Download or read book Design and Control of Distillation Systems for Separating Azeotropes written by William L. Luyben and published by John Wiley & Sons. This book was released on 2011-12-06 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hands-on guidance for the design, control, and operation of azeotropic distillation systems Following this book's step-by-step guidance, readers learn to master tested and proven methods to overcome a major problem in chemical processing: the distillation and separation of azeotropes. Practical in focus, the book fully details the design, control, and operation of azeotropic distillation systems, using rigorous steady-state and dynamic simulation tools. Design and Control of Distillation Systems for Separating Azeotropes is divided into five parts: Fundamentals and tools Separations without adding other components Separations using light entrainer (heterogeneous azeotropic distillation) Separations using heavy entrainer (extractive distillation) Other ways for separating azeotropes The distillation methods presented cover a variety of important industrial chemical systems, including the processing of biofuels. For most of these chemical systems, the authors explain how to achieve economically optimum steady-state designs. Moreover, readers learn how to implement practical control structures that provide effective load rejection to manage disturbances in throughput and feed composition. Trade-offs between steady-state energy savings and dynamic controllability are discussed, helping readers design and implement the distillation system that best meets their particular needs. In addition, economic and dynamic comparisons between alternative methods are presented, including an example of azeotropic distillation versus extractive distillation for the isopropanol/water system. With its focus on practical solutions, Design and Control of Distillation Systems for Separating Azeotropes is ideal for engineers facing a broad range of azeotropic separation problems. Moreover, this book is recommended as a supplemental text for undergraduate and graduate engineering courses in design, control, mass transfer, and bio-processing.

Download or read book Solvent Recovery Handbook written by Ian McN. Smallwood and published by CRC Press. This book was released on 2002 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pressure is on to cut plant emissions while still maintaining a cost-effective operation. Choosing the best solvent, being aware of potential problems, and the recovery of solvents has never been so important. Traditionally, solvents had been chosen on the basis of whether they can do the job effectively and economically. However, with regulations on exposure to solvent vapors becoming more stringent, selecting the solvent that meets regulatory, efficiency, and economical criteria as early as possible in the process has become paramount. Solvent Recovery Handbook, Second Edition sets out the physical properties of the fifty most commonly used solvents. The book supplies information on their behavior during and after use, health and fire hazards, the photochemical ozone creation potential (POCP), and recovery processes including practical aspects of the design and operation of batch stills. It delivers state-of-the art coverage of every available recovery and disposal technology - including removing solvents from gas, water, and residues, separating used solvents, and drying solvents. What's more, you'll find fact-filled sections on the latest equipment, safe effective operating procedures, choosing solvents with recovery in mind, and much more. Updated and expanded, Ian Smallwood's Solvent Recovery Handbook, Second Edition hands you all the practical tools you need to efficiently and cost-effectively process harmful organic solvents after re-capture.

Download or read book Separation of a highly nonideal mixture for solvent recovery written by Andreas Raab and published by diplom.de. This book was released on 2003-01-15 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inhaltsangabe:Abstract: The separation of complex nonideal mixtures is a common problem in the process industries. The solvent recovery is an important task for chemical engineers to minimize burden upon the environment due to exhaustive use of solvents. The recovery of the individual components is complicated by the highly nonideal features of these mixtures. The separation of such highly nonideal mixtures can be limited by the presence of azeotropes, which can create distillation boundaries. These distillation boundaries are forming distillation regions which are difficult to overcome with the standard rectification. Distillation systems for these highly nonideal azeotropic mixtures are particularly difficult to design and to operate in an efficient way. In printing companies often four component mixtures of ethanol, ethyl acetate, isopropyl acetate, and water arise as waste. A separation scheme of multicomponent azeotropic distillation is developed and successfully used for a highly nonideal quaternary mixture. The composition of the mixture in mass percent is ethanol 30%, water 20%, ethyl acetate 25% and isopropyl acetate with 20%. The rest of the mixture (5%) consists of n-propane, isopropane, cyclohexane, and etoxypropane. For the further investigation just the quaternary mixture is examined. Generally, every component should be recovered as pure as possible from the mixture. In the mixture namely five binary and two ternary azeotropes are formed by the components. Based on the synthesis procedure proposed by Rev et al. and Mizsey et al. a new separation technology is developed followed up the vapor-liquid-liquid equilibrium behavior of the mixture. They have recommended a general framework for designing feasible schemes of multicomponent azeotropic distillation. This procedure recommends to study in detail the vapor-liquid-liquid equilibrium data to explore immiscibility regions, azeotropic points, and separatrices for ternary and quaternary regions. On the behalf of the VLLE data the set of feasible separation structures is explored. This procedure is followed and a new separation structure is developed and tested experimentally. First, the quaternary mixture is separated into two ternary mixtures by distillation. The two ternary mixtures containing ethyl acetate, ethanol, water and isopropyl acetate, ethanol, water, respectively. Due to the analogous behavior of the two ternary mixtures similar separation cycles can be designed. The two [...]

Download or read book Chemical Engineering in the Pharmaceutical Industry written by David J. am Ende and published by John Wiley & Sons. This book was released on 2011-03-10 with total page 1431 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with various unique elements in the drug development process within chemical engineering science and pharmaceutical R&D. The book is intended to be used as a professional reference and potentially as a text book reference in pharmaceutical engineering and pharmaceutical sciences. Many of the experimental methods related to pharmaceutical process development are learned on the job. This book is intended to provide many of those important concepts that R&D Engineers and manufacturing Engineers should know and be familiar if they are going to be successful in the Pharmaceutical Industry. These include basic analytics for quantitation of reaction components– often skipped in ChE Reaction Engineering and kinetics books. In addition Chemical Engineering in the Pharmaceutical Industry introduces contemporary methods of data analysis for kinetic modeling and extends these concepts into Quality by Design strategies for regulatory filings. For the current professionals, in-silico process modeling tools that streamline experimental screening approaches is also new and presented here. Continuous flow processing, although mainstream for ChE, is unique in this context given the range of scales and the complex economics associated with transforming existing batch-plant capacity. The book will be split into four distinct yet related parts. These parts will address the fundamentals of analytical techniques for engineers, thermodynamic modeling, and finally provides an appendix with common engineering tools and examples of their applications.
