Mixer-Settler Extractor: Equipment Tab

Variable Definitions, Ranges and Default Values

The following table shows the meaning of the variables appearing in this tab, as well as their default values and their generally acceptable range. Note that due to the manner by which the variables are used by the sizing and costing equations, the range of acceptable values may be further reduced.

Variable	Default Value	Range

◙ Rated Throughput The throughput of the mixing-settling tanks.	0.0 L/h	Positive
◙ Max Throughput The maximum throughput that a unit of this type is available for purchase in the market.	200,000 L/h	Positive
◙ Mixer Volume The mixing tank volume.	0.0 L	Positive
◙ Settler Volume The settling tank volume.	0.0 L	Positive
○ Number of Stages The number of extraction stages.	1	Positive

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

Sizing: Design Mode

In Calculate (Design Mode), the user specifies the Maximum Throughput and the system computes the Number of Units, Number of Stages, Rated Throughput, Mixer Volume and Settler Volume. For more information on the sizing of this unit, see Mixer-Settler Extraction: Modeling Calculations.

Sizing: Rating Mode

In User-Defined (Rating Mode), the user specifies the Number of Units, Number of Stages, Rated Throughput, Mixer Volume and Settler Volume.

Costing

The equipment purchase cost is based on the mixer tank volume and the settler tank volume. It is supplied by the built-in model assuming as material of construction SS316 and it is a affected by the number of extraction stages.
