This work deals with the simulation of the adsorption performance of a packed-bed system. The system uses a 13X molecular sieves as the adsorbent which has a diameter of 2.2 mm. A computer simulation is performed for three different operating conditions, namely, a low, a median and a high humidity conditions. The mathematical model considers both the solid-side mass diffusion effect and gas-side axial dispersion effect. The importance of the gas-side axial dispersion effect to the adsorption performance of the system is discussed. The time-varying temperature and dewpoint temperature of the processed air and time-varying moisture content of the adsorbent in the packed bed, for cyclic steady-state operations, are obtained. A measurement of the system performance is also performed. The experimental data are compared to the simulation results. It is found that, by selecting the Lewis number (Le) as 8.0 in the analysis, a good match between the measured data and simulation results can be achieved.
