Estimates for the net rate of light liquid leaving specified trays in a liquid-liquid extraction column are entered through this window. Net light liquid rates do not include column side products.
Usage
From the Column Main Window, push the Initial Estimate button.
From the Column Initial Estimates Window, push the Net Light Liquid Rate button.
Enter the Net Light Liquid Profile data in the table provided. See Editing Tabular Data for further explanation on entry and editing of tabular data. The dimensional units for net light 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 flow is used to supply estimates for trays not supplied with estimates. Normally, either net light or heavy liquid flows are provided. When both are provided, care must be exercised that the supplied rates do not conflict.
When providing an estimated profile, at least two net light liquid flows should be given:
1. Tray one : Corresponds to the column "overhead" product.
2. Bottom tray : Corresponds to light liquid feed.
