A package for thermal parametric pumping adsorptive processes

Thermal parametric pumping is a cyclic adsorptive process based on cyclic c hanges in the bed temperature simultaneously with flow reversal. Simplified models are adequate to describe these cyclic processes with long cycle tim es. Two simplified models are used here: Model I is an equilibrium model pl us axial dispersion and Model II accounts for intraparticle mass transfer w ith LDF approximation. Simulations used parameter values obtained for the s ystem phenol/water/ adsorbent resin Duolite ES861. Model validation is carr ied out by performing experiments in a pilot plant with the system phenylal anine/water/polymeric adsorbent SP206 and using published experimental data for the system phenol/water/adsorbent resin Duolite ES861. A user-friendly package 'Visual Pumping' (VP) is developed in Visual Basic for the simulat ion of thermal parametric pumping processes with educational and training p urposes.
