Energy efficiency in sugar manufacturing process


Book Description

Project Report from the year 2013 in the subject Engineering - Chemical Engineering, Wollo University (Kombolcha Institute Of Technology), course: Sugrar Technology, language: English, abstract: People were arguing that whether sugarcane is native to India or New Guinea. They do agree that ancient people liked it and carried with them in their migration and spread throughout south pacific area. Although sugar cane was possibly known in the holy land in biblical time only syrups could be obtained from it. In the 7th- 10th centuries AD, the Arabs spread sugarcane throughout their region of influence in the Mediterranean and eastwards. By the 12th century sugarcane reached Europe and Marco polo reported advanced sugar refining in china toward the end of 13th century. The ancient process for obtaining sugar consisted of boiling the juice until solids formed as the syrup cooled. Egyptians were using lime as purifying agent and carrying out recrystallization, which is still the main step in refining. The development of the sugar industry from the 16th century onward is closely associated with slavery, which supplied the largest amount of labor used at the time. The law cost of labor and price for sugar made many fortunes. The abolition of slavery introduces steam power as a replacement for the animal or human power that drove the cane mills. The use of steam in steady of direct firing was soon applied for evaporating the cane and following this vacuum pans and centrifuge were applied. The manufacturing of sugar is an energy intensive process which was the cause for deforestation, and then later replaced by bagasse burning and using energy efficiently by designing a multiple effect evaporators.

Sugarcane-based Biofuels and Bioproducts


Book Description

Sugarcane has garnered much interest for its potential as a viable renewable energy crop. While the use of sugar juice for ethanol production has been in practice for years, a new focus on using the fibrous co-product known as bagasse for producing renewable fuels and bio-based chemicals is growing in interest. The success of these efforts, and the development of new varieties of energy canes, could greatly increase the use of sugarcane and sugarcane biomass for fuels while enhancing industry sustainability and competitiveness. Sugarcane-Based Biofuels and Bioproducts examines the development of a suite of established and developing biofuels and other renewable products derived from sugarcane and sugarcane-based co-products, such as bagasse. Chapters provide broad-ranging coverage of sugarcane biology, biotechnological advances, and breakthroughs in production and processing techniques. This text brings together essential information regarding the development and utilization of new fuels and bioproducts derived from sugarcane. Authored by experts in the field, Sugarcane-Based Biofuels and Bioproducts is an invaluable resource for researchers studying biofuels, sugarcane, and plant biotechnology as well as sugar and biofuels industry personnel.




Modern Energy Economy in Beet Sugar Factories


Book Description

This book is devoted to the problems of identifying the potential for, designing and implementing, energy-saving measures in beet sugar factories. As the sugar industries in various countries differ considerably with respect to the economic conditions for factory operation and the level of technological development, the problem range is very broad. It may include the elimination of faulty or unreliable auxiliary equipment, or the introduction of simple improvements in vapour distribution schemes, in factories operated in countries where the need for efficient energy utilization has not really been very urgent until now. On the other hand, there are sugar factories in some other countries where considerable achievements have been made in energy saving but where further progress may still be possible if more advanced engineering problems are solved.The author takes an interdisciplinary approach to its subject aimed at demonstrating how the energy demand of a sugar factory can be affected by the interactions between a number of factors, namely: layout and parameters of the energy conversion and distribution processes; layout and parameters of the sugar manufacturing process and by-processes; characteristics of the equipment and control systems; completeness and accuracy of the energy monitoring systems. The book consists essentially of three parts. In Chapters 1 to 3, some theoretical background is given and engineering principles for creating efficient energy conversion and utilization subsystems in sugar factories are reviewed. The second part - Chapters 4 to 7 - discusses recent developments in these areas and their importance to energy conversion and utilization in sugar factories. The presentation is illustrated with suitable practically-oriented examples based mostly on the author's experience gained from nine years working with an engineering company specializing in the design, erection and modernization of sugar factories, as well as five years of consulting and research for the sugar industry. Short examples are presented in Chapters 1, 2, 3 and 7, while in the third part of the book (Chapters 8 and 9) summaries are given of real-life design analyses of energy subsystems of sugar factories, characterized by different levels of sophistication of the energy economy.The book thus provides a systematic review which will be helpful to managers and technologists in sugar factories where the problem may arise of choosing the most appropriate set of measures that best fit the factory's unique needs. It can also be used in university-level courses on the energy economy of sugar factories, and will be of interest to design engineers and specialists engaged in research in the area.

Energy Efficiency in Industry


Book Description

This book quantifies the potential for greater energy efficiency in industry on the basis of technology- and sector-related analyses. Starting from the methodological fundamentals, the first part discusses the electricity- and heat-based basic technologies and cross-sectional processes on the basis of numerous application examples. In addition to classic topics such as lighting and heat recovery, the study also covers processes that have received less attention to date, such as drying and painting. The second part is devoted to energy-intensive industries, in particular metal production and processing, the manufacture of the non-metallic materials cement and glass, and the chemical, paper, plastics and food industries. Both parts are concluded by placing them in a larger energy and economic context. The findings are condensed into checklists at many points and summarized in the overall view at the end to form generally applicable recommendations. This book is a translation of the original German 2nd edition Energieeffizienz in der Industrie by Markus Blesl and Alois Kessler, published by Springer-Verlag GmbH Germany, part of Springer Nature in 2017. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.
