As the feed rate increases, the pressure at the top of the distillation tower rises

I have a question: When the feed rate increases and a new equilibrium is established, why does the pressure at the top of the distillation tower rise? How does the quality of the product at the tower top change? From a theoretical analysis, is it possible to operate the tower top pressure back to normal to establish a new equilibrium?
Sustained increase or sudden fluctuations? There is usually stage-by-stage control, and the fluctuations stabilize after a while. Have there been any changes in the properties of the raw materials?
{:3_50:} With a higher volume of work, the pressure must increase. . . It’s like with a pipe: if you want it to transport more, you can only increase the pressure and speed; that’s normal
An increase in the feed rate leads to an increase in the tower load, causing a temporary disruption of equilibrium; however, as adjustments are made, equilibrium is gradually re-established. There may be an increase in both the gas and liquid phases, but under proportional control, the situation gradually stabilizes, with a slight increase in the gas discharge volume
