Ternary Phase Diagrams

About Ternary Phase Diagrams

Ternary Phase Diagrams generate vapor-liquid-liquid equilibrium (VLLE) data for a three-component system. They help you understand and visualize the binary and ternary azeotropes, liquid-liquid separation, and phase boundaries at the specified conditions.

Concepts

• Unlike Trends and Profiles, Ternary Phase Diagrams appear only on the Canvas, not in the Simulation Manager

• A Ternary Phase Diagram displays data for only one Fluid Type at a time

• The Fluid Type that you use in the Ternary Phase Diagram must contain at least three components and use either the Vapor/Liquid (VLE) or Vapor/Liquid1/Liquid2 (VLLE) selection in the Phases list

• The Ternary Phase Diagram automatically updates when you make any changes to the fluid that it uses or to the configuration of the Ternary Phase Diagram

• If the Fluid Type uses the Vapor/Liquid (VLE) selection in the Phases list, the Ternary Phase Diagram displays only azeotropes, not liquid-liquid equilibrium (LLE) tie lines

• You must specify the first, second, and third component in the ternary system to generate the data; no two components should be the same

• The software generates the azeotrope data at a specified constant pressure

• You can use either an isothermal option or a bubble point temperature option to generate the LLE tie lines

• For the isothermal option, the software generates the LLE tie lines at a specified constant temperature and pressure

• For the bubble point temperature option, the software generates the LLE tie lines at a specified constant pressure and at the bubble point

• Ternary Phase Diagrams display data in the units of measure (UOMs) that are specified in the UOM Slate for the Simulation

Actions

• Create a Ternary Phase Diagram on the Canvas

• Select a Fluid Type for the Ternary Phase Diagram; alternatively, drag a Fluid Type onto the Ternary Phase Diagram

• Select the first, second, and third component for the Ternary Phase Diagram

• Select whether AVEVA Process Simulation calculates the LLE tile lines at a specified isotherm or at the bubble point

• Show or hide the azeotropes on the diagram

• Show or hide the LLE tie lines on the diagram

• Generate a Microsoft Excel report for the azeotrope and LLE tie line data
