Hazard and Operability study(HAZOP) is a technique in which it is used to identify the possible hazards in a systematic
and step by step manner through which consequences and deviations could be found in several ways during the design stage,
commissioning stage and running stage. In thermic fluid heater the HAZOP study is carried out at the running stage by finding
the possible deviations, causes, consequences through the use of guide word and providing appropriate recommendations to the
actions based on the severity, occurrences and detection. The main process is to eliminate the hazards in a proactive manner in
the thermic fluid heater process by using this qualitative approach and showing results based on the quantitative approach.The
design and operation of thermal fluid-based heat transfer systems (hot oil systems) is often poorly understood and hence
preventable accidents occur due to system failure.
