“…The activity of water is also a function of dissolved species thereby impacting observed membrane separation factors 189. Nakano et al investigated the impact of sodium citrate, sodium lactate, ammonium citrate tribasic, glycerin, glucose, and xylose on the vapor–liquid partitioning of several alcohols including ethanol 190. Only glucose and xylose did not impact the VLE behavior of the alcohols.…”

Although several separation technologies are technically capable of removing volatile products from fermentation broths, distillation remains the dominant technology. This is especially true for the recovery of biofuels such as ethanol. In this paper, the status of an emerging membrane-based technology, called pervaporation, for this application is reviewed. Several issues and research priorities which will impact the ability of pervaporation to be competitive for biofuel recovery from fermentation systems are identified and discussed. They include: increased energy efficiency; reduction of capital cost for pervaporation systems; longer term trials with actual fermentation broths; optimized integration of pervaporation with fermentor; synergy of performing both alcohol recovery and solvent dehydration by pervaporation with dephlegmation fractional condensation technology; and updated economic analyses of pervaporation at various biofuel production scales. Pervaporation is currently viable for biofuel recovery in a number of situations, but more widespread application will be possible when progress has been made on these issues.

“…The binary system ethanol-water has been widely studied 3,4 as well as the binary and ternary systems consisting of ethanol, water, and 3-methyl-1butanol. [5][6][7][8] Nevertheless, published data on 2-methyl-1butanol are scarce. 9,10 Accordingly, it is worthwhile to study several equilibrium systems that involve 2-methyl-1-butanol.…”

“…To reach this goal, a knowledge is needed of the phase equilibria for the binary and ternary systems that are formed by the main components (water, ethanol, and isoamyl alcohols).

Vapor-liquid equilibrium data were presented for the ethanol + 2-methyl-1-butanol system, obtained at three operating pressures. A modified Othmer still was used for data acquisition. When the Herington area test was applied to the experimental result, good thermodynamic consistency was found. Several equations based on both classic G E models (Margules and Van Laar) and local composition based models (Wilson, NRTL, and UNIQUAC) were used for data correlation. The UNIFAC group contribution model was applied to predict the activity coefficients of the binary system under study. Results for the ethanol + 2-methyl-1-butanol binary system showed a positive deviation from ideality at all pressures investigated.
