"ChemSheet combines the flexibility and practicality of spreadsheet applications with rigorous, multi-phase thermodynamic calculations. Each application is defined as an independent worksheet in Microsoft Excel®, in which the entire simulation can be done."

Nowadays, everybody uses spreadsheet programs like Microsoft Excel to collect information on e.g. process conditions (input, output, temperatures...). The great flexibility of spreadsheet programs allows easy basic physical modelling, e.g. of heat transfer, material transport or reaction kinetics. ChemSheet is an Add-In for Microsoft Excel that adds the ability of thermodynamic calculations by linking to ChemApp. This gives the user the ability to combine physical modelling in Excel with thermodynamic modelling in ChemApp. ChemApp is GTT-Technologies' programmer's library for the calculation of multicomponent, multiphase chemical equilibria and their associated energy balances.

The Excel Add-in ChemSheet was originally developed by VTT Chemical Technology, Finland, in cooperation with GTT-Technologies. Check out the various application examples that show how physical modelling and ChemApp calculations can be combined in a single Excel file!

ChemSheet is also available as ChemSheet Light - the free demo version of ChemSheet! Please find the package here

See ChemSheet Model calculation shown as animated gif files to see how easy it is to do different kind of case studies with ChemSheet.
