Accidental Release of So2 from a Petroleum Refinery due to Power Outage
In normal condition, the petroleum refinery plant in Sriracha, Chonburi, Thailand emits 38.05 g/s of SO2 into the environment. However, if there is a power outage, the same refinery plant emits 16911 g/s of SO2 into the atmosphere .
The ALOHA model was used to simulate the SO2 dispersions in summer, rainy season, and winter .The results show that the SO2 concentrations greater than 0.075 ppm (allowable ambient SO2 concentration) can spread longer than 10 km .
The comparison between the simulated and measured results shows that the error of ALOHA model prediction is 17.63%.
