摘要：The accurate prediction of environment risk of liquefied ammonia leakage accident is meaningful for reducing the injury to the maximum extent. In this paper, the overall process in terms of the hypothesized liquefied ammonia leakage accident is firstly analyzed. Then, the prediction of influence range of toxic gas cloud and the changing principle of source density based on physical and chemical dispersion model is given in order to decide whether the residents and animals should escape or stay indoors when facing the accident. Furthermore, the accident consequence of liquefied ammonia leakage on environment is simulated and analyzed based on ALOHA. And the acting factors including wind speed, stability of environment, ground roughness and the corresponding effecting mode are given, which provide useful suggestions for rescue planning. ?
