Design and Control of Distillation Systems for Separating Azeotropes


Book Description

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.

Distillation Design and Control Using Aspen Simulation


Book Description

A timely treatment of distillationcombining steady-state designand dynamic controllability As the world continues to seek new sources of energy, the distillation process remains one of the most important separation methods in the chemical, petroleum, and energy industries. And as new renewable sources of energy and chemical feedstocks become more universally utilized, the issues of distillation design and control will remain vital to a future sustainable lifestyle. Distillation Design and Control Using Aspen Simulation introduces the current status and future implications of this vital technology from the dual perspectives of steady-state design and dynamics. Where traditional design texts have focused mainly on the steady-state economic aspects of distillation design, William Luyben also addresses such issues as dynamic performance in the face of disturbances. Utilizing the commercial simulators Aspen Plus and Aspen Dynamics, the text guides future and practicing chemical engineers first in the development of optimal steady-state designs of distillation systems, and then in the development of effective control structures. Unique features of the text include: * In-depth coverage of the dynamics of column design to help develop effective control structures for distillation columns * Development of rigorous simulations of single distillation columns and sequences of columns * Coverage of design and control of petroleum fractionators Encompassing nearly four decades of research and practical developments in this dynamic field, the text represents an important reference for both students and experienced engineers faced with distillation problems.




Distillation Theory and its Application to Optimal Design of Separation Units


Book Description

Originally published in 2004, Distillation Theory and Its Application to Optimal Design of Separation Units presents a clear, multidimensional geometric representation of distillation theory that is valid for all distillation column types, splits, and mixtures. This representation answers such fundamental questions as: what are the feasible separation products for a given mixture? What minimum power is required to separate a given mixture? What minimum number of trays is necessary to separate a given mixture at a fixed power input? This book is intended for students and specialists in the design and operation of separation units in the chemical, pharmaceutical, food, wood, petrochemical, oil-refining, and natural gas industries and for software designers.




Separation and Purification Technologies in Biorefineries


Book Description

Separation and purification processes play a critical role in biorefineries and their optimal selection, design and operation to maximise product yields and improve overall process efficiency. Separations and purifications are necessary for upstream processes as well as in maximising and improving product recovery in downstream processes. These processes account for a significant fraction of the total capital and operating costs and also are highly energy intensive. Consequently, a better understanding of separation and purification processes, current and possible alternative and novel advanced methods is essential for achieving the overall techno-economic feasibility and commercial success of sustainable biorefineries. This book presents a comprehensive overview focused specifically on the present state, future challenges and opportunities for separation and purification methods and technologies in biorefineries. Topics covered include: Equilibrium Separations: Distillation, liquid-liquid extraction and supercritical fluid extraction. Affinity-Based Separations: Adsorption, ion exchange, and simulated moving bed technologies. Membrane Based Separations: Microfiltration, ultrafiltration and diafiltration, nanofiltration, membrane pervaporation, and membrane distillation. Solid-liquid Separations: Conventional filtration and solid-liquid extraction. Hybrid/Integrated Reaction-Separation Systems: Membrane bioreactors, extractive fermentation, reactive distillation and reactive absorption. For each of these processes, the fundamental principles and design aspects are presented, followed by a detailed discussion and specific examples of applications in biorefineries. Each chapter also considers the market needs, industrial challenges, future opportunities, and economic importance of the separation and purification methods. The book concludes with a series of detailed case studies including cellulosic bioethanol production, extraction of algae oil from microalgae, and production of biopolymers. Separation and Purification Technologies in Biorefineries is an essential resource for scientists and engineers, as well as researchers and academics working in the broader conventional and emerging bio-based products industry, including biomaterials, biochemicals, biofuels and bioenergy.
