Dispersion Study of Pressurised CO2 Release with Obstacles
H.H.P.L. Pham, R. Rusli and M.Z. Abdullah

Abstract:
Carbon Capture and Storage (CCS) is an alternative for decreasing greenhouse gas (GHG) emissions by removing carbon dioxide (CO2) from power plants. Accidental discharges from CCS plant will result in a release of dense CO2 gas cloud to the ambience at high concentration which becomes a dominated threat to human health. However, there is a knowledge gap in assessing the release of CO2 via pipeline leakage. Thus, it is necessary to develop an accurate consequence model for CO2 release in order to demonstrate a safe layout and other safeguards. In this study, pure CO2 discharge and dispersion have been detailed out using a three-dimension model with presence of obstacles in a Computational Fluid Dynamics (CFD) software. The realizable κ-ε turbulence model was chosen for simulating the dispersion of pure CO2-air. A case study based on Kit Fox gas experiments of pure CO2 instantaneous release is developed to evaluate the discharge scenario. The results obtained from the model are compared with experimental data available in literatures and validation is achieved.
