BVLE Main Window
This window is used to specify the input data for the BVLE calculations. The minimum input data requirements are the required components and the selection of constant Pressure or Temperature calculations.
Component Selection
Select the required first and second components for the equilibrium calculations from the drop-down lists. Both components must be specified.
Pressure or Temperature Specification
Select one of the following parameters and enter its corresponding value:
Pressure : The constant Pressure at which the calculations will be performed.
Temperature : The constant Temperature at which the calculations will be performed.
Number of Evaluation Points
This entry is used to specify the number of data points evaluated for the binary vapor-liquid equilibrium (BVLE) plot. The maximum number of points is 101, the minimum number is 3. The default value is 21.
Plot Options
By default, all of the following plot options are selected:
XY Compositions: vapor composition vs. liquid composition and temperature or pressure vs. liquid and vapor compositions
Liquid Activity Coefficient: activity coefficients or liquid fugacity coefficients vs. liquid composition.
K-values: component K-values vs. liquid composition and component K-values vs. temperature or pressure
Plots are generated by pressing the Calculate button. If Excel is selected on the Plot Setup option on the Options menu, tabular data are available in the spreadsheet. Otherwise, only the plots are shown.
Thermodynamic System
You may select any defined thermodynamic system for the calculations from the drop down list.
