This book was released on 2006-04-20 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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 Controlling Trace Impurities in a Dividing Wall Distillation Column written by Melissa Mary Donahue and published by . This book was released on 2018 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dividing wall distillation columns (DWCs) separate a feed mixture into three pure product streams using one column shell. Though attractive due to capital and operational savings, DWCs have yet to gain widespread industrial acceptance. One notable concern is controllability. The research within this document examines a four component feed mixture to evaluate the operational flexibility of a fixed-design DWC through experimental and simulation-based studies. A pilot DWC was successfully controlled at multiple operating points, and a dynamic model was developed to reflect the pilot dividing wall column. As a form of process intensification, DWCs have a higher risk for controller interaction making conventional PID control potentially inadequate. This work successfully used two PID temperature controllers to maintain the column at steady state, transition the column between steady states, and reject feed disturbances without controller interaction. These controller pairings were determined using conventional controller design techniques. Therefore, for this chemical system and column design, traditional approaches to distillation control are sufficient to handle the intensified nature of DWCs. Because more components are present in DWCs in larger amounts, there is concern that temperature control will no longer imply composition control. Temperature control proved successful in this study. Controlling two temperatures maintained column operation against feed disturbances. In addition, prefractionator temperature correlated well with reboiler duty for multiple feed qualities therefore serving as a promising control variable though more disturbances such as feed composition should be examined. The minimum energy controller was not tested experimentally. A steady state model with heat transfer matching the pilot data was scaled to the size of an industrial tower and used to generate a minimum energy response surface for different vapor and liquid split values. In summary, this research investigated the operational flexibility of a fixed-design DWC using a four component mixture, tested the ability of conventional distillation control design techniques to determine control structures for a DWC, and created a minimum energy operating surface that could be used to examine control structures. A technique to determine the overall heat transfer coefficients was developed, and the model closely matched experimental steady state data

Download or read book A Design Model for Dividing Wall Distillation Columns written by Bailee Jeanee Roach and published by . This book was released on 2017 with total page 744 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, the production of three high purity products from a three component mixture requires the use of two distillation columns. A Dividing Wall Column (DWC) offers an alternative to this approach. The DWC contains a vertical partition, dividing the column into two sides. The feed side separates the lowest and highest boiling products, while the product side separates the intermediate component. This configuration reduces capital costs by utilizing only one column, reboiler, and condenser and reduces the thermodynamic losses by partitioning the feed and side product. Previous theoretical studies have found that a DWC can also produce as high as 30-50 percent energy savings over a traditional multi-column scheme. Despite these advantages, validated predictive models, which will facilitate widespread adoption of the technology, are lacking. In this research, experimental results were obtained over a wide range of operating conditions using a constructed six inch diameter pilot plant data is used to develop a fully validated DWC. The pilot DWC ran several experimental tests with both an alcohol and hydrocarbon feed. Both systems were tested with an equimolar and a 10/80/10 feed composition. Internal flow rate and composition data were available that has not been published in research, allowing for a complete model validation, including heat loss and heat transfer across the dividing wall. Both Model Predictive Control and traditional PID control was tested and resulted in high quality steady state data obtained. An extensive hydraulic study was conducted for both structured and random packing. Mass transfer studies and air-water experiments were conducted to fundamentally characterize the column hydraulics. These studies included confirming the vapor split is determined by the wall location and not impacted by the pressure drop. Pressure drop and wetted area studies were performed on circular and dividing wall column structures. The dry pressure drop, irrigated pressure drop, and hold-up were compared with existing correlations. Additionally, the dividing wall wetted area was determined. A DWC model was validated with the experimental pilot data obtained as well as comparing with open literature data. With the results from the validated model, optimizations were conducted to aid in DWC design. It was shown that feed temperature is an important variable to consider in design. The vapor split did not have as much of an impact on energy savings as the liquid split. An accurate energy calculation was performed on a pilot scale column and a scale-up to industrial column diameters. The scale-up shows that the impacts from heat loss and heat transfer are not as significant in a large scale column for product purities and column liquid and vapor loads. DWC columns averaged approximately 30% energy savings. The comprehensive validated model lays the groundwork for DWC industrial expansion.

This book was released on 2014-07-14 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will present the papers delivered at the first U.S. conference devoted exclusively to global optimization and will thus provide valuable insights into the significant research on the topic that has been emerging during recent years. Held at Princeton University in May 1991, the conference brought together an interdisciplinary group of the most active developers of algorithms for global optimization in order to focus the attention of the mathematical programming community on the unsolved problems and diverse applications of this field. The main subjects addressed at the conference were advances in deterministic and stochastic methods for global optimization, parallel algorithms for global optimization problems, and applications of global optimization. Although global optimization is primarily a mathematical problem, it is relevant to several other disciplines, including computer science, applied mathematics, physical chemistry, molecular biology, statistics, physics, engineering, operations research, communication theory, and economics. Global optimization problems originate from a wide variety of mathematical models of real-world systems. Some of its applications are allocation and location problems and VLSI and data-base design problems. Originally published in 1991.
