:: New Simulation Tool HSC Chemistry 7.0 for Process Engineers and Research Scientists

Modelling and simulation supply the answer to navigating the ever-growing oceans of data that threaten to engulf us. The new HSC Chemistry 7.0 from Outotec Research Oy, of FIN-28101 Pori, Finland is a straightforward simulation tool designed to guide process development and research scientists.

HSC is a software program for process flowsheet simulation, which also contains 22 other calculation modules displayed as options in the main HSC menu, and 12 databases together with extensive thermochemical, heat transfer and mineralogical data. HSC Chemistry 7.0 is compatible with Windows Vista, Vista 64 and Windows 7.

New features

The Flowsheet Module of HSC Chemistry 7.0 has four different modes - Particles, Reaction, Distribution and Experimental - with new, dedicated tools. There are new drawing features, high-resolution icons, a new table facility, new page and layer properties, new spreadsheet features, and new Excel Wizards with more commands, as well as Mass Balancing and Data Reconciliation routines.

The new Unit Icon Library comprises 515 high-resolution icons that have been created to visualize process flowsheets. There are nine new Add-In Functions - StreamSM, StreamGM, StreamEQA, StreamXArray, RecoveryXArray, ProgenyStream, ComminutionProductPSD, CubicSpline, and ERF.

During mineral set-up there is direct access to the HSC Mineral Database, complete with its new Mineral Database Browser. There are improved liberation data-processing tools as well as enhanced unit models of mineral processing equipment to provide more detailed data on particle size, density, composition and distribution.

The new Distribution mode makes it possible to work with high temperature process models. The new Experimental mode enables the visualization of stream properties and the development of experimental data tables.

Updated modules

Three of HSC Chemistry 7.0ís modules have been updated: the Balance Module, which now performs Automatic entropy (T * S) and Gibbs energy (G) balance calculations; the Equilibrium Module now offering a more robust Gibbs Energy Minimization routine, and the MW Module with new H, S and Cp Estimates.

The Aqua Module has been developed and it incorporates a new Aqueous Solution Property Estimator to estimate non-ideal electrolyte solution properties, like activity coefficients and enthalpies, which may be used in the Equilibrium module or in process models.

Enhanced databases

All calculation modules automatically use the same thermochemical database, which contains enthalpy (H), entropy (S) and heat capacity (C) data. This H, S and Cp Database has been comprehensively enhanced to include over 4000 new species, and the existing data on 4700 species have been updated. The total number of species now exceeds 25 000. The data is based on the massive amount of experimental work carried out over the last hundred years in laboratories all over the world.

The Mineralogical Database has been hugely increased - from 3581 to 13346 minerals with better integration with process models.

Outotec Research Oy arranges general and in-house training courses on HSC Chemistry 7.0
