High-Purity Oxygen Production by Pressure Swing Adsorption

The oxygen purity produced by pressure swing adsorption (PSA) processes is limited to 95%, with the rest being essentially argon. This oxygen grade is suitable for many industrial applications. However, medical applications, cylinder filling, oxyfuel cutting in metal fabrications, and fuel cells technology with recirculation loop, among others, require oxygen with a higher purity (99% or above).
