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.

Available in PDF, EPUB and Kindle. Book excerpt: Distillation Principles and Practice Second Edition covers all the main aspects of distillation including the thermodynamics of vapor/liquid equilibrium, the principles of distillation, the synthesis of distillation processes, the design of the equipment, and the control of process operation. Most textbooks deal in detail with the principles and laws of distilling binary mixtures. When it comes to multi-component mixtures, they refer to computer software nowadays available. One of the special features of the second edition is a clear and easy understandable presentation of the principles and laws of ternary distillation. The right understanding of ternary distillation is the link to a better understanding of multi-component distillation. Ternary distillation is the basis for a conceptual process design, for separating azeotropic mixtures by using an entrainer, and for reactive distillation, which is a rapidly developing field of distillation. Another special feature of the book is the design of distillation equipment, i.e. tray columns and packed columns. In practice, empirical know-how is preferably used in many companies, often in form of empirical equations, which are not even dimensionally correct. The objective of the proposed book is the derivation of the relevant equations for column design based on first principles. The field of column design is permanently developing with respect to the type of equipment used and the know-how of two-phase flow and interfacial mass transfer.

Available in PDF, EPUB and Kindle. Book excerpt: Distillation has historically been the main method for separating mixtures in the chemical process industry. However, despite the flexibility and widespread use of distillation processes, they still remain extremely energy inefficient. Increased optimization and novel distillation concepts can deliver substantial benefits, not just in terms of significantly lower energy use, but also in reducing capital investment and improving eco-efficiency. While likely to remain the separation technology of choice for the next few decades, there is no doubt that distillation technologies need to make radical changes in order to meet the demands of the energy-conscious society. Advanced Distillation Technologies: Design, Control and Applications gives a deep and broad insight into integrated separations using non-conventional arrangements, including both current and upcoming process intensification technologies. It includes: Key concepts in distillation technology Principles of design, control, sizing and economics of distillation Dividing-wall column (DWC) – design, configurations, optimal operation and energy efficient and advanced control DWC applications in ternary separations, azeotropic, extractive and reactive distillation Heat integrated distillation column (HIDiC) – design, equipment and configurations Heat-pump assisted applications (MVR, TVR, AHP, CHRP, TAHP and others) Cyclic distillation technology – concepts, modeling approach, design and control issues Reactive distillation – fundamentals, equipment, applications, feasibility scheme Results of rigorous simulations in Mathworks Matlab & Simulink, Aspen Plus, Dynamics and Custom Modeler Containing abundant examples and industrial case studies, this is a unique resource that tackles the most advanced distillation technologies – all the way from the conceptual design to practical implementation.

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 Effect to Reflux Ration on Separation of Azeotropic Mixtures in Batch Distillation Column written by Wan Norazlinda Wan Zakaria and published by . This book was released on 2010 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study is to investigate the effect of different reflux ratio on separation of azeotropic mixtures. The azeotropic mixtures used were Ethanol/Water, MTBE/Methanol and IPA/Water. The experimental studied were conducted using Bubble Cap Distillation with 10 numbers of stages at 1 atm. The composition of feed mixtures used were 40:60 v/v. In terms of reflux ratios it was set at 1.1, 1.2, 1.3 and 1.4. The product was collected from each experiment and analyzed using refractometer to determine its concentration. The standard curve of binary mixtures of each mixtures were used for quantifying the composition in the collecting samples. From the results obtained, best reflux ratio for Ethanol/Water is 1.1 (95.8%), 1.2 for IPA/Water ( 57.64 mol%) and 1.2 for MTBE/Methanol (47.57%). The results obtained were compared with the vapour composition of binary mixtures for ordinary distillation process which are without reflux ratio. By comparing the result with the data of the vapor composition for ordinary distillation, the best reflux ratio was determined. These binary mixtures cannot be separated completely by ordinary distillation because of closed boiling point between each component which formed the azeotrope. When two mixtures were mixed, the intermolecular attraction forces in all liquid may cause the mixture to form certain inseparable composition (where vapour and liquid composition) at equilibrium are equal. Further separation can be achieved by controlling the reflux ratio of the distillation process to improve the separation efficiency. This study verified that reflux ratio influence the efficiency of the column.
