Available in PDF, EPUB and Kindle. Book excerpt: Researchers share their pioneering graphical method for designing almost any distillation structure Developed by the authors in collaboration with other researchers at the Centre of Material and Process Synthesis, column profile maps (CPMs) enable chemical engineers to design almost any distillation structure using novel graphical techniques. The CPM method offers tremendous advantages over other design methods because it is generalized and not constrained to a particular piece of equipment. Understanding Distillation Using Column Profile Maps enables readers to understand, analyze, and design distillation structures to solve common distillation problems, including distillation by simple columns, side rectifiers and strippers, multiple feed columns, and fully thermally coupled columns. In addition, the book presents advanced topics such as reactive distillation, membrane permeation, and validation of thermodynamic models. For all these processes, the authors set forth easy-to-follow design techniques, solution strategies, and insights gained using CPMs. This book offers everything needed to fully understand and use CPMs as a design tool: Figures help readers understand how to use CPMs as design and optimization tools Examples clearly illustrate how to solve specific problems using CPMs Tutorials allow readers to explore key concepts through experimentation Design and Optimization of Distillation Systems software package, developed for this book, enables readers to reproduce the examples in the book, follow the tutorials, and begin designing their own distillation systems With its many examples and step-by-step tutorials, Understanding Distillation Using Column Profile Maps is recommended for students in chemical engineering in advanced undergraduate and graduate courses. The book also provides new practical techniques that can be immediately applied by chemical engineering professionals in industry.

Available in PDF, EPUB and Kindle. Book excerpt: The development of an inferential soft sensor for a pilot-plant distillation column separating an ethanol-water mixture using neural network (NN) models has been investigated in this work. Inferential sensors are increasingly used in the process industries to infer the value of the main quality variable while utilizing much easier to measure secondary variables of the process. The lags between the input variables and the output variables vary due to changes in operating conditions. Previous studies have introduced different methods to estimate lags for input and output variables, but all of them have assumed these lags to be constant regardless of the changes in the operating conditions. In this work, an inferential sensor that can predict the composition of ethanol at the top product using time lags for the input variables and varied first-order time constant lags with the output variable has been developed. The developed inferential sensor is based on a neural network (NN) model. Principal Component Analysis (PCA) and Projection to Latent Structures (PLS) methods are used in this work to remove the outliers from the input variables set and to determine the most correlated values of the input variables and their lags with the output variable Xa (ethanol composition of distillate product) respectively. The model adaptively selects the correct first-order time constant lags of an output variable according to the instantaneous operating condition (the composition of ethanol is increased or decreased) and assigns a best value for each case. The experimental data resulting from the operation of pilot-scale batch distillation column of ethanol-water system has been used to build these NN models first and then to validate their performance. The proposed NN model structure with time lags for input variables and varied first-order time constant lags for output variable gave higher accuracy compared with the NN model without any time lag for input and output variables. This new developed NN based soft sensor has been used in an inferential proportional-integral (PI) control scheme to control the ethanol composition of the distillate. The initial inferential control results of using one tuning parameter set during the whole operation showed imperfect control results. So, using updated tuning parameter sets (gain scheduling/adaptive tuning) within this inferential PI control scheme based on the ethanol mole fraction region is necessary to improve the control performance. The results of this new developed PI control scheme showed a good control performance compared with the initial control results of this inferential controller using one set of tuning parameters. Then, this new developed NN based soft sensor has also been used in an advanced control scheme (model predictive control or MPC scheme). Two DeltaV MPC control schemes (MPC11 and MPC22) have been developed in this work. The control results of DeltaV MPC22 control scheme showed better control performance compared with other control schemes (inferential PI and MPC11 control schemes). This is due to the capability of this control scheme (MPC22) to handle the interactions between different variables (multivariable effect) especially for the distillation process. Also, it provided a faster response with very small undershoot or overshoot

Available in PDF, EPUB and Kindle. Book excerpt: A distillation column is both multivariable and nonlinear - and it consumes immense quantities of energy. Yet, despite the desigh challenges it presents, it is still the most popular unit operation for refining in industrial plants today. Much has been published on the subject of distillation column design, but much remains to be explained. That is why this book is unique. In a departure from the more traditional empirical and theoretical approaches, it introduced the reader to the practical realm, by presenting quantitative design techniques that have been demonstrated to be useful and valid over the course of hundreds of actual applications. The book is divided into three main parts. Part I, an introduction, presents an industrial perspective of control objectives. It discusses briefly the relationship between column design features and column controllability. It thus provides a short refresher course for chemical engineers and background for those trained in other branches of engineering. Part II, Concepts and Configurations, discusses column overhead and base arrangements, typical control schemes, and some hardware considerations. Part III is dedicated to quantitative design. Mathematical models are presented for pressure and differential pressure controls, liquid level control, and composition control of binary distillation. Emphasis on topics of primary interest to the control engineer Essentially nonmathematical treatment Ideal for those involved in troubleshooting existing columns as well to design engineers

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.
