Abstract
"A literature survey was carried out and the characteristics of promising solvents were carefully reviewed. Six solvents which showed promise as ethanol extractants were tested in this work. They were n-butanol, n-amyl alcohol, n-butyl acetate, isopropyl ether, butyl phthalate and propylene carbonate. A careful chemical analysis of solubility data was performed with a Varian model 3700 gas chromatograph. Six different ternary liquid systems were tested, the solubility envelope, the distribution coefficient Kd, and the selectivity [beta] were defined. The UNIQUAC model for experimental data correlation proved suitable for predicting the distribution coefficients and the selectivities of the ternary liquid-liquid systems. Two adjustable parameters per binary for the six different systems were obtained which facilitated further computer aided design, process optimization, and simulation. After a preliminary survey of the ternary liquid systems, the water-ethanol-butyl acetate system was chosen for the dual solvent extraction design. The mass balance and the energy consumption were calculated. The resulting design indicated the overall economics seem to be somewhat better than traditional distillation operations."--Summary.
