This book was released on 2011-07-06 with total page 319 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 1 focuses predominantly on problems relating to membranes.

Book excerpt: The objective of the present study is to assess the potential usefulness of membrane separation processes for removing CO2 and H2S from low-quality natural gas containing substantial amounts of both these ''acid'' gases, e.g., up to 40 mole-% CO2 and 10 mole-% H2S. The membrane processes must be capable of upgrading the crude natural gas to pipeline specifications ((less-than or equal to) 2 mole-% CO2, (less-than or equal to) 4 ppm H2S). Moreover, these processes must also be economically competitive with the conventional separation techniques, such as gas absorption, utilized for this purpose by the gas industry.

Available in PDF, EPUB and Kindle. Book excerpt: Membrane science and technology is an expanding field and has become a prominent part of many activities within the process industries. It is relatively easy to identify the success stories of membranes such as desali nation and microfiltration and to refer to others as developing areas. This, however, does not do justice to the wide field of separations in which membranes are used. No other 'single' process offers the same potential and versatility as that of membranes. The word separation classically conjures up a model of removing one component or species from a second component, for example a mass transfer process such as distillation. In the field of synthetic membranes, the terminology 'separation' is used in a wider context. A range of separations of the chemical/mass transfer type have developed around the use of membranes including distillation, extraction, absorption, adsorption and stripping, as well as separations of the physical type such as filtration. Synthetic membranes are an integral part of devices for analysis, energy generation and reactors (cells) in the electrochemical industry.

Download or read book Upgrading of Raw Natural Gas Using High-performance Polymer Membranes written by and published by . This book was released on 1993 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The separation of CO2 and H2S from raw natural gas is essential for enhancing the heating value of the gas and for providing environmental safety during nation and use. Membrane separation processes are particularly useful for this application because they are inherently energy-efficient. Membrane processes also offer other important advantages, such as ease of scale-up due to module design, good space and weight efficiency and great flexibility in handling variations in the flow rate, pressure and composition of the raw natural gas streams. In a coordinated effort, the Gas Research Institute and the Department of Energy, Morgantown Energy Technology Center are funding an extensive study at Syracuse University on the relationships between the chemical structure of various polymers and their permeability to different gases. Based on criteria derived from this study, novel fluorine-containing polyimides that exhibit very high C02/CH4, selectivities as well as significant H2S/CH4, selectivities were synthesized. These ''dense'' (homogeneous) membranes separated various mixtures of C02/CH4, and H2S/CH4/CO2 at 35°C (95°F) and at pressures up to 10 atm (147 psi). The results of these measurements agree well with computer simulations. The C02 content of CH4/CO2 mixtures containing as much as 40 mole percent C02 can be reduced with the polyamide membranes to pipeline specifications ((less-than or equal to) 2 mole percent C02). To reduce the H2S content of H2S/CH4/CO2 mixtures to pipeline specifications ((less-than or equal to) 4 ppM H2S), the membranes are best combined with conventional gas-absorption processes, such as a selective amine. Such ''hybrid'' processes for the upgrading of natural gas can be more economical than conventional gas-absorption processes alone.

This book was released on 2013-11-11 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chapters of this book are based upon lectures presented at the NATO Advanced Study Institute on Membrane Processes in Separation and Purification (March 21 - April 2, 1993, Curia, Portugal), organized as a successor and update to a similar Institute that took place 10 years ago (p.M.Bungay, H.K. Lonsdale, M.N. de Pinho (Eds.): Synthetic Membranes: Science, Engineering and Applications, NATO ASI Series, Reidel, Dordrecht, 1986). The decade between the two NATO Institutes witnesses the transition from individually researched membrane processes to an applied and established membrane separation technology, as is reflected by the contents of the corresponding proceeding volumes. By and large, the first volume presents itself as a textbook on membrane processes, still valid, while the present volume focuses on areas of separation need as amenable to membrane processing: Biotechnology and Environmental Technology. Accordingly, the contributions to this volume are grouped into "Membranes in Biotechnology" (11 papers), "Membranes in Environmental Technology" (6 papers), and "New Concepts" (4 papers). This is followed by one contribution each on "Energy Requirements" and "Education", i.e., membrane processes within an academic curriculum. The book thus amounts to a state of the art of applied membrane processing and may well augment the more fundamental approach of its predecessor.

Download or read book Engineering Economical Membrane Materials for Aggressive Sour Gas Separations written by Carine Saha Kuete Achoundong and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal is of this project was to identify principles to guide the development of high performance dense film membranes for natural gas sweetening using hydrogen sulfide and carbon dioxide gas mixtures as models under aggressive sour gas feed conditions. To achieve this goal, three objectives were developed to guide this research. The first objective was to study the performance of cellulose acetate (CA) and an advanced crosslinkable polyimide (PDMC) dense film membrane for H2S separation from natural gas. The second objective was to engineer those polymers to produce membrane materials with superior performance as measured by efficiency, productivity, and plasticization resistance, and the third objective was to determine the separation performance of these engineered membrane materials under more aggressive, realistic natural gas feeds, and to perform a detailed transport analysis of the factors that impact their performance. Work on the first objective showed that in neat CA, penetrant transport is controlled by both the solubility and mobility selectivity, with the former being more dominant, leading to a high overall CO2/CH4 (33) and H2S/CH4 (35) ideal selectivities. However, in uncrosslinked PDMC, H2S/CH4 selectivity favored sorption only, whereas CO2/CH4 selectivity favored both mobility and sorption selectivity, leading to a high CO2/CH4 (37) but low H2S/CH4 (12) ideal selectivities. However, the latter polymer showed more plasticization resistance for CO2. In the second objective, both materials were engineered. A new technique referred to as "GCV-Modification" was introduced in which cellulose acetate was grafted using vinyltrimethoxysilane (VTMS), then hydrolyzed and condensed to form a polymer network. PDMC was also covalently crosslinked to enhance its performance. GCV-Modified CA showed significant performance improvements for H2S and CO2 removal; the permeability of CO2 and H2S were found to be 139 and 165 Barrer, respectively, which represented a 30X and 34X increase compared to the pristine CA polymer. The H2S/CH4 and CO2/CH4 ideal selectivities were found to be 39 and 33, respectively. Crosslinked PDMC showed a higher CO2/CH4 selectivity of 38 with a better plasticization resistance for CO2 and H2S. In the third objective, these materials were tested under aggressive ternary mixtures of H2S/CO2/CH4 with both vacuum and nonvacuum downstream. Even under aggressive feed conditions, GCV-Modified CA showed better performance vs. PDMC, and it remained were fairly stable, making it a potential candidate for aggressive sour gas separations, not only because of its significantly higher productivity, which will help decrease the surface area needed for separation, thereby reducing operating costs, but also because of the lower cost of the raw material GCV-Modified CA compared to PDMC.
