Quantitative Process Risk Analysis Based on Dynamic Simulation of Gas Gathering Process

Abstract

After nearly fifty years of development, HAZOP (Hazard and Operability study /analysis) has become the most widely used process hazard identifications method, basically covering all areas of petrochemical industry. As technology advancing and people continuing to increase safety requirements, HAZOP quantitative analysis has become a major trend. This paper gives an integration of traditional HAZOP procedure with Dynamic Simulation to quantify the HAZOP deviations and improve the operability of action required. A natural gas gathering process is selected to the application example. Uses the advanced process simulation software ASPEN HYSYS to set the modeling of the gas gathering process, and carry out the dynamic modeling in the light of main problems, and combing the dynamic simulation analysis gets the quantitative analysis results.
