Abstract

To scientifically evaluate the danger of acetochlor production process, this article identifies and analyzes dangerous and harmful factors in a company’s factory from dangerous and hazardous substances, equipment, and places, etc, fire, leakage and explosion are the main risk factors of the plant. Taking the ethanol storage tank leakage in the storage area as an example, the FLUENT software was used to simulate the leakage of ethanol, and it was found that the leakage outlet emitted a concentration of more than 8% and migrated to the windward side, which was extremely prone to vapor cloud explosion. Then, the TNT equivalent explosion model was used to calculate that the vapor cloud explosion may cause the death radius, severe injury radius, and minor injury radius to reach 57.27m, 138.39m, and 252.21m. At the same time, the radius of explosion damage under other overpressures was calculated. Based on this, suggestions for targeted safety countermeasures can be provided, which can provide a reference for accident prevention and emergency treatment.
