Reasons for the increased pressure difference and suspension in the liquid nitrogen washing tower.

Upon solving, it shows afternoon twice; the load has not been adjusted, and it has already reached the designed level.
This has nothing to do with the morning or afternoon, right?
Only then can we determine what’s going on
Fluctuations in gas volume can also cause liquid blockage; please explain the specifics more clearly
It might be that the high temperature of the purified gas leads to an increased evaporation rate of liquid nitrogen, thereby raising the pressure difference; if the liquid level is automatically regulated, it is possible to check the changes in valve position.
