The effort in this book is directed towards the understanding of the overall view of the chemical engineering subjects. In-fact, the Chemical Engineering professionals do not only confine themselves in a specific field of work but their work is diversified in different fields of production, purification, water treatment, waste management, food production, computation,Medical, Energy, Environmental, Biochemical, Electronics etc. based on the concept of Unit Processes and Unit Operations; Designing of equipments; Flowsheet representation. Interactive relation between Chemical Engineering and other engineering disciplines have been thoroughly discussed in this book with a overview of Traditional vis-a-vis modern Chemical Engineering approaches. Components of Chemical Engineering subjects are discussed in detail to illustrate an overall view of the discipline.With a bright enumeration of the role of a Chemical Engineer with its History,Personalities and greatest achievements, the book is describes Paradigm shifts in Chemical Engineering to the Future prospects of Chemical Engineering discipline.
