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.
Synthetic Rubber: Advancements in synthetic rubber production.
Air Processing: Innovations in purifying and utilizing oxygen and nitrogen from air.
Semiconductor Fabrication: Essential role in the electronics and computing fields.
Medicine Development: Collaboration with medical professionals to create drugs, prosthetics, and support systems; significant involvement in mass-producing antibiotics like penicillin.
Environmental Protection: Active engagement in technologies for pollution cleanup and prevention.
