What is Chemical engineering?

1-Chemical engineering is the branch of engineering that deals with the application of physical science (chemistry and physics), and life sciences (biology, microbiology and biochemistry) with mathematics, to the process of converting raw materials or chemicals into more useful or valuable forms. In addition to producing useful materials, modern chemical engineering is also concerned with pioneering valuable new materials and techniques - such as nanotechnology, fuel cells and biomedical engineering.

2-Chemical engineering is the application of science, in particular chemistry and fluid physics, along with mathematics and economics to the process of converting raw materials or chemicals into more useful or valuable forms.

3-Chemical engineering is the field with sufficient economical control of chemical process,design of chemical reactants and processing plant development of food, waste and pollutants.
