G. Simulator Problems

G1.

a. If you have access to a simulator such as Aspen Chromatography, repeat Problem 18.D22 on the simulator.

b. Rerun Problem 18.D22 on the simulator, but with km,cap = 100,000 1/min and ED = Eeffective.

c. Compare your two simulator runs.

d. Compare the Lapidus and Amundson solution to the Aspen solutions. Note: you do need to consider convergence and accuracy of the Aspen runs.

G2. Set up a chromatographic column with one feed, a column and a product. The components that adsorb are acetonaphthalene (A) and dinitronaphthalene (DN). Use a model with convection with constant axial dispersion coefficients (0.25 cm2/min for both A and DN), constant pressure, and velocity. Use a linear lumped parameter model with driving force ...
