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.

Rubber & Tyre
Anti-oxidation is necessary in the whole production process of rubber & tyre raw materials. As an inertia gas, nitrogen can act as an antioxidant in the preservation of raw materials in rubber tires, rubber vulcanization, molding, inflatable packaging, etc.
-
Textile
In the textile industry, nitrogen generator can supply nitrogen gas to protect the textiles from oxidation and damage during the production process, preventing color default caused by oxidation.
-
Electronics
Since high purity nitrogen gas is required as carrier gas or protective gas in the production process of electronics, so that nitrogen generator is essential in the production of electronic components.
-
Environmental Protection
With the increasing attention paid to environmental protection, more and more enterprises began to invest on the low-carbon emission of waste water and materials, for example, the oil sludge produced by petroleum mining, especially hydrocarbon gases, should be heated without oxygen in the heat treatment process for the safety and processing effect.
-
Glass
The traditional glass molding process can generally be divided into three steps: forming, annealing and cooling.
