Chemical engineering
Chemical engineering is[ the branch of engineering that deals with physical science] (e.g., chemistry and physics), and lifesciences (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, modernchemical 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 biomedicalengineering.[1] Within chemical engineering, two broad subgroups include 1) design, manufacture, and operation of plants and machinery in industrial chemical and related processes ("chemical processengineers"); 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 ("chemicalproduct engineers").
Chemical engineering emerged upon [the development of unit operations, a fundamental concept of the discipline]. Most authors agree that Davis invented [unit operations if notsubstantially developed it].[7] He gave[ a series of lectures on unit operations at the Manchester Technical School (University of Manchester today) in 1887, considered to be one of the earliest such aboutchemical engineering].[8] Three years before Davis' lectures, Henry Edward Armstrong taught a degree course in chemical engineering at the City and Guilds of London Institute. Armstrong's course "failedsimply because its graduates ... were not especially attractive to employers." Employers of the time would have rather hired [chemists and mechanical engineers.[4] Courses in chemical engineeringoffered by Massachusetts Institute of Technology (MIT) in the United States, Owen's College in Manchester, England and University College London suffered under similar circumstances.
