Ibikoresho byo gukora azote biboneka mugutandukanya umwuka na azote nibikoresho fatizo ukoresheje umwuka nkibikoresho fatizo.
Hariho ubwoko butatu bwa azote mu nganda:
Azote yo mu kirere itandukanya azote
Cryogenic yo mu kirere itandukanya azote ni uburyo bwa gakondo bwa azote bumaze imyaka mirongo ishize.Ikoresha umwuka nkibikoresho fatizo, irahagarikwa, irasukurwa, hanyuma ikoresha guhanahana ubushyuhe kugirango ihumeke umwuka mwuka.Umwuka w’amazi ni uruvange rwa ogisijeni y’amazi na azote yuzuye, ifite ingingo zitandukanye zitetse za ogisijeni y’amazi na azote yuzuye (aho gutekera hambere ni -183 ° C kuri atm 1, naho iya -196 ° C) , no gusibanganya binyuze mu kirere cyamazi Bitandukanya kugirango ubone azote.Ibikoresho byo mu kirere bya kirogenike bitandukanya ibikoresho bya azote biragoye, bikubiyemo ahantu hanini, bifite igiciro kinini cy’igishoro, kandi bifite ishoramari ryinshi mu bikoresho, igiciro kinini cyo gukora, umusaruro wa gaze muke (amasaha 12 kugeza 24), ibisabwa byo kwishyiriraho byinshi hamwe nigihe kirekire.Ibikoresho byuzuye, kwishyiriraho nibikorwa remezo, ibikoresho biri munsi ya 3500Nm3 / h, ingano yishoramari ryibikoresho bya PSA mubisobanuro bimwe ni 20% ~ 50% munsi yikigo gitandukanya ikirere.Uruganda rwa azote rutandukanya ikirere cya azote ikwiranye n’inganda nini nini zo mu nganda, mu gihe umusaruro wa azote wo hagati na muto ntubukungu.

Ile Azote ya azote
Uburyo umwuka ukoreshwa nkibikoresho fatizo, icyuma cya karubone ikoreshwa nka adsorbent, hakoreshwa ihame ryumuvuduko ukabije wa adsorption, hamwe no gutoranya guhitamo ogisijeni na azote ukoresheje icyuma cya karubone ikoreshwa mu gutandukanya azote na ogisijeni. muri rusange byitwa umusaruro wa azote wa PSA.Ubu buryo ni tekinoroji nshya itanga azote yatejwe imbere byihuse mu myaka ya za 70.Ugereranije nuburyo gakondo bwo gukora azote, ifite inzira yoroshye, murwego rwo hejuru rwo kwikora, kubyara gazi yihuse (iminota 15 kugeza 30), gukoresha ingufu nke, ubuziranenge bwibicuruzwa birashobora guhinduka ukurikije ibyo abakoresha bakeneye muburyo butandukanye, gukora byoroshye no kubungabunga , imikorere Igiciro gito kandi gihuza cyane nigikoresho, nuko irushanwa mubikoresho bitanga azote munsi ya 1000Nm3 / h.Birarushijeho gukundwa mubakoresha nitorojeni ntoya.Azote ya PSA yabaye ihitamo ryambere kubakoresha azote nto na nto.buryo.

◆ Membrane itandukanya ikirere azote
Umwuka ukoreshwa nkibikoresho fatizo, kandi mubihe bitandukanye byumuvuduko, imyuka yibintu bitandukanye nka ogisijeni na azote bifite igipimo cyinshi cyo kwinjira muri membrane kugirango gitandukanye ogisijeni na azote.Ugereranije nibindi bikoresho byo gukora azote, ifite ibyiza byuburyo bworoshye, ingano ntoya, nta valve ihinduranya, kubungabunga bike, kubyara gaze byihuse (iminota 3), kongera ubushobozi bworoshye, nibindi Birakwiriye cyane cyane kubwera bwa azote ≤ 98 % by'abakoresha iciriritse na batoya bafite igiciro cyiza / igipimo cyiza.Iyo ubuziranenge bwa azote buri hejuru ya 98%, burenga 15% kurenza ibikoresho byo gukora azote ya PSA byerekana bimwe.
