What is the significance of monitoring the pressure difference in a distillation tower?
On one hand, it is the gas velocity; on the other hand, it is the tower load
The column pressure drop arises from the pressure drops across each tray; these tray pressure drops are related to the separation efficiency (gas-liquid equilibrium) at each layer of trays. The tray pressure drops are caused by the pressure drop as the gas passes through the tray elements, as well as by the pressure drop resulting from the height of the liquid layer on the tray. Generally speaking, pressure drop refers to the separation efficiency of the tower and its operating load; if this pressure drop is too high or too low, it will prevent the tower from functioning properly, leading to incidents such as leaks or flooding, and causing the tower to lose its separation capability. Furthermore, under normal conditions, assuming the product quality is maintained, the greater the pressure drop in the tower, the higher the energy consumption, which is neither economical nor efficient
Measure the pressure drop in the packed tower to prevent packing blockage and flooding.
