The use of two different thermodynamic/activity models (NRTL and UNIQUAC) led to some differences
in the simulation results. In the following discussion, results from both NRTL and UNIQUAC are provided
when there exists a big difference between them. Otherwise, the results shown are based only on the NRTL
model. Unless specified, all percentages are expressed as mass percentages and the sizes of all process equipment
are described as diameter height
