Perfusion Stoichiometric Fermentation: Perfusion 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

○ Consider Perfusion Mode of Operation Check this box to consider perfusion mode of operation.	No	Yes/No
○ Scalable Check this box to scale operation data in perfusion mode.	No	Yes/No
○ Inlet Stream Indicates the input port that is connected to the inlet stream. Click on the list box to bring up a list of available input ports in order to select one. If an input stream is already present at the selected port, then the button next to the selection is active. Click on the button to bring up the attached stream’s simulation dialog in order to provide its composition.	<None>	Any Input Port
○ Outlet Stream Indicates the output port that is connected to the outlet stream. Click on the list box to bring up a list of available output ports in order to select one.	<None>	Any Output Port
○ Remove Entire Contents at the end of the process	No	Yes/No
◙ Relative Perfusion Rate (Working Volumes/day)	0.0	Positive
◙ Absolute Perfusion Rate (L/h)	0.0	Positive

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

Specification Choices / Comments

Specify whether there is simultaneous feed and removal of material during the reaction, and select the inlet/outlet stream. Then specify either the absolute perfusion rate (volumetric flow rate of material fed and removed) or the relative rate (with respect to the working volume).The required flow of the feed stream is propagated backwards, through the network of connectivity.
