Introduction to chemical process design; objectives, conceptualization, and economics. We cover preliminary design (process flow diagrams) to detailed process definition with techniques to design heat exchange networks and separation systems. Safety, health, and environmental issues are addressed. The course also covers costing equipment to overall plant economic evaluation. We discuss trade-offs between upfront investment and annual operating expenditures. Optimization techniques to improve energy efficiency, conversion, selectivity, and yield are discussed. A major design project allows students to apply their skills to a complex process.
