List of engineering branches
Subdiscipline Scope Major specialties
Biomolecular engineering Focuses on the manufacturing of biomolecules Genetic engineering ( of whole genes and their chromosomes ) Immunology and biomolecular/biochemical engineering Engineering of DNA and RNA ( related to genetic engineering )
Materials engineering Involves properties of matter ( material ) and its applications to engineering Metallurgical engineering , works with metals Ceramic engineering works with raw oxide materials ( e.g . alumina oxide ) and advanced materials that are polymorphic , polycrystalline , oxide and non-oxide ceramics Polymer engineering works with polymer materials Crystal engineering works with the design and synthesis of molecular solid-state structures Biomaterials engineering works with natural and living systems
Molecular engineering Focuses on the manufacturing of molecules
Process engineering Focuses on the design , operation , control and optimization of chemical processes . These include natural and man-made materials , interaction of materials with machines , safety and health , energy conservation and waste and pollution control . This extends to plant design and layout , machine and wet process design and improvement and designing and creating products Petroleum refinery engineering works on the manufacture of refined products Plastics engineering works on the plastics products Paper engineering works on paper products Textile engineering works on fiber , textile and apparel products
Corrosion engineering Applies scientific knowledge , natural laws and physical resources in order to design and implement materials , structures , devices , systems and procedures to manage corrosion . Generally related to metallurgy , corrosion engineering also encompasses non-metallics including ceramics . Corrosion engineers often manage other not-strictly-corrosion processes including cracking , brittle fracture , crazing , fretting , erosion and more
Chemical engineering
Chemical engineering is the application of chemical , physical and biological sciences to the process of converting raw materials or chemicals into more useful or valuable forms .
Engineering is the discipline and profession that applies scientific theories, mathematical methods, and empirical evidence to design, create, and analyze technological solutions cognizant of safety, human factors, physical laws, regulations, practicality, and cost. In the contemporary era, engineering is generally considered to consist of the major primary branches of chemical engineering, civil engineering, electrical engineering, and mechanical engineering. There are numerous other engineering subdisciplines and interdisciplinary subjects that may or may not be part of these major engineering branches.
