Download or read book Design Preparation and Characterization of Hollow Fiber Membranes for Desalinisation by Membrane Distillation written by Loreto García Fernández and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: Carbon membranes have great advantages of strong mechanical strength and high chemical stabilities, as well as high separation performance to reach the industrial attractive region. Further improvement on membrane performance can potentially offset the relatively high production cost compared to polymeric membranes. However, there are still some challenges related to fabrication of asymmetric carbon membranes, the controlling of structure and pore-size and module up-scaling for commercial application. The aim of this book is to provide the fundamentals on carbon membrane materials for the young researchers and engineers to develop frontier membrane materials for energy efficient separation process. This book describes the status and perspectives of both self-supported and supported carbon membranes from fundamentals to applications. The key steps on the development of high performance carbon membranes including precursor selection, tuning carbon membrane structure and regeneration are discussed. In the end, different potential applications both in gas and liquids separation are well described, and the future directions for carbon membrane development were pointed out. To this end, membrane science and engineering are set to play crucial roles as enabling technologies to provide energy efficient and cost-effective future solutions for energy and environment related processes. Based on this approach the research projects which are trying to find attractive carbon materials in our days are many.

Download or read book Modeling and Experimental Study of Carbon Dioxide Absorption stripping in Gas LLiquid Membrane Contactor written by Nihmiya Abdul Rahim and published by . This book was released on 2015 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural gas consists primarily of methane (CH4) but it also contains considerable amounts of contaminating compounds mainly carbon dioxide (CO2). The presence of CO2 reduces the heating value of the gas and due to its acidic character causes several operational problems. Hence the removal of CO2 from natural gas is crucially important. The focus of this research work is to investigate the potential for the energy efficient and effective separation of CO2/CH4 gas mixture via lean solvent and regenerating of the rich solvent through absorption/stripping mechanism taking place in a hollow fiber gas liquid membrane contactor process (GLMC) which combines the advantages of membrane technology with those of absorbent liquid. In a gas liquid membrane contactor the microporous membrane acts only as an interface between the gas and liquid phases. In this study primarily polyvinylidene fluoride (PVDF) hollow fiber membranes were fabricated via thermally induced phase separation (TIPS) method and the fabricated membranes were characterized using several membrane characterization techniques in order to optimize the membrane fabrication conditions. Then the membrane that had optimal performance was used in GLMC and absorption/stripping experiments were carried out in order to find the optimum operation window that gives higher absorption/stripping performance. Various absorbent liquids like different amino acid salts (AAS) and aqueous ammonia solutions were used as absorbent liquid other than conventional absorption liquids. To improve the stripping performance, enhanced CO2 desorption (based on pH-shift) was studied. Furthermore, a comprehensive mathematical model of GLMC was developed. viii The characterization studies revealed 28% PVDF membrane extruded at high temperature provides the optimum performance and addition of ethanol to the coagulation bath reduces the performance of the membrane. The absorption/stripping studies revealed module configurations and adopted operating parameters have great influence in absorption/stripping performance of GLMC. Further it has been identified AASs are potential absorption liquids in GLMC applications because it have lower potential of membrane wetting due to its high surface tension and good recyclability than the conventional absorption liquid while providing the same absorption performance. The absorption/stripping studies using aqueous ammonia revealed it can be used in GLMC applications. However the two main problems extensive membrane wetting and ammonia slip from the solution have to be overcome successfully. Enhanced CO2 desorption (based on pH-shift) studies revealed by reducing the CO2 rich solution pH the absorption liquid can be regenerated effectively. Finally the developed mathematical model well describes the GLMC process.
