Gas Permeation Modeling through a Multilayer Hollow Fiber Composite Membrane

In this study, a time-dependent 2D axisymmetric model of a multilayer hollow fiber composite membrane for gas separation is proposed. In spite of the common multilayer membranes, which a dense layer coated on a porous support layer and subjected into the feed stream, here, the porous support is exposed to the feed gas. In this regard, the governing equations of species transport are developed f...

Surface modification of nanostructured ceramic membranes for direct contact membrane distillation

The objective of this research was to evaluate a select number of promising surface treatments for making ceramic membranes hydrophobic and suitable for application in direct contact membrane distillation (DCMD). Alumina anodiscTM membranes were made hydrophobic through surface treatments that utilized perfluorodecyltriethoxysilane, trimethylchlorosilane, or trichloromethylsilane. The effective...

Boron removal from aqueous solution by direct contact membrane distillation.

The removal of boron from aqueous solution by direct contact membrane distillation (DCMD) was studied with self-prepared polyvinylidene fluoride (PVDF) hollow fiber membranes in the present work. The effect of pH, boron concentration, temperature and salt concentration of the feed solution on the boron rejection was investigated. The experimental results indicated that boron rejection was less ...

Effect of Ethylene Glycol as Pore Former on Polyphenylsulfone Hollow Fiber Membrane for Crude Palm Oil Deacidification through Membrane Contactor

In this study, polyphenylsulfone (PPSU) hollow fiber membrane was fabricated via a wet spinning method with the addition of ethylene glycol (EG) in the range of 0-10 wt% as the additive. The EG was added to improve the membrane pore formation and interconnectivity for better membrane contactor performance in extracting and removing the free fatty acid (FFA) from crude palm oil (CPO). Four diffe...

Fabrication and Characterization of Polyetherimide Hollow Fiber Membrane Contactor for Carbon Dioxide Stripping from Monoethanolamine Solution

In this research, process asymmetric polyetherimide hollow fiber membranes using ethanol (0, 2 and 4 wt%) as non-solvent additive in the polymer dope via phase inversion method were fabricated. Aqueous solution of 1-methyl-2-pyrrolidine (NMP) (90%) was applied as a bore fluid to avoid inner skin layer formation and water was used as the external coagulant. The morphology of fabricated membranes...
