Available in PDF, EPUB and Kindle. Book excerpt: All industrial distillation design of any consequence is now done using computer methods. Students need to be introduced to these new methods, shown the principles behind them, and taught how to use them more effectively and intelligently. This book is designed for use in a senior course in distillation design for the last undergraduate year or at postgraduate level. It is particularly useful for such a course because it integrates various disciplines (thermodynamics, design, control and distillation) that the student will have met separately in an earlier part of his course. The topics treated are: design, vapour/liquid equilibria data, binary distillation, multicomponent distillation, batch distillation, distillation systems, column internals, safety and control systems, pilot experiments and debottlenecking. Whereas most senior books on distillation concentrate on solution methods for the algebraic equations defining the separation in the column, this book concentrates on those areas which are the real concern of the distillation equipment designer. The text provides a link between the theory of distillation and industrial practice.

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: 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 [...]

This book was released on 2013-06-10 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, the nonsharp split and its effect to the synthesis of multicomponent distillation configurations are investigated. For any zeotropic mixture with N-component, two kinds of nonsharp splits can be introduced in a separation sequence, namely the symmetric nonsharp split which is fully sloppy split of the middle components, and the asymmetric split which is partially sloppy split of the middle components. First, with intended sharp and nonsharp splits, different distinct separation sequences can be formulated for a multicomponent distillation. For the distinct separation sequences, different ways to deal with the condensers and reboilers associated with submixtures of middle components are presented. It is shown that different traditional distillation configurations can be generated which may have equal to N-1 or more than N-1 columns. From the different traditional distillation configurations, the intensified distillation systems with less than or equal to N-1 columns are derived. It is shown that the combination of the individual columns in the traditional distillation configurations has dramatic effect to the generation of the intensified distillation systems. It is found that traditional distillation with more than N-1 columns gives more opportunities to synthesize the intensified distillation systems.

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.

Available in PDF, EPUB and Kindle. Book excerpt: In this chapter, an algorithm for the solution of the mathematical model featuring steady-state multicomponent distillation columns is analyzed and applied in the case study of the separation of hydrocarbon mixture. The development of the model has assumed each stage outlet streams in thermodynamic equilibrium in the phases liquid and vapor. The modeling of liquid was considerate and the non-ideality behavior was described by activity. The non-ideality of gas phase was calculated by Peng-Robinson equation of state. The model consists of a set of nonlinear algebraic equations. The algorithm and numerical procedure to solve a set of equations are presented in a sequential, general and very simple form. A methodology to produce the good initial guess was defined based on rude simplifications of the system. In the study case, the initial estimates generated by the method are very good, being only about 20% far from the simulation results and considering a tolerance of 10−10, the convergence was obtained with 28 iterations.
