“…Further complicating this matter, in order to Another membrane process, membrane distillation, is oft en mentioned alongside pervaporation for the recovery of orga nic compounds, such as alcohols from water. 3,122,135,189,[202][203][204][205][206][207][208][209][210] In membrane distillation, however, a porous membrane rather than a nonporous membrane separates the feed liquid from the gas or vacuum purge applied on the permeate side of the membrane. In the case of a vacuum purge, the process is commonly referred to as vacuum membrane distillation.…”

Multi-column distillation followed by molecular sieve adsorption is currently the standard method for producing fuel-grade ethanol from dilute fermentation broths in modern corn-to-ethanol facilities. As the liquid biofuels industry transitions to lignocellulosic feedstocks, expands the end-product portfolio to include other alcohols, and encounters more dilute alcohol concentrations, alternative separation technologies which are more energy effi cient than the conventional approach will be in demand. In this review, alcohol recovery technology options and alcohol dehydration technology options for the production of ethanol and 1-butanol are reviewed and compared, with an emphasis on the energy footprint of each approach. Select hybrid technologies are also described.

“…(1), and the temperature as well as the concentration at the membrane surface approach the bulk ones [1]. This means a reduction of the boundary layer thickness when Reynolds number increases resulting in an increase of the driving force and higher AGMD permeate flux [39][40][41][42][43]. Within the laminar region (Re b 2300), the AGMD permeate flux is expected to increase by increasing the feed flow rate prior to reaching an asymptotic value [1].…”
