<prompt> Kubizwa ngokuthini ukususa i-nitrogen ku-O2? Njengoba kunikezwe umbuzo odlule, bhala umongo onempendulo yawo. Kungaba imisho engu-1 kuya kwengu-20. Umongo:  <response>: Enye indlela eyinhloko yokukhiqiza igesi ye-O2 ihilela ukudlulisa umfudlana womoya ohlanzekile, owomile ngomunye umbhede wezinhlayiya ezimbili ezifanayo ze-zeolite, ezifaka i-nitrogen futhi zikhiphe umfudlana wegesi ongu-90 kuya ku-93 O2. Ngasikhathi sinye, igesi ye-nitrogen ikhishwa komunye umbhede we-zeolite ogcwele i-nitrogen, ngokunciphisa ingcindezi yokusebenza yekhamera nokuguqula ingxenye yegesi ye-oxygen kusuka embhedeni womkhiqizi ngayo, ngendlela ephambene nokugeleza. Ngemva kwesikhathi esibekiwe somjikelezo ukusebenza kwemibhede emibili kuyashintshana, ngaleyo ndlela kuvumela ukunikezwa okuqhubekayo komoya-mpilo onegesi ukuze upompwe ngepayipi. Lokhu kwaziwa ngokuthi i- pressure swing adsorption. Igesi ye-oxygen itholakala kakhulu ngalezi zindlela ezingezona ze-cryogenic bheka futhi i-vacuum swing adsorption ehambisanayo.
