Define the Top Event: Identify the primary undesired event, such as a decrease in catalytic activity or selectivity. Construct the Fault Tree: Develop a diagram that maps out all possible faults leading to the top event. This includes intermediate events like mechanical failures, catalyst deactivation, and process deviations. Analyze the Fault Tree: Evaluate the fault tree to determine the probability of occurrence for each fault and its impact on the top event. Techniques such as qualitative analysis and quantitative analysis can be used. Identify Countermeasures: Propose solutions to mitigate or eliminate the faults, such as improving catalyst formulation, optimizing reaction conditions, or enhancing monitoring systems.
