A coal-fired fluidized bed combustion (FBC) system will be installed at the Owatonna Tool Company, Owatonna, Minnesota. Two FBC combustors will burn solid fuels: coal, petroleum coke, and wood and paper wastes. Crushed dolomitic limestone will be used to control sulfur emissions to EPA limits. The combustors will supply indirectly heated hot air and hot water for paint drying operations, washing processes, and space heating. The program is sponsored by the United States Department of Energy and the Owatonna Tool Company, and is one of five programs designed to demonstrate industrial applications of coal-fired fluidized bed equipment. The paper will describe the combustion system and the results of development tests with dolomitic limestone for sulfur emission control.

Principles of Industrial Chemistry Chris A. Clausen III & Guy Mattson The first book specifically designed to help the academically trained chemist make the transition to the real world of industry. It uses process development as a general theme to provide information normally acquired only through on-the-job training. The authors trace an industrial chemical process from idea stage to fully operational plant, discuss concepts in unit operation and their applications, and deal with such subjects as material accounting, energy accounting, mass transport, heat transfer, principles of kinetics, separation methods, instrumentation, economic concepts, and patent procedures. A valuable overview and insight into the industry. 1978 The Chemistry of Silica Solubility, Polymerization, Colloid and Surface Properties, and Biochemistry Ralph K. Iler Silica, the major component of the earth’s solid surface, the constituent of ordinary sand, and an essential material in many forms of life, is involved in many phases of modern technology and science. Its role in human disease, aging, and health is just beginning to be explored. Here is a comprehensive account of the basic chemistry involved in a wide range of research and development activities. Also a wealth of information on production and production control. Anyone involved with R&D or production in the many diverse fields and industries in which silica plays a vital role—chemistry, biology, medicine, agriculture, metallurgy, and mining—will find this book an invaluable reference. 1979 Fourth Edition of Faith, Keyes & Clark’s Industrial Chemicals Frederick A. Lowenheim & Marguerite K. Moran The latest updated edition of a manual whose popularity for a quarter-century attests to its usefulness as a handy reference—a concise, quick-study source of essential information on 145 commonly used chemicals. For each of them, the book covers such subjects as reaction and yield or recovery; material and energy requirements by quantities; detailed explanation of the process involved (with illustrations and flow diagram); uses of the end product and important by-products; economics of production; specifics on properties, grades, containers and regulations; list of manufacturers and plant locations; and volume of production and price ranges over the past two decades. A valuable time-saver. 1975
