New for Build 138. Currently in BETA - contact SysCAD for demonstrations or further information.

Overview

The AQSol program can be used for general phase equilibrium calculations and process simulations for aqueous solutions.

  • The AQSol software is developed and maintained by Aqueous Solutions ApS, Søborg, Denmark, (refer to www.phasediagram.dk for further information).
  • It is assumed that the user has some familiarity with the theory and use of the AQSol program.
  • This SysCAD add-on (in ScdAQSol.DLL) requires the SysCAD "Energy Balance" and "SMDK Runtime" add-ons. An AQSol License is also required.
  • AQSol must be installed on the computer for the add-on to work. AQSol001 can be downloaded (from www.phasediagram.dk/products) and installed and used for evaluation purposes with a standard SysCAD license.
  • To ensure SysCAD can access the AQSol DLLs, they should either be placed in SysCAD bin folder or their location should be in the system path.
    You can check the system path at: Control Panel > System Properties > Advanced > Environment Variables > Path > Edit...
  • AQSol is used in a flexible way in Unit or Control models at appropriate locations in a plant model. It is not implemented as a Species Properties Model.

Models

AQSol Unit models:

  • AQSol Model Configuration - Used to define and view various options for the selected AQSol database, including management of mapping of SysCAD species list to species list used in AQSol.
  • AQSol Direct Calc Model - Stand alone unit model to perform side calculations using AQSol for predicting aqueous chemistry equilibrium conditions and properties on a user defined AQSol stream.
  • AQSol Side Calc Model - Stand alone unit model to perform side calculations using AQSol for predicting aqueous chemistry equilibrium conditions and properties on a SysCAD stream in the current project.
  • AQSol Reactor - Include this model in a SysCAD stream to use AQSol 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.

Utility

Generate SysCAD database from AQSol Configuration File
