Unit Operations of Chemical Engineering Vol-1

When I set to write this book, only a very limited number of books on unit operations were available in the Indian market. And those were all American texts. Indeed the dearth of chemical engineering books has long been felt by the students in this subcontinent. To make matter worse, high important bills still continue to deny access to such books to the Indian students. Non-existence of any chemical engineering text written by any Indian author and published in India only widened the gap between their hope and reality. However, I do not claim that the present book will fill all the ‘void’. Nor even it will. The reason is very pure and simple: the expanse of chemical engineering is enormous and its ever-expanding frontier with the introduction of newer and newer unit operations in process industries simply defies any individual’s capacity to cover the entire cross-section of this important wing of engineering.True to my commitment in the preface to the 2nd edition plus to fulfill the popular demand of the students, I have mobilized great efforts to strengthen this volume “theoretically”. And as an outcome of just that the book underwent the following revamps with the emphasis on design. Eventually the preface comes to conclusion with my hope that this enlarged and revamped edition will receive warm patronage from a wider cross-section of teachers and students of chemical engineering. Their suggestions and constructive criticism are always welcome with thanks.
