Guidelines for Inherently Safer Chemical Processes
Wiley-AIChE (Verlag)
978-1-119-52916-3 (ISBN)
The new edition builds on the same philosophy as the first two editions, but further clarifies the concept with recent research, practitioner observations, added examples and industry methods, and discussions of security and regulatory issues. Inherently Safer Chemical Processes presents a holistic approach to making the development, manufacture, and use of chemicals safer. The main goal of this book is to help guide the future state of chemical process evolution by illustrating and emphasizing the merits of integrating inherently safer design process-related research, development, and design into a comprehensive process that balances safety, capital, and environmental concerns throughout the life cycle of the process.
It discusses strategies of how to: substitute more benign chemicals at the development stage, minimize risk in the transportation of chemicals, use safer processing methods at the manufacturing stage, and decommission a manufacturing plant so that what is left behind does not endanger the public or environment.
The Center for Chemical Process Safety (CCPS) was founded in 1985 to develop technology and management practices that mitigate or eliminate process safety incidents in the chemical and petrochemical industries. Since that time, CCPS has published more than 100 books and held dozens of international conferences, each representing the most advanced thinking in process safety. CCPS is supported by the contributions and voluntary participation of more than 200 companies globally. CCPS is also the world's largest provider of undergraduate engineering curriculum materials through its SAChE program, with more than 160 universities participating from around the world.
