Working principle and production process of pressure swing adsorption nitrogen production system
Take carbon molecule sieve as absorbent. Under certain pressure, the adsorption capacity of carbon molecule sieve on oxygen is much higher than that of nitrogen. By switching on/off the pneumatic valves controlled by PLC program, the adsorption towers A and B works alternately, generating while pressure increased and regenerating after pressure reduced. The nitrogen and oxygen will be separated during the process, the purified nitrogen will be obtained then.
