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

Related Links: PHREEQC SysCAD Project Workflow

Available from Build 139.30807.

General Description

The PHREEQC Feeder model allows the user to specify a feeder using PHREEQC species. After PHREEQC equilibrium calculation, reverse mapping is completed to form SysCAD stream which becomes the outlet product stream. The user enters the mass or molar makeup of the 'Feed' stream, and the unit will then determine the equilibrium conditions of the resulting stream at the user defined temperature/enthalpy and pressure.

This model can act as a source of material, similar to the standard Feeder-Cross Page Connector model. The user sets the Required Flow from the unit, the Temperature and Pressure AND the species composition, on the DInput page.

If an outlet stream is not connected, then the model acts just like the corresponding PHREEQC Direct Calc model.

Notes

  1. The user MUST have added and configured a PHREEQC Model Configuration unit in the SysCAD project before this unit can function.
  2. The user MUST have installed a version of PHREEQC on their computer to make use of the PHREEQC functionality in SysCAD. Please see https://www.usgs.gov/software/phreeqc-version-3 for more information.

Model Theory

The PHREEQC Feeder Model uses the PHREEQC algorithms and data to determine the status of the aqueous solution.

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

The PHREEQC Feeder can be incorporated into a SysCAD flowsheet, it can be connected with SysCAD inlet and outlet streams.

  1. User connects the PHREEQC Feeder with SysCAD input streams,
  2. 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.
  3. The PHREEQC Feeder calls the PHREEQC algorithms to determine the status of the mixture using the converted PHREEQC "input" data.
  4. The PHREEQC results are displayed in the "output" tab using PHREEQC species.
  5. The results are converted back into SysCAD species. Please see Species Mapping for more information.

NOTES:

  • 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:

  1. Make sure the project contains at least one of the PHREEQC Model Configuration model, and the model is loaded with the correct PHREEQC database you would like to use for the PHREEQC Feeder.
  2. On the PHREEQCFeeder tab page, configure the model - methods, pressures, sub-models (if applicable)
  3. On the DInput tab page, specify the composition of the feed. Note: Flow, temperature and pressure can also be specified on this page.
  4. On the TCE tab page, select the correct ChemModel (to match step 1) (Note: In older builds, this selection was made on the PHREEQCFeeder tab page).
  5. Select other TCE options (Bypass, VLE, CFE, etc.)
  6. Choose the Target Calculation OpMode and fill in the required information based on the operation mode selection.
  7. Perform an equilibrium calculation by pressing Solve in SysCAD.
  8. The Results are displayed in the PHREEQCResults and Output tabs.
  9. Check and fix any species mapping issues. (PHREEQC resulting species may change if the operating conditions change, so it is likely a change of temperature or feed composition will result in different PHREEQC species.)
