How Does Industry Make Nitrogen

1. The working process is: the air is compressed by the compressor and enters the cold dryer for freeze-drying, so as to meet the dew point requirements of the pressure swing adsorption nitrogen generation system for the raw air. Then the oil and water in the feed air are removed through the filter and enter the air buffer tank to reduce pressure fluctuation. Finally, the pressure is adjusted to the rated working pressure through the pressure regulating valve and sent to two adsorbers (containing carbon molecular sieve), where the air is separated to produce nitrogen. Feed air enters one adsorber to produce nitrogen, and the other adsorber is desorbed and regenerated under reduced pressure. The two adsorbers work alternately to continuously supply raw air and produce nitrogen. Nitrogen is sent to the nitrogen buffer tank, measured by flowmeter, analyzed and detected by instrument, qualified nitrogen is used for standby, and unqualified nitrogen is vented (when the nitrogen generator is just started) 2.
