The vapour pressure data for H2O is included in SysCAD. Users can add new species to the list by following these steps:
We will use ammonia as an example:
- Edit the SysCAD Database to include both the liquid and vapour phase of ammonia.
- For NH3(g), make sure the field Vp and Tc contain valid data. (See Species Table - Vapour Pressure for further information.)
- Next, close any opened projects and edit the project configuration file to include NH3(g) and NH3(aq) in the Display List. (See Species Configuration for further information.)
- Caution SysCAD VLE currently only supports a single liquid phase species. Only one of NH3(aq) and NH3(l) can be used within VLE calculations (the other is ignored).
- Reload the project and the ammonia should be available as a flash component.
- Choose ammonia from the VLE Tab Component droplist.
