Book Description
In the context of wastewater treatment, Bioelectrochemical Systems (BESs) have gained considerable interest in the past few years, and several BES processes are on the brink of application to this area. This book, written by a large number of world experts in the different sub-topics, describes the different aspects and processes relevant to their development. Bioelectrochemical Systems (BESs) use micro-organisms to catalyze an oxidation and/or reduction reaction at an anodic and cathodic electrode respectively. Briefly, at an anode oxidation of organic and inorganic electron donors can occur. Prime examples of such electron donors are waste organics and sulfides. At the cathode, an electron acceptor such as oxygen or nitrate can be reduced. The anode and the cathode are connected through an electrical circuit. If electrical power is harvested from this circuit, the system is called a Microbial Fuel Cell; if electrical power is invested, the system is called a Microbial Electrolysis Cell. The overall framework of bio-energy and bio-fuels is discussed. A number of chapters discuss the basics – microbiology, microbial ecology, electrochemistry, technology and materials development. The book continues by highlighting the plurality of processes based on BES technology already in existence, going from wastewater based reactors to sediment based bio-batteries. The integration of BESs into existing water or process lines is discussed. Finally, an outlook is provided of how BES will fit within the emerging biorefinery area.

Book Description
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

Book Description
This attractive volume presents the history, characteristics, and uses for that vibrant yellow element, sulfur. Commercial sulfuric acid production from the early 16th century until today is reviewed, spanning the Ancient and Renaissance periods, the Industrial Age (to which sulfur was vitally important), and the Sulfur War of 1840. The book introduces "the Sulfur Age" and the processes of this period -- such as the Nordhausen, Bell and Leblanc methods --, then goes on to review native sulfur production in Sicily, once a major supplier to the world. Colorful characters abound here, including the Gabelloti, Doppioni, and wine merchants. The focus shifts to Frasch Sulfur production, with a portrait of Herman Frasch, his life and career, and a look at areas touched by his legacy (e.g., Texas, Mexico, Poland and Iraq). Moving to present day, the book presents "recovered" sulfur -- derived from sour gas and oil -- which constitutes 90% of today's elemental sulfur supply, and looks to Canada, a powerhouse supplier of Recovered Sulfur. An entire chapter is devoted to the modern-day sulfur entrepreneur, with a profile of various investors (from the reluctant to the private and institutional), and evaluates the benefits of adopting "revolutionary technologies". Finally, the book forecasts the sulfur industry's future and potential supply sources, such as worldwide oil sands. If you need a single, comprehensive book on sulfur, this is a book for your library.
