Question: For the vacuum distillation of ethanol at 40 kPa, what is the gas velocity in the distillation column in meters per second?

The flow rate needs to be calculated based on the tower requirements. It should be 1~2 m/s.

Thank you for the advice. Question: For the same amount of evaporation, is the empty tower gas velocity the same for atmospheric distillation and vacuum distillation?
