A Study on the Prediction of Hazardous Areas of Sulfuric Acid Leakage

Abstract

Sulfuric acid is used for various purposes in industry, but research on sulfuric acid accidents is lacking. Thus, to prepare safety measures, it is necessary to analyze the risk distance for such accidents, particularly sulfuric acid leaks. As part of this study, 112 scenarios of varying wind speeds and leakage amounts were prepared and a risk-distance analysis was carried out at an industrial plant. The scenarios were then analyzed based on hazard concentrations. The analysis revealed that if the entire amount of sulfuric acid leaked from the industrial plant, it spread up to 9,978 m at a wind speed of 6 m/s. Residential areas were also included within the maximum diffusion distance, and it was confirmed that the leak also affected neighboring administrative districts. Therefore, it is necessary to prepare a plan to prevent and respond to sulfuric acid leakage accidents in industrial complexes.
