The Effect of Reducing the Volume and Working Pressure Propane Tank on the Consequences of the Effects of Flash Fire and Jet Fire

Propane is classified in gas hydrocarbons and storage as a liquid in tanks is used as fuel for machines and heating equipment. Given that, the main risk associated with propane is the risk of high flammability. The aim of this study was to investigate the effect of reducing the volume and working pressure propane tank on the consequences of the effects of flash fire and jet fire.
This cross-sectional study was done on a tank containing propane single-phase material in Kerman Sarcheshmeh copper complex in 1395. Information about this study was collected through a field survey. Risks related to the tank were identified and possible scenarios were selected based on identifying risks. The data obtained were analyzed by PHAST software.
Most sudden fire death rate was related to leakage from a 150 mm gap in the first scenario with a radius of 254 meters and the lowest affected death was due to thirtieth scenario with a radius of 109 meters. Most radiation (37.5 kW/m2) of fire that caused deaths and destroyed the surround building was the third and fourth scenario with a radius of 105 meters. The least death consequence with a radius of 39 meters was due to thirteenth scenario.
The modeling results in different types of fire modes, showed that effect of consequences could be reduced significantly with half the volume and pressure.
