Ubwoko bwa azote burimo umuvuduko ukabije wa adsorption, gutandukana kwa membrane no gutandukanya ikirere.Amashanyarazi ya azote ni ibikoresho bya azote byakozwe kandi bikozwe ukurikije tekinoroji ya adsorption.Imashini ya azote ikoresha ibyuma bya karubone byujuje ubuziranenge bitumizwa mu mahanga nka adsorbent kandi ikoresha ihame ryubushyuhe bwicyumba cya swing adsorption kugirango itandukane umwuka kugirango itange azote nziza.Mubisanzwe, iminara ibiri ya adsorption ihujwe murwego rumwe, kandi PLC itumizwa mu mahanga igenzura imikorere yikora ya valve ya pneumatike yatumijwe kugirango ihindure ubundi buryo bwo guhinduranya ingufu za adsorption hamwe na decompression kugirango irangize azote na ogisijeni ikenewe kandi ibone azote ikenewe cyane.
Uburyo bwa mbere ni umusaruro wa azote ukoresheje cryogenic
Ubu buryo bwabanje gukanda no gukonjesha umwuka, hanyuma bigahumeka umwuka.Ukoresheje ingingo zitandukanye zitetse za ogisijeni hamwe na azote, gaze hamwe na flux ihuza kumurongo wa distillation ya misa hamwe no guhanahana ubushyuhe.Umwuka wa ogisijeni ufite aho utekera cyane uhora wunamye uva mu mwuka ukajya mu mazi, kandi azote ifite aho itetse ikomeza kwimurirwa mu cyuka, ku buryo ibirimo azote iri mu cyuka kizamuka bikomeza kwiyongera, mu gihe ibirimo ogisijeni biri mu ruzi. amazi ari hejuru kandi hejuru.Kubwibyo, ogisijeni na azote bitandukanijwe kugirango bibone azote cyangwa ogisijeni.Ubu buryo bukorwa ku bushyuhe buri munsi ya 120K, bityo bita gutandukanya ikirere.
Iya kabiri ni ugukoresha igitutu swing adsorption kugirango itange azote
Uburyo bwa pression swing adsorption nuburyo bwo guhitamo adsorb ogisijeni hamwe na azote mu kirere binyuze muri adsorbent, no gutandukanya umwuka kugirango ubone azote.Iyo umwuka uhagaritse kandi ukanyura murwego rwa adsorption umunara wa adsorption, molekile ya ogisijeni ikunzwe cyane, kandi molekile ya azote iguma mugice cya gaze kugirango ibe azote.Iyo adsorption igeze kuringaniza, molekile ya ogisijeni yamamajwe hejuru ya sikeli ya molekile ikurwaho na decompression kugirango igarure ubushobozi bwa adsorption ya sikile ya molekile, ni ukuvuga isesengura rya adsorbent.Kugirango dukomeze gutanga azote, igice gikunze kuba gifite iminara ibiri cyangwa myinshi ya adsorption, imwe ya adsorption indi yo gusesengura, hanyuma igahinduka kugirango ikoreshwe mugihe gikwiye.
Uburyo bwa gatatu nugukora azote mugutandukanya membrane
Uburyo bwo gutandukanya Membrane ni ugutandukanya gaze ikungahaye kuri azote na gaze ivanze ukoresheje uburyo bwo guhitamo ibintu bya polymerisiyumu.Ibikoresho byiza bya firime bigomba kugira amahitamo menshi kandi byoroshye.Kugirango ubone inzira yubukungu, birasabwa cyane polymer itandukanya membrane, bityo ikeneye inkunga.Ibirwanisho byo gutobora ibirwanisho mubisanzwe ni ibirwanisho bitobora ibirwanisho hamwe na fibre fibre fibre.Muri ubu buryo, niba umusaruro wa gaze ari munini, ubuso bwa firime busabwa ni bunini cyane kandi igiciro cya firime kiri hejuru.Uburyo bwo gutandukanya Membrane bufite ibikoresho byoroshye nibikorwa byoroshye, ariko ntibikoreshwa cyane mubikorwa.
Kurangiza, ibyavuzwe haruguru nibyingenzi muburyo butandukanye bwo gukora azote.Gutandukanya umwuka wa Cryogenic ntibishobora kubyara azote gusa, ahubwo binatanga azote yuzuye, ishobora kubikwa mububiko bwa azote.Imikorere yinzira ya azote ya azote muri rusange irenze umwaka, kubwibyo ibikoresho byo guhagarara ntibisanzwe bifatwa nkibikorwa bya azote.Ihame ry'umusaruro wa azote ukoresheje gutandukanya ikirere ni uko umwuka winjira muri polymer membrane nyuma yo kuyungurura na compressor.Bitewe nubushobozi butandukanye bwo gukwirakwiza no gukwirakwiza imyuka ya gaze zitandukanye muri membrane, igipimo cyo kwinjiza ugereranije na gaze zitandukanye.Iyo ubuziranenge bwa azote burenze 98%, igiciro kirenze 15% ugereranije na PSA ya azote ya PSA yerekana ibintu bimwe.
