What is the nitrogen at the top of the methanol thermal regeneration tower used for? Dalian University of Technology’s low-temperature methanol washing

What is the nitrogen at the top of the methanol thermal regeneration tower used for? In addition to the fear of cutting off the raw material gas or the negative pressure formed after the steam is interrupted, are there any other effects? Friends, please help explain.
Negative pressure may occur in the tower after the heat source is interrupted, and nitrogen prevents the tower from being collapsed.
It's for replacement when driving and parking, otherwise how would you replace it?
Negative pressure is formed after the material is interrupted, causing damage to the equipment. Replace it before starting the machine.
There is a self-regulating valve on the nitrogen pipeline to form a regulating loop with the tower top pressure to ensure that the tower top pressure is within a certain range.
For safety reasons, generally flammable and explosive media will be equipped with nitrogen seals. It can be used to supplement pressure to prevent negative pressure, or it can be replaced!
