You should use ASPEN PLUS to generate your xydiagram for
4D13. Do not forget the step of comparing your diagram with the experimental
data given in your book. Simulate the system of D13 in ASPEN PLUS and compare
the performance of the column you design with McCabeThiele with the column
simulated using the RADFRAC rigorous distillation model.
Assignment Learning Objectives:
·
Perform a design estimate for distillation
columns, strippers, and absorbers using the McCabeThiele method with a range of
flow configurations and process specifications
·
Use ASPEN PLUS to simulate distillation columns
