What does the operating pressure of a distillation tower refer to? Thank you
According to the definition of operating pressure for a vessel: the highest pressure that may be reached at the top of the vessel under normal operating conditions. The operating pressure of a distillation tower should refer to the operating pressure at the top of the tower. For your reference.
Yes, it refers to the pressure at the top of the tower.
Isn’t the pressure at the top of the tower the pressure of the condenser? It should be the pressure of the first actual tray in the tower
The operating pressure of a distillation tower should refer to the operating pressure at the top of the tower. The pressure at the top of the distillation tower affects the quality of the product, and this can be adjusted by using the reflux ratio and the amount of water circulating in the distillation tower’s condenser. The pressure at the bottom of the distillation tower is related to the consumption of raw materials and whether all the active components have been distilled out; this can be adjusted by controlling the amount of steam used in the reboiler.
