Application of poly(ethylene terephthalate)-graft-polystyrene membranes in pervaporation

, 2006
Gamma radiation-induced grafting of styrene (ST) onto poly(ethylene terephthalate) (PET) films was used to prepare poly(ethylene terephtalate)/polystyrene (PET-g-PST) membranes having various degrees of grafting.

Synthesis and pervaporation performance of high-reproducibility silicalite-1 membranes

, 2008
High-reproducibility silicalite-1 membranes were synthesized on silica tubes by in-situ hydrothermal synthesis, and the relative standard deviation (R.S.D.) of average separation factor for eight membranes was only 7.5%.

Pervaporation of ethanol from lignocellulosic fermentation broth

, 2013
Pervaporation can be applied in ethanol production from lignocellulosic biomass. Hydrophobic pervaporation, using a commercial PDMS membrane, was employed to concentrate the ethanol produced by fermentation of lignocellulosic hydrolysate.

PERVAPORATION OF ETHANOL AND ACETONE ABOVE NORMAL BOILING TEMPERATURES

, 2015
Pervaporation experiments were performed at higher than normal feed liquid boiling temperatures by applying pressure to the feed compartment. Ethanol, acetone, and aqueous ethanol solutions were pervaporated through silicone rubber dense membranes. Large

A comparative study on removal of boron via pervaporation and vacuum membrane distillation using zirconium metal–organic framework-loaded poly(lactic acid) membrane

Applied Water Science
Boron mineral is very important for the life. However, exceeding the standards of boron minerals, especially in water to be used as domestic water, causes health and environmental problems. The commercial method used to separate boron minerals from water

Pervaporation of ethanol-water solutions using commercially available pervaporation membranes

Thesis (MEng)--Stellenbosch University, 2024.ENGLISH ABSTRACT: Pervaporation can be used for the recovery of bioethanol from fermentation broths. Most previous studies focused on laboratory-synthesized membranes and the OFAT approach has generally been ...

Dehydration of solvents by pervaporation

, 2018
V zaključnem delu smo obravnavali proces pervaporacije. Iz topil, ki se uporabljajo v farmaciji, je potrebno odstraniti vodo v čim večji meri, da topila lahko ponovno uporabimo. Obravnavali smo dehidracijo topil s pomočjo pervaporacije. Posebno pozornost
