Computational Modeling of Ammonia Dispersion in the Atmosphere in Cases of Accidental Leakage during Road Transport

Year: 2024

Type: article

Abstract: This study aimed to analyze the atmospheric dispersion of dense gases, such as ammonia (NH3), resulting from hypothetical leaks in a truck's cistern during road transport. By employing mathematical models, it was possible to estimate the distance that the gas cloud, formed after an accidental leak, would travel in the atmosphere until it was sufficiently diluted to no longer pose a toxicity risk. The analysis was conducted using the ALOHA software in conjunction with Google Earth to visualize the different scenarios. The results showed that during the nighttime period, scenario 6 exhibited the longest plume reach, with a distance of 484 meters in the red zone. During the daytime period, scenario 4 had the longest reach, with a plume extending 139 meters in the red zone.
