Define - Column Parameter Selection
This window is used to select a column parameter for the Define system. The column internal stream properties are included in these parameters.
Usage
From the Define - Parameter Window, select the desired column for the reference parameter. Click on the "Parameter..." text to display the Column Parameter Selection Window.
The Column Parameters Available for Referencing are grouped into different categories as displayed in the Parameter list box. Select the category to which the desired reference parameter belongs.
The selected category may be further sub-divided into more categories. You will have to make a maximum of three such selections in this window to specify the desired column parameter.
If you have selected any of the tray properties, you must enter the appropriate Tray Number. Similarly, if you have selected either the "Selected Component Flowrates" or "Compositions" sub-categories of the tray vapor and liquid properties, you need to specify the Starting Component. The Ending Component defaults to the starting component and can be changed if desired.
For properties like volume, composition and flowrates you need to specify the Wet/Dry Basis and the "Distillation Curve" properties require a selection for Volume Percent Distillate.
Note that the data entry windows guide you through the required entries by making them available as you make the appropriate selections in the list boxes. When you return to the Define - Parameter Window, the parameter will be displayed in place of the original "Parameter..." text.
