Book Description :

The application of the microporous hollow fiber membrane contactor for gas absorption and stripping has gained considerable attention recently and is still a relatively new concept. In comparison with most membrane separation processes which use a dense selective layer on one side of the fibers, the microporous membrane used in the membrane contactor is not selective. Instead of the selective layer, a liquid flow is introduced in one side of the fiber that can absorb gas components physically or chemically. This leads to a higher mass transfer rate due to lower membrane resistance. Additionally, because there is no selective layer, a very small pressure drop across the membrane is required for mass exchange. Compared to the traditional columns membrane contactor has several advantages. Although the membrane wall introduces an additional resistance that does not exist in conventional towers, a higher specific surface area in these type of modules offers much higher mass transfer rates. These advantages have led to a number of investigations on the use of membrane contactors for gas absorption and stripping. Here we have studied its application for removing pollution from industrial

Book Description :

Olefin/paraffin separation is a large potential market for membrane applications. Carbon molecular sieve membranes (CMS) are promising for this application due to the intrinsically high separation performance and the viability for practical scale-up. Intrinsically high separation performance of CMS membranes for olefin/paraffin separations was demonstrated. The translation of intrinsic CMS transport properties into the hollow fiber configuration is considered in detail. Substructure collapse of asymmetric hollow fibers was found during Matrimid® CMS hollow fiber formation. To overcome the permeance loss due to the increased separation layer thickness, 6FDA-DAM and 6FDA/BPDA-DAM polyimides with higher rigidity were employed as alternative precursors, and significant improvement has been achieved. Besides the macroscopic morphology control of asymmetric hollow fibers, the micro-structure was tuned by optimizing pyrolysis temperature protocol and pyrolysis atmosphere. In addition, unexpected physical aging was observed in CMS membranes, which is analogous to the aging phenomenon in glassy polymers. For performance evaluation, multiple "proof-of-concept" tests validated the viability of CMS membranes under realistic conditions. The scope of this work was expanded from binary ethylene/ethane and propylene/propane separations for the debottlenecking purpose to mixed carbon number hydrocarbon processing. CMS membranes were found to be olefins-selective over corresponding paraffins; moreover, CMS membranes are able to effectively fractionate the complex cracked gas stream in a preferable way. Reconfiguration of the hydrocarbon processing in ethylene plants is possible based on the unique CMS membranes.

Book Description :

Water scarcity is nowadays a worldwide problem that requires new water resources and more efficient separation treatment techniques. Membrane distillation (MD) is a non-isothermal process whose driving force is the transmembrane vapor pressure. In this process, non-volatile solutes can be removed from a wide variety of feed aqueous solutions due to the transport of vapor molecules through microporous and hydrophobic membranes. Owing to its various advantages, water desalination by MD is an environmentally-friendly alternative, which can tackle the water shortage issue. The main challenge of MD is the design and preparation of improved membranes with suitable characteristics for this process. Hollow fiber is currently the most attractive membrane geometry for MD industrial implementation. Consequently, membrane engineers are endeavoring to develop novel hollow fiber membranes that meet the demanding MD requirements. In this PhD Thesis, advanced hollow fiber membranes have been prepared by the dry/wet or wet/wet spinning technique for desalination by MD. A comprehensive analysis of different spinning parameters effects on the membrane formation mechanism, characteristics and MD performance has been carried out. The highly hydrophobic copolymer, poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), has been chosen for the preparation of the organic hollow fiber membranes. Prior membrane preparation, the type of solvent and the mixed solvent used to prepare the PVDF-HFP dope solution have been studied taking into account the characteristics of the dope solution, which dictates the coagulation kinetic and the thermodynamic precipitation of the membrane formation. The adequate mixed solvent was found when the dope solution became thermodynamically more stable and the coagulation rate of the membrane phase inversion was slower due to the increase of the viscosity of the dope solution. The hollow fiber membrane prepared under these conditions exhibited macro-void free and thick sponge-like structure, resulting in suitable characteristics for MD and high direct contact membrane distillation (DCMD) permeate flux...

Book Description :

This thesis describes research into the utilization of conducting polymer polyaniline (PAni) as a material for the development of asymmetric hollow fiber membranes for gas separations. In order to ensure the consistency of the emeraldine base PAni molecular weight and the quality and purity throughout this research, the fresh batch polymer was synthesized in-house prior to each hollow fiber spinning. The initial gas permeation test revealed that the hollow fiber fabricated with high molecular weight PAni was favourable due to the highly viscous solution prepared with significant polymer chain entanglement that contributed to the formation of a more desirable membrane structure. However, the major turn around of the work was the introduction of volatile tetrahydrofuran (THF) to less volatile N-methyl-2-pyrrolidone (NMP) in the dope solution that promoted a proper formation of integrally skinned membranes. The effective removal of THF at a high spinning air gap further improved the fabricated membrane morphology which consisted of a denser effective skin layer, transition layer and finely porous substructure with smaller macrovoids. In addition, the spine line stress-induced orientation at a high air gap was responsible for further stretching the nascent fiber creating more packed structure that assisted toward improving the gas separation performance of the membranes. The induced molecular orientation also resulted in improvement in mechanical properties of the hollow fibers. Polyaniline derivative was synthesized to overcome the PAni solubility issue and to suppress the formation of PAni micro-agglomerates in the highly viscous dope solution. Integrallyskinned hollow fiber membranes were successfully prepared by dry-jet wet spinning from poly(ortho-anisidine) (POAn) dissolved in NMP and THF system. The bulky methoxy group introduced to the polymer backbone increased both the polymer chain rigidity and specific free volume of POAn as compared to PAni, producing membranes with significantly enhanced gas pair separation factors and small gases (hydrogen and carbon dioxide) permeation rates. The final focus of this study was investigating the potential effect of the aging process on PAni and its derivative membranes gas separation and mechanical properties. Poly(o-anisidine) membrane properties were found to be more stable than polyaniline membranes throughout the aging period, providing a strong foundation for further investigation of poly(o-anisidine) as a membrane material for gas separation towards commercial application.
