Process design is the focal point of chemical engineering practice: the creative activity through which engineers continuously improve facility operations to create products that enhance life. Effective chemical engineering design requires students to integrate a broad spectrum of knowledge and intellectual skills, so they can analyze both the big picture and minute details - and know when to focus on each. Through three previous editions, this book has established itself as the leading resource for students seeking to apply what they've learned in real-world, open-ended process problems. The authors help students hone and synthesize their design skills through expert coverage of preliminary equipment sizing, flowsheet optimization, economic evaluation, operation and control, simulation, and other key topics. This new Fourth Edition is extensively updated to reflect new technologies, simulation techniques, and process control strategies, and to include new pedagogical features including concise summaries and end-of-chapter lists of skills and knowledge. New coverage includes four additional case studies, plus: A new chapter on steady state simulators, addressing key capabilities found in tools such as Chemcad, Aspen Plus, Hysys, and Pro/II A new chapter on dynamic simulators: the first of its kind in any chemical process design book Expanded coverage of process regulation and control at both low and high levels, including Model Predictive Control
