Introduction
This purifier employs the OW process for nitrogen purification. The feed nitrogen enters the purifier and first undergoes the O (Catalytic Oxidation) process. Utilizing the properties of a high-temperature noble metal catalyst, this process converts impurities such as H
2, CO, and CH4 in the nitrogen into H
2O and CO
2. Subsequently, the gas passes through the W (Ambient Temperature Adsorption Reactor), which effectively removes impurities like O
2, H
2O, and CO
2. Once the bed reaches adsorption saturation, it is regenerated by introducing hydrogen. The ambient temperature adsorption reactors are designed in a one-operating, one-standby configuration, enabling continuous operation.
