Modern Alcohol Technology (Yue Guojun)

Thread Content

Ethanol in the Word version of Modern Alcohol Technology is an excellent fuel, as well as an effective agent for improving the quality of fuels. Ethanol is an oxygenator for fuel oils; it increases the oxygen content in gasoline, enabling more complete combustion and thus achieving energy savings and environmental protection ； Ethanol possesses excellent anti-knock properties; its octane rating is generally above 120, which helps to significantly improve the anti-knock index of gasoline ； Currently, massive market demand is providing the alcohol industry with unprecedented opportunities for growth. The application of high-tech fields such as bioengineering, energy-saving technologies, and computers in the alcohol industry has brought about fundamental changes to this sector, injecting new vitality into an industry that had been stagnant for many years. Today, there have been significant improvements in terms of product quality, production processes, environmental protection, control levels, as well as various consumption indicators, which has allowed the alcohol industry, once limited in its possibilities for development, to regain its strength and vitality. Against this backdrop, it sparked the author’s curiosity to re-examine the issue of alcohol technology, and inspired the enthusiasm and inspiration to write this book. As is well known, the alcohol production process consists of two main parts: the biological reaction process and the separation process. The biological reaction process is also a type of reaction process. Drawing on his many years of experience in production as well as his tenure in senior management positions at COFCO Group, Yue Guojun has been able to grasp the development trends in the alcohol industry. From a forward-looking perspective, he proposed using process engineering methods to analyze the alcohol production process. The main thread of this book highlights this idea; it adopts the principles of process engineering to analyze the alcohol production process. Chapter 4, on the fermentation of saccharified mash, discusses the factors affecting fermentation, including the impact of fluid flow and mixing ； The design calculations for fermentation tanks include the determination of residence time distribution, as well as the use of the plug flow model and the multi-stage completely mixed reactor cascade model theory to calculate the conversion rate; a calculation program is also provided ； Finally, new fermentation technologies were introduced ； Chapter 3 describes the laboratory research results on the variation patterns of mash viscosity in the liquefaction and saccharification processes. The book consists of eight chapters: an introduction, Chapter 1 on the raw materials and auxiliary substances used in alcohol production, Chapter 2 on the pretreatment processes of raw materials as well as the gelatinization of starch slurry, Chapter 3 on the liquefaction and saccharification processes, Chapter 4 on the fermentation of the saccharified mash, Chapter 5 on the distillation of the matured mash and the production of anhydrous alcohol, Chapter 6 on the comprehensive utilization of by-products from alcohol plants and wastewater treatment, and Chapter 7 on the process design for modern alcohol plants. The entire book was planned by Yue Guojun; the introduction, Chapter 5, Chapter 6, and Chapter 7 were written by Dong Hongxing ； Chapters 1, 2, 3, and 4 were written by Yang Xiaoguang. In the process of compiling this book, experience and practical engineering results from previous efforts in alcohol plant design were taken into account, with an effort to reflect modern principles and methods for designing alcohol plants in its content. Otch’s textbook on alcohol technology from the United States has added a fresh perspective to certain aspects of this book. This book primarily highlights the design concepts of modern alcohol plants and introduces the use of computers in plant design. Many of the examples in the book come from the author’s practical work in production and research. The design examples in the book were provided by COFCO Bioenergy Company (Zhaodong), offering a solid background in industrial production. http://ishare.iask.sina.com.cn/f/11511304.html
