Batch Component Splitting: Oper. Conds Tab

Variable Definitions, Ranges and Default Values

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:

Variable	Default Value	Range

○ Outlet Port Indicates the output port that is connected to the split stream. Click on the list box to bring up a list of available output ports in order to select one.	<none>	Any Output Port
○ Is Scaleable ? Check this box to scale up or down the operation data (in this case the specified split or retained component amounts). Note that this box is only enabled if the amount is set for at least one component.	Yes	Yes/No
○ Consider Solids ? Check this box to specify component splitting or retention data for solid components only.	No	Yes/No
● Is Solid? This box is only displayed if the “Consider Solids” option is checked. Also, it cannot be set by the user. The program will check or uncheck this box automatically depending on whether the user has checked or unchecked, respectively, the ‘Is Solid?’ property of the corresponding pure component through the Pure Component Properties dialog.	No	Yes/No
○ Is Particulate Solid? This box is only displayed if the “Consider Solids” option is checked. Also, it cannot be set by the user if the ‘Is Solid’ box is unchecked. If the ‘Is Solid’ box is checked, you can check this box to indicate that the corresponding solid component is a particulate solid (as opposed to a dissolved solid).	No	Yes/No
○ Split % (or Retained %) ‘Set Component Splits To Output Stream’ option: The split percentage of each component from the selected source (total contents, liquid phase or vapor phase) to the selected outlet port ‘Set Retained Components In Final Contents’option: The retained percentage in the final contents of each component contained in the selected source (total contents, liquid phase or vapor phase).	0.0	0-100
○ Amount (kg) ‘Set Component Splits To Output Stream’ option: The amount per batch of each component that is split to the selected outlet port. If the amount is specified, and the specified amount exceeds the available amount in the vessel, then a split percentage equal to 100% is assumed. ‘Set Retained Components In Final Contents’option: The amount per batch of each component that is retained in the final contents. If the amount is specified, and the specified amount exceeds the available amount in the vessel, then a retained percentage equal to 100% is assumed.	0.0	Positive
◙ Total Solids in Output Stream (or Total Solids in Final Contents) (%) The mass fraction of particulate and dissolved solids in the output stream (or final contents), converted into percentage.	15.0	(0,100)
◙ Particulate Solids in Output Stream (or Particulate Solids in Final Contents) (%) The mass fraction of particulate solids in the output stream (or final contents), converted into percentage.	15.0	(0,100)
○ Setup Time (min) The amount of time (per cycle) spent before each operation is carried in preparation for the actual execution of the operation. It may involve actions like cleaning, vacuuming, setting up of equipment, etc. which the user opted not to model explicitly.	15.0	Positive
◙ Process Time (min) The actual duration of the operation.	0.0	Positive
◙ Mass Flowrate (kg/h) The inlet mass flow rate.	600.0	Positive
◙ Vol. Flowrate (L/h) The inlet volume flow rate.	600.0	Positive
○ Ignore Labor? Check this box to ignore labor for this operation. This option is used only if the process time is set by a master-slave relationship.	Yes	Yes/No

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output

Specification Choices / Comments

The following list describes the available specification choices in this tab; for more details on how these are implemented, see Batch Component Splitting: Modeling Calculations.

•Outlet Port...

Select one of the available output streams for this operation as split stream. Note that multiple split operations can use the same split stream. In such a case, if you visit the dialog of that stream, you will see the sum of all materials transferred using that stream.

•Material Balance Options

Two options are available for specifying the component mass balances: you can either set the component splits from the selected component source to the output stream or the retained components of the selected source in the final contents. As component source, you may choose among three different options (total contents, liquid phase or vapor phase).

If you select the option to set the component splits to the output stream, then for each component you must specify either the split percentage or split amount from the selected component source to the output stream. If you select the option to set the retained components in the final contents, then for each component you must specify either the retained percentage or retained amount of the selected component source in the final contents. Based on the specified component data, the program will do the component mass balances to determine the component amounts that must be split to the output stream and the component amounts that must be retained in the final contents.

If you select total contents or liquid phase as component source, then you can also check the option to consider solids. If that option is checked, then the components table is used to specify component splitting/retention data only for particulate solid components (i.e., undissolved solids, suspended or precipitated). Only pure components that are set as solid through the Pure Component Properties dialog can be set as particulate solids in the components table. In addition to setting one or more solid components as particulate solids and specifying the splitting (or retention) data for those components, you must also specify either the total (particulate and dissolved) or particulate solids percentage of the output stream (or final contents). Based on this information, the program will calculate the component splitting/retention data for all other components besides particulate solids (i.e., dissolved solids, liquids and gases).

•Duration options...

You can set the process time (component splitting time), or have the process time calculated based on either on the volumetric or mass flowrate during transfer, or match the duration of this operation to the duration of another operation by introducing a master-slave relationship between the two operations. If you introduce a master-slave relationship, the program will match the setup time, the process time and the turnaround time of this operation (the ‘slave’) with the corresponding times of the reference operation (the ‘master’ operation). For more details on how to setup a master-slave relationship, see The Scheduling Tab.
