To inject huge amount of for CCS application, high pressure pipeline transport is accompanied. Rapid depressurization of pipeline is required in case of transient processes such as accident and maintenance. In this study, numerical analysis on the depressurization of high pressure pipeline was carried out. The prediction capability of the numerical model was evaluated by comparing the benchmark experiments. The numerical models well predicted the liquid-vapor two-phase depressurization. On the other hands, there were some limitations in predicting the temperature behavior during the supercritical, liquid phase and gaseous phase expansions.
