what is pressure swing adsorption nitrogen plant
under a certain pressure, the nitrogen production unit uses the great difference in the diffusion rate of nitrogen and oxygen in the air on the carbon molecular sieve. in a short time, a large number of oxygen molecules are adsorbed by the carbon molecular sieve, and the nitrogen molecules are enriched in the gas phase to achieve the separation of oxygen and nitrogen.
since the adsorption capacity of carbon molecular sieve for oxygen varies significantly with pressure, reducing the pressure can desorb the oxygen molecules adsorbed by carbon molecular sieve, so that the carbon molecular sieve can be regenerated and reused. two adsorption tower processes are adopted, one tower adsorbs and produces nitrogen, and the other tower desorbs and regenerates. the cycle is alternating to continuously produce high-quality nitrogen.
special carbon molecular sieve protection measures to prolong the service life of carbon molecular sieve; famous brands are adopted for key components, which is an effective guarantee for equipment quality; the national patented automatic venting device has a variety of fault diagnosis, alarm and automatic processing functions; optional touch screen display, dew point detection, energy saving control, dcs communication, etc.
