ChemSep is a column simulator for distillation, absorption, and extraction operations. Test-drive the equilibrium column model and convince yourself with the free ChemSep LITE with up to 40 components and 300 equilibrium stages using a database covering 400 chemicals. It combines the classic equilibrium stage column model with a nonequilibrium (rate-based) column model in one easy and intuitive interface.
v6.8 [Mar 2, 2011]
This new version features a continuous UnDo/ReDo in the GUI making it easier to correct mistakes. Where possible the user interface was simplified for more intuitive use. The number of tables, buttons and hints were extended. Using ChemSep columns in CAPE-OPEN compliant flowsheeting software was simplified with a new initialization dialog box. From v6.7 the Residue Curve Map generation was repaired and the flash algorithms and plot options for the VLE diagrams were much improved. Pseudo sidestreams can now be added and various bugs were patched (vapor viscosity, liquid heat capacity). Several new property methods were added (liquid density as well as vapour and liquid viscosities plus diffusivities). The Pure Component Data manager now has a units selection and temperature correlations can be fitted to data points. Packings data for Nutter/Raschig packings were updated and we implemented our own proprietary Maximum Useful Capacity (MUC) calculation.
