Create a list of components Select an appropriate thermodynamic model BEFORE THE SIMULATION Create a list of components Select an appropriate thermodynamic model

Start a new simulation by clicking on “New Case”

Modify unit sets Select Tools>Preferences In the menu toolbar You can change the number of decimal points in the “Formats” tab You can also define independently units for a specific variable

Insert appropriate streams (mass or energy) Preparing the PFD Insert appropriate streams (mass or energy) Insert appropriate units Insert appropriate conditions Temperature Pressure Flow Degrees of Freedom Heater Valve Pump Mixer Heat Exchanger Separator (flash) Distillation Column Absorber Column

Define the components from HYSYS databanks Define an appropriate thermodynamic model to calculate the fluid properties

You can define hypothetical components from correlations by inserting specific properties, e.g. Tb, MW.

Click “Add” to insert the thermodynamic model

The selection of the model depends on the specific process. If in doubt, you can consult “Methods Assistant”

Material streams

Add streams and units From the “Tools” menu in the toolbar, select “Workbook” From menu “Flowsheet” in the toolbar select “Add stream” or “Add operation” Using the Object Palette Alternatively, you can use F11 (to add stream) and F12 (to insert operation).

Material stream - definitions Blue color indicates values defined by user, Black calculated from the models Define compositions by typing in <empty> Define conditions by typing in <empty> Click on “Composition” tab to define composition Double Click on the selected stream You can select the input and output type of composition by selecting the tab “Basis” When all required input is complete the bar turns green Yellow color indicates undefined variables!

MATERIAL STREAM - PROPERTIES You can select the kind of property you want to add depending on the use of interest, eg. Gas The property is now added A list of available properties appears. You can add a specific property by selecting it and then click on the Apply button You can add more properties by clicking on the + button

MATERIAL STREAM - Utilities Click on the “Utilities” tab Click on the “Create…” button to insert “Envelope” utility Click on the attachments tab
