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...
متن کاملComparison of the Separation Characteristics of Polyvinyl Alcohol Membrane in Dehydration of Benzene and Toluene Using Pervaporation
Pervaporation (PV) is a well-established membrane technique used in separation; especially dehydration of organic solvents. Along with other parameters such as permeate pressure and feed temperature; feed composition is an important parameter, which affects separation characteristics and membrane performance in pervaporation. In this paper, the separation characteristics of a hydrophilic polyvi...

متن کاملPreparation and Characterization of Poly (vinyl alcohol) Membrane for Pervaporation Separation of Water-Organic Mixtures
Poly (vinyl alcohol) membranes were prepared by in-situ crosslinking of poly (vinyl alcohol) with glutaraldehyde as a crosslinking agent and hydrochloric acid as catalyst and the membranes were used to separate mixtures of IPA and water. Effects of feed composition, operating temperature, vacuum pressure and Reynolds number on permeation performance of the membranes were evaluated. The results ...
متن کاملFabrication of Polyvinyl Alcohol/Kefiran Nanofibers Membrane Using Electrospinning
The Poly (vinyl alcohol)/Kefirane nanofiber membrane was successfully fabricated for the firsttime using electrospinning of the polyvinyl alcohol (PVA) and Kefirane blend solution. Scanningelectron microscope (SEM), attenuated total reflectance Fourier transform infrared (ATRFT-IR), and differential scanning calorimetry (DSC) were used to characterize the electrospunPoly (vinyl alcohol)/Kefiran...
