Adsorptive separation by thermal parametric pumping part I: Modeling and simulation

TLDR: A detailed model for the recuperative parametric pumping is presented in this paper, which includes intraparticle mass transfer resistance, axial diffusion and non-linear equilibrium represented by Langmuir equation.

Abstract: A detailed model for the recuperative parametric pumping is presented. The model includes intraparticle mass transfer resistance, axial diffusion and non-linear equilibrium represented by Langmuir equation. The sensitivity studies shows that process performance strongly increases when cycle time increases and φB/φT ratio and particle size decreases. It also shows that bottom and top dead volumes do not influence much the process performance. Evolution of the histories of concentrations and temperatures, the bed performance from cycle to cycle and the bed dynamics at the cyclic steady state have been discussed.
