Reducing the energy demand of bioethanol through salt extractive distillation enabled by electrodialysis
… can be separated and concentrated aided by salt extractive distillation to directly produce fuel ethanol leading to significant energy savings. Techniques other than highly energy intensive evaporative salt concentration/crystallization and solids drying for recovering salt, which is used to …

Comparison of Multieffect Distillation and Extractive Distillation Systems for Corn-Based Ethanol Plants
… water/gal ethanol respectively using multieffect distillation. Karuppiah, et al use column rating and mathematical optimization methods and shortcut design models to design evaluate and optimize the energy and water consumption. In this work, we compare shortcut design and rigorous simulation …

Techno-economic assessment of jet fuel naphthalene removal to reduce non-volatile particulate matter emissions
… fuel naphthalene removal (via hydro-treatment or extractive distillation). We develop a stochastic discounted cash flow model based on the retrofit of existing US refineries with naphthalene removal systems, and compute costs from both societal and market perspectives. We find that the US-average …

Selective catalytic hydrogenation for industrial 1-hexene purification
… product of Fischer-Tropsch synthesis. A complex extractive distillation process is used to separate impurities from the product stream. A final polishing step by adsorption results in a significant loss of valuable alpha-olefin.

The design and construction of a liquid-liquid solvent extractor with reflux
… with the separation of close boiling mixtures is extractive distillation. The selective action of a solvent, which is relatively non-volatile compared to the components of a mixture to be separated, is utilized. The solvent and extract are then separated by distillation, and part of the extract is …

A study of the mannich reaction with certain phenols, of the causes of formation of coloured products and the prevention of their occurence
… and cardol in cashew nut shell liquid by extractive distillation using bases has been devised.

Phase Equilibria and Transport Properties of Gas-Saturated Ionic Liquids
… mixtures that make their separation challenging. Extractive distillation with ionic liquids (ILs) as entrainers has emerged as a promising alternative for effective HFC separation. To evaluate the feasibility and optimize the design of such processes, a comprehensive understanding of the …
