Configure a Binary Phase Diagram

You can configure a Binary Phase Diagram so that it uses the Fluid Type, composition, temperature range, and pressure range of interest. You can also change the appearance of the Binary Phase Diagram on the graph.

Configure a Binary Phase Diagram

1. On the Canvas, double-click the Binary Phase Diagram to open it.

   The Binary Phase Diagram appears with an expanded configuration area.

2. Expand the General section.

3. In the Title box, enter the title of the graph.

   Note: The title of the graph always includes parenthetical information related to the conditions under which AVEVA Process Simulation calculates the data. This information includes the two components that comprise the binary system and the value of the constant temperature or constant pressure.

4. Specify the fluid that you want to view data for by doing one of the following:

   • In the Fluid Type list, select the Fluid Type.

   • From the Model Library, drag a Fluid Type onto the Binary Phase Diagram.

   After you select the Fluid Type, AVEVA Process Simulation uses property data from the Fluid Type to initialize the Binary Phase Diagram configuration.

   Important: Binary Phase Diagrams currently do not support Fluid Types that use the Electrolyte NRTL (eNRTL) method as the System method.

5. Select either Mole Basis or Mass Basis to view the binary phase data in terms of molar compositions or mass compositions, respectively.

6. Expand the Configure section if it is not already visible.

7. In the First Component list, select the first component in the binary system.

   The Binary Phase Diagram displays all data points based on the composition of this component.

8. In the Second Component list, select the second component in the binary system.

9. In the Compositional Intervals box, enter the number of data points that you want to include in the BVLE calculations. Nonlinear portions of the Binary Phase Diagram may look linear and piecewise on the graph if you do not use a sufficient number of data points.

   This value also determines the number of data points that appear in any Microsoft Excel reports that you generate for the Binary Phase Diagram. See Export Binary Phase Diagram data to an Excel report for more information.

10. In the Calculate at Constant list, select one of the following options:

    • Temperature: AVEVA Process Simulation calculates all data points at the specified temperature.

    • Pressure: AVEVA Process Simulation calculates all data points at the specified pressure.

    The default selection is Pressure.

11. In the Calculate at Constant box, enter the value of the constant temperature or constant pressure.

    The default value for the constant temperature or constant pressure is the initial temperature or initial pressure from the specified Fluid Type, respectively.
