정의
Process design refers to the systematic development and engineering of chemical processes based on technical requirements, patent information, and experimental data. It involves transforming laboratory-scale or patent-based technologies into fully engineered process systems suitable for industrial production.
In chemical engineering, process design serves as the foundation for plant development, equipment selection, and operational planning. It connects chemical reactions with real-world industrial production systems.
Core Concept
Process design is not limited to drawing flow diagrams. It integrates multiple engineering disciplines, including:
- Reaction engineering
- Separation process design
- Heat and mass transfer analysis
- Equipment selection
- Safety and operability evaluation
The goal is to create a process that is technically feasible, economically viable, and safe for industrial operation.
