Analysis, Synthesis and Design of Chemical Processes / Edition 4

The leading integrated chemical process design guide: Now with extensive new coverage and more process designs

More than ever, effective design is the focal point of sound chemical engineering. Analysis, Synthesis, and Design of Chemical Processes, Fourth Edition, presents design as a creative process that integrates both the big picture and the small details–and knows which to stress when, and why. Realistic from start to finish, this updated edition moves readers beyond classroom exercises into open-ended, real-world process problem solving. The authors introduce integrated techniques for every facet of the discipline, from finance to operations, new plant design to existing process optimization.

This fourth edition adds new chapters introducing dynamic process simulation; advanced concepts in steady-state simulation; extensive coverage of thermodynamics packages for modeling processes containing electrolyte solutions and solids; and a concise introduction to logic control. “What You Have Learned” summaries have been added to each chapter, and the text’s organization has been refined for greater clarity.

Coverage Includes

  • Conceptualization and analysis: flow diagrams, batch processing, tracing, process conditions, and product design strategies
  • Economic analysis: capital and manufacturing costs, financial calculations, and profitability analysis
  • Synthesis and optimization: principles, PFD synthesis, simulation techniques, top-down and bottom-up optimization, pinch technology, and software-based control
  • Advanced steady-state simulation: goals, models, solution strategies, and sensitivity and optimization studies
  • Dynamic simulation: goals, development, solution methods, algorithms, and solvers
  • Performance analysis: I/O models, tools, performance curves, reactor performance, troubleshooting, and “debottlenecking”
  • Societal impact: ethics, professionalism, health, safety, environmental issues, and green engineering
  • Interpersonal and communication skills: improving teamwork and group effectiveness

This title draws on more than fifty years of innovative chemical engineering instruction at West Virginia University and the University of Nevada, Reno. It includes suggested curricula for single-semester and year-long design courses, case studies and practical design projects, current equipment cost data, and extensive preliminary design information that can be used as the starting point for more detailed analyses.

This book represents the culmination of many years of teaching experience in the senior design course at West Virginia University (WVU) and University of Nevada, Reno. Although the program at WVU has evolved over the last thirty years and is still evolving, it is fair to say that the current program has gelled over the last twenty years as a concerted effort by the authors to integrate "design" throughout the undergraduate curriculum in chemical engineering.

We view design as the focal point of chemical engineering practice. Far more than the development of a set of specifications for a new chemical plant, design is the creative activity through which engineers continuously improve the operations of facilities to create products that enhance the quality of life. Whether developing the grass-roots plant, proposing and guiding process modifications, or troubleshooting and implementing operational strategies for existing equipment, engineering design requires a broad spectrum of knowledge and intellectual skills to be able to analyze the big picture and the minute details and, most important, to know when to concentrate on each.

Our vehicle for helping students develop and hone their design skills is process design rather than plant design, covering synthesis of the entire chemical process through topics relating to the preliminary sizing of equipment, flowsheet optimization, economic evaluation of projects, and the operation of chemical processes. The purpose of this text is to assist chemical engineering students in making the transition from solving well-posed problems in a specific subject to integrating all the knowledge that they have gained in their undergraduate educationand applying this information to solving open-ended process problems. Many of the "nuts and bolts" issues regarding plant design (for example, what schedule pipe to use for a given stream or what corrosion allowance to use for a vessel in a certain service) are not covered. Although such issues are clearly important to the practicing engineer, several excellent handbooks and textbooks are available to address such problems, and these are cited in the text where applicable.

In the third edition, we have rearranged some of the material from previous editions, we have added a new chapter on Batch Processing and a section on Optimization of Batch Processes, and have supplied new problems for all of the quantitative chapters. We continue to emphasize the importance of understanding, analyzing, and synthesizing chemical processes and process flow diagrams. To this end, we have expanded Appendix B to include an additional seven preliminary designs of chemical processes. The CAPCOST program for preliminary evaluation of fixed capital investment and profitability analysis has been expanded to include more equipment. Finally, the chapters on outcomes assessment, written and oral communications and a written report case study have been moved to the CD accompanying the text.

The arrangement of chapters into the six sections of the book is similar to that adopted in the Second Edition. These are sections are:
• Section 1-Conceptualization and Analysis of Chemical Processes
• Section 2-Engineering Economic Analysis of Chemical Processes
• Section 3-Synthesis and Optimization of Chemical Processes
• Section 4-Analysis of Process Performance
• Section 5-The Impact of Chemical Engineering Design on Society
• Section 6- Interpersonal and Communication Skills

In Section 1, the student is introduced first to the principal diagrams that are used to describe a chemical process. Next, the evolution and generation of different process configurations are covered. Key concepts used in evaluating batch processes are included in the new Chapter 3, and the chapter on product design has been moved to Chapter 4. Finally, the analysis of existing processes is covered. In Section 2, the information needed to assess the economic feasibility of a process is covered. This includes the estimation of fixed capital investment and manufacturing costs, the concepts of the time value of money and financial calculations, and finally the combination of these costs into profitability measures for the process. Section 3 covers the synthesis of a chemical process. The minimum information required to simulate a process is given, as are the basics of using a process simulator. The choice of the appropriate thermodynamic model to use in a simulation is covered and the choice of separation operations is covered. In addition, process optimization (including an introduction to optimization of batch processes) and heat integration techniques are covered in this section. In Section 4, the analysis of the performance of existing processes and equipment is covered. The material in Section 4 is substantially different from that found in most textbooks. We consider equipment that is already built and operating and analyze how the operation can be changed, how an operating problem may be solved, and how to analyze what has occurred in the process to cause an observed change. In Section 5, the impact of chemical engineering design on society is covered. The role of the professional engineer in society is addressed. Separate chapters addressing ethics and professionalism, health, safety, and the environment, and green engineering are included. Finally, in Section 6, the interpersonal skills required by the engineer to function as part of a team and to communicate both orally and written are covered (on the CD). An entire chapter (on the CD) is devoted to addressing some of the common mistakes that students make in written reports.

Finally, two appendices are included. Appendix A gives a series of cost charts for equipment. This information is embedded in the CAPCOST program for evaluating fixed capital investments and process economics. Appendix B gives the preliminary design information for eleven chemical processes: dimethyl ether, ethylbenzene, styrene, drying oil, maleic anhydride, ethylene oxide, formalin, batch manufacture of amino acids, acrylic acid, acetone, and heptenes production. This information is used in many of the end-of-chapter problems in the book. These processes can also be used as the starting point for more detailed analyses, for example, optimization studies. Other projects are included on the CD accompanying this book. The reader (faculty and students) is also referred to our Web site at, where a variety of design projects for sophomore- through senior-level chemical engineering courses is provided. There is also a link to another Web site that contains environmentally related design projects.

For a one-semester design course, we recommend including the following core:
• Section 1-Chapters 1 through 6
• Section 3-Chapters 11, 12, and 13
• Section 5-Chapters 23 and 24

For programs in which engineering economics is not a prerequisite to the design course, Section 2 (Chapters 7-10) should also be included. If students have previously covered engineering economics, Chapters 14 and 15 covering optimization and pinch technology could be substituted.

For the second term of a two-term sequence, we recommend Chapters 16 through 20 (and Chapters 14 and 15 if not included in the first design course) plus design projects. If time permits, we also recommend Chapter 21 (Regulating Process Conditions) and Chapter 22 (Process Troubleshooting) as these tend to solidify as well as extend the concepts of Chapters 16 through 20, that is, what an entry-level process engineer will encounter in the first few years of employment at a chemical process facility. For an environmental emphasis, Chapter 25 could be substituted for Chapters 21 and 22; however, it is recommended that supplementary material be included.

We have found that the most effective way both to enhance and to examine student progress is through oral presentations in addition to the submission of written reports. During these oral presentations, individual students or a student group defend their results to a faculty panel, much like a graduate student defends a thesis or dissertation.
