HYSYS OLI Interface. Reference Guide

Aspen Technology, Inc., 2003. — 226 p.The HYSYS OLI Interface package is based on OLI Systems software that provides clients with a theoretical framework, databases, data regression techniques, and applications software that comprehensively and accurately simulates and predicts electrolyte systems.
The HYSYS OLI Interface approach allows you to access OLI components and the OLI Engine, which is distinguished by the following unique elements: complete speciation. The OLI model predicts and considers all of the true species in a solution, and accounts for these in the computations; robust standard state framework. Based on the Helgeson equation of state and parameter regression and proprietary estimation techniques, the OLI model provides accurate
equilibrium constants and other standard state properties over the broadest possible aqueous range of conditions; activity coefficients for complex, high ionic strength systems. Based on the combined work of Bromley, Zemaitis, Meissner, Pitzer, and OLI technologists, OLI models can predict
behaviour under real world conditions; comprehensive databank. The Databank covers 79 inorganic
elements and their associated compounds and complexes, and over 3000 organic chemicals. For customized coverage of clients' chemistry and private databanks, contact OLI Data Service; thermo-physical properties. OLI has developed unique chemical-physical based models to compute thermodynamic and transport properties for complex aqueous environments and are
provided by the HYSYS OLI Interface.
