The group contribution methods UNIFAC and Modified UNIFAC (Dortmund) and the group contribution equation of state PSRK are used world-wide for the synthesis and design of separation processes and a large number of further applications of industrial interest. They belong to the most important thermodynamic models for the daily work of a chemical engineer and were therefore integrated in most of the available commercial simulators (e.g. Aspen Plus®, CHEMCADTM, Pro/II®, HYSIM, ProSim,...).
At the moment there are no governmental funds available, which would be required for a thorough revision, extension and further development of these methods. To improve the situation a company consortium was founded at the University of Oldenburg to support the further development of these models. Therefore the revised and extended group interaction parameters will be given only to the sponsors of the UNIFAC project and will not be available via the different process simulators ( the sponsors receive the implementation files for Aspen Plus, Chemcad, Pro/II®, Dynsim and ROMeo).
The direct sponsoring by the companies even includes the possibility to influence the direction of further developments, so that the models will definitely become more and more attractive for the chemical industry.
The aim of the consortium is the further development of the Group Contribution Methods UNIFAC, Modified UNIFAC (Dortmund) and PSRK.
