Consider the styrene production process flow diagram to answer the following: 1. In what area of the plant is the process shown in the diagram located? 2. How many computers have a parallel or backup unit in this process? What kind of teams are they? 3. How many reactors does the process have and how are they identified? 4.What kind of equipment is the V-401? If it were replaced by another of a different size, orientation and material with different operating conditions, how would you identify this new equipment?
