Configure the equilibrium options for a Fluid Type that uses the Ideal method

The Equilibrium Options section in the Fluid Editor provides a set of advanced equilibrium options that allow you to adjust your equilibrium calculations to suit your needs. The equilibrium options that are available depend on the type of thermodynamic method that you use as the System method for your Fluid Type.

Due to the ideal nature of the Ideal method, there are a limited number of options that you can use to adjust the equilibrium calculations.

Configure the equilibrium options

1. Open the Fluid Type in the Fluid Editor if the Fluid Type is not already open.

2. Expand the Equilibrium Options section if it is not already visible.

   

3. If the option selected in the Phases list in the System section includes a vapor phase, in the Vapor Equilibrium list, select the thermodynamic method that you want AVEVA Process Simulation to use when it calculates the vapor phase equilibrium properties.

4. Configure the Henry's Law options as you desire.

   See Configure the Henry's Law options for a Fluid Type for more information.

5. (Optional) Select the Include Fugacity Coefficient Variables in Fluid State checkbox to add variables for the fugacity coefficients to the Fluid State model.

   You can now view the calculated values for the fugacity coefficients or use them in other areas of the Simulation.
