文摘

The mass transfer modeling of adsorption process inside the fixed-bed column is done through kinetic study of the process. This work includes the parametric analysis of adsorption of CH₄/CO₂ gas mixture inside packed-bed nanoporous media through Computational Fluid Dynamics (CFD) approach. The adsorbent used to capture CO₂ is nanoporous activated carbon. Simulations are performed in ANSYS FLUENT® 14. The three dimensional model used for simulation purposes takes into account the equilibrium and kinetic properties. The adsorption properties are defined through the use of user defined function (UDF). The parametric study involves the investigation of influence of two operating factors namely inlet gas feed flow rate and carbon dioxide feed concentration on the adsorption process and on the carbon dioxide removal efficiency of the process.
