Why is the liquid level in the low-temperature methanol wash regeneration tower at the full scale, while the liquid level in the lean methanol storage tank is at the lower limit?

Dear friends: After the thermal regeneration tower was shut down for evacuation and restarted, its liquid level reached the full scale. The control valve of the lean methanol tank was opened fully, which caused the liquid level in that tank to rise to its lower limit. The gas phase pressure of the thermal regeneration tower was set at 0.20 MPa. The temperature at the tower bottom is controlled at 97 degrees, and the pressure in the methanol-deficient tank is kept at 0.054 MPa. I would appreciate your guidance on what could be causing this phenomenon
There is air resistance in the coiled tube heat exchanger
Check the pipes in the middle for issues with heat exchange and valves. Either there is no pressure difference, or there is a problem with the pressure gauge.
