New Models and Add-Ons Model Improvements Model Enhancements

New Models:

  • Solids Recovery Unit :
    • suitable for modelling solid recovery processes (eg: mags & spirals)
    • allows Concentrate, Middlings (optional) and Tailings as outlets
    • Solids Recovery can be based on grade or PSD

New Sub-Model:


New Add-Ons:

Significantly enhanced and detailed Pyrometallurgy and Aqueous Chemistry applications possible with:

  1. Model Configuration
  2. Direct Calc
  3. Side Calc
  4. Reactor
  • These add-ons are currently in BETA release, please contact us for more for information.
  • Feeder
    • New operation modes - designed to simplify data entry based on material type.
      Eg: Steam mode will contain only Steam on the DSp tab
    • The simplified data entry reduces possibility of incorrect data entry.
    • The General Operation mode retains the full functionality and flexibility.
    • The new Operation modes work with Demand functionality.
      Click here for an example.
  • Thermocompressor
    • New option to specify Discharge Pressure
    • demand calculation based on Primary or Secondary Steam inlets
  • Belt Filter:
    • Added option for user to load or save the wash loss data.
  • Feeder
    • New option (ConnectBlocked) to exclude feeders from crosspage connection list.
  • FEM Reactor:
    • New display options for analysis.
    • Improved messages and information for failed convergence.
    • Miscellaneous solver improvements for different conditions.
  • Flash Tank
    • Improve error reporting when feed saturation pressure is too high.
  • Makeup Block
    • new selections for Solids, Liquid and Vapour Species
    • better ranging of inputs.
  • Precipitator3:
    • Additional growth rate tuning factor.
    • new option to include/exclude nucleation yield in bound soda calculations.
    • New options in dynamic for managing changes in tank volume.
  • Unit models with feed Makeup Block
    • now allow the makeup to be the only source of material to the unit.
User Interface Improvements Other Improvements Project Upgrade And Changes that Affect Results
  • View - PlantModel- Project tab - added new Project Information fields
    for project description and information, including two hyperlinks.
  • New Menu Command View - Project Description
    Tied to the hyperlink entered in PlantModel - DescLink.
    • For distributed example projects, using this command will open
      the SysCAD help page for the project description.
  • New Menu Command Help - Example Projects
    Opens Example Projects help page, providing example project description.
  • New option added to Insert Unit and Change Unit to "Show All"
    Allow display of all unit models in dlls without first editing the configuration file.
  • Species Filter - Expanded filter to display species with the largest flows.
    • display can be based on largest flows or minimum mass fraction.
  • Increased limit on number of Individual Phases allowed from 32 to 250.
  • Added new Specific Heat equation NASAGlenn_Cp equation.
  • Additional tests and warnings during project load for inconsistent Entropy data.
  • Option in the Edit Configuration step 2 to perform entropy data check on project load.
  • Additional columns in the $SDB -Thermo1 and $SDB -Thermo2 tabs for H25 and S25 values.
    • Warnings will be given for species with missing H25 and S25 data.
  • Added Gibbs Free Energy to stream display under Entropy section.
  • Implemented support for larger numbers of species with PSD in projects.
  • Potash Properties Utility utility updated with 64 bit version now available.

"Tutorial & Examples"

  • Updated Tutorial documentation. Please see Tutorial in the Help documentation.
  • Example Projects distributed with SysCAD have been updated
  • New Example projects have been added. (eg: SOP)
  • Menu command Help | Example Projects will open the Example Projects help page.

"Under the Hood" Changes

  • Reduced memory use for projects allowing even larger projects with more species.
  • Moved Belt Filter, Solvent Extraction Unit and Washer from Separ1.dll to Separation.dll.
  • Compiled with Microsoft C++ 2017.
  • Significantly enhanced SMDK (SysCAD Model Developers Kit).
  • Various general and solver speed improvements.

Changes that may Affect Results

  • Thermocompressor 1D Model - S&K Data & Full Steam 1D Model methods:
    • using excess energy to either superheat or condense steam.
    • may result in a reduced heatflow & changed final product T.
  • Thermocompressor model improvements
    • HeatFlow - sign reversed to correctly report Energy Out - Energy In.
  • Makeup Block changes:
    • Selection of elements is limited to what is present in the project.
    • If "invalid" elements were previously selected,
      the user will receive a warning on load and it will appear
      as a blank selection in the makeup block configuration.
  • Entropy value reporting may show different value if Entropy data is missing in the species database.

Project Upgrade

  • Project will be auto-upgraded to use the new "Tear" formats.
  • Precipitator3 Bound Soda Hunter & Fixed% Methods
    • Option to use corrected calculation methods in 138.
      Using the corrected calculations methods may require model returning
      for bound soda and bound organics precipitation values.
  • Preciptitator3 - Agglomeration Cutoff Fixes
    • Option to use corrected calculation methods in 138.
      Using the corrected calculations methods may require model returning
