✦ Synopsis

Some methods for correlating multicomponent vapor-liquid equilibria by using an equation of state are examined. A simplified Morbidelli-Carri algorithm is proposed as the best tool for an eight parameter equation previously reported in Chem. Engng Sci. The possibility of reducing the empirical parameters of this equation from eight to five and the binary interaction parameters from three to two is also discussed. Both these models have been applied to several binary and ternary mixtures of polar and apolar compounds in a wide range of pressure and temperature. The proposed method also correlates systems exhibiting miscibility gaps or containing quanta1 gases.
