The pressure difference in the desulfurization solvent regeneration tower refers to the difference between the top and bottom of the tower?

As the title says. Is it the top of the tower and the bottom of the tower? Is an excessive pressure difference caused by the top of the tower being higher than the bottom, or something else?
It’s supposed to be this way. However, the pressure control point of the regeneration tower is generally the pressure at the outlet of the acid water tank after cooling. In fact, even when there is a pressure display at the top of the tower, there are differences among the various pressure measurement points located at the top of the tower and along its pipelines.
A high pressure difference means that the pressure at the top of the tower is higher than the pressure at the bottom of the tower, right?
Pressure difference refers to the gap between pressures; a high pressure difference means that this value has increased. It might be the low pressure at the top of the tower that causes this larger difference. Are you asking if the pressure at the top of the tower is higher than that at the bottom? How can the pressure at the top of the tower be higher than that at the bottom, when the reboiler is at the bottom, the gas source is at the bottom, and the pressure source is also at the bottom?
The tower pressure difference should be the pressure difference between the upper and lower parts of the tray; if the pressure measurement point at the top of the tower is located too far back, it may not reflect the actual pressure difference in a timely manner. The pressure difference is too large; it should be that the pressure at the top of the tower is low while the pressure at the bottom is high, with the bottom of the tower being under pressure
