SimuSage development at SMS Demag

Why would SMS Demag start developing SimuSage?

• Integrated Thermodynamic Databank Systems such as
  FactSage are great tools for point calculations,
  range calculations, phase diagrams, etc.
• What about processes, i.e. multiple reactors
  interconnected via streams? Recycle/feedback
  streams? Dynamic behaviour? A library of other
  unit operations like mixers, splitters, heat
  exchangers?
• What about doing this quickly, with a minimum
  amount of coding? Including a user interface that
  somebody other than the developer can use?
• And what if you want to give your ready-made
  simulation to somebody else?

What is SimuSage?

• SimuSage is a ChemApp-based set of Delphi
  components for process simulation (flowsheeting)
  tasks

• ... is a set of visual components
• Visual programming
• RAD (Rapid Application Development)

SimuSage ...

• ... is ideal for distributing ready-made
  simulations
• Delphi produces EXEs (just add ChemApp DLL)
• end user does not need Delphi

8
Available thermochemical data All data managed
by FactSage, plus more

• Compound databasesgt 4500 pure substances and
  stoichiometric compounds
• Solution databases
• Oxides
• Salts
• Metallic alloys
• Light and noble metals
• Steel, copper and lead alloys
• Ultrapure silicon
• Aqueous solutions
• Nuclear materials
• Pulp and paper

Last but not least...

• Join our GTT workshop in June!
• Herzogenrath, last week in May or first week in
  June, 2008
• user presentations
• 1-day FactSage and SimuSage hands-on sessions
• For details, see our GTT-News newsletter at
  www.gtt-technologies.de
• Look for the ChemApp and Simusage articles in the
  special IJMR issue 98(10) of this fall
