Problem 1. Answer the following questions

1.For the first heat exchanger in the process (E-401), what heat transfer surface does it have and how much heat is exchanged? 2. Check the material between the streams 5, 6 and 25 and verify the design of E-401. 3. Why the process uses a steam heater (H-401) instead of a Heat exchanger with hps? 4. What is the purpose of E-403 and what can you do with the hps leaving the exchanger? 5. What type of utility is required in E-405? At what temperature is the utility feed (propose an estimated temperature)? 6. What is the material from which the first reactor is made? What volume of catalyst does the reactor have? 7. Explain the control loop in stream 5 and 6. 8. Why the process has two reactors (R-401 and R-402)?
