Fig. 3.9. Comparison of experimental data and model prediction for the concentration profiles of the lab scale column ([18], reprinted from Chem. Eng. Sci., Vol 57, Beckmann et al., Pages 15251530, Copyright 2002, with permission from Elsevier Science)

In order to model lab-scale experiments the separation performance of the bubble cap trays was derived from our own measurements, while data concerning the reactive packing were provided by Sulzer Chemtech.

Fig. 3.9 shows a comparison between experimental and calculated concentration profiles in the laboratory column. A good agreement between model prediction and experiment can be observed. The simulation was able to describe all experimental data sets with the same accuracy as shown in Fig. 3.9. From these results, it was concluded that the equilibrium stage model is capable of describing the lab-scale experiments based solely on information on phase equilibrium, reaction kinetics and hardware set-up, giving the simulation a predictive character.
