Extractive distillation with salt in solvent

Rongqi Zhou, Zhanting Duan

Open publisher page 7 citations

Abstract

Extractive distillation with salt in solvent is a new process for producing anhydrous ethanol by combining the principle of “salt effect” and some traditional extractive distillation methods. Compared with the common extractive distillation the performance of solvent is improved, the recycling amount of solvent is reduced to 1/4 1/5, and the number of theoretical plates is reduced to 1/3. Energy consumption and cost of equipment are also reduced and continuous production is realized. High efficiency and low solvent wastage make this technique feasible.
