A Modified van der Waals Mixture Theory for Associating Fluids: Application to Ternary Aqueous Mixtures [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2012
In this study a simple and general chemical association theory is introduced. The concept of infinite equilibrium model is re-examined and true mole fractions of associated species are calculated. The theory is applied to derive the distribution function

Extractive Distillation Process Combined with Decanter for Separating Ternary Azeotropic Mixture of Toluene-Methanol- Water

Chemical Engineering Transactions, 2017
The mixture of toluene-methanol-water is difficult to separate because of the formation of toluene-methanol and toluene-water azeotropes. Extractive distillation process with two-column decanter (EDTCD) was improved to separate the system.

Extraction of Monocyclic Aromatic Hydrocarbons From Petroleum Products Using Sulfolane as Industrial Solvent

Al-Khawarizmi Engineering Journal, 2010
Liquid – liquid equilibria data were measured at 293.15 K for the pseudo ternary system (sulfolane + alkanol) + octane + toluene. It is observed that the selectivity of pure sulfolane increases with cosolvent methanol but decreases with increasing the ...
