Membrane Gas Separation

Gas separation membranes offer a number of benefits over other separation technologies, and they play an increasingly important role in reducing the environmental impacts and costs of many industrial processes. This book describes recent and emerging results in membrane gas separation, including highlights of nanoscience and technology, novel polymeric and inorganic membrane materials, new membrane approaches to solve environmental problems e.g. greenhouse gases, aspects of membrane engineering, and recent achievements in industrial gas separation. It includes: Hyperbranched polyimides, amorphous glassy polymers and perfluorinated copolymers Nanocomposite (mixed matrix) membranes Polymeric magnetic membranes Sequestration of CO2 to reduce global warming Industrial applications of gas separation Developed from sessions of the most recent International Congress on Membranes and Membrane Processes, Membrane Gas Separation gives a snapshot of the current situation, and presents both fundamental results and applied achievements.

Membrane Separation Processes: Theories, Problems, and Solutions provides graduate and senior undergraduate students and membrane researchers in academia and industry with the fundamental knowledge on the topic by explaining the underlying theory that is indispensable for solving problems that occur in membrane separation processes. All major membrane processes are discussed, and an economic analysis is provided. Separation processes such as RO, UF, MF, RO, PRO and MD are thoroughly discussed. During the last two decades, the scope of the R&D of membrane separation processes has been significantly broadened. Other sections in the book cover membrane contactor and membrane adsorption. In addition, hybrid systems in which two or more membrane systems are combined are now being investigated for large-scale applications. Written by renowned experts with extensive experience with industry, education and R&D who have complementary expertise In-depth coverage of the most important conventional and emerging membrane processes Provides fundamental membrane theories for solving problems in separation processes without using complicated software

This two-volume set presents the state of the art, and potential for future developments, in membrane engineering for the separation of gases.

The development of a new class of nanocomposite membranes has served as one of the most prominent strategies to address the intrinsic limitations of conventionally used polymeric and inorganic membranes. Nanocomposite membranes consist of nanosized inorganic nanomaterials that are incorporated into the structure of continuous polymer matrices. Owing to the exceptional properties exhibited by the nanomaterials, the resultant nanocomposite membranes demonstrate higher selectivity and permeability that surpass the Robeson upper boundary limit. Nanocomposite Membranes for Gas Separation provides a comprehensive review of the advances made in the development and application of gas separation nanocomposite membranes. In particular, the book covers the focuses on the fabrication, modification, characterization and applications of nanocomposite membranes for gas separation. It is an important reference source both for materials scientists, environmental engineers and chemical engineers who are looking to understand how nanocomposite membranes are being used to create better techniques for gas separation. Provides detailed insights in the fabrication, modification, characterization and applications of nanocomposite membranes for gas separation Shows how nanotechnology is being used to address current limitations of the development of polymeric and inorganic membranes for gas separation, including low separation performance in terms of permeability and selectivity Explores the potential of nanocomposite membranes to help create more effective gas separation techniques

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.

Elaborating on recent and future developments in the field of membrane engineering, Volume 1 focuses on new membrane materials which have recently emerged in gas separation. Covering graphene/graphene oxide based membranes, PIMs, thermally rearranged membranes, and new mixed matrix membranes, alongside membrane pilot plant trials of gas separation, such as CO2 from flue gas and biogas, as well as a cost analysis of competitive membrane and hybrid systems, this book provides a comprehensive account. Together with Volume 2, these books form an innovative reference work on membrane engineering and technology in the field of gas separation and gaseous phase membrane reactors.

Supplemented with over 200 helpful illustrations, this book offers an exposition of the chemical natures of hypothetical black box membranes and those of specific polymers. Chemical structure at the functional group level is considered as the synthesis of steric and polar factors.

This book aims at illustrating several examples of different membrane compositions ranging from inorganic, polymeric, metallic, metal organic framework, and composite which have been successfully deployed to separate industrially relevant gas mixtures including hydrogen, nitrogen, methane, carbon dioxide, olefins/parafins among others. Each book chapter highlights some of the current and key fundamental and technological challenges for these membranes that must be overcome in order to envision its application at industrial level.
