Improved Chemical Process Simulation

The 8.2 version includes infrastructure upgrades and enhancements that address the emerging needs of the hydrocarbon and chemicals processing industries. It can now be used on Microsoft Vista Enterprise & Business operating systems. PRO/II 8.2 includes improvements for modeling heavy oils and electrolytic systems and for generating pure component properties. It improves heavy-oils modeling with the addition of a new liquid viscosity prediction method that prevents viscosity from being skewed by the heaviest petroleum component. The software has also integrated the Mixed Solvent Electrolyte model, capable of reproducing speciation, chemical and phase equilibria, applicable to water-organic-salt systems and aqueous solutions from dilute to the fused-salt limit. It is also integrated with ProPred, a property prediction tool from the Computer Aided Process-Product Engineering Center of the Technical University of Denmark that allows pure component properties to be predicted from structure based on a multi-level group contribution method. It can be used directly with PRO/II software.Invensys Process Systemswww.invensys.com469.737.3917
