<prompt> Unobvisa sei nitrogen? Tichifunga nezvemubvunzo wapfuura, nyora mashoko akapoteredza mhinduro yacho. Inogona kuva mitsara 1 - 20. Mashoko akapoteredza:  <response>: Imwe nzira huru yokugadzira O2 gasi inosanganisira kupfuudza rwizi rwemhepo yakachena, yakaoma nomubhedha mumwe wezviviri zvakafanana zvezeolite molecular sieves, izvo zvinopinza nitrogen uye zvinopa rwizi rwegasi urwo rwuri 90 kusvika ku93 O2. Panguva imwe chete, gasi re nitrogen rinoburitswa kubva kune rimwe denga re nitrogen-saturated zeolite, nekuderedza kumanikidza kwekushanda kwekamuri uye kutsausa chikamu chegasi re okisijeni kubva mubhedha rinogadzira kuburikidza naro, munzira yakatarisana yekuyerera. Mushure menguva yakatarwa yekushanda, mashandiro emibhedha miviri iyi anochinjaniswa, nokudaro achibvumira kuti okisijeni igare ichipiwa nepombi. Ikoku kunozivikanwa sokunyorovesa kwokudzvinyirira. Oxygen gasi iri kuwedzera kuwanikwa neaya asiri-cryogenic matekinoroji onawo inoenderana vacuum swing adsorption.
