Process Design - Design Considerations

Design Considerations

Designs have objectives and constraints, and even a simple process requires a trade-off among such factors.

Objectives that a design may strive to include:

  • Throughput rate
  • Process yield
  • Product purity

Constraints include:

  • Capital cost
  • Available space
  • Safety concerns
  • Environmental impact and projected effluents and emissions
  • Waste production
  • Operating and maintenance costs

Other factors that designers may include are:

  • Reliability
  • Redundancy
  • Flexibility
  • Anticipated variability in feedstock and allowable variability in product.

Famous quotes containing the word design:

    “The reason American cars don’t sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. That’s why the American auto industry is in trouble: no design, no desire.”
    —Karl Lagerfeld (b. 1938)
