Description

Principles of Chemical Engineering Processes: Material and Energy Balances introduces the basic principles and calculation techniques used in the field of chemical engineering, providing a solid understanding of the fundamentals of the application of material and energy balances. Packed with illustrative examples and case studies, this book:

  • Discusses problems in material and energy balances related to chemical reactors
  • Explains the concepts of dimensions, units, psychrometry, steam properties, and conservation of mass and energy
  • Demonstrates how MATLAB® and Simulink® can be used to solve complicated problems of material and energy balances
  • Shows how to solve steady-state and transient mass and energy balance problems involving multiple-unit processes and recycle, bypass, and purge streams
  • Develops quantitative problem-solving skills, specifically the ability to think quantitatively (including numbers and units), the ability to translate words into diagrams and mathematical expressions, the ability to use common sense to interpret vague and ambiguous language in problem statements, and the ability to make judicious use of approximations and reasonable assumptions to simplify problems

This Second Edition has been updated based upon feedback from professors and students. It features a new chapter related to single- and multiphase systems and contains additional solved examples and homework problems. Educational software, downloadable exercises, and a solutions manual are available with qualifying course adoption.

Reviews

"Throughout this book the underlying theory of material and energy balances is clearly and succinctly presented by the authors before extensive worked examples are used to demonstrate its application to a range of process problems including multiple units systems with and without reactions occurring. This would allow the book to be used as a main text for an entry level undergraduate course in fundamental chemical process principles or used by practising engineers for both reference and self-study. The authors have clearly given a lot of thought on how to present the material in a user-friendly way to maximize learning and facilitate understanding of core chemical engineering principles."

—Dr. Diane Rossiter, Retired Senior University Teacher, The University of Sheffield, UK

"The materials are well organized in a step-by-step style and engage readers greatly. In addition to helping chemical engineering students to directly select and master the topics of their interest, the book may even help non-chemical engineering students to grasp the most important basics of chemical engineering. A quick understanding of basic chemical engineering concepts is delivered briefly and clearly without losing accuracy and depth. The examples provided in the book are great for the readers to comprehend the concepts, calculations, and chemical unit operations."

—Zhaolin (Forest) Wang, University of Ontario Institute of Technology, Canada

"The contents are excellent. Starting with detailed analysis of a single unit without chemical reaction and then gradually moving into multiple units with chemical reactions is a very good approach to train chemical engineering students."

—Professor Iqbal M Mujtaba, University of Bradford, UK
