Chemical engineering
Chemical Engineering
Chemical engineering (pronunciation: /ˈkɛmɪkəl ɛndʒɪˈnɪərɪŋ/) is a branch of engineering that uses principles of chemistry, physics, mathematics, biology, and economics to efficiently use, produce, design, transport and transform energy and materials. The work of chemical engineers can range from the utilization of nanotechnology and nanomaterials in the laboratory to large-scale industrial processes that convert chemicals, raw materials, living cells, microorganisms, and energy into useful forms and products.
Etymology
The term "chemical engineering" is believed to have been first used by George E. Davis in a lecture series in 1887. The term "chemical engineer," however, was not used until 1916 when it was included in the title of a book by Arthur D. Little.
