Abstract EN
The separation of air by carbon molecular sieve (CMS) adsorption was studied in this work over a range of adsorption pressure of (2–8) bar.
Breakthrough curves showed no significant effect of the pressure on product nitrogen purity and adsorbent capacity above 4 bar.
Maximum purity of about 98% is observed for time up to 60 s.
Adsorbent capacity obtained is in agreement with multicomponent Langmuir isotherm up to 4 bar.
Maximum constant adsorbent capacity of about 0.1 mol O2/kg CMS is obtained for pressure above 4 bar.
For PSA two columns 6-steps process, no significant effect of the pressure on the product purity above 4 bar.
The purity increases with decreasing the productivity.
Maximum purity of 97.6% is obtained at productivity of 156 lit/kg CMS.hr, cycle time of 100 s, and purge flowrate of 1 lit/min.
The productivity of 606 lit/kg CMS.hr is obtained at purity of 94%, cycle time of 60s, and purge flowrate of 4 lit/min.
