Design Calculations and Parametric Analysis of a Membrane Permeator for Hydrogen-Helium Separation
Abstract: Palladium or palladium alloy-based membrane permeators have been proposed to be used for the separation of hydrogen isotopes from helium in fusion energy plants on account of the very high selectivity for hydrogen exhibited by these membranes. In this work, the preliminary design and parametric analysis of a single stage membrane permeator having different flow patterns have been carried out and the effect of various parameters on the membrane area …

To explore the effect of polyethylene glycol additive on mechanical and gas permeation properties of polyvinyl alcohol membranes
Abstract: Polyvinyl alcohol (PVA) membranes were prepared by solution casting and blended with Polyethylene glycol (PEG) in de-ionized water which led to the formation of porous and flexible membranes. Extensive experimentation were performed, in order to find out that at what composition of PEG pores will be generated in the PVA membranes. The PVA polymer is a hard and crystalline thermoplastic so high concentrations of PEG were used, i.e. 40 wt%, …

Flow Reversal and Pressure pulsation: Innovative technique to enhance flux in Nanofiltration
Abstract: Reduction in Permeate flux with the period of time is the major drawback for the Pressure-driven membrane processes. Concentration polarization and membrane fouling are the two major limitations for the Pressure-driven membrane filtration processes. They lead to the severe flux decline and that need to be controlled for the better process efficiency. The resistance determination provides basis for selection of membrane and appropriate pressure –driven separation process. This paper outlines …
