2. What is Chemical Engineering?
• Definition: Application of physical sciences
(e.g., chemistry and physics), life sciences, and
mathematics to process raw materials into
valuable products.
• Differs from Chemistry: Focuses on process
design and large-scale manufacturing.
• Brief History: Evolved in the 19th century with
the rise of the chemical industry.
3. Core Principles
• Thermodynamics: Energy and heat transfer.
• Fluid Mechanics: Behavior of fluids in systems.
• Heat & Mass Transfer: Essential for designing
reactors and equipment.
• Reaction Engineering: Chemical reaction
design and control.
4. Unit Operations
• Distillation: Separation of components based
on boiling points.
• Filtration: Separation of solids from fluids.
• Drying: Moisture removal.
• Absorption & Extraction: Separation based on
solubility.
5. Chemical Engineering Design
• Process Flow Diagrams (PFDs): Visual
representation of the process.
• Equipment Design: Sizing and specifying units.
• Safety Considerations: Crucial in chemical
plants.
6. Industries & Applications
• Petrochemicals: Fuels, lubricants.
• Pharmaceuticals: Drug manufacturing.
• Food Processing: Large-scale production of
food.
• Energy: Renewable and non-renewable energy
processing.
7. Modern Trends
