A storage site comprises of 3 propane spheres and a fifty-meter diameter butane storage tank on an open site. To reduce the influx of heat from the local soil, the butane storage tank is located one meter above the soil level (asl) on a concrete pylon array. A parking structure with space of 250 cars is located next to the tank farm. An unintentional release of 38.5 tons of Butane (C4H10) due to an accident is postulated in this locality. The C4H10 is released for a 0.1 m diameter leak in the unloading line of sphere. The C4H10 is released mixes with air in a high velocity jet. Input parameters for this situation are given in the table below. INPUT PARAMETERS VALUES heat of combustion C4H10 49700 KJ/Kg molecular weight of C4H10 58.12 (1b/mol) critical pressure of C4H10 549.9 psia mean specific heat liquid C4H10 2500 J/kg/K latent heat C4H10 vaporization 385.71 KJ/Kg boiling point of C4H10 31.0 F boiling temperature of C4H10 at ambient pressure 368.3F process temperature of C4H10 at ambient pressure 431.3F TNT efficiency yield 3% detonation energy of TNT 4.648 MJ/kg i.
