Thermal Safety of Chemical Processes adopts a unique systematic how-to-do approach—each chapter begins with a case history illustrating the topic and presenting the lessons learned from the incident. It analyzes a goldmine of numerous examples stemming from industrial practice, additionally providing a series of problems or case studies at the end of each chapter.
Divided into three distinct sections, Part One looks at the general aspects of thermal process safety, while Part Two deals with mastering exothermal reactions. The final section discusses the avoidance of secondary reactions, including heat accumulation and thermal confinement.
