PSRK Matrix 2018

For the description of systems with supercritical compounds cubic equations of state (EoS) can be applied. Beside phase equilibria equations of state at the time provide also other thermodynamic properties (enthalpies, densities). The group contribution Equation of State PSRK combines the Soave-Redlich-Kwong (SRK) equation with the original UNIFAC model and allows an accurate prediction of phase equilibrium in a wide temperature and pressure range. The range of applicability was extended by introducing 30 gases as new main groups.

The diagram in this page shows the development of the groups and parameters of the Predictive Soave-Redlich-Kwong (PSRK) method from 2004 to 2018 in the consortium. Click or tap the diagram to see more details.

A description of PSRK is available in Wikipedia, see German and English article.

16th Joint DDBST User and UNIFAC Consortium Member Meeting Closed

The 16th joint DDB user and UNIFAC consortium member meeting took place on Tuesday, September 18th

We were very happy that we could welcome participants from a wide variety of companies and countries. We had several customer lectures together with several talks of our own people.

We would like to thank all participants for their contributions and hope we will keep in touch and see most of this year's participants also in the next year.
