PSA is the acronym for “Pressure Swing Adsorption”, which is the name of the process that takes place inside the Oxygen Generator Plant. PSA plants extract oxygen using a molecular sieve, which expels nitrogen and leaves a more purified oxygen product, which is stored in a tank until ready for distribution by a pipe system. The basic technologies of the PSA plant include: the air (feed) compressor, the air dryer, prefilter systems, the PSA generator, and the booster compressor. Review the Assist International webinar “Essential Considerations Related to a PSA Plant” HERE for more details. You may have also heard of “VPSA” – “Vacuum Pressure Swing Adsorption”.
