On azeotropic distillation
Thread Content
I would like to ask the experts: Benzene has an azeotrope with water, at an azeotopic temperature of 69.3 degrees; the benzene content in this azeotrope is approximately 91%. I think 69.3 degrees refers to the top temperature of the tower, rather than the bottom temperature. Right? Thank you!
The top temperature is basically at 70±0.5 degrees
Since an azeotrope has been formed, it must be in the gas phase; therefore, that is the temperature at the top of the tower.
Separation can be achieved when the temperature at the top of the tower is higher than the azeotrope temperature. Additionally, ask about the relationship between the azeotrope temperature and pressure changes.
