Chemical and Process Engineering is the profession in which knowledge of mathematics, chemistry, physics, biology and other natural sciences gained by study, experience and practice is applied with judgment to develop economical ways of using materials and energy for the benefit of mankind.
More typically, they turn raw materials into valuable products. The necessary skills encompass all aspects of design, testing, scale-up, operation, control, and optimization. Hence this requires a detailed understanding of the various "unit operations", such as distillation, mixing, evaporation, crystallization, and biological processes that make these conversions possible.
Resting on the above foundations the Chemical and Process Engineering sprout higher and higher utilizing mass, momentum and energy transfers hand along with thermodynamics and chemical kinetics. It would be correct to say that the term Chemical in Chemical and Process Engineering refers more towards the knowledge and experience in terms of the applied sciences.
The breadth of scientific and technical knowledge inherent in this profession has caused world scientists to describe the Chemical and Process Engineer as the "Universal Engineer".
