Update: This function is now automatically calculated in the OLI Studio software as of version 9.3.2
The OLI software calculates fugacities automatically when a gas (vapor) phase is present.
If you are running the OLI Studio you can find the Fugacity Coefficient for a component by turning on the Species Activity/ Fugacity Coefficient section in the Customize option for reports.
For high temperature / high pressure systems where the gas phase is absent, you can still calculate fugacities from the Gibbs Free Energy of Formation and the Standard State Gibbs Free Energy of Formation (other sections in the report).
Here are detailed instructions for how to do this:
