【 摘 要 】
In order to improve the safety of the chemical process, a method combining the fuzzy fault tree analysis (FFTA), the layer of protection analysis (LOPA) and the risk matrix was proposed. Taking the oxidation process as an example, the risk of the ethylene oxide synthesis process was analyzed. Fire and explosion accidents were used as accident consequence scenes to analyze the fault tree. After calculating the fuzzy probability of the top event, the risk level was obtained according to the risk matrix. The result was shown that the risk level was fallen to acceptable level after adding independent protection layers. This method provided a new research direction for risk analysis of chemical process.
