Chemical engineering is the branch of engineering dealing with the application of physical science to the process of converting raw materials or chemicals into more useful or valuable forms. In addition to producing useful materials, chemical engineering includes development of new materials and techniques i.e. nanotechnology, fuel cells and biomedical engineering. Chemical engineering is applied in a wide variety of industries and disciplines..

Engineers are constantly looking for ways to optimize the flows in industrial processes leading to improved efficiency, energy savings, a better finished product, and more environmentally friendly methods.
