Emkhathini, cishe i-78% iyi-nitrogen (N2) futhi isondele ku-21% i-oxygen (O2) ikhona. Ukuthola i-nitrogen emoyeni, ubuchwepheshe be-PSA busetshenziswa izimboni ezahlukene kuye ngezidingo zazo. Amasefa e-Carbon molecular ayingxenye eyinhloko yezinhlelo ze-press swing adsorption (PSA). I-CMS ingasetshenziselwa ukukhiqiza i-nitrogen ngenxa yokuhlobana kwayo okuphezulu kanye nekhono lokukhangisa ama-molecule e-oksijini.
Umoya ocindezelwe osuka ku-compressor uyacindezelwa futhi ungena embhoshongweni wombhede we-CMS. Umbhoshongo ugcwele i-CMS futhi unesakhiwo se-cavernous. Futhi ngenxa yokuhlobana kwayo okukhethekile kwama-molecule omoya-mpilo, i-nitrogen ayikhangiswa yi-CMS. Ngakho-ke, umoya ocebile nge-nitrogen ungatholwa njengokuphumayo. Uma lo mbhoshongo kanye ne-CMS sezifinyelele izinga lokugcwala kwawo, umoya udlulelwa embhoshongweni wesibili. Manje umbhoshongo wesibili uzothola umoya ocindezelwe. Phakathi nale nqubo, ikholomu yangaphambilini izosebenza njengemodi ye-desorption. Lokhu kungenziwa ngokukhulula ukucindezeleka. Ngakho-ke ama-molecule e-oksijini akhangisiwe azosuswa. Inqubo iphinde yenziwa ngokuhlinzeka nge-nitrogen ehlanzekile njengokuhlanza. Lokhu kukhangisa kanye ne-desorption kuzokhiqiza i-nitrogen njengomkhiqizo. Phakathi nenqubo yokukhipha umoya, umoya-mpilo uyakhishwa ukuze umbhede we-CMS ulungele umjikelezo we-adsorption olandelayo. Ngakho-ke, izisefo ze-carbon molecular (CMS) zidlala indima ebaluleke kakhulu enqubweni yokukhiqiza i-nitrogen.
