Simulation research on fire and explosion risk in oil storage tank area of oil depot

The oil stored in oil depot storage tanks is flammable, explosive and easy to diffuse, once a fire and explosion accident occurs, it will cause heavy losses. In this paper, the fire and explosion accidents in oil storage tank area are simulated and analyzed. The oil steam cloud is formed due to the leakage of underground oil storage tank area and the evaporation of oil vapor. Firstly, for the underground oil storage tank area, TNT equivalent analysis method is used to analyze the influence range of the oil steam cloud explosion when encountering ignition source. Then,for the aboveground storage tank area, the pool fire mathematical model is used to determine the influence degree of fire. Finally, based on the above analysis, the corresponding risk control measures are put forward.
