Péneloux's mixing rules: 25 years ago and now

► Both PR 2SRK and Soave et al.’s model stem from Péneloux et al.’s work on predictive equations of state. ► The only difference between both these models is the way used to express by group contributions the binary parameters involved in the excess function of the mixing rules. ► Since PR 2SRK and...

Summary:► Both PR 2SRK and Soave et al.’s model stem from Péneloux et al.’s work on predictive equations of state. ► The only difference between both these models is the way used to express by group contributions the binary parameters involved in the excess function of the mixing rules. ► Since PR 2SRK and Soave et al.’s models share similar foundations, the comparison carried out in this paper points out that they can predict fluid phase behaviour with more or less the same accuracy.
