Exercise 1:
Shutdown of theC3‐C4 separation unit
You should propose, critically discuss, and analyze the shutdown strategy for the C3‐C4 separation section.
To compare the shutdown procedures, you are advised to consider:
The amount of product out of specification;
The energy consumption during the out of specification period;
The shutdown time.
Assumptions
Initially, the distillation column is working in stationary conditions and in absence of external disturbances.
