German-Finnish joint venture provides software to handle chemical and thermodynamic calculations in Excel
The flexibility and practicality of spreadsheet applications have been combined with the thermodynamic and simulation capabilities of Gibbs Energy minimisation to create ChemSheet ®, a new software product with a multitude of uses in the simulation of process chemistry. Its application is appropriate for metallurgical, chemical and process industries as well as for geochemists and environmentalists. Also, there is a special appeal to those in universities and chemical education.
ChemSheet allows rigorous chemical and thermodynamic calculations to be computed within the familiar environment of Microsofts Excel® spreadsheets. Simulation of multi-stage process chemistry with heat and mass transfer or reaction kinetics is also possible. Even though ChemSheet uses complex numerical procedures with extensive thermodynamic data linked with appropriate reaction kinetics, it produces the results on a simple Excel spreadsheet and thus makes the simulation accessible to the general user.
ChemSheet applies the ChemApp thermodynamic program library, which handles repetitive complex equilibrium calculations for a diverse range of chemical and thermodynamic applications. ChemApp can be used to calculate both the composition and the thermodynamic properties of a multi-phase, multi-component system at given conditions. With ChemSheet, versatile phase-mapping and property-target calculations can also be done.
The applications range from analysis of laboratory and environmental data to practical process simulation and design. In ChemSheet each process chemistry model is formatted to a practical worksheet from which calculations are made via Excel menus the user handling results through Excel tables or charts.
Through the application of this software, there is considerable timesaving between calculation and presentation. In a practical simulation project, with the chemical and equilibrium calculations executed, extensive additional work is needed to produce the evaluation of the results. This has to be done in terms of conversion percentages, efficiency, energy consumption per unit and, finally, unit cost. ChemSheet, through its MS-Excel interface, allows simulation directly from the worksheet and generates the resulting data with the
versatile mathematical and graphical tools offered by this program.
Thermodynamic simulation packages are rarely used in practical engineering and process design because of their perplexing interfaces or need for specific programming. ChemSheet is therefore the answer for those who wish to manipulate process chemistry or metallurgy in a simulated environment while working on a familiar worksheet program in connection with their other Windows® applications.
As each application within ChemSheet is a specialised product, it is appropriate for a full range of users. Those who are unfamiliar with thermodynamic science will find it useful for engineering purposes or research, even in small businesses. Such applications which fall into this category could be phase mapping of metals and alloys, even ceramics, for annealing and sintering; examining the behaviour of mercury in combustion processes and flue gases; studying the precipitation of molybdates or other trace elements in the lime cycle; or the pH and electrolyte chemistry of process solutions.
For those who are familiar with multi-phase thermodynamics, the software allows for a multitude of thermochemical applications using the most common Excel spreadsheet techniques, such as phase mapping in complex systems and target calculations or extensive property balancing to examine heating value/temperature relations or precipitation/dissolution conditions.
The software is the product of a joint venture between GTT Technologies Inc (Germany) and VTT Chemical Technology (Finland). Through GTT, ChemSheet provides the ChemApp thermodynamic library as well as the necessary thermodynamic data files, which are already marketed separately. The ChemSheet/ChemApp combination permits the construction of multi-phase and process chemistry models. VTT provides the Excel connection as well as the time-dependent process simulation features.
