These equations include those of Bene dict-Webb-Rubin (BWR), Soave (SRK), who extended the remarkable Redlich-Kwong equation, and Peng-Robinson (PR). (13-3) have been restricted to mixtures of nonpolar compounds, namely, hydrocarbons and light gases. Until recently, equations of state that have been successfully applied to Eq. Consistent equations for enthalpy can similarly be derived. ![]() Where the mixture fugacity coefficients L for the liquid and ,V for the vapor are derived by classical thermodynamics from the PVT expression. When a single pressure-volume-temperature (PVT) equation of state is applicable to both vapor and liquid phases, the formulation used is Preferred analytical correlations are less empirical in nature and most often are theoretically based on one of two exact thermodynamic formulations, as derived in Sec. 13-14 K values (K = y/x) in light-hydrocarbon systems.
