Book Description
Supercritical Fluid Technology for Energy and Environmental Applications covers the fundamental principles involved in the preparation and characterization of supercritical fluids (SCFs) used in the energy production and other environmental applications. Energy production from diversified resources — including renewable materials — using clean processes can be accomplished using technologies like SCFs. This book is focused on critical issues scientists and engineers face in applying SCFs to energy production and environmental protection, the innovative solutions they have found, and the challenges they need to overcome. The book also covers the basics of sub- and supercritical fluids, like the thermodynamics of phase and chemical equilibria, mathematical modeling, and process calculations.A supercritical fluid is any substance at a temperature and pressure above its critical point where distinct liquid and gas phases do not exist. At this state the compound demonstrates unique properties, which can be "fine-tuned," making them suitable as organic solvents in a range of industrial and laboratory processes.This volume enables readers to select the most appropriate medium for a specific situation. It helps instructors prepare course material for graduate and postgraduate courses in the area of chemistry, chemical engineering, and environmental engineering. And it helps professional engineers learn supercritical fluid-based technologies and use them in solving the increasingly challenging environmental issues. - Relates theory, chemical characteristics, and properties of the particular supercritical fluid to its various applications - Covers the fundamentals of supercritical fluids, like thermodynamics of phase and chemical equilibria, mathematical modeling, and process calculations - Includes the most recent applications of supercritical fluids, including energy generation, materials synthesis, and environmental protection

Book Description
Supercritical fluids are neither gas nor liquid, but can be compressed gradually from low to high density and they are therefore interesting and important as tunable solvents and reaction media in the chemical process industry. By adjusting the density the properties of these fluids can be customised and manipulated for a given process - physical or chemical transformation. Separation and processing using supercritical solvents such as CO2 are currently on-line commercially in the food, essential oils and polymer industries. Many agencies and industries are considering the use of supercritical water for waste remediation. Supercritical fluid chromatography represents another, major analytical application. Significant advances have recently been made in materials processing, ranging from particle formation to the creation of porous materials. The chapters in this book provide tutorial accounts of topical areas centred around: (1) phase equilibria, thermodynamics and equations of state; (2) critical behaviour, crossover effects; (3) transport and interfacial properties; (4) molecular modelling, computer simulation; (5) reactions, spectroscopy; (6) phase separation kinetics; (7) extractions; (8) applications to polymers, pharmaceuticals, natural materials and chromatography; (9) process scale-up.

Book Description
Discover the many new and emerging applications of supercritical water as a green solvent Drawing from thousands of original research articles, this book reviews and summarizes what is currently known about the properties and uses of supercritical water. In particular, it focuses on new and emerging applications of supercritical water as a green solvent, including the catalytic conversion of biomass into fuels and the oxidation of hazardous materials. Supercritical Water begins with an introduction that defines supercritical fluids in general. It then defines supercritical water in particular, using the saturation curve to illustrate its relationship to regular water. Following this introduction, the book: Describes the bulk macroscopic properties of supercritical water, using equations of state to explain temperature-pressure-density relationships Examines supercritical water's molecular properties, setting forth the latest experimental data as well as computer simulations that shed new light on structure and dynamics Explores the solubilities of gases, organic substances, salts, and ions in supercritical water in terms of the relevant phase equilibria Sets forth the practical uses of supercritical water at both small scales and full industrial scales Throughout the book, the author uses tables for at-a-glance reviews of key information. Summaries at the end of each chapter reinforce core principles, and references to original research and reviews serve as a gateway and guide to the extensive literature in the field. Supercritical Water is written for students and professionals in physical chemistry, chemistry of water, chemical engineering, and organic chemistry, interested in exploring the applications and properties of supercritical water.

Book Description
For 'better solutions' - this practical guide describes how to take advantage of supercritical fluids in chemical synthesis. Well-established in extractions and materials processing, supercritical fluids are becoming increasingly popular as media for modern chemical syntheses. Historically, the application of compressed gases has been restricted mainly to the production of bulk chemicals. In the last decade, however, research has turned to exploiting the unique properties of supercritical fluids for the synthesis of fine chemicals and specialized materials. Now that the necessary equipment is more readily available, the use of supercritical fluids should become more widespread in both laboratory and industrial scale syntheses. More than merely a concise introduction to the properties of supercritical fluids, here leading experts give a thorough, up-to-date account of chemistry in these alternative media. In-depth scientific commentary, detailed reaction protocols, descriptions of necessary equipment, and an outline of spectroscopic techniques add to the value of this handbook aimed at innovative synthetic chemists.

Book Description
In der Chemie geht es überwiegend um die Frage: Wie? Wie wird primärer Alkohol hergestellt? Durch Reaktion eines Grignard-Reagenz mit Formaldehyd. In der physikalischen Chemie lautet die Frage: Warum? Das Grignard-Reagenz und Formaldehyd tanzen auf Molekülebene. Man spricht von einem Reaktionsmechanismus, bei dem stärkere Verbindungen schwächere Verbindungen vom Parkett fegen. Wenn Sie wissen möchten, warum das so ist, ist dieses Buch genau richtig. Physical Chemistry: How Chemistry Works verfolgt einen neuen Ansatz bei der Vermittlung der Lerninhalte rund um die physikalische Chemie. Dieses moderne Lehrbuch soll Chemiestudenten im Hauptstudium für das Fachgebiet begeistern und auf die Anwendung der physikalischen Chemie in der Praxis vorbereiten. Praxisorientiert, leserfreundlich und modern sind die Beispiele, mit denen sich die physikalisch-chemischen Aspekte jedes Systems besser verstehen lassen. Studenten der anorganischen Chemie, organischen Chemie, analytischen Chemie und Biochemie erfahren alles Wissenswerte über die physikalische Chemie und wissen im Anschluss, was Synthesen, intermolekularen Wechselwirkungen und Materialeigenschaften sind. Studenten, die sich eingehender mit der physikalischen Chemie beschäftigen möchten, erleichtert dieses Lehrbuch diesen Schritt, denn es zeigt auch die Grenzen der Forschung auf.

Book Description
Concerned with production decline, shortages of new oil reserves, and increasing world energy demand, the oil sector continues to search for economic and efficient techniques to enhance their oil recovery from the existing oil field using several enhanced oil recovery techniques (EOR)methods. Despite its highefficiency, widely acclaimed potentials, and limitations, the Low Salinity Water Flooding (LSWF), hybrid, and nanotechnology applications have gained vast interest with promising future to increase ultimate oil recovery, tackle operational challenges, reduce environmental damage, and allow the highest feasible recoveries with lower production costs. This synergistic combination has opened new routes for novel materials with fascinating properties. This book aims to provide an overview of EOR technology such as LSWF, hybrid, and nanotechnology applications in EOR processes.
