Template:Build139 New TPS Addons

From SysCAD Documentation
Jump to navigation Jump to search

The following new TPS (Third Party Software) Add-ons all relate to flexible integration in SysCAD plant models of third party software performing detailed equilibrium and thermodynamic property calculations. The direct integration of these specialist software programs in SysCAD provide a significant range of new and detailed applications in the SysCAD flowsheet simulator for a range of pyromet, hydromet and aqueous chemistry systems.

These add-ons were originally released as a BETA version in Build 138. They have been significantly improved and new unit models added in Build 139. PHREEQC and ChemApp add-ons are no longer a BETA version.

Each add-on comes with the following improved models. These were originally released as BETA versions in Build 138:

  • Model Configuration - Used to define and view various options for the selected TPS database, including management of mapping of SysCAD species list to species list used in TPS.
  • Direct Calc - Stand alone unit model to perform side calculations using TPS for predicting chemistry equilibrium conditions and properties on a user defined TPS stream.
  • Side Calc - Stand alone unit model to perform side calculations using TPS for predicting chemistry equilibrium conditions and properties on a SysCAD stream in the current project. New for Build 139 is the ability to combine several streams/contents to be evaluated in a single Side Calc model.
  • Reactor - Include this model in a SysCAD stream to use TPS to calculate predicted outlet conditions. Functionality is similar to SysCAD Reaction Block and FEM where for a given feed, reactions occur with optional heat exchange. The model can be configured in a number of ways for different purposes.

PHREEQC Add-On

See PHREEQC Add-On for a description of this new add-on. PHREEQC is a computer program that is designed to perform a wide variety of aqueous geochemical calculations. It is developed and maintained by the United States Geological Survey www.usgs.gov/software/phreeqc.

New in Build 139 is the ability for the user to enter estimated LogK values directly into SysCAD. See LogKAdjust page for more information.

ChemApp Add-On

See ChemApp Add-On for a description of this new add-on. ChemApp is a computer program for thermodynamic phase equilibrium calculation primarily in pyrometallurgy using ChemApp and FactSage. It permits the calculation of complex, multicomponent, multiphase chemical equilibria and their associated extensive property balances. ChemApp [1] is developed and maintained by GTT-Technologies [2]. FactSage [3] is by CRCT ThermFact Inc [4] and GTT-Technologies [5].

AQSol Add-On

See AQSol Add-On (currently in BETA) for a description of this new add-on. The AQSol program can be used for general phase equilibrium calculations for aqueous solutions. It is developed and maintained by Aqueous Solutions ApS, Søborg, Denmark www.phasediagram.dk.

General TPS Improvements

  • Multithreading implemented for all.
  • Increased configuration options, including number of engines and minimum water content.
  • Individual phase deportment information now available for all models.

New TPS Unit Models

  • PHREEQC Evaporator / AQSol Evaporator - Uses PHREEQC/AQSol to calculate the equilibrium conditions and properties. May be used as a Crystallizer. Allows embedded HX and slurry separator. Can be used as part of a Flash Train.
  • PHREEQC Flash Tank / AQSol Flash Tank - Uses PHREEQC/AQSol to calculate the equilibrium conditions and properties. May be used as a Crystallizer. Can be used as part of a Flash Train.
  • PHREEQC Reverse Osmosis Unit / AQSol Reverse Osmosis Unit - Uses PHREEQC/AQSol to calculate the equilibrium conditions and properties. The user may specify the yield and efficiency of the process, as well as the outlet pressure requirements.
  • PHREEQC Solvent Extraction - Uses PHREEQC to calculate the equilibrium conditions and properties. The Solvent Extraction unit will mix perfectly all the input streams, complete species transfer across phases, then separate the output based on individual phase or density.
