Abstract
Process hazard analysis is significant in improving process safety in complex systems. Hazard and operability study (HAZOP) is one of the event-based methods of displaying hazards in the process industry, which can identify a wide range of hazards throughout the process life. However, HAZOP would repeat work on the same failure and lack a global view, as well as the result is not highly readable and reusable. Therefore, a hazard analysis procedure based on Multilevel Flow Modeling (MFM) is proposed. The procedure divides the system into sub-objectives and flow-based structures, subsequently analyzing and modeling hazard knowledge in terms of the objects and agents that realize the function. By comparing with a HAZOP report of the Minox process in a water injection system, it is demonstrated that MFM-based hazard analysis shows the potential for a more systematic and comprehensive representation of process hazards to improve process safety management.
