Hazard and operability study of condensate oil refinery

Abstract

Petroleum refineries are multifaceted and complex systems that perform multiple phase operations characterized by a high level of risk. The size and complexity of petroleum refinery, together with the nature of the products handled, require Hazard and operability (HAZOP) methodology. HAZOP is one of the best tools used in various oil refineries globally based on guidewords for all hazardous conditions with strong recommendation. The application of HAZOP has been demonstrated in the condensate oil exploration unit, based in Sindh. In this research paper about 12 deviations were documented with 34 possible causes and 46 predicted consequences. However, to make the system hazard free 3 nodes were selected on the piping and instrumentation diagram of condensate splitter, based on selected nodes 48 actions were proposed in counter of the deviations.
