Configure the Fluid Type in AVEVA Process Simulation for the Bosen-Engels approach

To successfully use the Bosen-Engels approach for electrolyte fluids, you must configure the Fluid Type in AVEVA Process Simulation so that it uses the correct thermodynamic method, calculations, and custom data banks.

Configure the Fluid Type for the Bosen-Engels approach

1. Open the Fluid Type in the Fluid Editor.

2. In the System section, in the System list, select Non-Random Two-Liquid (NRTL).

3. In the Binary Interaction Banks area, select Expand,and then add the user data bank that contains the binary interaction data for your electrolyte species to the list of data banks that the Fluid Type uses. We recommend that you add your user data bank to the top of the list.

4. In the Pure Component Property Override Data Bank box, enter the name of the user data bank that contains the component property data for your electrolyte species.

5. In the Equilibrium Options section, select the Include Activity Coefficient Variables in Fluid State checkbox if it's not already selected.

6. In the Property Options section, in the Enthalpy/Entropy Route list, select Custom.

7. Select the Include Heat of Mixing (Excess Enthalpy) in Liquid Enthalpy Calculations checkbox

8. In the Component List section, do the following for each component in the Fluid Type:

   1. In the Enthalpy Basis list, select Sat. Liquid.

   2. In the Ref T column, verify that the reference temperature is 298.15 K (25°C).

   3. In the Ref H column, enter the enthalpy of the liquid at 298.15 K (25°C). You may need to calculate the value by subtracting the latent heat of vaporization from the ideal gas heat of formation at 298.15 K (25°C).

9. In the Models section, in the Reaction box, enter the name of the reaction submodel that you want to use for the Fluid Type.
