Additional comments on using the book

This book has 118 separate numerical examples spread over Chapters 1-4 and 6-9. The numerical examples are not in finer print. Chapter 5 has sometimes employed numerical calculations to illustrate the effect of chemical reactions on separations without formal numerical examples. Chapter 10 follows this strategy as well to illustrate the amount of energy required for a particular separation. The total number of problems provided at the ends of all the chapters is 299. The specific separation process relevant for the problem is generally obvious from the introductory sentence in the problem. Further, the sequence of appearance of a problem on a given separation process reflects/follows the sequences of appearance of that separation process in the text. 

Foomotes have been employed occasionally. All references used appear at one location in alphabetical order at the end of the book. The symbols and notation employed throughout the book are consistent any local deviation has been identified. In a few locations, advanced material or additional information has been provided.
