Cake Wash: Solubility Tab

This tab appears on the interface dialog of the following operations:

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

○ Is Particulate ? Check the box next to a component retained in the cake to indicate that the corresponding component is particulate.	<No>	Yes/No
○ Is Soluble ? Check the box next to a component retained in the cake to indicate that the corresponding component is soluble.	<No>	Yes/No
◙ Solubility (g/L) The solubility of a component retained in the cake to the wash solvent.	0.0	Positive
◙ Approach to equilibrium (%) Factor that determines the degree that the mass transfer of a soluble cake component to the wash solvent approaches phase equilibrium.	0.0	0-100
◙ Loss (%) The percentage of a soluble cake component that is transferred to the wash stream	0.0	0-100

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 Cake Wash: Modeling Calculations.

This dialog allows the user to specify solubility data for the retained components. (Note that even though all components are available in the table, solubility calculations will be performed only for the retained components.)

•Is Particulate ?...

Particulate components are defined by the previous filtration operation in the procedure (if any) and the flag cannot be modified. Otherwise, the components should be characterized as particulate by the user.

•Is Soluble ?...

Check this box for any retained component that is soluble in the wash stream.

•Set Solubility Data Option...

If the Set Solubility Data option is chosen, the user should set the solubility in the wash stream (g/L) and the approach to equilibrium (%) for the soluble components. The solubility represents the maximum solubility a component can have in the wash stream (i.e. if the approach to equilibrium is 100%).

•Set Loss Data Option...

If the Set Loss Data option is chosen, the user should set the Loss (%) for the soluble components. This represents the % of the retained components that are lost in the wash stream.
