1. 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

2. 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

3. 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
