PSRK — Predictive Soave-Redlich-Kwong

The Predictive Soave-Redlich-Kwong (PSRK) method is a group contribution equation of state (GC-EOS) that combines the Soave-Redlich-Kwong equation of state (Soave, 1972)[6] with the UNIFAC method[1].

See SRK — Soave-Redlich-Kwong equation of state and UNIFAC — UNIQUAC Functional-group Activity Coefficient method for reference.

The PSRK method is also known as the SRK-Holderbaum-Gmehling method.
