Risk Assessment of Sweetening Process for Sour Gas by Using HAZOP Procedure

A hazard analysis is used as the first step in a process used to assess risk. The result of a hazard analysis is the identification of risks. Preliminary risk levels can be provided in the hazard analysis. The validation, more precise prediction and acceptance of risk is determined in the Risk assessment. Hazard and Operability (HAZOP) study is the most widely Hazard analysis tool used for process hazard identification and HSE risk assessment of plans and facilities. The Hazard and Operability (HAZOP) study is a widely used formal technique for examining potential safety and operational problems associated with a system. In this work, hazards of Sour gas sweating Units were assessed by using HAZOP procedure [3,4].
