Comparative Applications of HAZOP, Facility Risk Review, and Fault Trees

3 Comparative Applications of HAZOP, Facility Risk Review, and Fault Trees 

Montague (1990) addresses the problem of selecting the appropriate analysis method for chemical process safety. He describes three methods and provides an example of each. 

Chapter 3 de.scribes the methods (except facility risk review), hence, we go to examples of each. 

A large oil refinery had a failure in their alkylation unit resulting in a significant release of hydrofluoric acid (HF). This incident and others in refineries during recent years prompted members of the hydrocarbon processors to turn to HAZOP to better understand their risks. 

Review the acid unloading system and its procedures to ensure that adequate safety precauiu ms are included for minimizing potentially hazardous incidents during acid unloading operations
