Abstract (AI)
A pressure swing adsorption cycle comprised of blowdown, purge, pressurization, feed, pressure equalization and rinse steps provided recovery from an atmospheric air feed, essentially dry and free of carbon dioxide, of a high yield of high purity nitrogen gas and a high yield of a product gas rich in oxygen as well as recovery of a residual feed byproduct gas for recycle with the air feed.
Key Findings
1
A pressure swing adsorption (PSA) cycle with blowdown, purge, pressurization, feed, pressure equalization, and rinse steps can produce high-purity nitrogen from atmospheric air free of CO2 and essentially dry.
2
The PSA cycle yields a high recovery of nitrogen while simultaneously producing a high-yield product gas rich in oxygen.
3
The process enables recovery of a residual feed byproduct gas suitable for recycle with the incoming air feed.
