Centritech Centrifugation: Oper. Conds 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

○ %Removed The removal percentage of feed stream particles.	0.0	0 – 100
○ Concentration Factor (Feed/Concentrate)	20.0	>= 1.0
○ Setup Time 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
◙ Centrifugation Time (h) The actual duration of the operation (per cycle). Note that this value is always set in Design Mode.	4.0	Positive
○ Power Type Indicates the power type that is used by the operation. Click on the list box to bring up a list of available power types in order to select one.	<Std Power>	Any Power Type
● Power (kW) The total power consumed for the operation (per cycle).	0.0	Positive
● Operating Throughput (L/h) The volumetric flow rate of the feed.	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 Centritech Centrifugation: Modeling Calculations.

•Process Time Options...

In Rating Mode (specified equipment capacity), the user has the option of setting either the centrifugation time or the Operating Throughput. In that case, the model calculates the time required to process a certain amount of material.
