There are two main reasons for the high dew point of the nitrogen generator:
The gas output of nitrogen generator is too large, or the effect of carbon molecular sieve is not good.
The activated carbon in the adsorber is not replaced in time, or the filter element is damaged.
Removing moisture from the air is a necessary stage in the nitrogen production process. Usually using the two methods as below,
Use some porous substances to adsorb air to remove water such as adsorbents, and the adsorbents mainly is carbon molecular sieve.
Usually used in large low-pressure nitrogen generator, and remove water from the air in heat exchanger and other equipment.
