Study Notes

Definition of Chemical Engineering

Chemical engineers integrate math, physics, chemistry, biology, and economics to tackle practical challenges.
Distinction lies in the application of chemistry alongside other engineering principles, increasing versatility.

Historical Development

Pre-18th Century: Industrial chemicals primarily produced through batch processing.
Industrial Revolution (1700-1800): Transition from batch to continuous processing methods.

Education Milestones

1882: First course in "Chemical Technology" introduced at University College London.
1885: "Chemical Engineering" course established at Central College in London.
1888: MIT launches Course X, emphasizing the combination of mechanical engineering with chemistry to address chemical product manufacturing.

Key Achievements in Chemical Engineering
