Introduction
This purifier adopts the OW process for oxygen purification. The feed oxygen enters the purifier, where impurities such as H₂, CO, CH₄, and NMHC in the oxygen are converted into H₂O and CO₂ by utilizing the characteristics of a high-temperature noble metal catalyst. These are then removed by a W (ambient-temperature adsorption reactor), which eliminates impurities such as H₂O and CO₂ from the feed gas. Once the bed reaches adsorption saturation, it undergoes heating for regeneration. The ambient-temperature adsorption reactors are designed with one in operation and one on standby, enabling continuous operation.

OW Process
Process Flow
Catalyst removes H₂、CO、THC
Adsorbent removes CO₂、H₂O
After the adsorption reactor reaches saturation, it is regenerated by oxygen purging with heating. Dual vessels switch over to ensure continuous gas supply.
