What is Chemical engineering?
{{main|Engineering}} [[File:Trianel Kraftwerk HammU.jpg|thumb|Trianel power plant in Hamm-Uentrop.]]'''Chemical engineering''' is a branch of [[engineering]] dealing with [[chemistry]] that came to existence in the early [[20th century]].<ref>From Petroleum to Penicillin. The First Hundred Years of Modern Chemical Engineering: 1859–1959. – Burnett, J. N.</ref> Before this time, chemical plants were designed by chemists, who were trained to work on a small scale only. A chemical engineer typically works in the design and supervision of chemical manufacturing processes. Chemical engineers may use their skills to solve problems in the production systems of food, medicine, leather, as well as in [[Refinery|refineries]].<ref>{{Cite web|last=Josef|date=2022-09-06|title=The 34 Best Paying Jobs in Major Chemicals In 2022|url=https://www.sscholarscenter.com/best-paying-jobs-in-major-chemicals/|access-date=2022-12-12|website=sScholars Center|language=English}}</ref><ref>{{Cite web|last=Bican|first=Josef|date=2022-06-09|title=THE 34 BEST PAYING JOBS IN MAJOR CHEMICALS IN 2023|url=https://www.sscholarscenter.com/best-paying-jobs-in-major-chemicals/#What_are_Chemical_Studies|access-date=2022-12-12|website=sScholars Center}}</ref> Chemical engineering combines the jobs of a [[chemist]] and that of [[manufacturing engineering|industrial engineer]]. This makes factories more efficient and chemicals much cheaper as they can be produced for less money. [[Optimization]] is a technique used for this. Chemical engineering uses [[physics]] (the [[science]] of moving [[object]]s and [[Force (physics)|forces]]), chemistry (the science of [[substance]]s), and [[mathematics]]. There are many different types of [[job]]s for people with [[academic degree|degrees]] in chemical engineering. Some new topics in chemical engineering include: * environmental sanitation at [[factory|factories]] (making certain that [[nature]] is not hurt by the factories); * developing types of [[energy]] other than those from [[gas]] or [[oil]]; * [[biomedical
