PDMS/PVDF composite pervaporation membrane for the separation of dimethyl carbonate from a methanol solution

In this paper, polydimethylsiloxane (PDMS) composite membranes that were supported using polyvinylidene fluoride (PVDF) microfiltration membrane were developed for the pervaporation (PV) of dimethyl carbonate (DMC) from a methanol solution. Experimental studies on the solubility and the diffusivity of pure DMC and methanol in the membrane were first measured. Higher DMC uptake indicates that th...

CFD simulation of pervaporation of organic aqueous mixture through silicalite nano-pore zeolite membrane

Nanopore silicalite type membranes were prepared on the outer surface of a porous-mullite tube by in situ liquid phase hydrothermal synthesis. The hydrothermal crystallization was carried out under an autogenously pressure, at a static condition and temperature of 180 °C with tetrapropylammonium bromide (TPABr) as a template agent. The molar composition of the starting gel of silicalite zeolite...

Pervaporation: Membrane Separations

G-100 is used for higher molecular mass proteins. The solutions of proteins are prepared in guanidine hydrochloride (10 mg mL ), and cytochromec (10 mg mL ) is used as an internal standard. Descending chromatography is carried out at room temperature under an inclination angle of 253 to the horizontal. After 3 h of development the quotient Rs protein/Rs cytochrome c is calculated for each prote...

Acetic acid Separation as a Function of Temperature Using Commercial Pervaporation Membrane

Acetic acid was separated from a dilute mixture using a commercial polyvinyl alcohol (PVA) membrane.  Intrinsic separation characteristics of the membrane were studied as a function of temperature.  The degree of membrane swelling decreased marginally with increase in feed temperature. At 25oC the maximum degree of swelling was found out to be 46.3%, which reduced to 39.5%...

EFFECT OF OPERATING CONDITIONS ON THE DEHYDRATION OF TOLUENE BY PERVAPORATION USING A POLYVINYL ALCOHOL MEMBRANE

The effects of operating parameters such as feed temperature and permeate-side pressure on the performance of a commercial PVA membrane in the dehydration of toluene by a pervaporation (PV) membrane system is studied in the present work. The results obtained indicate that increasing temperature in the range of 40 to 70 °C and reducing permeate pressure in the range of 1 to 10 mmHg increase memb...
