Abstract
In this study, 10% pipe diameter leakage was taken as a typical accident of liquid chemical leakage in bulk at wharf. The leakage rate and evaporation rate of 8 common chemicals were calculated using Bernoulli equation of fluid mechanics and mass evaporation rate. The evaporation rate and the concentration of toxic end point were compared. SLAB model was adopted to analyze the atmospheric environmental risk of chemical leakage under typical accident conditions. According to the calculation results, the atmospheric environmental risk under the scenario of 10% pipe diameter leakage accident was acceptable.
