Recovery of 2,3-Butanediol by Vacuum Membrane Distillation∗
Separation Science and Technology, 1994Abstract A vacuum membrane distillation process using a microporous polytetrafluoroethylene (PTFE) membrane was developed to concentrate 2,3-butanediol from model 2,3-butanediol solutions and fermentation broths. A 0.22-μm PTFE membrane passed water vapor while retaining 2,3-butanediol. Water flux through the membrane was 4 kg/m2·h at 35°C and 12–14 kg/

Journal of Membrane Science, 2014
Abstract The polytetrafluoroethylene nanofiber membranes for membrane distillation were prepared by sintering the precursor electrospun polytetrafluoroethylene/polyvinyl alcohol composite membranes. The effects of sintering temperature and time on the morphology and properties of the prepared membranes were investigated.

Vacuum membrane distillation for the treatment of coffee products
Separation and Purification Technology, 2019 Vacuum Membrane Distillation (VMD) was applied in two production lines of the coffee industry: the concentration of the coffee extract and the dehydration and recovery of caffeine. Experiments were carried out by using a commercial flat microporous membrane made of polypropylene (0.2 ?m pore size).

Omniphobic Hollow-Fiber Membranes for Vacuum Membrane Distillation
Environmental Science & Technology, 2018Management of produced water from shale gas production is a global challenge. Vacuum membrane distillation (VMD) is considered a promising solution because of its various advantages. However, low-surface-tension species in produced water can easily deposit on the membrane surface and cause severe fouling or wetting problems.

Membrane crystallization (MCr) is emerging as an interesting candidate to extract additional freshwater and raw materials from high-concentrated solutions. Traditionally, MCr has been carried out by using polymeric membranes that have limited chemical and mechanical stability. These shortcomings can be overcome by using ceramic membranes.
