- •
Simultaneous CH4 capture and N2 purification was achieved with a DR-PSA process.
- •
A dilute feed with 2.4% CH4 was enriched 21 times with a pressure ratio of only 3.6.
- •
Methane in the light product was reduced to 3000 ppm to produce a clean N2 vent.
- •
Capture of dilute methane by this DR-PSA process is energetically self-sustainable.
