Abstract:
In this study, hazard risk assessments at the steam generation unit was investigated at an Iranian South Pars gas refinery, using PHA-PRO6 software and considering the HSE management program in its strategic framework, and employing integrated methods and tools commonly employed in such chemical process industries. Recommendations were made to improve safety and prevent possible hazards, taking into account several years of production experiences, past maintenances and reported accidents and near misses. Implicating safety improvements by adopting recommendation yielded from HAZOP studies is expected to reduce system risks and enhance its reliability. The main process hazards identified include water flow fluctuation, pump failures and excess pressure leading to pipe failures. Using the available techniques and standards as well as installing flow control devices could ensure a normal operating pressure is maintained which will in turn reduce pump stoppage and the unit being out of service due shortage of water flow rate. Starting-up procedure for the unit is also revised based on the results of this study.
