Chemical engineering applies physical and life sciences together with engineering and economics principles to produce, transform, transport, and properly use chemicals, materials, and energy. It essentially deals with the engineering of chemicals, energy, and the processes that create and/or convert them. Chemical Engineering differs from chemistry in its emphasis on commercial applications of chemical reactions and separations and techniques for designing, operating, and controlling processes.  Modern chemical engineering also concerned with creating and processing materials and related techniques related fields such as nanotechnology, energy storage devices, and pharmaceutical engineering. The Chemical Engineering B.Sc. program at Khalifa University educates engineers to design, develop, and operate chemical processes by which chemicals, petroleum products, food, pharmaceuticals, and consumer goods can be produced economically and safely.
