This tab appears on the interface dialog of the the following operation:
● Packed Bed Adsorption (PBA) Column Flow-Through
The following table shows a brief description of the variables appearing in this tab. The table also displays their default values and their generally acceptable range:

The following list describes the available specification choices in this tab; for more details on how these are implemented, see PBA Flow-Through: Modeling Calculations.
•If the ‘Set Loading Capacity of <Component>’ option is selected...
You must select a key component and specify the resin’s loading capacity with respect to that component per resin (bed) volume.
•If the ‘Set Total Binding Capacity’ option is set...
You must specify the resin’s total binding capacity per resin (bed) volume. Optionally, you may ignore a component from equipment sizing calculations by checking the ‘Ignore in Sizing?’ box next to that component.
•Loading Time Options...
The loading time can be either set by the user or calculated by the program based on the loading flowrate.
•Loading Flowrate Options...
If the loading time is calculated, you can choose among three different options for specifying the loading flowrate: you can specify the feed’s linear velocity, or its volumetric flowrate, or its relative flowrate (in bed volumes) in the bed. Any variable that is not specified will be calculated by the program.
•‘Consider Throwaway’ option...
If this option is checked, the Throwaway tab will be shown (see PBA Flow-Through: Throwaway Tab) and the Component Throwaway Data specified in this tab will be considered in the calculations. If this option is not checked, then no throwaway will be considered in the calculations.
