| Summary: | Natural gas is a mixture of methane and some other gases that are actually
impurities. CO2 is considered as a major impurity and an undesirable component that
needs to be removed. Various separation processes are used in the industry for its
removal and adsorption using packed bed is a promising technology for CO2 capture.
Based on regeneration methods, packed bed adsorption utilizes Thermal swing
adsorption (TSA), Vacuum swing adsorption (VSA), Pressure swing adsorption
(PSA) and Electric swing adsorption (ESA). In this work, adsorption process for the
gas mixture is simulated inside packed-bed nanoporous media through Computational
Fluid Dynamics (CFD) approach. Activated carbon is used as an adsorbent to capture
C02. Simulations are performed in a CFD software ANSYS FLUENT® 14. The three
dimensional model used in the simulation for adsorption takes into account the
equilibrium and kinetic properties. |
