Mumhepo, inenge 78% initrogen (N2) uye pedyo ne21% oksijeni (O2) iripo. Kuti uwane nitrogen kubva kumhepo, tekinoroji yePSA inoshandiswa nemaindasitiri akasiyana zvichienderana nezvavanoda. Carbon molecular sieves ndiyo yakakosha chikamu chekumanikidza swing adsorption (PSA) masisitimu. CMS inogona kushandiswa kugadzira nitrogen nekuda kwehukama hwayo hwepamusoro uye kugona kushambadza mamorekuru eokisijeni.

Mhepo yakamanikidzwa kubva kune compressor inomanikidzwa uye inopinda muCMS bed tower. Iyo shongwe yakazadzwa neCMS uye ine cavernous chimiro. Zvakare nekuda kwehukama hwayo hwakakosha hweokisijeni mamorekuru, nitrogen haina kushambadzwa neCMS. Naizvozvo, mhepo ine nitrogen-yakapfuma inogona kugamuchirwa sekubuda. Kamwe iyi shongwe neCMS yasvika pakuzara kwayo, mhepo inopfuudzwa kune yechipiri shongwe. Iye zvino shongwe yechipiri ichagamuchira mweya wakamanikidzwa. Munguva iyi, iyo koramu yapfuura ichaita se desorption mode. Izvi zvinogona kuitwa nekusunungura kushushikana. Iwo adsorbed okisijeni mamorekuru anozove akasvibiswa. Iyo nzira inoitwa zvakare nekupa yakachena nitrogen sekuchenesa. Iyi adsorption uye desorption inoburitsa nitrogen sekubuda. Munguva ye desorption process, okisijeni inodzingwa saka mubhedha weCMS wakagadzirira kutenderera kunotevera kweadsorption. Nokudaro, carbon molecular sieves (CMS) inoita basa rakakosha zvikuru mukugadzirwa kwenitrogen.
