Numerical Simulation of Leakage in Vinyl Chloride Storage Tank Area Based on COMSOL
In response to the vinyl chloride leakage accident,taking the vinyl chloride storage tank area of a typical chemical enterprise in Xinjiang as an example,COMSOL was used to simulate the effects of wind speed,direction,and leakage aperture size on vinyl chloride storage tank leakage.According to the hazardous gas exposure criteria for vinyl chloride,the toxicity of vinyl chloride is classified into four levels.The concentration thresholds of mild and immediate lethal areas were used to determine the medium risk concentration of 0.000 56 mol/m3 and the high-risk concentration of 0.103 mol/m3 for vinyl chloride.This paper provides effective guidance for the prevention and rescue of vinyl chloride leakage accidents in chemical plants.
