Chemical Engineering
Application of physical sciences, mathematics, and economics to transform raw materials into valuable products via food-chemistry and physical unit operations. Focuses on design, analysis, optimization, and scaling of processes.
Fundamental Principles
- Chemical thermodynamics: Energy balances, phase equilibria, and process feasibility.
- Transport phenomena: Conservation of mass, momentum, and heat transfer.
- Reaction kinetics: Rate laws, mechanisms, and reactor design.
- Process control: Automation, feedback loops, and system stability.
- Catalysis: Acceleration of reaction rates and selectivity using catalysts.
Key Applications & Systems
- Petrochemicals: Refining, cracking, polymerization, and fuel synthesis.
- Pharmaceuticals: Bioprocessing, fermentation, and drug synthesis.
- Environmental engineering: Emissions control, wastewater treatment, and remediation.
- Materials science: Development of functional materials and nanotechnology.
- Automotive emissions management:
- catalytic-converter technology represents a critical deployment of heterogeneous catalysis to reduce toxic vehicular exhaust.
- Utilizes three-way catalyst mechanisms to simultaneously oxidize carbon monoxide and unburnt hydrocarbons while reducing nitrogen oxides.
- System architecture employs ceramic honeycomb or metal foam substrates coated with high-surface-area washcoats and active precious metal nanoparticles (Platinum, Palladium, Rhodium).
- High loading of rhodium and platinum group metals creates significant material value density, driving specific theft dynamics and supply chain vulnerabilities; see Catalytic Converter Report: History, Emissions Role, and Theft Dynamics.
