Abstract

The approach of using T, at ΔZ= Z^s _vZ^s ^L = 0.5 for a balanced representation of saturated volumes (V^s ^L and V^s ^{V^s
^L}( of pure components has been extended from non-polar fluids to water and ammonia. For the mixtures of these two compounds, the average absolute percentage deviation in the calculated V ^s ^L values is less than 2% without affecting the representation of vapor-liquid equilibrium values.
