New version of steady-state simulation improves chemical processes

Invensys Process Systems (IPS), a global technology, software and consulting firm, has released the newest version of SimSci-Esscor's PRO/II software, a steady-state process simulator used to design, analyse and improve chemical processes. In addition to the numerous infrastructure upgrades and enhancements that address the emerging needs of the hydrocarbon and chemicals processing industries, PRO/II simulation software can now be used on Microsoft Vista Enterprise & Business operating systems, and IPS has provided an updated install procedure and support for Microsoft Office 2007.

PRO/II 8.2 simulation software includes improvements for modelling heavy oils and electrolytic systems and for generating pure component properties. The PRO/II 8.2 simulator improves heavy-oils modelling with the addition of a new liquid viscosity prediction method that prevents viscosity from being skewed by the heaviest petroleum component. PRO/II 8.2 software has also integrated the Mixed Solvent Electrolyte model, the latest electrolyte model from OLI Systems, capable of reproducing speciation, chemical and phase equilibria, applicable to water-organic-salt systems and aqueous applications from dilute to the fused-salt limit.

The newest version of the software 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 and can be used directly with PRO/II software.

"PRO/II 8.2 software shows our dedication to both the hydrocarbon and chemicals processing industries. We have developed features for each industry, as well as introduced features and infrastructure upgrades that will enhance the user experience of all of our customers," said Joseph McMullen, PES product manager for IPS. "Our technological advancements in the area of modelling heavy oils truly set PRO/II simulation software apart from the competition, which continues to have issues accurately modelling heavy oils."

The new integration with Microsoft Vista Enterprise & Business operating systems and support for Microsoft Office 2007 means that IPS clients can now integrate simulation and modelling functionality and data more easily with other enterprise applications.
