Chemical engineering is the branch of engineering that deals with physical science (e.g., chemistry and physics), and life sciences (e.g., biology, microbiology and biochemistry) with mathematics and economics, to the process of converting raw materials or chemicals into more useful or valuable forms. In addition, modern chemical engineers are also concerned with pioneering valuable new materials and related techniques – which are often essential to related fields such as nanotechnology, fuel cells and biomedical engineering. Within chemical engineering, two broad subgroups include 1) design, manufacture, and operation of plants and machinery in industrial chemical and related processes ("chemical process engineers"); and 2) development of new or adapted substances for products ranging from foods and beverages to cosmetics to cleaners to pharmaceutical ingredients, among many other products ("chemical product engineers").

Chemical engineers "develop economic ways of using materials and energy" as opposed to chemists who are more interested in the basic composition of materials and synthesizing products from such. Chemical engineers use chemistry and engineering to turn raw materials into usable products, such as medicine, petrochemicals and plastics. They are also involved in waste management and research. Both applied and research facets make extensive use of computers.
A chemical engineer may be involved in industry or university research where he or she is tasked in designing and performing experiments to create new and better ways of production, controlling pollution, conserving resources and making these processes safer. He/she may be involved in designing and constructing plants as a project engineer. In this field, the chemical engineer uses his/her knowledge in selecting plant equipment and the optimum method of production to minimize costs and increase profitability. After its construction, he/she may help in upgrading its equipment. He/she may also be involved in its daily operations. View More
