After Six Sigma PowerPoint Flashcards
Design for chemical plant
1 involves chemical technology 2 unit operations 3 instrumentation/controls 4 specialized equipment 5 safety considerations 6 materials of construction
- Chemical technology
What does it involve?
Deals with chemical changes and physical methods involved in industrial process
- Plant capacity
1 Before designing a process the product specifications need to be fixed
2 plant capacity cab be decided on demand or investment
- Plant capacity continued
3 investment depends on available technologies
4 consumption of raw materials and energy needs to be calculated through stoichiometric calculations

Process Research/Pilot studies
1 Process research is chemically feasible process
2 basic operating condition are investigated and info gathered from research to prepare a preliminary material report and energy balance flow sheet
3 pilot plant may be required first (error small not big)
4 manufacturing bulk drugs, eg. Antibiotics
….
4 advantages of pilot plants
1 help in ongoing improvement of process
2 improvement in product quality
3 reduction in process costs
4 Safety and minimizing pollution effects
8 advantages of pilot plants (continued)
5 manufacturing small volume can supply for commercial testing before doing large scale
6 selection of manpower - familiarity with chemical process and equipment, communication and observation skills
7 logging data can change - inexpensive to electronic instrumentation, trend analysis
8 can be used as training area
