Abstract:
The multipuff model is used to simulate a typical sudden accident of environmental risk, with the emphasis on the hydrogen sulfide leak into the atmosphere. Combined with the impact of winds on the role of hydrogen sulfide at a given stability, the maximum landing concentration and the downwind distance of the maximum landing concentration point at a small amount of leakage of hydrogen sulfide are estimated. Analysis concludes that in the same stability conditions, different wind speeds will lead to great difference in the diffusion of hydrogen sulfide, In the simulation process, with the diffusion of a small amount of hydrogen sulfide gas in the atmosphere, though the lethal concentration did not appear, there is a certain risk of hazards. Therefore, the relevant departments should pay enough attention to this kind of air pollution, as well as the surrounding environment and human responses to take the corresponding preventive measures.
