Mumaindasitiri, jenareta yenitrogen inoshandiswa zvakanyanya muindasitiri yemafuta, gasi rechisikigo, simbi, chikafu, mishonga uye zvemagetsi. Zvigadzirwa zvenitrogen zvejenareta yenitrogen zvinogona kushandiswa segasi rezvishandiso, asiwo sezvinhu zvemaindasitiri uye refrigerant, inova midziyo yeruzhinji inodiwa mukugadzirwa kwemaindasitiri. Maitiro ejenareta yenitrogen akakamurwa kuita mhando nhatu: nzira yekuparadzanisa mhepo inotonhora yakadzika, nzira yekuparadzanisa membrane uye nzira yekuchinja pressure adsorption (PSA).
Nzira yekuparadzanisa mhepo inotonhora yakadzika ndeyekushandisa musimboti wemafuta anofashaira (boiling point) akasiyana eokisijeni nenitrogen mumhepo, uye kugadzirwa kwenitrogen yemvura neoxygen yemvura kuburikidza nemusimboti wekudzvanya, kufiriji uye kunyorovesa tembiricha yakaderera. "Nzira iyi inogona kugadzira nitrogen yemvura neoxygen yemvura ine tembiricha yakaderera, huwandu hwekugadzirwa hwakakura; dambudziko iri ikudyara mari yakawanda, inowanzo shandiswa mukudiwa kwenitrogen neoxygen muindasitiri yesimbi nemakemikari.
Nzira yekuparadzanisa membrane imhepo sezvinhu zvakabikwa, pasi pemamwe mamiriro ekumanikidzwa, uchishandisa okisijeni nenitrogen mumembrane ine mwero wakasiyana wekubvumidzwa kuita kupatsanurwa kweokisijeni nenitrogen?. Nzira iyi ine zvakanakira zvechimiro chiri nyore, hapana vharuvhu yekuchinja, vhoriyamu diki, nezvimwewo, asi nekuda kwekuti zvinhu zvemembrane zvinonyanya kutsamira pane zvinopinzwa kunze kwenyika, mutengo weparizvino unodhura uye mwero wekupinda wakaderera, saka inonyanya kushandiswa kune zvinangwa zvakakosha zvekuyerera kudiki, senge muchina wekugadzira nitrogen unofamba.
Nzira yekusvina pressure adsorption (PSA) imhepo sezvinhu zvakabikwa, carbon molecular seabsorbent, kushandiswa kwepressure adsorption principle, kushandiswa kwecarbon molecular seabsorbent ye oxygen ne nitrogen adsorption uye oxygen ne nitrogen separation method ". Iyi nzira ine hunhu hwekuyerera kuri nyore kwemaitiro, mwero wepamusoro we automation, kushandiswa kwesimba shoma uye kuchena kwakanyanya kwe nitrogen, uye ndiyo tekinoroji inonyanya kushandiswa. Mhepo isati yapinda mushongwe ye adsorption yevanhu, mvura iri mumhepo inofanira kuomeswa kuti ideredze kuputsika kwemvura pa molecular sea uye kuwedzera hupenyu hwebasa re molecular sea. Mumaitiro ekugadzira nitrogen e PSA, shongwe yekuomesa inowanzo shandiswa kubvisa hunyoro mumhepo. Kana shongwe yekuomesa yazara nemvura, shongwe yekuomesa inodzoserwa nemhepo yakaoma kuti shongwe yekuomesa idzoke patsva.
