Product Description

While you do not ask high for O2 purity, seems like the PSA oxygen generator is probably a good choice for you. Because the PSA oxygen plant features both smaller footprint and low power consumption. Moreover, it consequently features instant start and less investment, as well as fully automatic running.

Description

Applications

Especially relevant, the PSA oxygen generator may probably serve as either an EAF steelmaking oxygen generator or an oxygen concentrator that is for sewage treatment. Furthermore, it is widely used in steelmaking and glass melting, bleaching of pulp and paper; in addition, water treatment and non-ferrous metal smelting, petrochemical and chemical industries, ore processing and aquaculture, fermentation, and other fields.

Note: The above data is based on the following design conditions: atmospheric pressure: 101.325 KPa; ambient temperature: 21 °C; relative humidity: 80%. The power consumption is converted into unit power consumption for 100% pure oxygen generation.

Technical Advantages

Advanced single-vessel process

Compared with the traditional double-vessel process, the world-leading single-vessel process requires less equipment but brings more stable performance with easier operation and maintenance.

: High efficiency lithium-based molecular sieve

The third generation of high-efficiency lithium-based oxygen generation molecular sieve (PU-8) has a lithium ion exchange rate of over 99%, bringing plenty of advantages such as high strength, high nitrogen and oxygen selectivity, large bulk density, uniform particles, long service life, etc. In combination with the proprietary automatic filling technology, the stability of the molecular sieve bed is effectively guaranteed.

: Special valves for oxygen generation

Special valves for oxygen generation are more suitable for VPSA oxygen process, offering good sealing, fast switching speed, stable performance and other characteristics, along with outstanding low failure rate and easy maintenance.

: Modular integrated design

Compared with the conventional double-vessel process, the equipment is more compact and the plot area can be reduced by more than 20%.

Low operation cost

The power consumption of oxygen is as low as 0.29～0.32kWh/Nm3, the annual maintenance cost is 30% lower than that of a common PSA oxygen generator. The annual comprehensive operation cost is also reduced by more than 50%, compared with the cost of common PSA oxygen generator or purchasing liquid oxygen.

Technical Principle

Adsorption process: the pressurized ambient air is passed through the adsorption vessel, where the impurity gases (i.e. predominantly nitrogen) are preferentially adsorbed by the molecular sieve. Oxygen is enriched at the top of the adsorption vessel, then enters an oxygen buffer tank to supply oxygen to the downstream;

Desorption process: after the molecular sieve is saturated by adsorption, the valve is switched to allow the blower to reverse act and vacuumize, thus restoring the adsorption capacity of the molecular sieve. In this stage, oxygen is continuously supplied to the downstream from the oxygen buffer tank.

Shipping & Delivery

The transportation of large equipment, such as the air separation unit, PSA gas plant, and the CO2 recovery plant, has always been a concern of overseas customers. The unloading and lifting must be careful. How to reduce extra handling fees is also one of the issues to be taken into consideration.

We can provide you with a worry free delivery:
1. We maintain long-term cooperation with some partner forwarders. So we can:

tell the accurate shipping date and quote the best shipping rates
book appropriate cargo space and choose the best shipping method: container, roll-on-roll-off ship, open top container or bulk carrier
make appointment for commodity inspection, arrange shipment, and prepare necessary documents for customs clearance

2. We have our own private wharf. Even 300m3 pressure vessels can be loaded within the factory and sent to Shanghai port.

3. We are quite experienced in loading and fixing containers, protecting the cargo from any possible damage on the way. The cargos will be in perfect condition upon the arrival at the destination.

4. The bulk ship and roll-on-roll-off ship are for the delivery of large and bulky cargos. The destination port may not be equipped with large cranes, and at somewhere the lifting charges are quite expensive. Taking these factors into consideration, we will choose ships equipped with cranes to reduce costs for customers. Our forwarder will arrange appropriate crane lifting and attach the cargo to the deck or cabin.

5. We will track the delivery until you receive the cargo.

6. The vast majority of customers receive cargos intact, but there is still likeliness of slight painting scratches. In this occasion, we suggest customers to fix the paint on their own if necessary. In addition, customers may purchase transport insurance to further reduce the risk of cargo damage.

In addition to PSA Oxygen Generators, we also produce PSA Oxygen Generators, storage tanks, heat exchangers and other products. If you are interested in VPSA Oxygen Systems or other products, please feel free to send an email to [email protected]. We will be very happy to serve you.
