PSRK Matrix 2024

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 2024 in the consortium. Click or tap the diagram to see more details.
