Chemical Engineering
Chemical engineering is the discipline of transforming raw materials into useful products through controlled processes, applying principles from chemistry, physics, mathematics, biology, and economics. It designs and operates chemical plants, from laboratory-scale nanotechnology to vast industrial processes, converting chemicals, living cells, and energy into valuable forms. This craft encompasses plant design and operation, safety assessments, and process control, making it a critical link in manufacturing everything from pharmaceuticals to fuels.

Emerging roles
-
Chemical engineer — carbon-capture processes
Emerging application area: Carbon capture requires separating carbon dioxide from a gas stream and connecting that process to handling and storage. Investigate energy requirements, process integration and what happens to the captured material. This is an application to investigate, not a forecast of job vacancies.
Skills to build
- Separations
- Process design
- Mass and energy balances
