Why is the reflux temperature at the top of the benzene column maintained at 60°C in aromatic separation?
It’s related to the operating pressure and the cooling medium, I guess
Pay attention to whether there are any azeotropes present; for example, the boiling point of the azeotrope formed by benzene and water is around 70 degrees.
If maintenance at that level is required in terms of operation, it means that the bubble point temperature corresponding to the operating pressure specified in the design is 60°C (without taking into account subcooled reflux), and 60°C is also required during operation
