Phase diagram problems

2026-03-19View Original

Thread Content

I would like to ask the teachers for help: simulate Example 10.2 from Teacher Sun Lanyi’s course \"Chemical Process Simulation Training\", using cyclohexane as an azeotrope to separate water and ethanol. After the simulation was completed, when checking the compositions at the top and bottom of the azeotropic column, it was found that these compositions did not fall within the same range. Does this violate the principles of the phase diagram, or is it a problem with Aspen’s calculations?
