Sulfur: History, Technology, Applications and Industry, Third Edition focuses on methods of production and their applications during various stages of industrial and technological use. 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 onto review native sulfur production in Sicily, once a major supplier to the world. The "Frasch method" is also covered in detail. 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 modern-day sulfur entrepreneurs, with a profile of various investors (from the reluctant to the private and institutional). Finally, the book forecasts the sulfur industry’s future and potential supply sources, such as worldwide oil sands.
