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

 

○ Active
Check this box to activate this operation.

Yes

Yes/No

○ Manipulated Stream
Indicates the input stream to the process whose flow will be adjusted. Click on the list box to bring up a list of available input streams in order to select one.

<none>

Any Input Stream

○ Set-Point (kg/batch or kg/h)
The desired flow of the procedure’s input (or output) stream.

0.0

Positive

○ Single Component Name
Indicates the component for which a concentration or mass fraction in the input stream to the operation’s procedure will be set. Click on the list box to bring up a list of registered components in order to select one.

<None>

Any Pure Component

○ Include Component ?
Check the box next to a component to include that component to the group of components for which a total concentration or mass fraction in the input stream to the operation’s procedure will be set.

<No>

Yes/No

◙ Concentration (g/L)
The concentration of a single component or a selected group of components in the input stream to the operation’s procedure.

0.0

Positive

◙ Mass Fraction
The mass fraction of a single component or a selected group of components in the input stream to the operation’s procedure.

0.0

Positive

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 Design Spec (Composition): Modeling Calculations.

•Active...

You may wish to keep the design specification operation inactive until your simulation model converges without any errors.

•Composition Specification Options...

You can select a target concentration /mass fraction value for a component or a selected group of components together in a stream.
