This book was released on 2015-07-22 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Membrane technology has a promising future in the refining, petrochemical, and natural gas industries. One area of importance is the separation of CH4 and CO2. Gas separation membranes of high CO2 permeability and selectivity have great potential in both natural gas sweetening and carbon dioxide capture. Polymer of intrinsic microporosity (PIM) has got many promising results in this regard. Many modified PIM membranes results permselectivity above Robinson upper bound. The big problem that should be solved for these polymers to be commercialized is their aging through time. Modeling of pure and mixed gas sorption of carbon dioxide and methane which is carried out using dual mode sorption model and Non-equilibrium lattice fluid model shows the best fit with experimental results.

Download or read book Membrane Engineering for the Treatment of Gases written by Enrico Drioli and published by Royal Society of Chemistry. This book was released on 2011-07-06 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Membranes already have important applications in artificial organs, the processing of biotechnological products, food manufacture, waste water treatment, and seawater desalination. Their uses in gaseous mixture separations are, however, far from achieving their full potential. Separation of air components, natural gas dehumidification and sweeting, separation and recovery of CO2 from biogas, and H2 from refinery gases are all examples of current industrial applications. The use of membranes for reducing the greenhouse effect and improving energy efficiency has also been suggested. New process intensification strategies in the petrochemical industry have opened up another growth area for gas separation membrane systems and membrane reactors. This two volume set presents the state-of-the-art in membrane engineering for the separation of gases. It addresses future developments in carbon capture and utilization, H2 production and purification, and O2/N2 separation. Topics covered include the: applications of membrane gas separation in the petrochemical industry; implementation of membrane processes for post-combustion capture; commercial applications of membranes in gas separations; simulation of membrane systems for CO2 capture; design and development of membrane reactors for industrial applications; Pd-based membranes in hydrogen production; modelling and simulation of membrane reactors for hydrogen production and purification; novel hybrid membrane/pressure swing adsorption process for gas separation; molecular dynamics as a new tool for membrane design, and physical aging of membranes for gas separations. Volume 2 looks at problems combined with membrane reactors.

Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the fundamentals of CO2 storage for long-term sequestration in a subsurface geologic formation. In general, membrane gas separation can find a large room of application in flue gas. To achieve the development of this technology on a larger scale than which is possible in the lab we have to use membrane engineering. Consequently, greater emphasis is placed on novel materials for gas separation. Possible design strategies and role of novel materials are discussed. Additionally, the latest progress in design and preparation of asymmetric membranes for natural gas purification are highlighted. In fact, further development should focus on module and process design in order to bring gas separation membrane technology into commercial application. Therefore, the keys issues to propel current research towards industrial application are examined. Besides, the feasibility of implementing polyimide membrane for CO2 removal under real industrial conditions and its economic viability are highlighted. In order to exhibit excellent film-forming properties, zeolite membrane and cellulose acetate butyrate membrane areaddressed. Interestingly, it was found that the most accurate theoretical three-phase model is arguably revised Pal model with average percentage error of 0.74%.
Download or read book Effect of Different Type of Polymer Concentration on Asymmetri Polysulfone Membrane for CO2 CH4 Separation written by Nur Amira Abdullah and published by . This book was released on 2010 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study is to developed polysulfone (PSU) asymmetric membrane for gas separation and to identify the concentration of polysulfone in dope solution to produce high selectivity membrane for CO2/CH4 gas separation. Polysulfone was selected as the polymer material in this research since it is glassy type polymer that exhibit good mechanical properties compare to others while 1-Methyl-2-Pyrrolidone (NMP) is chosen as the solvent because it is low toxicity and completely miscible with water, organic acid and alcohol. Polysulfone asymmetric membrane was prepared by mixing a dope, where polysulfone polymer was mixed with 1-Methyl-2Pyrrolidone (NMP). Three sample of solution was prepared with different type of concentration of polysulfone polymer which is 20 wt%, 25 wt% and 30 wt% respectively. Before perform gas permeation test, polysulfone membrane was coating with PDMS and n-hexane with the composition 3 wt% and 97 wt% respectively. Permeation test was carried out by using single gas permeation test by testing gas carbon dioxide (CO2) and methane (CH4). The membranes were characterized by using Scanning Electron Microscope (SEM) and Fourier Transform Infrared Spectroscopy (FTIR). Through SEM analysis, the morphology and structure of the membrane at 20 wt% concentration of polysulfone shows structural pores using 1000 magnification. Membranes with 30 wt% of PSU exhibits the most selective membrane with selectivity about 2.619 while membrane with 20 wt% shows the lowest selectivity that is 1.22. This is because the increasing polysulfone polymer concentration resulted a denser and thicker skin layer of membrane so that the membrane with high polysulfone concentration become more selective but less permeability to the gas separation.

This book was released on 2022-01-22 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing need for better membranes in several emerging application fields especially those related to energy conversion and storage as well as to water treatment and recycling. Processability, is an important functional property, often ignored, especially in the early discovery phase for new materials, but it should be one of the most important properties, that needs to be considered in the development of better membrane materials. Useful membrane materials have to be capable of being formed into thin membranes, in particular for membrane gas separation, water treatment and desalination, and then packaged, into large area membrane modules. All gas separation membranes that are in current commercial use are based on polymers, which are solution-processable. This book intends to deal with composite, in most cases hybrid polymer-based membranes for three separate application fields: energy conversion, energy storage and water treatment and recovery. Each chapter will explain clearly the various membrane processes then go on to discuss in detail the corresponding advanced membranes used. The logic that lies behind this is that you have to understand the process in order to develop new high-performance membranes. By taking this approach, the author aims to overcome the disconnection that currently exists between membrane materials scientists and industrial process engineers. - Discusses interdisciplinary content by a single author, approaching synthesis and development of materials from the perspective of their processability - Describes the novel aspects of membrane science that is related to energy storage, conversion and wastewater treatment - Presents an emphasis on scientific results which have an impact on real applications in terms of renewable and clean energy challenges
