Book Description
This book describes the tremendous progress that has been made in the development of gas separation membranes based both on inorganic and polymeric materials. Materials discussed include polymer inclusion membranes (PIMs), metal organic frameworks (MOFs), carbon based materials, zeolites, as well as other materials, and mixed matrix membranes (MMMs) in which the above novel materials are incorporated. This broad survey of gas membranes covers material, theory, modeling, preparation, characterization (for example, by AFM, IR, XRD, ESR, Positron annihilation spectroscopy), tailoring of membranes, membrane module and system design, and applications. The book is concluded with some perspectives about the future direction of the field.

Book Description
Membranes and membrane separation techniques have grown from a simple laboratory tool to an industrial process with considerable technical and commercial impact. The book deals with both the fundamental concepts of preparation, characterization and modification, practical applications along with recent advancements of electro-spun and phase inverted polymeric membranes. Divided into two parts, part one of this book covers the fundamental concepts and practical applications of novel electro-spun membranes while the latter covers basic concepts and further advancements of the conventional phase inverted membranes extensively. Key Features Covers fundamental concepts and practical applications of electro-spun and phase inverted polymeric membranes Includes general properties, characterization, preparation and modification of polymeric membranes Discusses advanced modification of polymeric membranes (functionalization, grafting) using phase inversion process, and effects of solubility parameter and additives on the phase inversion process Reviews electro-spun membranes for biomedical applications, industrial effluents treatment and removal of water contaminants Explores a separate economic analysis section for the discussed membranes

Book Description
The development of polymeric membranes for gas separations has provided an alternative to traditional energy-intensive processes, especially for hydrocarbon separations. Material studies of the membrane can provide insights to its formation and modification. Gas permeation behaviour through two types of polymeric membrane material is investigated herein. Though the main objective of our investigation was to determine the hydrocarbon gas permeation properties of poly(ether-b-amide) PEBAX® 2533 copolymer membranes over a range of operating temperatures and pressures, we first tested a poly(ethylene oxide) (PEO) membrane for permeability of ethane and ethylene. The screening results from the tests of PEO membranes containing silver salts, indicate that although PEO membranes may possess high olefin/paraffin selectivity through facilitated transport, difficult membrane preparation and unstable structure remain major obstacles to their commercial use. However, the knowledge acquired on preparation technique and permeability testing from these trials was carried over to our study of PEBAX® 2533 membranes. Permeability coefficients were determined at temperatures ranging from 25C̊ to 75C̊, and pressures from 25 psig to 200 psig for ethane, ethylene, nitrogen, propane, propylene, and carbon dioxide. The PEBAX® 2533 membranes showed high organic gas permeabilities. Plasticization effects on the membrane were pronounced with propane and propylene at elevated pressure (100 psig). Activation energies of permeation (Ep) were determined. Ep of nitrogen is nearly constant and is the highest among gases tested in the pressure range. Ep shows a linear decreasing trend as pressure increases for hydrocarbons. Relatively high selectivities (12 to 26) were observed for the polar and non-polar gas pair CO2/N2. As temperature increased, the selectivity of CO2/N2 decreased. This study provides the groundwork for the use of PEO and PEBAX® 2533 membranes for hydrocarbon separations.
