Chemical processes provide a diverse array of valuable products and materials used in applications ranging from health care to transportation and food processing. Yet these same chemical processes that provide products and materials essential to modern economies, also generate substantial quantities of wastes and emissions. Green Chemistry is the utilization of a set of principles that reduces or eliminate the use or generation of hazardous substances in design. Due to extravagant costs needed to managing these wastes, tens of billions of dollars a year, there is a need to propose a way to create less waste. Emission and treatment standards continue to become more stringent, which causes these costs to continue to escalate.
Green Chemistry and Engineering describes both the science (theory) and engineering (application) principles of Green Chemistry that lead to the generation of less waste. It explores the use of milder manufacturing conditions resulting from the use of smarter organic synthetic techniques and the maintenance of atom efficiency that can temper the effects of chemical processes. By implementing these techniques means less waste, which will save industry millions of dollars over time.
- Chemical processes that provide products and materials essential to modern economies generate substantial quantities of wastes and emissions, this new book describes both the science (theory) and engineering (application) principles of Green Chemistry that lead to the generation of less waste
- This book contains expert advise from scientists around the world, encompassing developments in the field since 2000
- Aids manufacturers, scientists, managers, and engineers on how to implement ongoing changes in a vast developing field that is important to the environment and our lives
Environmental engineers, chemical engineers, industrial engineers, scientists, biochemists, facility managers, advanced undergraduate and post-graduate, specialized courses in Chemistry, Chemical technology, Chemical Engineering and Pharmaceutical sciences Environment technology. Elective in Biocatalysis/Biotransformation
CHAPTER 1 – Introduction
What is Green Chemistry? and Why Green? What has been happening over the past 60 years in the area of chemistry and chemical technology, with reference to waste, pollution, effluent and other environmental issues, which are caused by chemical manufacturing, will be listed. The advantages of this approach will be outlined Concept of measuring “greenness”. What is responsible care?
CHAPTER 2 – Novel Synthetic techniques
Examples of organic reactions which shows innovation in the reduction of raw material/solvent usage, milder operating conditions, generates less wasteful side products etc.
CHAPTER 3 – Use of catalysts towards Green Chemistry
Examples of reactions that use Heterogeneous or homogeneous catalysts leading to ‘Green’ scenario. By using these catalyst either the reaction is made milder, efficiency is improved or the amount of side product formed is decreased etc.
CHAPTER 4 – Biocatalysis and Green chemistry
Examples of biotransformations leading to ‘Green’ scenario. There are several examples where biocatalysis simplifies the reaction, telescopes multiple steps into one and makes it environmentally clean and friendly. Even reactions which can not be performed with chemical synthesis can be carried out with ease using microbes.
CHAPTER 5 – New reagents and solvents
Use of new reagents and solvents which are benign, environmentally friendly and do not contribute towards voc.
CHAPTER 6 – Process and Operation
Process intensification, better hardware design, better unit operation design, better flow sheet etc. It will also cover use of membranes and other novel down stream processing techniques.
CHAPTER 7 – Energy and Renewable resources
Alternate energy sources discussed. Hydrocarbon fuel is a non-renewable source of energy. Research using alternate energy sources is being pursued seriously in many research labs world over. Also apart from simple heating ultra sound, IR are also being considered as sources for initiating reactions. Use of renewable raw material includes ethanol, biodiesel etc.
CHAPTER 8 – Inherent safety
Processes that are milder, use less toxic solvents, do not product dangerous intermediate, do not produce recalcitrant waste or side products chemicals etc. are termed as inherently safe. Such a philosophy could prevent another Bhopal.
CHAPTER 9 – Industrial Examples/Case studies
Industrial examples of processes where ‘Green’ has been implemented or practiced are discussed in this chapter.
CHAPTER 10 – Future trends
Frontier research. A glimpse into the future will be outlined and the direction the future research will take will be predicted.
