Future of Glycerol Royal Society Of Chemistry
Książki / Literatura obcojęzyczna
By-products of global biodiesel manufacturing are a global fact and the immense amount of glycerol by-product stacking unsold until mid 2005 gave a visual image of the huge loss of energy and material resources. This was due to the lack of suitable conversion processes for this, the oldest organic molecule known to man, despite various experiments by some biodiesel producers. The large surplus of glycerol by-product which entered the chemical market has caused closure of existing glycerol plants and the discovery of processes that use glycerol as a raw material for the production of value-added chemicals and even of energy. This was followed by 3-4 years of intense research activity worldwide, where human chemical ingenuity opened up a number of practical avenues to convert glycerol into value added products of mass consumption. For instance, the batteries of your laptop and iPod, as well as your car's antifreeze will soon be based on glycerol, the same sweet viscous substance currently present in soaps. Reporting and commenting on such achievements this book aims to inform chemistry professionals, including managers and technologists, on the large potential of glycerol as versatile biofeedstock for the production of a variety of chemicals, polymers and fuels. Whilst filling a gap in the current literature, this nicely illustrated book is written in a clear, concise style and presents the numerous uses of glycerol as a new raw material which are starting to have an impact on industry worldwide. Elucidation of the principles governing the new chemistry of glycerol goes along with updated industrial information that is generally difficult to retrieve. Through its 10 chapters, the monograph tells the story of a chemical success -- that of converting glycerol into value added products -- and highlight the principles that made it possible. Whether as solvent, antifreeze, detergent, monomer for textiles or drug, new catalytic conversions of glycerol have been discovered that are finding application for the synthesis of products whose use range from everyday life to the fine chemical industry. Readers are also shown how a number of practical limitations posed by glycerol chemistry, such as the low selectivity encountered employing traditional stoichiometric and older catalytic conversions, were actually solved based on the understanding of the fundamental chemistry of glycerol and by application of catalysis science and technology. Readers also find a thorough discussion on the sustainability issues of bioglycerol production covering societal, environmental and economic dimensions to reflect the needs of politicians and citizens of today who require cross border research. By explaining the advantages and problems as well as offering solutions the book aids understanding as to whether biodiesel and glycerol refineries are convenient and economically sound. Chemical research on glycerol has shown that given a strong economic input, chemists are able to rapidly devise a whole set of new upgrading processes for the biorefinery and that the latter integrated unity for production energy and chemicals is not just dream of environmentally-minded scientists but an inevitable reality of today. Due to the ever decreasing energy return on energy invested, global society is being forced to switch from fossil to renewable fuels until cheap and abundant energy of solar origin becomes a reality. In this evolution, biofuels, particularly biodiesel, will certainly play a role and therefore, glycerol will be a key raw material for the biorefinery for many years to come. The book's users include industry's top managers and management consultants and also R&D and marketing managers. Along with technical content of a high quality, this is also a strategic book for top managers of the chemical, biofuel, oleochemical and detergent industries.
Networked and Distributed Predictive Control Springer, Berlin
Książki / Literatura obcojęzyczna
Networked and Distributed Predictive Control presents rigorous, yet practical, methods for the design of networked and distributed predictive control systems the first book to do so. The design of model predictive control systems using Lyapunov-based techniques accounting for the influence of asynchronous and delayed measurements is followed by a treatment of networked control architecture development. This shows how networked control can augment dedicated control systems in a natural way and takes advantage of additional, potentially asynchronous and delayed measurements to maintain closed loop stability and significantly to improve closed-loop performance. The text then shifts focus to the design of distributed predictive control systems that cooperate efficiently in computing optimal manipulated input trajectories that achieve desired stability, performance and robustness specifications but spend a fraction of the time required by centralized control systems. Key features of this book include: new techniques for networked and distributed control system design; insight into issues associated with networked and distributed predictive control and their solution; detailed appraisal of industrial relevance using computer simulation of nonlinear chemical process networks and wind- and solar-energy-generation systems; and integrated exposition of novel research topics and rich resource of references to significant recent work. A full understanding of Networked and Distributed Predictive Control requires a basic knowledge of differential equations, linear and nonlinear control theory and optimization methods and the book is intended for academic researchers and graduate students studying control and for process control engineers. The constant attention to practical matters associated with implementation of the theory discussed will help each of these groups understand the application of the book s methods in greater depth.
