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

Computer Aided Design of Control Systems focuses on the use of computers to analyze and design the control of various processes, as well as the development of program packages with different algorithms for digital computers. The selection first takes a look at the computer aided design of minimal order controllers, including design of interacting and noninteracting dynamic controllers of minimal order and basic algorithm. The book then discusses an accelerated Newton process to solve Riccati equation through matrix sign function; suboptimal direct digital control of a trickle-bed absorption column; and structural design of large systems employing a geometric approach. The text underscores the computer as an aid for the implementation of advanced control algorithms on physical processes and analysis of direct control algorithms and their parallel realization. Topics include hardware influences on the control, process influence, and interactive structure design of direct control systems. The book also takes a look at the optimal control of randomly sampled linear stochastic systems; computer aided design of suboptimal test signals for system identification; and computer aided design of multi-level systems with prescribed structure and control constraints. The selection is a dependable source of data for readers interested in the uses of computers.

In addition to the three main themes: chemical reactors, distillation columns, and batch processes this volume also addresses some of the new trends in dynamics and control methodology such as model based predictive control, new methods for identification of dynamic models, nonlinear control theory and the application of neural networks to identification and control. Provides a useful reference source of the major advances in the field.

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.
