How to generate a Pvap-‐T diagram in HYSYS v8.8
• Open HYSYS • Start Menu>All Programs>AspenTech>Process Modeling V8.8>Aspen HYSYS>Aspen HYSYS V8.8
• Start a New Case: File>New>Case
• Pick component(s)
To get your component list, hit the ADD Button and it will take you to the component selection screen. You can type in the name of the component you want to use (e.g., cumene).
• Choose a suitable fluid Package
• Enter the Simulation Environment and add a material stream
• Set the composition as a single pure component (100% cumene)
• Go to “Flowsheet” tab on the ribbon and select “Property table”.
• Go to Design>Connections and select “Vapor fraction” and Temperature as two independent variables. For a pure component, the value of vapor fraction doesn’t matter. Select the temperature range you need.
• Go to “Dependent property” (right below connections) and select pressure as the dependent variable.
• Click “Calculate”. It should do the calulations. You can see the table and plot on the “Performance” tab.
If you want T-‐xy, P-‐xy or x-‐y diagrams for binary mixtures.
First go back to your component list, add another component, go to simulation environment and change the composition of the material stream.
Go to your unit operations palette, select “Custom” and select “Equilibrium unit operations”.
Double click on the symbol of the Equilibrium unit operations” and add you will have the options to see the plots.
