Aromatic hydrocarbon refining
Thread Content
With the top pressure of the aromatic hydrocarbon refining dehydration tower controlled at 0.3 MPa, the bottom temperature at 134°C, and the top temperature at 107°C, will a large amount of benzene vaporize from the tower top?

Check the material property data sheet and you’ll understand…
Check what the boiling point of benzene is at 0.3 Mpa, and compare it
