Heavy liquid composition data may be used to improve the initial estimate for highly non-ideal liquid-liquid extraction columns.
Usage
From the Column Main Window, push the Initial Estimate button.
From the Column Initial Estimates Window, push the Heavy Liquid Composition button.
Enter the estimated component heavy liquid mole fractions for desired trays in the table provided. Tray numbers are entered in the top row of the table. Components are selected using the drop-down lists and heavy liquid mole fractions are entered in horizontal rows, under the tray numbers. See Editing Tabular Data for further explanation of tabular data entry and editing.
Additional Information
If you wish you can override all or part of the estimate data provided by the initial estimate generation method. Heavy liquid mole fraction data are determined by linear interpolation for trays that are bracketed by estimates.
It is good practice to supply compositions at several trays over the range of the column for highly non-ideal applications. Minimum suggested locations are the top and bottom trays.
