Multi-lab study on the pure-gas permeation of commercial polysulfone (PSf) membranes: Measurement standards and best practices

Characterization of Commercial Ceramic and Hybrid Membranes Using Gas Permeation and Permporometry Tests

The gas separation performance of commercial ceramic Titania and hybrid silica (HybSi®) membranes was assessed using the gas permeation and permporometry methods. Results indicated that the HybSi® membranes have a hybrid surface containing regions covered by a polymeric matrix and others with inorganic pores. These membranes have high H2 selectivity, which incre...

Fabrication and Evaluation of Functionalized Nano-titanium Dioxide (F-NanoTiO2)/ polysulfone (PSf) Nanocomposite Membranes for Gas Separation

Effects of Polysulfone (PSf) Support Layer on the Performance of Thin-Film Composite (TFC) Membranes

The performance of thin-film composite (TFC) membranes was related to the properties of support layers. In this study, polysulfone (PSf) membranes formed by the phase inversion process under various concentrations of PSf and polyvinylpyrrolidone (PVP) additive were used as support layers to prepare polyamide (PA) TFC membranes by the interfacial polymerization (IP). The effects of PSf and PVP c...

Study on Commercial Membranes and Sweeping Gas Membrane Distillation for Concentrating of Glucose Syrup

In this work, sweeping gas membrane distillation (SGMD) process was used for concentrating of glucose syrup. The main questions in this work include: is SGMD process practical for concentrating of glucose solution prior the fermentation step in bioethanol process?. and are the commercially available hydrophobic membranes sufficient enough to develop the SGMD process in pilot scale for this issu...

Polyester/SiO2 Nanocomposites: Gas Permeation, Mechanical, Thermal and Morphological Study of Membranes

Using of nanocomposite membranes composed of polymer and inorganic nanoparticles is a novel method to enhance gas separation performance. In this study, membranes were fabricated from polyester (PE) containing silica (SiO2) nanoparticles and gas permeation properties of the resulting membranes were investigated. Morphology of the membranes, SiO2 distribution a...
