This approach makes it possible to simulate nearly any type of process. The HSC approach to process simulation is quite different from traditional simulation software. For example, the HSC-Sim module has built-in 'Sankey diagrams' to visualize the distribution of the elements and process variables. The HSC-Sim module also has high quality and versatile graphics capabilities and visualization. If users can use traditional HSC Chemistry and Excel software then they should be able to use the new HSC-Sim module too. The target in HSC-Sim development has been to create a simple but powerful simulation tool for the ordinary process engineer. The XLS files contain the calculation model of the unit, and these XLS-models may be reused in the other processes. These process files are always saved in the same file folder. The process model created using the HSC-Sim flowsheet module consists of one HSCSim file with a graphical flowsheet and one XLS file for each process unit. Units can be used together or separately and the calculations can be Excel- or DLL-based.

In the Distribution units the species are divided into elements and calculation is done with element distributions. Reaction-based units contain and calculate user-defined phases and chemical reactions. Particle units use calculation of inert particles in water with particle size distribution. The HSC-Sim module contains tools for users to build their model using three different modeling approaches: Particle, Reaction and Distribution. The HSC Add-In functions may be used to turn these independent calculation units into small HSC engines for thermodynamic applications. Each process unit is actually one Excel file. The custom-made variable list makes it possible to create many different types of process models in chemistry, metallurgy, mineralogy, economics, etc.

The HSC-Sim module consists of graphical flowsheet and spreadsheet type process unit models. The HSC-Sim module expands the possibilities for applying HSC Chemistry to a whole process made up of several process units and streams.

The traditional HSC Chemistry software was designed for various simulation and modeling applications based on independent chemical reactions and process units.
