2.3 Optimising Production
Flow charts
Designing chemical-synthesis processes involves constructing reaction pathways that may include more than one chemical reaction.
The steps in industrial chemical processes can be conveniently displayed in flow charts.
- Interpret flow charts and use them for such purposes as identifying raw materials, chemicals present at different steps in the process, waste products, and by-products.
Video: Applying the Concepts
Industrial processes
Industrial processes are designed to maximise profit and to minimise impact on the environment.
- Explain how certain reaction conditions represent a compromise that will give maximum yield in a short time.
- Explain the impact of increases in temperature and pressure on manufacturing conditions and costs, and on the environment.
- Explain how use of a catalyst may benefit both the manufacturer and the environment.
