Oxy-Rich Oxygen Enrichment
Oxy-Rich Oxygen Enrichment : A version of the PSA process for producing air enriched with oxygen in the range 23 to 50 percent. It is for use where higher degrees of enrichment are unnecessary - for enhanced combustion, and for improved oxidation in chemical and biochemical reactors. It is more energy-efficient than the standard PSA process because only some of the air is compressed to the highest level of the cycle
