Umuvuduko wa swing adsorption azote

ikoresha umwuka nkibikoresho fatizo, karubone ya karubone nka adsorbent, ukoresheje ihame ryumuvuduko ukabije wa adsorption, gukoresha amashanyarazi ya karubone kugirango uhitemo adsorb ogisijeni na azote gutandukanya azote na ogisijeni, bakunze kwita azote ya PSA.Ubu buryo nubuhanga bushya bwo gukora azote bwateye imbere byihuse muri za 1970.Ugereranije nuburyo busanzwe bwo gukora azote, bufite ibyiza byo gutembera byoroshye, urwego rwo hejuru rwo kwikora, kubyara gaze byihuse (iminota 15-30), gukoresha ingufu nke, ubuziranenge bwibicuruzwa birashobora guhinduka murwego runini ukurikije ibyo abakoresha bakeneye, gukora no kuyitaho biroroshye, kandi gukora Hamwe nibiranga ibiciro bidahenze kandi bihindagurika cyane, birarushanwa cyane mubikoresho bitanga umusaruro wa azote munsi ya 1000Nm3 / h, kandi biramenyekana cyane kubakoresha azote ntoya.Umusaruro wa azote PSA wabaye ihitamo ryambere kubakoresha uburyo bwa azote buto.

Azote yo mu kirere ya Cryogenic

Umusemburo wa azote ukomoka ku gutandukanya ikirere ni uburyo gakondo bwo gukora azote ifite amateka yimyaka mirongo.Ikoresha umwuka nkibikoresho fatizo, bigasunikwa kandi bigasukurwa, hanyuma bigakoresha guhanahana ubushyuhe kugirango bigabanye umwuka mubi mwuka.Umwuka wo mu kirere ahanini ni uruvange rwa ogisijeni y’amazi na azote yuzuye, ukoresheje ingingo zitandukanye zitetse za ogisijeni y’amazi na azote yuzuye (ku kirere 1, aho gutekera hambere ni -183 ° C, naho iya -196 ° C) , binyuze mugukosora umwuka wamazi, Bitandukanya kugirango ubone azote.Cryogenic yo gutandukanya ikirere ibikoresho bya azote biragoye, bikubiyemo ahantu hanini, ibiciro remezo bihanitse, gushora ibikoresho inshuro imwe, gushora ibikoresho byinshi, gukora gazi gahoro (12-24h), ibisabwa byinshi byo kwishyiriraho, hamwe nigihe kirekire.Ibikoresho byuzuye, kwishyiriraho nibikorwa remezo, ibikoresho biri munsi ya 3500Nm3 / h, igipimo cyishoramari cyigikoresho cya PSA cyerekana kimwe kiri munsi ya 20% -50% ugereranije nicyuma gitandukanya ikirere cya kirogenike.Ibikoresho byo gutunganya azote ya kirogenike ikwirakwiza umusaruro wa azote nini mu nganda, mu gihe umusaruro wa azote wo mu rwego ruto na muto udasanzwe.

Membrane Gutandukanya Umwuka wa Azote

Gukoresha umwuka nkibikoresho fatizo, mubihe bimwe byumuvuduko, gukoresha ogisijeni na azote hamwe nindi myuka ifite imiterere itandukanye muri membrane bifite igipimo cyinjira cyo gutandukanya ogisijeni na azote.Ugereranije nibindi bikoresho bitanga umusaruro wa azote, ifite ibyiza byuburyo bworoshye, ingano ntoya, nta valve ihinduranya, kubungabunga bike, kubyara gaze byihuse (iminota 3), no kwagura ubushobozi.Irakwiriye cyane cyane kubwera bwa azote ≤ 98% byabakoresha azote ntoya na ntoya bafite igiciro cyiza-ku-mikorere.Iyo azote iri hejuru ya 98%, igiciro cyayo kirenga 15% ugereranije na PSA ya azote ya PSA yibisobanuro bimwe.
