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

 

Sorption (%)
The sorption percentage of a component.

0.0

0-100

Water Comp.
The primary biomass water component.

 

 

Content (% wt)
The intracellular water percentage (by weight). The simulation engine will automatically assign the appropriate amount of ‘Water’ as intracellular

 

 

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

This interface is used by a number of bioreaction operations including:

      Continuous Stoichiometric Photobioreaction

      Stoichiometric Well-Mixed (WM) Aerobic Bio-Oxidation

      Kinetic Well-Mixed (WM) Aerobic Bio-Oxidation

      Stoichiometric Plug-Flow (PF) Aerobic Bio-Oxidation

      Kinetic Plug-Flow (PF) Aerobic Bio-Oxidation

      Stoichiometric Anaerobic Digestion

      Kinetic Anaerobic Digestion

      Stoichiometric Anoxic Reaction

      Kinetic Anoxic Reaction.

SuperPro Designer keeps track of the percentage of a component that is adsorbed on the Primary Biomass component using the ‘Extra-Cell %’ term that is displayed on stream dialogs. More specifically, the ‘Extra-Cell %’ term represents the percentage of a component that is in solution while 100 - Extra-Cell% represents the adsorbed portion of a component (the intra-cellular percentage).

Please note that the ‘Sorption %’ specification cannot be set for the primary biomass component and also, for pure components whose ‘Extra-Cell %’ can be specified otherwise. For example, in the Continuous Stoichiometric Photobioreaction operation, if a pure component is specified as product in a reaction that also produces the primary biomass component, then it is possible to specify the ‘Extra-Cell %’ of that pure component through the Reactions tab. In that case, the ‘Sorption %’ value of that component in the liquid product stream will be calculated by the program when you run the M&E balances.
