Chemical engineers develop and design chemical manufacturing processes.

Chemical engineering is a branch of engineering science or engineering that studies the processing of raw materials into goods more useful, can be finished or semi-finished goods. Chemical engineering science applied mainly in the design and maintenance of chemical processes, both on a small scale or a large scale such as factories.

Chemical engineers whose job is responsible for the design and maintenance of chemical processes on the scale of the plant known as "engineer" process (process engineer). In addition, modern chemical engineering engineers also conduct research aimed at finding materials and new techniques, which sometimes also associated with a variety of other disciplines, such as nanotechnology, fuel cells, and biomedical engineering.

In chemical engineering, there are two major subgroups that include:

1) to design, build, and operate plants / factories and chemical processes in it and 2) develop new substances or the development of substance earlier on a variety of products that span ranging from food and beverage to cosmetics, cleaning products, and pharmaceuticals.
