Released as a BETA version in Build 139.{{{AvailableBuildNo}}}.
General Description
The {{{TPS}}} Pond model is used in the Dynamic mode to emulate an Evaporation Pond. The user has the option to divide the pond into two layers, a bed where most of the solids settle and a clarified liquor layer for liquids, or consider the pond as a single layer. In any case, the concentration of the pore liquid in the bed layer and the concentration of the supernatant pond liquid is always equal and in equilibrium with the solids.
The {{{TPS}}} Pond model allows the user to 'call' the {{{TPS}}} solver to determine the state of a pond contents.
Notes
- The user MUST have added and configured a [[{{{TPS}}} Model Configuration]] unit in the SysCAD project before this unit can function.
- Installation of {{{TPS}}} is required to use the {{{TPS}}} functionality in SysCAD. If the user wishes to install {{{TPS}}}, please see {{{Webpage}}} for more information.

Model Theory
The {{{TPS}}} Pond Model uses the {{{TPS}}} algorithms and data to determine the status of the aqueous solution.
Mapping of the SysCAD to {{{TPS}}} streams is done via Species Mapping.
The {{{TPS}}} Pond can be incorporated into a SysCAD flowsheet, it can be connected with SysCAD inlet and outlet streams.
- User connects the {{{TPS}}} Pond with SysCAD input streams,
- The SysCAD feed stream(s) using SysCAD species is converted into {{{TPS}}} "Input" using {{{TPS}}} Species. The species mapping is defined in the corresponding [[{{{TPS}}} Model Configuration]] unit model.
- The {{{TPS}}} Pond calls the {{{TPS}}} algorithms to determine the status of the mixture using the converted {{{TPS}}} "input" data.
- The {{{TPS}}} results are displayed in the "output" tab using {{{TPS}}} species.
- If the {{{TPS}}} Pond is in Side Calc mode, the results are NOT converted into SysCAD species. (SysCAD stream outlet = sum of SysCAD inlet streams, no change will occur)
- If the {{{TPS}}} Pond is in Reactor mode, then 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 {{{TPS}}} species, as defined in the database (.dat) specified in the corresponding [[{{{TPS}}} 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 {{{TPS}}} directly, except the contents of the SysCAD stream are mapped to equivalent {{{TPS}}} species using the settings defined in the [[{{{TPS}}} Model Configuration]] unit model.
Workflow
The suggested workflow for configuring the model is:
- Make sure the project contains at least one of the [[{{{TPS}}} Model Configuration]] model, and the model is loaded with the correct {{{TPS}}} database you would like to use for the {{{TPS}}} Pond model.
- On the [[#{{{TPS}}}Pond_tab_page|{{{TPS}}}Pond]] tab page, configure the model - methods, pressures, etc.
- On the TCE tab page, select the correct ChemModel (to match step 1) (Note: In older builds, this selection was made on the [[#{{{TPS}}}Pond_tab_page|{{{TPS}}}Pond]] tab page).
- Select other TCE options (Bypass, CFE, etc.)
- Perform an equilibrium calculation by pressing Solve in SysCAD.
- The Results are displayed in the [[#{{{TPS}}}Results tab page|{{{TPS}}}Results]] and Output tabs.
- Check and fix any species mapping issues. ({{{TPS}}} resulting species may change if the operating conditions change, so it is likely a change of temperature or feed composition will result in different {{{TPS}}} species.)
