Risk assessment of Atmospheric Column Overhead Product Drum

The risk analysis plays an important role in the risk management process. Its objective is to identify significant adverse consequences, then assess their severity in order to decide on measures to control the risk. Our study involves conducting a risk analysis related to an un-stabilized naphtha separator ball from the Topping unit located at the Skikda refinery. We applied the HAZOP approach to identify accident scenarios that could be generated by this hazardous equipment. The modeling of the consequences of the chosen phenomenon, which is the BLEVE, was carried out using the PHAST software.
