Study Notes
Definition and Scope
- Chemical engineering is a discipline that combines principles from chemistry, physics, and mathematics to design, operate, and optimize systems for the production of chemicals, fuels, and pharmaceuticals.
- It involves the development of processes and equipment for large-scale chemical manufacturing.
Key Concepts
Unit Operations
- Physical separations (filtration, sedimentation, crystallization)
- Chemical reactions (combustion, catalysis, biochemical reactions)
- Mass transport (diffusion, convection, absorption)
- Energy transport (heat transfer, momentum transfer)
Process Systems
- Batch processing: discrete batches of material are processed in a sequence of operations
- Continuous processing: materials are continuously fed and processed
- Hybrid processing: combination of batch and continuous processing
Plant Design and Operation
- Process flow diagrams (PFDs): graphical representations of process systems
- Piping and instrumentation diagrams (P&IDs): detailed diagrams of process equipment and piping
- Process optimization: analysis and improvement of process performance
Core Principles
Conservation of Mass and Energy
- Mass balances: accounting for the input and output of materials in a process
- Energy balances: accounting for the input and output of energy in a process
Thermodynamics
- Laws of thermodynamics (Zeroth, First, Second, Third)
- Equations of state (ideal gas, real gas, van der Waals)
- Phase equilibria (vapor-liquid, liquid-liquid)
Transport Phenomena
- Momentum transport (fluid flow, turbulence)
- Heat transport (conduction, convection, radiation)
- Mass transport (diffusion, convection)
Applications
Petroleum Refining
- Crude oil processing
- Fuel production (gasoline, diesel, jet fuel)
- Petrochemical production (plastics, fibers, adhesives)
Chemical Manufacturing
- Production of bulk chemicals (acids, bases, salts)
- Production of specialty chemicals (dyes, pigments, pharmaceuticals)
Biotechnology and Pharmaceuticals
- Fermentation and cell culture
- Downstream processing (separation, purification)
- Bioproduct development (vaccines, enzymes, antibodies)
