Links ABCworld >> Chemical engineer Chemical engineer Chemical engineering is the application of science , in particular chemistry , along with mathematics and economics to the process of converting raw materials or chemicals into more useful or valuable forms. Chemical Engineering largely involves the design and maintenance of chemical processes for large-scale manufacture. Chemical engineers in this branch are usually employed under the title of process engineer . Following is an example that illustrates the process engineering part of chemical engineering: The difference between chemical engineering and chemistry The individual processes used by chemical engineers (eg. distillation or chlorination ) are called unit operations and consist of a chemical reaction mass- heat- and momentum- transfer operations. Unit operations are grouped together in various configurations for the purpose of chemical synthesis and/or chemical separation . Not all real processes, such as reactive distillation , are simple unit operations, but consist of intertwined transport and separation processes. Three primary physical laws underlying chemical engineering design are Conservation of mass Conservation of momentum and Conservation of energy . The movement of mass and energy around a chemical process are evaluated using Mass balances and energy balances which apply these laws to whole plants, unit operations or discrete parts of equipment. In doing so, Chemical Engineers use principles of
