1. Kwa mpweya womwewo wa adsorbed (adsorbate) mu adsorprtion iliyonse, kutentha kwapansi, kuthamanga kwapamwamba ndi mphamvu yaikulu ya adsorbing.

2. pamene mayamwidwe amakhalabe okhazikika;mwinamwake, kutentha kwapamwamba, kuthamanga kwapansi ndi mphamvu yaing'ono ya adsorbing.Ngati ndi

kutentha kumakhalabe kosasinthika, desorption ndi decompression (vacuum pumping) kapena pansi pa kupanikizika koyenera kumatchedwa kuthamanga kwa kuthamanga.

adsorption (PSA) ngati adsorption pansi pa kuponderezedwa.

3. Monga tawonera pamwambapa, kukula kwa adsorption ya oxygen ndi nitrogen ndi carbon molecular sieve kumasiyana kwambiri.Nayitrogeni ndi mpweya akhoza kukhala

olekanitsidwa chifukwa cha kusiyana kwa kukula kwa mpweya ndi nayitrogeni adsorption mu mpweya pansi pa kukanikiza kwina.Mphamvu ikakwera,

sieve ya carbon molecular imadsorbetsa mpweya ndipo imapanga nayitrogeni;pamene kuthamanga kugwera mwachibadwa, sieve imawononga mpweya ndi

imapanganso nayitrogeni.Nthawi zambiri, jenereta ya nayitrogeni ya PSA imakhala ndi ma adsorbers awiri, omwe amatsitsa mpweya ndikutulutsa nayitrogeni,

ndipo zina zimawononga mpweya ndi kutulutsanso nayitrogeni.Mwa njira iyi, nayitrogeni imapangidwa mosalekeza.
