Experimentelle und theoretische Untersuchungen zur Erweiterung der Gruppenbeitragsmethoden UNIFAC und Modified UNIFAC (Dortmund)
… mit der visuellen Methode, azeotrope Punkte an einer Drehbandkolonne, Grenzaktivitätskoeffizienten mit der Gas-Flüssig-Chromatographie und Dampf-Flüssig-Gleichgewichte mit einer neu aufgebauten, computergesteuerten Apparatur nach dem dynamischen Prinzip gemessen. Diese …

Feasibility Analysis of Estrification Systems with Entrainers
… of liquid-liquid split of the lowest boiling azeotrope between the entrainer and water, which is one of the desired products in esterification production systems. Dichloromethane and trichloromethane are the entrainers that are very toxic, yet still conventionally used for production of those …

Thermal diffusion near a binary liquid azetrope
… behavior. It appears to increase rapidly as the azeotrope temperature is approached. In addition to the thermal diffusion factor, the heat of transport and thermal diffusion coefficient were determined for the ethanol-water system as functions of temperature, based on the assumption of Onsager …

A Study of Thiol Based Bound Antioxidants in Acrylonitrile-Butadiene Rubbers
… before and after extraction with an organic azeotrope. For comparison the effectiveness of commercially available copolymerised antioxidant, N-(4-anilinophenyl) methacrylamide and a high molecular weight partially polymerised antioxidant, 2,2,4-trimethy1-1, 2-dihydroquinoline, were also …

Separation of solvents from selected biopolymeric matrixes and aqueous mixtures by ultrasound
… is used to overcome the azeotropic bottleneck in azeotrope-forming systems (e.g., ethanol + water). While a few conventional distillation technologies and new separation approaches have been developed for azeotropes, they rely largely on separation via phase equilibrium, or involve large capital, …

Polyol induced extraction (PIE) of water from organic solvents
… thus capable of breaking the ACN-water azeotrope. We also show that polyols as separating agents are equivalent or better than MSAs such as sugars and salts. Further, liquid polyols such as glycerol are far easier to remove, and are better suited to commercial processes.</p> …

Comparison of Multieffect Distillation and Extractive Distillation Systems for Corn-Based Ethanol Plants
Recent publications on ethanol production and purification shows optimized energy and water consumptions as low as 22,000 Btu/gal ethanol and 1.54 gal water/gal ethanol respectively using multieffect distillation. Karuppiah, et al use column rating and mathematical optimization methods and shortcut …
