Applications of Markov chains in chemical engineering / par Tamir,, Abraham. Publication : . 1 online resource (xi, 604 pages) : , Markov chains make it possible to predict the future state of a system from its present state ignoring its past history. Surprisingly, despite the widespread use of Markov chains in many areas of science and technology, their applications in chemical engineering have been relatively meager. A possible reason for this phenomenon might be that books containing material on this subject have been written in such a way that the simplicity of Markov chains has been shadowed by the tedious mathematical derivations. Thus, the major objective of writing this book has been to try to change this situation. There are many advantages, detailed in Chapter 1, of using the discrete Markov-chain model in chemical engineering. Probably, the most important advantage is that physical models can be presented in a unified description via state vector and a one-step transition probability matrix. Consequently, a process is demonstrated solely by the probability of a system to occupy or not occupy a state. The book has been written in an easy and understandable form, where complex mathematical derivations are abandoned. The fundamentals of Markov chains are presented in Chapter 2 with examples from the bible, art and real life problems. An extremely wide collection is given of examples viz., reactions, reactors, reactions and reactors as well as combined processes, including their solution and a graphical presentation of it, all of which demonstrates the usefulness of applying Markov chains in chemical engineering.

Arburg practical guide to injection moulding / par Goodship,, V. Publication : [S.l.] : Smithers Rapra Press, 2004 . 276 p. ; , This Practical Guide to Injection Moulding is based on course material used by ARBURG in training operators of injection moulding machines. It comes from many years of experience in this field and has been edited by an expert injection moulder at Warwick University. It will be of use to experts looking to fill gaps in their knowledge base and to those new to the industry. The factors involved in injection moulding, from material properties and selection to troubleshooting faults, are all examined in this book. It covers the equipment types in use and machine settings for different types of plastics. Material flow is critical in moulding and there are sections covering rheology and viscosity. High temperature can lead to poor quality mouldings due to material degradation and this is discussed. There are an exceptional number of figures in this text, with many photographs of machinery and mouldings to illustrate key points. There are also numerous tables listing key properties and processing parameters. Flow charts are included in the chapter on troubleshooting to indicate what can be changed to resolve common problems. Injection moulding in the Western World is becoming increasingly competitive as the manufacturing base for many plastics materials has moved to the East. Thus Western manufacturers have moved into more technically difficult products and mouldings to provide more added value and maintain market share. Technology is becoming more critical, together with innovation and quality control. There is a chapter on advanced processing in injection moulding covering multi-material and assisted moulding technologies. This Guide will assist progress in developing good technical skills and appropriate processing techniques for the range of plastics and products in the marketplace. 30 cm.

Biofuels and bioenergy : processes and technologies / par Lee, Sunggyu. Publication : Boca Raton, FL : Taylor and Francis , 2012 . xvii, 323 pages : , "Preface Humans have a long history of using a wide variety of biomass resources as sources of energy and fuel. The discovery and use of fossil energy, represented largely by coal, natural gas, and petroleum, have drastically reduced the utilization of biomass fuels. The technologies of generating electricity using biomass, producing bioliquid fuels, and powering motor vehicles using bioalcohols and blended gasolines have been developed and practiced since the early twentieth century. Up until recently, however, development interest in biofuels had lessened due to the availability of relatively inexpensive fossil energy resources as well as the handling and transportation convenience of these conventional fuel sources. Due to the strong growth of global transportation fuel demand, sharply escalating worldwide fossil energy prices, fear over the dwindling supply of petroleum and natural gas for the near future, and credible evidence linking global warming and climate change issues with the emission of greenhouse gases, global interest and R&D efforts in renewable alternative fuels have become intense and fiercely competitive, targeting both short- and long-term solutions to alternative energy needs. Although there are a number of options and routes for energy sustainability and independence via renewable alternative energy, bioenergy and biofuels certainly possess outstanding potential to provide solutions and relief to many of the immediate, intermediate, and long-term societal needs of clean energy and their associated challenges"-- 25 cm.

Biotransformations in organic chemistry : a textbook / par Faber, Kurt. Publication : [S.l.] : Springer, 2004 . 454 p. ; , The use of biocatalysts, employed either as isolated enzymes or whole microbial cells, offers a remarkable arsenal of highly selective transformations for state-of-the-art synthetic organic chemistry. Over the last two decades, this methodology has become an indispensable tool for asymmetric synthesis, not only at the academic level, but also on an industrial scale. This well-established textbook on biocatalysis provides a basis for undergraduate and graduate courses in modern organic chemistry, as well as a condensed introduction into this field. After a basic introduction into the use of biocatalysts ? principles of stereoselective transformations, kinetics and enzyme properties ? the different types of reactions are explained according to the 'reaction principle', such as hydrolysis, reduction, oxidation, C-C bond formation, etc. Special techniques, such as the use of enzymes in organic solvents, immobilization techniques and the use of modified enzymes, are treated in a separate section. A final chapter deals with the basic rules for the safe and practical handling of biocatalysts. In this revised and corrected 5th edition, emphasis has been given to an improved didactic style in order to facilitate a deeper understanding of the underlying principles. New developments, such as dynamic resolution, stereo-inversion and enantio-convergent processes are included. 23 cm.
