The new edition of this book greatly updates and expands the previous edition. It boasts new chapters on the divided wall column and carbon dioxide capture from stack gas, revises the design and control of distillation systems, and explains the use of dynamic simulation to study safety issues in the event of operating failures. Using Aspen Plus to develop rigorous simulations of single distillation columns and sequences of columns, the book considers the economics of capital investment and energy costs to create an optimal system for separation methods in the chemical and petroleum industries.

After an overview of the fundamentals, limitations, and scope of reactive distillation, this book uses rigorous models for steady-state design and dynamic analysis of different types of reactive distillation columns and quantitatively compares the economics of reactive distillation columns with conventional multi-unit processes. It goes beyond traditional steady-state design that primarily considers the capital investment and energy costs when analyzing the control structure and the dynamic robustness of disturbances, and discusses how to maximize the economic and environmental benefits of reactive distillation technology.

Chemical Reactor Design and Control uses process simulators like Matlab®, Aspen Plus, and Aspen Dynamics to study the design of chemical reactors and their dynamic control. There are numerous books that focus on steady-state reactor design. There are no books that consider practical control systems for real industrial reactors. This unique reference addresses the simultaneous design and control of chemical reactors. After a discussion of reactor basics, it: Covers three types of classical reactors: continuous stirred tank (CSTR), batch, and tubular plug flow Emphasizes temperature control and the critical impact of steady-state design on the dynamics and stability of reactors Covers chemical reactors and control problems in a plantwide environment Incorporates numerous tables and shows step-by-step calculations with equations Discusses how to use process simulators to address diverse issues and types of operations This is a practical reference for chemical engineering professionals in the process industries, professionals who work with chemical reactors, and students in undergraduate and graduate reactor design, process control, and plant design courses.

Distillation has historically been the main method forseparating mixtures in the chemical process industry. However,despite the flexibility and widespread use of distillationprocesses, they still remain extremely energy inefficient.Increased optimization and novel distillation concepts can deliversubstantial benefits, not just in terms of significantly lowerenergy use, but also in reducing capital investment and improvingeco-efficiency. While likely to remain the separation technology ofchoice for the next few decades, there is no doubt thatdistillation technologies need to make radical changes in order tomeet the demands of the energy-conscious society. Advanced Distillation Technologies: Design, Control andApplications gives a deep and broad insight into integratedseparations using non-conventional arrangements, including bothcurrent and upcoming process intensification technologies. It includes: Key concepts in distillation technology Principles of design, control, sizing and economics ofdistillation Dividing-wall column (DWC) – design, configurations,optimal operation and energy efficient and advanced control DWC applications in ternary separations, azeotropic, extractiveand reactive distillation Heat integrated distillation column (HIDiC) – design,equipment and configurations Heat-pump assisted applications (MVR, TVR, AHP, CHRP, TAHP andothers) Cyclic distillation technology – concepts, modelingapproach, 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, thisis a unique resource that tackles the most advanced distillationtechnologies – all the way from the conceptual design topractical implementation.

Solving the model structure with a large equation set becomes a challenging task due to the involvement of several complex processes in an industrial plant. To overcome these challenges, various process flow sheet simulators are used. This book, now in its second edition, continues to discuss the simulation, optimization, dynamics and closed-loop control of a wide variety of chemical processes using the most popular commercial flow sheet simulator ASPENTM. A large variety of chemical units including flash drum, continuous stirred tank reactor, plug flow reactor, petroleum refining column, heat exchanger, absorption tower, reactive distillation, distillation train, and monomer production unit are thoroughly explained. The book acquaints the students with the simulation of large chemical plants with several single process units. With the addition of the new sections, additional information and plenty of illustrations and exercises, this text should prove extremely useful for the students. Designed for the students of chemical engineering at the senior under-graduate and postgraduate level, this book will also be helpful to research scientists and practising engineers as a handy guide to simulation of chemical processes. NEW TO THIS EDITION : Section 1.3 on Stepwise Aspen Plus Simulation of Flash Drums is thoroughly updated (Chapter 1) Section 3.2 on Aspen Plus Simulation of the Binary Distillation Columns is updated, a new section on Simulation of a Reactive Distillation Column is added (Section 3.6), and a new topic on Column Sizing is introduced (Chapter 3) A new section on Aspen Simulation of a Petlyuk Column with Streams Recycling is included (Chapter 4)

An azeotrope is a mixture of two or more compounds that cannot be separated or changed by simple distillation. This book addresses an important issue in the energy crisis: the distillation of azeotropes to improve the processing of biofuels. It describes azeotropic systems in a comprehensive, readable form, with updates on recent developments in vapor-liquid and liquid-liquid-vapor equilibrium, simulation tools, and specific examples covering the major processing options available. The text also presents methods for achieving optimum economic design and control structures, and demonstrates trade-offs between energy savings and controllability (product quality variability).

A pre-cut column from the Palm Oil Fractionation Plant is one approach to the distillation of fatty acids. This research aim to develop dynamic Pre Cut Column model using ASPEN and incorporate control system into distillation column model. The scope of this study is to learn how to use dynamic simulators by simulating Pre Cut Column in steady-state condition and moving to a dynamic simulation, then applying PID (proportional-integral-derivative) control system as an effective control system for continuous processes. For designing the precut column, the method that must be concerned are specifying chemical components and physical properties, specifying stream properties and specifying equipment parameters before running the simulation. PID controllers are the controller of choice for controlling the precut column because PID system is a balancing act with all terms interacting. Integral feedback Element (I) is added to the proportional element to provide a means for eliminating a changing offset in a non linear system and to slow down the reaction to allow for the time delays in the system. Derivative feedback element (D) is added to provide a means of reducing sudden changes in the output and will provide a faster response to step functions and transients. The result was in steady state simulation of precut column and the parameters of controllers were identified from dynamic responses. Dynamic simulation has become increasingly important as processes become more complex and are designed and operated closer to constraints.-Author.
