Application of Computational Mass Transfer III Adsorption Process

Application of Computational Mass Transfer (III) Adsorption Process 

Abstract In this chapter, adsorption process is simulated by using computational mass transfer (CMT) models as presented in Chap. 3. As the adsorption process is unsteady and accompanied with heat effect, the time parameter and the energy equation as presented in Chap. 2 are involved in the model equations. The simulated concentration profile of the column at different times enables to show the progress of adsorption along the column as an indication of the process dynamics. The simulated breakthrough curve and regeneration curve for adsorption and desorption by the two CMT models, i.e., the - Sc- model and the Reynolds mass flux model, are well checked with the experimental data. Some issues that may cause discrepancies are discussed.
