Cryogenic Air Separation
The air is compressed and cooled to a liquefied state before entering a distillation tower, where it is fractionated based on the boiling point difference between oxygen (−183 °C) and nitrogen (−196 °C) to obtain high-purity oxygen (over 99.5%).
This method is suitable for large power plants and can continuously and stably provide large flow and high-purity oxygen.
Pressure Swing Adsorption (PSA)
Adsorbents are used to selectively adsorb nitrogen between high and low pressures to achieve oxygen enrichment.
PSA has a fast response and can be used as an auxiliary or backup gas source. It is suitable for power plants or small and medium-sized devices with frequent load fluctuations.
Membrane Separation Technology
Oxygen in the air is separated by selective membranes to obtain low to medium purity oxygen.
It is suitable for flexible supply demand or short-term load fluctuation adjustment, with a fast response speed, but the purity is relatively lower than the low-temperature liquefaction method.
