PSA Oxygen Generator
Two adsorption tower will be installed in parallel in PSA oxygen generator, one tower begins the adsorption phase while other tower regenerates by de-pressurizing. The PLC controller manages process valves with built-in logic for an automatic stop/start for continuous oxygen production. The whole system is composed of air purification system, air storage tank, separating system of nitrogen and oxygen, and oxygen buffer tank.
- Oxygen capacity: 5-200Nm³/h
- Oxygen purity: 90%-94%
- Oxygen pressure: 0-0.5Mpa
- Oxygen dew point: -40℃ (atmospheric pressure)
- Installed with compressed air purifier and dryer to prolong the service life of molecular sieves.
- Adopt advanced pneumatic shut-off valve for fast start and stop without leakage, can meet frequent usage with high reliability and service life.
- Adopt automatic PLC controller with low annual operating failure.
Our PSA oxygen generator can separate oxygen from compressed air utilizing zeolite molecular sieve (ZMS) when pressurized. As nitrogen has a higher diffusion rate in ZMS pores, the sieve will adsorb the nitrogen and moisture over oxygen, allowing the oxygen to pass as product gas at pressure. After de-pressurizing, the sieve releases adsorbed gases into the atmosphere, and the process can then be repeated.
- Electric furnace steelmaking: decarburization, oxygen assisted heating, foam slag dissolving, metallurgical control and post-process heating
- Wastewater treatment: aerobic aeration of activated sludge, pond oxygenation and ozone sterilization
- Glass melting: oxygen combustion and solubilization, cutting, increasing glass production and extending furnace life
- Pulp bleaching and papermaking: large volume oxygen of low price can help conversion of chlorine bleaching to oxygen-enriched bleaching, as well as support sewage treatment.
- Non-ferrous metal smelting: oxygen will be for smelting steel, zinc, nickel, lead, etc. PSA is gradually replacing cryogenic method in this process
- Field cutting construction: containerized or small oxygen generator can meet the requirements for oxygen used in field steel pipe, steel plate cutting.
- Petrochemical and chemical industries: oxygen-enriched air can be used to replace atmospheric air to carry out oxidation reaction in petroleum and chemical processes, which can increase the reaction speed and the yield.
- Ore treatment: used in production processes of precious metal such as gold to increase the extraction rate
- Aquaculture: oxygen-enriched aeration can increase the dissolved oxygen volume in the water, largely increasing fish production and enabling intensive fish farming.
- Fermentation: using oxygen-enriched air to replace atmospheric air to supply oxygen for aerobic fermentation can dramatically increase efficiency.
- Drinking water: supply oxygen to the ozone generator for sterilization.
