Ibicuruzwa biranga PSA ya azote

Iterambere ryihuse ry’inganda, azote yakoreshejwe cyane mu bijyanye n’imiti, ibikoresho bya elegitoroniki, metallurgie, ibiryo, imashini, n’ibindi. Ibikenerwa na azote mu gihugu cyanjye biriyongera ku gipimo kirenga 8% buri mwaka.Azote idakora mu buryo bwa shimi, kandi ntigikora cyane mubihe bisanzwe, kandi ntabwo byoroshye kubyitwaramo nibindi bintu.Niyo mpamvu, azote ikoreshwa cyane mu gukingira gaze no gufunga gaze mu nganda z’ibyuma, inganda za elegitoroniki, n’inganda zikora imiti.Muri rusange, ubuziranenge bwa gaze ikingira ni 99,99%, kandi bimwe bisaba azote nziza cyane ya 99,998%.Amazi ya azote ni isoko yubukonje bworoshye, kandi irakoreshwa cyane mubikorwa byibiribwa, inganda zubuvuzi, no kubika amasohoro yubuhinzi.Mu musaruro wa ammoniya yubukorikori mu nganda zifumbire mvaruganda, niba gaze yibikoresho bya ammoniya ya sintetike - hydrogène na azote ivanze na gaze ya azote yogejwe kandi igatunganywa na azote yuzuye yuzuye, ibirimo gaze ya inert irashobora kuba nto cyane, kandi nibirimo sulfure monoxide na ogisijeni ntibirenza 20 ppm.

Azote nziza ntishobora gukururwa biturutse kuri kamere, kandi gutandukanya ikirere bikoreshwa cyane.Uburyo bwo gutandukanya ikirere burimo: uburyo bwa cryogenic, igitutu swing adsorption uburyo (PSA), uburyo bwo gutandukanya membrane.

Intangiriro kubikorwa nibikoresho bya PSA ya azote

Intangiriro kubikorwa bigenda

Umwuka winjira mu kirere nyuma yo gukuraho ivumbi n’imyanda ikoresheje akayunguruzo ko mu kirere, kandi bigabanywa n’umuvuduko ukenewe.Nyuma yo kwangirika gukabije, kuvomera amazi, no kuvanaho ivumbi, umwuka usukuye urasohoka kugirango harebwe imikoreshereze ya molekile muminara ya adsorption.ubuzima.

Hano hari iminara ibiri ya adsorption ifite ibikoresho bya karubone.Iyo umunara umwe urimo gukora, undi munara ucibwa intege na desorption.Umwuka mwiza winjira mu munara wa adsorption ukora, kandi iyo unyuze mu cyuma cya molekile, ogisijeni, dioxyde de carbone n'amazi byamamazwa na yo.Gazi itemba isohoka ni azote hamwe na argon na ogisijeni.

Undi munara (umunara wa desorption) utandukanya ogisijeni ya adsorbed, karuboni ya dioxyde de carbone hamwe namazi nu byobo bya molekile ya molekile ikabisohora mu kirere.Muri ubu buryo, iminara yombi ikorwa murwego rwo kurangiza azote na ogisijeni no gukomeza azote.Ubuziranenge bwa azote ikorwa nigitutu cyingutu (_bian4 ya1) adsorption ni 95% -99.9%.Niba azote isukuye cyane, ibikoresho byo kweza azote bigomba kongerwamo.

95% -99.9% biva muri azote biva mumashanyarazi ya azote itanga ingufu za azote yinjira mubikoresho byoza azote, kandi mugihe kimwe cya hydrogène ikwiye kongerwaho binyuze mumashanyarazi, hanyuma hydrogène hamwe na ogisijeni ikurikirana muri azote bigira uruhare runini muri umunara wa deoxygene wibikoresho byo kweza kugirango ukureho ogisijeni ihita ikonjeshwa na kondereseri yamazi, itandukanya amazi-yamashanyarazi ikamwa amazi, hanyuma ikumishwa cyane nuwumisha (iminara ibiri yumisha ya adsorption ikoreshwa muburyo butandukanye: imwe ikoreshwa muri adsorption na kumisha kugirango ukureho amazi, andi arashyuha kugirango desorption hamwe namazi kugirango abone azote ifite isuku nyinshi.Ubuziranenge bwa azote burashobora kugera kuri 99,9995%. Kugeza ubu, ubushobozi bunini bwo gukora ingufu za azote ya adsorption azote ku isi ni 3000m3n / h.
