Control and automation in chemical engineering

This book shows a solved problems collection with the aim of covering the knowledge requirements of the students of Chemical Engineering. The book begins with feedback systems, after having seen the block diagrams, until the study of stability using the frequency response. Some problems about control systems that are not based on feedback systems, always applied on Chemical Processes (Chapters 1, 2 and 3). The second part of the book is focused on applying in a practical way the concepts of Automation and Control. The chapter 4 solves discrete systems using pneumatic elements and programmable logic devices (PLCs). Finally, chapter 5 deals with the control of continuous processes using a PLC.
