Figure 7 . Results for the
CHEMCAD, Aspen HYSYS, and DWSIM simulation models. All three agree
within reasonable accuracy.
Figure 8 compares the results for each column with the ideal stage
model. For the TPR column, both the argon and nitrogen values match the
model at around 4.5 stages. For the PTL column the argon and nitrogen
values match the model at around 5 and 7 stages, respectively, while for
the AMPH column both argon and nitrogen match at around 8 stages.
