摘要：Hazardous chemical leakage accidents occur frequently, and once it appears, it will create a great effect. If a more accurate risk assessment impact area can be made in advance, the preventions and controls will play an invaluable role. A propylene storage tank in an industrial park was taken to identify the lying accidents and the risk ranks with the method of Preliminary Risk Analysis. It was found that the propylene poisoning accident and the steam cloud explosion accident have a great threat to the surrounding. With the inputs of relevant parameters, ALOHA software was used to simulate each accident, and the propylene poisoning accident and the vapour cloud explosion accident threat areas were obtained. The simulation provides effective information for the prevention and control of leakage accidents in the propylene storage tank leaking, and provides a scientific guideline for its ordinary safety management.
