摘要: The equation of state which combines Peng-Robinson EoS and the association term SAFT model was presented for describing thermodynamic properties phase behaviors associating fluids. resulting EoS(Peng- Robinson-Plus-Association) is not cubic with respect to volume contains five pure compound parameters. 5-param- eters chemical compounds were estimated correlations both saturated vapour pressures liquid vol- umes alcohols, primary amines, carboxyl acids water. A method reduce number adjustable parameters from three considered, then 3-parameters obtained. This 3- parameter maintained good volumes. Additionally proposed in this work applied calculations vapour-liquid equilibria binary mixtures containing chemicals, result showed a agreement experimental data all except ethanol/water system, examined work.
