PREDICTION OF TERNARY LIQUID-LIQUID EQUILIBRIA USING THE NRTL AND THE UNIQUAC MODELS
The experimental binodal curve, tie line data, plait point data and the tie lines and plit point, calculated by liquid models for following six ternary liquid-liquid equilibria systems :
monochlorobenzene-water-acetone, cyclohexane-water-acetone, ethylacetate-water-acetone, chloroform-water-acetone, methylisobutylketone-water-acetone, and n-hexane-water-acetone were reported at 10℃.
Experimental tie line data were correlated to test consistency with Othmer-Tobias equation [15]
And those data were also correlated with the NRTL, the UNIQUAC, and the modified UNIQUAC models respectively and the parameters in each model were estimate to predict the value of tie lines by lease-squares methods.
