Latest SysCAD Version: 25 October 2024 - SysCAD 9.3 Build 139.36522

Related Links: PHREEQC SysCAD Project Workflow

Formally released as part of Build 139 (first available as BETA version in Build 138). The PHREEQC SysCAD TCE option and models documentation is for the latest version of SysCAD.

General Description

The PHREEQC Side Calc model allows the user to 'call' the PHREEQC solver to determine the state of a defined SysCAD stream/s. The user defines the SysCAD stream/s of interest, and the unit will then determine the equilibrium conditions of the resulting stream at the user defined conditions such as temperature or enthalpy. This is similar to the use of the PHREEQC Reactor using the Side Calc model option.

The model has no links to any other models in SysCAD. Therefore, this model is not a part of any SysCAD network, but is a stand-alone calculation that allows the user to check the status of a stream.

Notes

The user MUST have added and configured a PHREEQC Model Configuration unit in the SysCAD project before this unit can function.
Installation of PHREEQC is not required to use the PHREEQC functionality in SysCAD. If the user wishes to install PHREEQC, please see https://www.usgs.gov/software/phreeqc-version-3 for more information.

Diagram

The diagram shows the default drawing of a PHREEQC Side Calc unit model. For side calculations with multiple incoming streams and containers, the combined stream pressure will be set to the lowest pressure of the incoming streams or containers that contain a flow or mass, respectively.

Inputs and Outputs

There are no connections to this unit.

Model Theory

The PHREEQC Side Calc Model uses the PHREEQC algorithms and data to determine the status of the aqueous solution in the defined stream/s.

Mapping of the SysCAD to PHREEQC streams is done via Species Mapping.

The PHREEQC Side Calc model allows the user to 'call' the PHREEQC solver to determine the state of a defined SysCAD stream/s. The model has no links to any other models in SysCAD.

User defines the stream/s to be analysed by the PHREEQC Side Calc model.
The SysCAD feed stream(s) using SysCAD species is converted into PHREEQC "Input" using PHREEQC Species. The species mapping is defined in the corresponding PHREEQC Model Configuration unit model.
The PHREEQC Side Calc calls the PHREEQC algorithms to determine the status of the mixture using the converted PHREEQC "input" data.
The PHREEQC results are displayed in the "output" tab using PHREEQC species.
- The results are NOT converted into SysCAD species.

NOTES:

The side calculation mixed feed stream pressure is calculated as the minimum pressure of all incoming streams.
The Input, Output and Diff tab pages are displayed using PHREEQC species, as defined in the database (.dat) specified in the corresponding PHREEQC Model Configuration unit model.
The species used in the SysCAD project are shown on the optional Sp pages, shown as part of the QFeed, QBypass, QUnmapped, QRxnProdBypass and QProd pages.
The calculations performed are similar to using PHREEQC directly, except the contents of the SysCAD stream are mapped to equivalent PHREEQC species using the settings defined in the PHREEQC Model Configuration unit model. Please see https://www.usgs.gov/software/phreeqc-version-3 for more information.

Calculation of Osmotic Pressure

PHREEQC calculates the activity of water, which is then used to calculate the osmotic pressure by the Van't Hoff formula. The Van't Hoff formula is:

[math]\displaystyle{ \Pi=-\frac{RT}{\overline{V}}ln(a_w) }[/math]

where [math]\displaystyle{ \Pi }[/math] is the osmotic pressure, [math]\displaystyle{ \overline{V} }[/math] is the partial molar volume of water (ideal), and [math]\displaystyle{ a_w }[/math] is the activity of water (mole fraction basis).

WorkFlow

The suggested workflow for configuring the model is:

Make sure the project contains at least one of the PHREEQC Model Configuration model, and the model is loaded with the correct PHREEQC database file you would like to use for the side calculation.
On the PHREEQCSideCalc tab page, type in the name of the SysCAD stream/s or content you wish to evaluate (e.g.: P_001.Qo OR TNK_001.QFeed). In Build 139 or later, multiple streams with multipliers can be specified.
Choose when to perform the calculation.
On the TCE tab page, select the correct ChemModel (to match step 1) (Note: In older builds, this selection was made on the PHREEQCSideCalc tab page).
Choose the Target Calculation OpMode and fill in the required information based on the mode selection. (Note: In older builds, these selections were made on the PHREEQCSideCalc tab page).
Perform an equilibrium calculation by pressing the "Calculate" button on the PHREEQCSideCalc tab page or pressing Solve in SysCAD.
The Results are displayed on the PHREEQCResults and Output tabs.

Suggestions on how to use the results:

The PHREEQC Side Calc results can be used to assist with the configuration of with a SysCAD unit, normally with Reactions sub-model switched on. Based on the results of the PHREEQC Side Calc, the reaction and reaction extents can be configured to match results from the PHREEQC Side Calc. The user can use the Set Tag Controller to transfer PHREEQC Side Calc results to the SysCAD unit reaction block.
