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

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

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
