By some measure the most widely produced chemical in the world today, sulfuric acid has an extraordinary range of modern uses, including phosphate fertilizer production, explosives, glue, wood preservative and lead-acid batteries. An exceptionally corrosive and dangerous acid, production of sulfuric acid requires stringent adherence to environmental regulatory guidance within cost-efficient standards of production. This work provides an experience-based review of how sulfuric acid plants work, how they should be designed and how they should be operated for maximum sulfur capture and minimum environmental impact. Using a combination of practical experience and deep physical analysis, Davenport and King review sulfur manufacturing in the contemporary world where regulatory guidance is becoming ever tighter (and where new processes are being required to meet them), and where water consumption and energy considerations are being brought to bear on sulfuric acid plant operations. This 2e will examine in particular newly developed acid-making processes and new methods of minimizing unwanted sulfur emissions. The target readers are recently graduated science and engineering students who are entering the chemical industry and experienced professionals within chemical plant design companies, chemical plant production companies, sulfuric acid recycling companies and sulfuric acid users. They will use the book to design, control, optimize and operate sulfuric acid plants around the world. Unique mathematical analysis of sulfuric acid manufacturing processes, providing a sound basis for optimizing sulfuric acid manufacturing processes Analysis of recently developed sulfuric acid manufacturing techniques suggests advantages and disadvantages of the new processes from the energy and environmental points of view Analysis of tail gas sulfur capture processes indicates the best way to combine sulfuric acid making and tailgas sulfur-capture processes from the energy and environmental points of view Draws on industrial connections of the authors through years of hands-on experience in sulfuric acid manufacture

This book describes and explains the methods by which three related ores and recyclables are made into high purity metals and chemicals, for materials processing. It focuses on present day processes and future developments rather than historical processes. Nickel, cobalt and platinum group metals are key elements for materials processing. They occur together in one book because they (i) map together on the periodic table (ii) occur together in many ores and (iii) are natural partners for further materials processing and materials manufacturing. They all are, for example, important catalysts - with platinum group metals being especially important for reducing car and truck emissions. Stainless steels and CoNiFe airplane engine super alloys are examples of practical usage. The product emphasises a sequential, building-block approach to the subject gained through the author's previous writings (particularly Extractive Metallurgy of Copper in four editions) and extensive experience. Due to the multiple metals involved and because each metal originates in several types of ore - e.g. tropical ores and arctic ores this necessitates a multi-contributor work drawing from multiple networks and both engineering and science. Synthesizes detailed review of the fundamental chemistry and physics of extractive metallurgy with practical lessons from industrial consultancies at the leading international plants Discusses Nickel, Cobalt and Platinum Group Metals for the first time in one book Reviews extraction of multiple metals from the same tropical or arctic ore Industrial, international and multidisciplinary focus on current standards of production supports best practice use of industrial resources

Flash Smelting: Analysis, Control and Optimization deals with the analysis, control, and optimization of flash smelting. This book explores flash smelting in general and Outokumpu and Inco flash smelting in particular, and also presents a mathematical description for the flash smelting process. A set of mass and heat balance equations that can be used to describe steady state smelting under autogenous or nearautogenous smelting conditions is developed. This text has 20 chapters and begins with an overview of flash smelting and its products; the main raw materials of copper flash smelting; chemical reactions in the flash furnace; impurities in the concentrates that are fed to the flash furnace; and the operation of industrial flash furnaces. Attention then turns to Outokumpu flash smelting, Inço flash smelting, and mathematical representation of flash smelting. The chapters that follow focus on the effects of blast preheat on flash smelting; the combustion of fossil fuel in the flash furnace; and the effect of matte grade on the fossil fuel, industrial oxygen, and blast preheat requirements of flash smelting. Equations are used to determine the effects of such factors as concentrate composition, blast temperature, and dust carryout, and as the basis for optimizing and controlling the flash smelting process. This book will be of interest to both mathematicians and metallurgists.

"Vor ungefahr zwei Jahren trat die Firma Urban & Schwarzenberg mit dem Vorschlage an mich heran, eine Enzyklopadie der technischen Chemie herauszugeben, die ungefahr 10 Bande umfassen und im Verlaufe von 3 - 4 Jahren erscheinen sollte. So wurde denn in fast 2jahriger angestrengter Vorarbeit der Grundplan fur das gesamte Werk entworfen und die Anordnung sowie der Umfang der einzelnen aufzunehmenden Artikel festgestellt. Den Gegenstand des auf breitester Basis angelegten Werkes bilden nicht nur die chemische Grossindustrie und die Metallhuttenkunde mit ihren maschinellen und apparativen Hilfsmitteln, sondern auch die zahlreichen Grenzgebiete, welche sich mit der stofflichen Veranderung oder der Veredelung der Materie uberhaupt befassen. Dem enzyklopadischen Charakter des Werkes entsprechend, musste die Anordnung des Stoffes alphabetisch sein. Doch schien es im Interesse der Ubersichtlichkeit und zur Vermeidung von Wiederholungen zweckmassig, Gebiete, welche stofflich eng zusammen gehoren, auch ausserlich aneinander zu schliessen. Um die Benutzung des Werkes in jeder nur denkbaren Weise zu erleichtern, dienen zur schnelleren Auffindung einer Substanz ausser den zahlreichen Hinweisen die jedem Bande beigegebenen sehr ausfuhrlichen Sachregister; den Schluss soll ein Generalregister bilden, welches die ganze Enzyklopadie umfassen wird. Fur die Rechtschreibung gilt durchweg die wissenschaftliche Schreibweise nach Jansen." [...] Der hier vorliegende achte Band der "Enzyklopadie der technischen Chemie" erlautert von "Natriumverbindungen" bis "Salophen" und ist mit uber 250 historischen Abbildungen illustriert. Dieses Buch ist ein unveranderter Nachdruck der Originalausgabe der zweiten neu bearbeiteten Auflage von 1931."

The Iron Blast Furnace: Theory and Practice presents theoretical, experimental, and operational evidence about the iron blast furnace as well as a mathematical description of its operation. This book includes a set of equations that accurately describe stoichiometric and enthalpy balances for the process and which are consistent with observed temperatures and compositions in the furnace stack. These equations, which have been devised on the basis of the Rist approach, show the effects of altering any blast-furnace variable on the other operating requirements of the process. This monograph is comprised of 14 chapters and begins with a brief description of the blast-furnace process. The next chapter takes a look inside the furnace, paying particular attention to its behavior in front of the tuyères and the kinetics of the coke gasification reaction. The reader is then introduced to the thermodynamics and stoichiometry of the blast-furnace process; enthalpy balance for the bottom segment of the furnace; the effects of tuyères injectants on blast-furnace operations; and blast-furnace optimization by linear programming. A number of important variables covered by the equations are discussed, including hydrocarbon injection at the tuyères, oxygen enrichment of the blast, moisture, limestone decomposition, coke reactivity, and metalloid reduction. The effects of many of these variables are illustrated numerically in the text while others are demonstrated in sets of problems that follow each chapter. This text will be a valuable resource for metallurgists and materials scientists.
