Easy-to-implement solutions that don't require complex mathematics Without resorting to complicated concepts,Troubleshooting Process Plant Control gives you the skills needed to solve typical problems in process control. It's filled with real-life examples of problems that commonly arise in process control alongside commonsense solutions. Moreover, the text is exceptionally easy to understand. While there are many new control concepts presented, they are all solidly based on decades-old technical concepts. Troubleshooting Process Plant Control focuses on problem solving in the petroleum and refinery industries. It emphasizes well-established process engineering principles that enable engineers and operators to switch from manual control loops to automatic control. Among the chapters presented are: Pressure control in multicomponent systems—refrigeration and distillation Sizing control valves—oversizing and undersizing consequences Centrifugal compressor surge and motor overamping Function of a process control engineer—practical ideas—the job in a process plant Alarms and trips—design and field testing—promoting safety in plant operations HAZOP and P&ID reviews Author Norman Lieberman is well known throughout the process industry for his ability to troubleshoot complex problems and teach others how to do it as well. Thousands of engineers and operators have advanced their skills by reading his books, watching his videotapes, and attending his popular seminar "Troubleshooting Process Operations." With its straightforward explanations, clear examples, and easy-to-implement solutions, this book is ideal for all plant panel board operators and process engineers.
