Dieses leicht verständliche Buch stellt unkonventionelle Technologien für die Konstruktion von Wärmetauschern vor, die in der Lage sind, Lösungen für wichtige Probleme in der Prozess- und Energieerzeugungsindustrie zu bieten. Es zeigt die Vorteile und Grenzen dieser innovativen Wärmetauscher auf, diskutiert Mikro- und Nanostrukturoberflächen und mikroskalige Geräte und stellt Kissenplatten-, Spiral- und Streckmetallumlenkungskonzepte vor. Es bietet Schritt-für-Schritt-Arbeitsbeispiele, die Anleitungen für die Entwicklung einer ersten Konfiguration liefern und durch klare, detaillierte Zeichnungen und Bilder unterstützt werden.Es gibt verschiedene Arten von Wärmetauschern, die in allen Bereichen der Industrie zu Kühl- oder Heizzwecken eingesetzt werden, auch in Verbrennungsmotoren. Der Markt wurde 2012 auf 42,7 Mrd. U$ geschätzt, und die weltweite Nachfrage nach Wärmetauschern verzeichnet ein jährliches Wachstum von etwa 7,8 %. Es wird erwartet, dass der Marktwert im Jahr2016 57,9 Mrd. U$ erreichen und sich bis 2020 auf 78,16 Mrd. U$ belaufen wird.Als wertvolle Einführung für Studenten und Forscher bietet dieses Buch klare und prägnante Informationen für Wärmetechniker, Maschinenbauingenieure, Verfahrenstechniker und Wärmetauscherspezialisten.

This accessible book presents unconventional technologies in heat exchanger design that have the capacity to provide solutions to major concerns within the process and power-generating industries. Demonstrating the advantages and limits of these innovative heat exchangers, it also discusses micro- and nanostructure surfaces and micro-scale equipment, and introduces pillow-plate, helical and expanded metal baffle concepts. It offers step-by-step worked examples, which provide instructions for developing an initial configuration and are supported by clear, detailed drawings and pictures.Various types of heat exchangers are available, and they are widely used in all fields of industry for cooling or heating purposes, including in combustion engines. The market in 2012 was estimated to be U$ 42.7 billion and the global demand for heat exchangers is experiencing an annual growth of about 7.8 %. The market value is expected to reach U$ 57.9 billion in 2016, and approach U$ 78.16 billion in 2020.Providing a valuable introduction to students and researchers, this book offers clear and concise information to thermal engineers, mechanical engineers, process engineers and heat exchanger specialists.

Covering the latest technologies in process engineering, this handbook and ready reference features high pressure processing, alternative solvents and processes, extraction technologies and biotransformations -- describing greener, more efficient and sustainable techniques. The result is an expert account of engineering details from lab-scale experiments to large-scale industrial design. The major focus is on the engineering aspects of extraction with organic and supercritical solvents, ionic liquids or surfactant solutions, and is supplemented by aspects of both up- and downstream processing, biotransformation, as well as a survey of typical products in food, pharmaceutical and cosmetic applications. This is rounded off by market developments, economic considerations and regulations requirements in the fieldAuthored by experts from leading industrial and academic institutions, this is essential reading for the hands-on scientist and office manager alike.

This booklet is designed to bridge the gap between handbooks and technical literature and aims at graduate students or experienced readers. Commercial flow sheeting simulation software is increasingly available and is used in the early steps of process design in industry. As to this, more sophisticated and precise models based on activities instead of concentrations should be used. After an introductory chapter there is in Chapter 2 an intensive discussion of reactive phase equilibria of ionic and non-ionic solutes based on chemical potentials. Chapter 3 introduces to multicomponent diffusion and mass transfer. However, the main focus is on the reactive mass transfer on rigid and mobile surfaces where the interfacial reaction, molecular diffusion and adsorption layers are decisive. The respective extraction of zinc with a cation exchanger and of acetic acid with an anion exchanger is discussed as case studies. Since adsorption layers and surfactants have a major impact on liquid-liquid extraction efficiency, the final chapter reviews several tech­ niques which make use of polymeric species in an extractive process. A short review is also given on extraction apparatus and the hydrodynamics (hydraulic design, droplet populance balances) of columns. Much of the booklet is based on the PhD works of C. Czapla (2000), G. Modes (2000), H. Klocker (1996), T. Kronberger (1995), M. Marters (2000), M. Roos (2000), M. Traving (2000) and B. Wachter (1996) who I wish to thank for their fruitful contributions.
