How Does an Industrial Membrane Nitrogen Generator Work?
The membrane separation of gases is simple in concept. At the heart of technology are polymeric membrane materials that allow for the rapid passage of one gas while minimizing the passage of another when applying pressure gradient across the membrane. The below figure demonstrates the relative rates of common gases, here with the focus on the separation of O2 from compressed air to provide a high purity N2 stream. ATHENA ® polymer has the best separation efficiency and lowest unit power consumption, i.e. the best properties for allowing the fast gases (H2O, H2, He, H2S, CO2, O2) to permeate the membrane relative to the slow gases (Ar, N2, CH4, C2+, SF6).
