The main role of chemical engineers is to design and troubleshoot processes for the production of chemicals, fuels, foods, pharmaceuticals, and biologicals, to name just a few. They are most often employed by large-scale manufacturing plants to maximize productivity and product quality while minimizing costs. The book presents the key areas of chemical engineering, their mathematical foundations, and corresponding modeling techniques. This book also examines the newest technologies for sustainable development in chemical engineering, through careful analysis of the technical aspects, and discussion of the possible fields of industrial development.
