Development and systematic validation of an adsorption filter model

An analytical model is developed to study the performance of gas-phase filters. This model is validated systematically with experimental results obtained from a small scale and a full scale experimental setup, at various inlet concentrations. The prediction made by the model is then compared with predictions made by two existing models and the experimental data: The developed model performs much better than the others. The validated model is applied to study the effect of the diffusivity within the porous pellets, the air volume flow rate, and the particle size on its performance. The variations of initial efficiency and breakthrough time with respect to changes in these parameters are discussed.
