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.
1. 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.
2. 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.
3. 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.
4. 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%.
5. 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.
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.
