Estimates for the net rate of bulk liquid and/or separate liquid phases leaving specified trays are entered through this window. The net liquid rates do not include column side liquid products or column liquid pumparounds.
It is generally recommended that net bulk liquid rates be estimated rather than the rates of the individual phases.
Usage
From the Column Main Window , push the Initial Estimate button.
From the Column Initial Estimate Window, push the Net Liquid Rate button.
Enter the Net Liquid Profile data in the table provided. See Editing Tabular Data for further information on entry and editing of tabular data. The dimensional units for net liquid rates may be changed by using the Unit-Of-Measure Selection Window, which is displayed when the UOM button is pushed.
Additional Information
If you wish, you can override all or part of the estimate data provided by the initial estimate generation method. Constant molar liquid flow is used to generate estimates for trays not supplied with estimates. When providing an estimated profile, at least three net liquid flows should be given:
1. Tray one : Corresponds to the reflux.
2. Tray above the reboiler : Reboiler feed which is the bottom product plus the reboiler vapor.
3. Bottom Tray : The "bottom" product.
