  • Pressure Swing Adsorption - an overview |

    Pressure swing adsorption systems for oxygen production were first used in the 1970s. Since then, the technology has rapidly improved. The early systems operated the entire operational sequence above atmospheric pressure. However, incorporation of a sub-atmospheric regeneration step much more fully utilized the characteristics of the adsorbent.
