Abstract
|
The performances of two types of zeolite 5A and zeolite 13X in oxygen separation from air with a
two-bed six-step pressure swing adsorption (PSA) system were investigated using mathematical
modeling. The effects of feed flow rate, adsorption step pressure, adsorption step time and purge
to feed ratio on oxygen purity and recovery are studied. Comparison of two types of zeolites shows
that the PSA process performance (in terms of purity and recovery) was better with zeolite 13X
than the zeolite 5A. Furthermore, Results of simulation indicated a very good agreement with some
current literature experimentally work.
