is usually accompanied by launched projectiles/vessel fragments of high speed over a radius of up to 700–800 m In a first accident scenario, the two plants are placed in a moderately close proximity (150‐m distance) and operating under minimum risk conditions, that is a minimum of Bu level in the storage tank ( M = 7.5 t of liquid Bu, ensuring the plant feeding stock for 1 day), and a minimum AN released amount ( G = 50 kg AN vapours in the cloud, corresponding to ca 50 s of relief valve service).…”

Petrochemical complexes include high risk interconnected plants processing large quantities of dangerous/flammable substances, complex reactors of high thermal sensitivity operated under severe conditions of high productivity and associated equipment, vessels or separation units operating at intense temperature and pressures. Such plant design/operation problems contribute quite frequently to the occurrence of small incidents or rare major accidents including domino effects. The study applies classical boiling liquid expanding vapour explosion fire and toxic puff release models to evaluate the effects and consequences of different accident scenarios involving two neighbouring risk plants, with exemplifications for the aniline and maleic anhydride synthesis plants. A proposed joint probability index of human casualties, related to thermal radiation doses and toxic material released around plants, points out the influence of production capacity and plant proximity on the severity of accident consequences and domino‐effect occurrence. © 2013 Curtin University of Technology and John Wiley & Sons, Ltd.
