In this study, influence of the operating condition change is focused and reflected to both frequency and consequence assessments. First of all, methodology for applying change of normal conditions (flow rate, pressure, and temperature) is presented. The minimum and maximum conditions are determined according to design basis. It is assumed that distribution of conditions follows beta distribution. This methodology is applied to existing gas treatment unit (GTU) in gas oil separation plant (GOSP). And then, QRA is conducted for each three changes. In this GTU process, distributions of pressure and temperature affect risk, and risk integral increases by 47.7% respectively. This paper contributes to recognize importance of considering dynamic operation behavior in QRA.
