This tab appears on the interface dialog of the the following operation:

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output
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.
•Throwaway %....
If the ‘Consider Throwaway’ option is set in the ‘Oper. Conds Tab’ (see PBA Flow-Through: Oper. Conds Tab), then a percentage of the Flow-Through stream equal to the specified Throwaway % will be sent to the Throwaway stream for each component. This can be useful if you wish to throw away an initial amount of flow-through because it contains little or no amount of valuable product components in it.
