This unique and comprehensive text considers all aspects of heat exchanger fouling from the basic science of how surfaces become fouled to very practical ways of mitigating the problem and from mathematical modelling of different fouling mechanisms to practical methods of heat exchanger cleaning. The problems that restrict the efficient operation of equipment are described and the costs, some of them hidden costs, that are associated with the fouling of heat exchangers are discussed. Some simple concepts and models of the fouling processes are presented as part of the introduction to the subject.Advice on the selection, design, installation and commissioning of heat exchangers to minimise fouling is given. A large part of the text is devoted to the use of chemical and other additives to reduce or eliminate the problem of fouling. Another large section is designed to give information on both on-line and off-line cleaning of heat exchangers. One of the difficulties faced by designers and operators of heat exchangers is anticipating the likely extent of fouling problems to be encountered with different flow streams. Another large section addresses the question and describes methods that have been used in attempting to define fouling potential. The book concludes with a chapter on how fouling information can be obtained using plant data, field tests and laboratory studies.

The Chemistry of Manganese, Technetium and Rhenium deals with the chemistry of manganese, technetium, and rhenium and covers topics ranging from the occurrence and metallurgy of all three elements to their properties and compounds. Among the compounds considered are manganese halides, cyanides, and oxides as well as carbonyls and organometallic compounds, thiocyanate complexes, and chalcogenides. This volume is divided into three sections and opens with an overview of the history and occurrence of manganese, along with its metallurgy, uses, and properties. A variety of manganese compounds are examined, including halides and cyanides, sulfides and selenides, tellurides and borates, and nitrites and nitrates. The next two sections focus on technetium and rhenium, their discovery, isolation, and general properties. Compounds of both elements are described, including hydridic compounds, cyanide and thiocyanate complexes, and oxoacids and salts. Perrhenic acid and the perrhenates are also discussed, together with chalcogenides and refractory compounds, carbonyls, and organometallic derivatives. This book will be a valuable source of information for inorganic chemists.

Manganese in the diet is nutritionally essential for normal physiologic functioning. However, excessive exposure to manganese has been associated with developmental, neurodegenerative and other disorders. The book comprehensively covers the toxicology of manganese. Leading investigators provide perspectives from toxicology, neuroscience, nutrition, molecular biology and risk assessment disciplines and chapters cover the toxicokinetics, toxicodynamic interactions and health effects of manganese, as well as its potential role in neurodegenerative diseases. A large section devoted to health effects presents the latest research that associates manganese exposure to potential human diseases. Any scientists, health professional or regulator involved with metal exposure and toxicology should find this volume essential reading. Students and researchers in neurotoxicology will also find this book a useful reference.

Metal oxides constitute one of the most amazing classes of materials with a wide range of properties. They exhibit a variety of phenomena, such as ferroelectricity, ferromagnetism and superconductivity. A new aspect of metal oxides -- colossal magnetoresistance exhibited by certain manganese oxides, in particular rare earth manganates of perovskite structure -- has received much attention in the last four years. Some of these oxides show 100% magnetoresistance and have much potential for technological applications. Previously this phenomenon was found only in layered and granular metallic materials. Studies of colossal magnetoresistance have led to the discovery of many other new phenomena and properties such as charge ordering and orbital ordering. In view of the importance of colossal magnetoresistance, charge ordering and related phenomena exhibited by oxides to the physics and chemistry of solid materials, it is necessary and timely to have a book dealing with these topics. This book begins with a review of the subject followed by contributions from a number of experts which cover the present status of the subject.
