Chapter 1 diagrams for understanding chemical processes

Chapter 1:Diagrams for Understanding Chemical Processes

  • Block Flow Diagram

    • Basic Overview (Principles 1 layout)

    • Shows chemical processes, but types of equipment must still be determined


Chapter 1 diagrams for understanding chemical processes

  • Target product is 37% formaldehyde in water. Known as formalin

  • Occurs of a silver catalyst at 200 oC and 2 – 3 atm pressure

  • Reaction 1 is the predominant reaction

  • Develop a block flow diagram that describes the process

Process Flow Diagram

  • Process Flow Diagram

    • Gives all major equipment, sizes, and materials of construction so that costs can be determined.

    • Gives complete mass & energy balances with component flow rates, temperatures, pressures, vapor/liquid/solid fractions.

    • Utility requirements
