This book investigates the critical challenge of on-line fault detection and supervision within the chemical process industries. It addresses the need for robust systems that can identify and diagnose process anomalies in real-time to ensure safety, efficiency, and product quality. The work likely draws upon Stephanopoulos's expertise in chemical engineering and process systems to present methodologies for monitoring complex industrial operations.

Given the specialized nature of the topic and the author's background in chemical engineering, this book is likely aimed at a technical audience of process engineers, researchers, and advanced students. The subject matter suggests a focus on theoretical frameworks and practical implementation of fault detection systems, offering insights into maintaining operational integrity in complex chemical plants. The publication date indicates it may cover foundational principles that remain relevant, though newer technologies may have since emerged.
