Abstract：In order to study the diffusion distance and influencing factors of toxic gas cloud threat caused by epoxy propane(PO)tank leakage in chemical enterprises,based on the Box-Behnken experimental design principle,response surface methodology combined with ALOHA software are used to explore the impact of fac-tors such as leakage aperture,tank filling rate,average temperature,average wind speed,and relative humidity on the area of toxic gas cloud threat caused by epoxy propane tank leakage.Results showed that the maximum threat area of toxic gas cloud caused by PO tank leakage is 2400m.The leakage diameter,filling rate of the tank and its quadratic term,average temperature and its quadratic term have a significant impact on the toxic gas cloud threat area of PO tank leakage.The interactions between average temperature and average wind speed,average wind speed and leakage aperture are significant.The research results can provide reference for the emergency management of epoxy propane storage tanks in chemical enterprises.
