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

 

Stream Name
Indicates the input port that is connected to the respective input stream.

<None>

Dedicated Input Port

Split %
The percentage of the component that is directed to a specific stream.

0.0

0 - 100

Total (%)
The sum of split percentages of a component to all output streams.

0.0

0 or 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.

0.0

Positive

Process Time (min)
The actual duration of the operation (per cycle).

60.0

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

Operating Throughput per Unit (kg/h)
The mass flow rate of the feed stream divided by the number of equipment units.

0.0

Positive

Pressure Set by User
Check this box to set the pressure.

No

Yes/No

Pressure (atm)
The operating pressure of the vessel.

1.0

Positive

Consider Ambient Effect
Check this box to include the ambient effect to the energy balance.

No

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 Component Splitting Operations: General Description.

Splitting Options...

For each component present in the feed stream specify its fraction in each output stream.

Duration...

The duration controls appear only if the procedure in batch mode. In Rating Mode, you have a choice to either set the process time (and the setup time) or to allow the process time to be specified (based on the throughput). In Design mode, you must specify the process time (and the setup time) in order for the program to calculate the rated throughput.
