Numerical Simulation of Adsorption and Desorption of Carbon Dioxide by Solid Amine

Objective To establish a numerical model of the adsorption and desorption of carbon dioxide by solid amine bed, and test the simulation results. Method A dynamic model of the adsorption and desorption of carbon dioxide by solid amine bed was setup basing on adsorbent theory of porous medium and the conception of equilibrium adsorptive pressure, and an one-dimension dynamic numerical model for the bed was developed using finite volume method, and the simulation program was tested. Result The characteristics of the adsorption and desorption were abtained by the numerical program. Conclusion The model can correctly describe the adsorption and desorption processes, but the model and parameters should be corrected by further experimental results to improve the veracity.
