Nafion/PEG hybrid membrane for CO2 separation: Effect of PEG on membrane micro-structure and performance

Pebax-Modified Cellulose Acetate Membrane for CO2/N2 Separation

Carbon dioxide (CO2) release from the exhaust gas streams of power plants that burn fossil fuels contributes the most emission of this gas, which includes more than half of the greenhouse effects. Thus, the separation of CO2 from exhaust gases is one of the main environmental concerns. Membrane technology, due to many advantages, has attracted many research attentions among the various gas sepa...

The Coating Effect of PANI/Silver on Performance of Polysulfone Membrane Toward Protein Separation

The effects of different coating time of PANI/Silver onto polysulfone (PSf) membrane surface were investigated based on the morphology, contact angle, surface roughness and rejection towards BSA, pepsin and trypsin. The membrane was prepared by employing the pressure deposition method toward phase inversed membrane. Thus, PANI particles were forced to adhere on membrane surface by pressure driv...

Effect of Different Additives on Separation Performance of Flat Sheet PVDF Membrane Contactor

This paper investigates effects of different additives on morphology and subsequently, separation performance of asymmetric flat sheet Polyvinylidene fluoride (PVDF) membranes to separate CO2 using membrane contractor. Five different additives from different chemical families including Lithium chloride (salt), Polyethylene glycol 400 (polymer), glycerol (weak anti-solvents), methanol...

Effect of Polymer Concentr ation on the Structure and Performance of Polysulf one Flat Membrane for CO 2 Absorption in Membrane Contactor

Fabrication of (Acrylonitrile Butadiene Styrene/Poly Ethylene Glycol) Nanofiltration Membrane: the Effect of PEG Concentration and Operating Conditions on Membrane Performance

In the current research, ABS-co-PEG nanofiltration membrane was prepared by solution casting technique using N, N dimethyl acetamide as solvent. The effect of PEG concentration as additive in the casting solution on membrane flux, salt rejection, phase inversion time, water content, membrane porosity, membrane tensile strength and fouling was studied. Also the eff...
