Completely Stirred Tank Reactor Costing Method

Costing Method Parameters

The following parameters are constructed for the unit on the FlowsheetCostingBlock (e.g., m.fs.costing.cstr) when applying the cost_cstr costing method in the watertap_costing_package:

Description	Symbol	Parameter Name	Default Value	Units
Capital cost A parameter \(^1\)	\(A\)	`capital_a_parameter`	1246.1	\(\text{USD}_{1990}\)
Capital cost B parameter \(^1\)	\(B\)	`capital_b_parameter`	0.71	\(\text{dimensionless}\)

Costing Method Variables

There are no costing method variables unique to the CSTR.

Capital Cost Calculations

Capital cost is dependent upon the unit’s volume, \(V\), as shown in the equation below.

\[C_{cap,tot} = A * V^{B}\]

Operating Cost Calculations

There are no operating costs unique to the CSTR.
