In an aromatic compound complex, why does the temperature in the xylene tower need to be around 300 degrees Celsius during distillation? ? ?

In the aromatic compounds processing complex, when the xylene column is used for distilling C8A, the temperature inside the column ranges from 270 to 300 degrees Celsius, whereas the boiling point of xylene is around 140 degrees Celsius. What is the reason for this? I’m new to the chemical industry; I hope experts can give me some guidance.
The xylene tower is the thermal heart of the aromatic complex, so the temperature there is higher.
But the boiling point of C9 is only a little over 150; won’t this affect the distillation process?
One of the functions of this tower is to heat other elements, so the pressure and temperature need to be increased.
