Correlation for fitting multicomponent vapor-liquid equilibria data and prediction of azeotropic behavior

Correlation equations for expressing the boiling temperature as direct function of liquid composition have been tested successfully and applied for predicting azeotropic behavior of multicomponent mixtures and the kind of azeotrope (minimum, maximum and saddle type) using modified correlation of Gib...
