Study Notes
Definition and Scope of Chemical Engineering
- Combines math, physical sciences (physics, chemistry), life sciences (biology, microbiology, biochemistry), and economics to solve practical problems.
- Distinct from other engineering disciplines due to the application of chemistry.
- Versatile discipline; nearly all physical phenomena can be expressed through the integration of these four scientific fields.
Historical Development
- Pre-18th Century: Industrial chemicals mostly produced via batch processing.
- Industrial Revolution (1700-1800): Transition from batch processing to continuous processing.
- 1882: First course in "Chemical Technology" introduced at University College London.
- 1885: "Chemical Engineering" course launched at Central College, later known as Imperial College, London.
- 1888: MIT introduces Course X, aimed at blending mechanical engineering with chemistry applications.
Key Achievements in Chemical Engineering
- Crude Oil Processing: Development of methods to "crack" long carbon chains in crude oil, producing smaller molecules such as ethylene and propylene.
- Plastics Development: Contributions to the creation of essential plastics like nylon, PVC, acrylics, and polyethylene since the 1930s.
- Synthetic Fibers: Introduction of rayon and nylon; extensive manufacturing of diverse synthetic fibers for various applications including clothing and textiles.
