Abstract
AbstractA new cubic equation of state with three parameters is developed. The substance‐dependent critical compressibility factor, ζ, and the temperature‐dependent parameter, α, were correlated in terms of the acentric factor and reduced temperature. The P‐V‐T relationships, vapor pressures, volumes, and enthalpy departures of pure substances, and the compressibility factors, enthalpy departures, and vapor‐liquid equilibria of mixtures were calculated with the proposed equation. Comparison of the calculated results with experimental data shows that the proposed equation is accurate enough to be applied for design purposes.
