The study is based on a chemical plant in Kaohsiung Linyuan Industrial Area.
We used ALOHA (Area Location of Hazardous Atmosphere) analysis and simulation software, according to the geographical location and environmental characteristics.
To predict the harmful gas diffusion distribution, after the toluene, methyl ethyl ketone, cyclohexanone, etc.tanks leakage caused by the earthquake. The diffusion results (Figure footprint footprint) nested a Google Earth map, discussed the following items, as a reference to take appropriate control measures and emergency response it to be in advance of disasters can grasp the situation, to reduce disaster risks. .
1. The diffusion hazards analysis of chemical substance in the tank leakage.
2. Effect of changes in wind direction diffusion range of hazards
3. Impact on the degree of diffusion of harmful range difference variation depending on the wind speed.
4. Flammable gas leaks, vapor cloud explosion hazard scope of the analysis.
5.Compare the diffusion hazards difference between methyl ethyl ketone, cyclohexane, toluene, etc.
Forecasting heavy gas cloud chemical diffusion distribution of simulation results are summarized as follows:
1. The simulation results show that the diffusion hazards range order,
is: cyclohexanone> toluene> butanone.
2. The greater the amount of leakage per unit time, the greater the range of diffusion harm.
3. The lower the wind speed, the greater the harm diffusion range.
KeyWords：ALOHA、toluene、 methyl ethyl ketone、 cyclohexanone
