Application of conformal solution theory to vapor-liquid equilibrium

[摘要] Several different variation of the binary-K expansion method are presented, based on the conformal solution theory expansion of Gibbs free energy by Byers Brown. First and second order terms are included and several kinds of shape factors are used. A variation using the correction termsof Pitzer-Curl correlations is also given. Vennix's methane equation of state and Starling's ethane or propane equations of state are used as vapor (methane) and liquid (ethane or propane) references. Equations to evaluate thethermodynamic properties required, based on those equations, are given.Results of each one of the methods are presented and compared against experimental values.
