Why is the temperature of nitrogen exiting the distillation tower higher than the temperature of air entering the distillation tower?

Check the main heat exchanger channels to see if there is still a heat source with a temperature higher than that of the air entering the tower~

Let’s check the two thermometers anyway; this is too unscientific

The heat flow in the heat exchanger is air, while nitrogen is the cold stream; conventionally, the value for air should indeed be higher. If the instrument is not faulty or drifting, check whether there is a difference between night and day; in the past, sunlight during the day has affected temperature measurements.
