Critical evaluation of methane-hydrocarbon high-pressure experimental vapour-liquid equilibrium data using equations of state

Prediction of High‐Pressure Phase Equilibria using Cubic EOS: What Can Be Learned?

“…Usually, attempts to model the phase behavior of these systems are made by determining the optimum values for the binary adjustable parameters in the semi-empirical thermodynamic models applied (Marteau et al, 1997;Cebola et al, 2000). Though for equations such as SRK it is rather difficult to get sufficiently accurate results without t h e s e parameters, nevertheless the possibility has been conside r e d (Legret et al, 1984). Furthermore, in a recent paper (Polishuk et al, 2000b), we have demonstrated that accurate volume…”

Correlation of high‐pressure phase equilibria in the retrograde region with three common equations of state

“…Legret et al, 1984). We correlated these interaction parameters and used them for the multicomponent system, obtaining only fair results.…”
