This plot indicates that this system contains an azeotrope at an

acetone mole fraction of about 0.34 and a temperature of 64.2° C

(147.5°F). The temperature of the azeotrope agrees with the

literature value within 0.5%, so you could feel confident using the

Aspen Plus default data in a simulation.

6 Select the Binary Analysis Results window which is behind

the Plot window.

The table shows that Aspen Plus has calculated activity

coefficients and K-values as well as temperature and composition.

Use the horizontal and vertical scrollbars to see all the data.

Several additional built-in plots are available using the Plot

Wizard.
