Study on Flow Dynamics of Carbon Dioxide/Natural Gas in a Nanoporous Adsorbent-based Adsorption Column

This study will investigate the flow dynamics of the carbon dioxide-natural gas flow in a nanoporous adsorbent-based adsorption column through computational approach. The process is simulated through the use of computational fluid dynamics (CFD) software by varying the process parameters such as particle diameter sizes, column geometry and column dimension. The proposed dimensional characteristic of the column to be studied is in a demo sized version, which is predicted to be about 50 times larger than the current studied lab-scale version. In this study, the actual adsorption rate of CO2 by the nanoporous adsorbent is not considered, whereby the simulation is merely based upon the ‘non-reactive’ flow of the gases through a porous domain. It is expected that the analysis of the flow dynamics for the process would provide a viable information on the possible operating conditions for the demo scale adsorption column that would be used in the design of the actual version for the purification of CO2 from natural gas.
