Book Description
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 [...]

Book Description
The Definitive, Up-to-Date, Student-Friendly Guide to Separation Process Engineering—With More Mass Transfer Coverage and a New Chapter on Crystallization Separation Process Engineering, Fourth Edition, is the most comprehensive, accessible guide available on modern separation processes and the fundamentals of mass transfer. In this completely updated edition, Phillip C. Wankat teaches each key concept through detailed, realistic examples using real data—including up-to-date simulation practice and spreadsheet-based exercises. Wankat thoroughly covers each separation process, including flash, column, and batch distillation; exact calculations and shortcut methods for multicomponent distillation; staged and packed column design; absorption; stripping; and more. This edition provides expanded coverage of mass transfer and diffusion, so faculty can cover separations and mass transfer in one course. Detailed discussions of liquid-liquid extraction, adsorption, chromatography, and ion exchange prepare students for advanced work. Wankat presents coverage of membrane separations, including gas permeation, reverse osmosis, ultrafiltration, pervaporation, and applications. An updated chapter on economics and energy conservation in distillation adds coverage of equipment costs. This edition contains more than 300 new, up-to-date homework problems, extensively tested in undergraduate courses at Purdue University and the University of Canterbury (New Zealand). Coverage includes New chapter on crystallization from solution, including equilibrium, chemical purity, crystal size distribution, and pharmaceutical applications Thirteen up-to-date Aspen Plus process simulation labs, adaptable to any simulator Eight detailed Aspen Chromatography labs Extensive new coverage of ternary stage-by-stage distillation calculations Fraction collection and multicomponent calculations for simple batch distillation New mass transfer analysis sections on numerical solution for variable diffusivity Mass transfer to expanding or contracting objects, including ternary mass transfer Expanded coverage of pervaporation Updated Excel spreadsheets offering more practice with distillation, diffusion, mass transfer, and membrane separation problems

The Definitive, Learner-Friendly Guide to Chemical Engineering Separations--Extensively Updated, Including a New Chapter on Melt Crystallization Efficient separation processes are crucial to addressing many societal problems, from developing new medicines to improving energy efficiency and reducing emissions. Separation Process Engineering, Fifth Edition, is the most comprehensive, accessible guide to modern separation processes and the fundamentals of mass transfer. In this completely updated edition, Phillip C. Wankat teaches each key concept through detailed, realistic examples using actual data--with up-to-date simulation practice, spreadsheet-based exercises, and references. Wankat thoroughly covers each separation process, including flash, column, and batch distillation; exact calculations and shortcut methods for multicomponent distillation; staged and packed column design; absorption; stripping; and more. His extensive discussions of mass transfer and diffusion enable faculty to teach separations and mass transfer in a single course. And detailed material on liquid-liquid extraction, adsorption, chromatography, and ion exchange prepares students for advanced work. New and updated content includes melt crystallization, steam distillation, residue curve analysis, batch washing, the Shanks system for percolation leaching, eutectic systems, forward osmosis, microfiltration, and hybrid separations. A full chapter discusses economics and energy conservation, including updated equipment costs. Over 300 new and updated homework problems are presented, all extensively tested in undergraduate courses at Purdue University. New chapter on melt crystallization: solid-liquid phase equilibrium, suspension, static and falling film layer approaches, and 34 questions and problems New binary VLE equations and updated content on simultaneous solutions New coverage of safety and fire hazards New material on steam distillation, simple multi-component batch distillation, and residue curve analysis Expanded discussion of tray efficiencies, packed column design, and energy reduction in distillation New coverage of two hybrid extraction with distillation, and the Kremser equation in fractional extraction Added sections on deicing with eutectic systems, eutectic freeze concentration, and scale-up New sections on forward osmosis and microfiltration Expanded advanced content on adsorption and ion exchange including updated instructions for eight detailed Aspen Chromatography labs Discussion of membrane separations, including gas permeation, reverse osmosis, ultrafiltration, pervaporation, and applications Thirteen up-to-date Aspen Plus process simulation labs, adaptable to any simulator This guide reflects an up-to-date understanding of how modern students learn: designed, organized, and written to be exceptionally clear and easy to use. It presents detailed examples in a clear, standard format, using real data to solve actual engineering problems, preparing students for their future careers.
