What is the significance of the pressure differences across various columns in low-temperature methanol washing for operation? What can be determined from the pressure difference?

Dear sea friends: How should each column in the low-temperature methanol washing process be operated based on the column pressure difference? What is the significance of tower pressure difference for tower operation?
The tower pressure can be used to determine the quality of absorption as well as the distribution of gas and liquid
It can reflect the load condition inside the tower, and is related to factors such as the upward gas flow rate, liquid feed rate, and the amount of liquid retained due to dirty trays. The pressure difference in the column for low-methane separation isn’t as important as that in a distillation column, but it can still indicate whether the tower is overloaded or experiencing flooding
Under normal circumstances, the pressure difference in the methanol water column fluctuates relatively significantly, which mainly reflects the operating condition of the distillation tower.
