Ibihingwa bya azote bifite isuku byabaye ingirakamaro mu nganda nyinshi nk'imiti, ibikoresho bya elegitoroniki, hamwe n'ubuvuzi. Azote ni ikintu cy'ingenzi muri izo nganda hafi ya zose, kandi ubuziranenge bwayo n'ubwiza bwayo bigira uruhare runini mu kwemeza ibicuruzwa byanyuma. Kubwibyo, gutanga azote nziza yo mu rwego rwo hejuru ni ngombwa cyane.
Umuvuduko ukabije wa adsorption (PSA) nubuhanga bushobora gukoreshwa mugusukura azote ukuraho ogisijeni nindi myanda. PSA ishingiye ku ihame rya gaz adsorption kubintu bikomeye bya adsorbent. Amatangazo ya adsorbent yatoranijwe ashingiye kubushobozi bwayo bwo kwamamaza molekile ya gaze yinyungu, mugihe yemerera izindi myuka kunyuramo.
Mu gihingwa cya azote gifite isuku nyinshi, tekinoroji ya PSA irashobora gukoreshwa mu gukora azote cyangwa ogisijeni mu kugenzura adsorption na desorption ya molekile ya gaze. Inzira ikubiyemo guhagarika umwuka kumuvuduko wihariye no kuyinyuza muburiri bwibikoresho bya adsorbent. Ibikoresho bya adsorbent bizatanga ogisijeni nindi myanda, mugihe azote inyura muburiri igakusanyirizwa mububiko.
Ibikoresho bya adsorbent birashobora kuvugururwa mukurekura umuvuduko, utera molekile ya gaze kugabanuka kubintu. Gazi yangiritse noneho inyuzwa muri sisitemu, kandi adsorbent yiteguye kwamamaza iyindi nziga ya molekile ya gaze.
Imwe mu nyungu zambere zo gukoresha ikoranabuhanga rya PSA mubihingwa bya azote bifite isuku ryinshi nigiciro cyacyo. Ikoranabuhanga rya PSA rirakora cyane kandi ntirisaba ibikoresho bigoye cyangwa abakozi kabuhariwe gukora. Byongeye kandi, ifite amafaranga make yo gukora, kuko idasaba isoko yingufu zose zitari umwuka uhumeka.
Iyindi nyungu ni byinshi. Ikoranabuhanga rya PSA rirashobora kubyara azote na ogisijeni, bitewe nibikoresho bya adsorbent byatoranijwe. Umwuka ukungahaye kuri Oxygene urashobora gukoreshwa mu nganda nyinshi nko kuvura no gusudira, aho usanga umwuka wa ogisijeni mwinshi.
Ariko, kubyara azote cyangwa ogisijeni nziza cyane binyuze muri tekinoroji ya PSA bisaba guhitamo neza ibikoresho bya adsorbent. Ibikoresho bya adsorbent bigomba kuba bifite amahitamo menshi kuri molekile ya gaze yinyungu kandi bigomba kuba bikwiranye nimikorere yuruganda rwa azote nziza. Byongeye kandi, ingano nuburyo bwibikoresho bya adsorbent bigomba kuba byiza kugirango bigabanye umuvuduko ukabije kandi byemeze neza.
Mu gusoza, tekinoroji ya PSA nuburyo bukora neza kandi buhendutse bwo gukora azote nziza cyangwa ogisijeni mwinshi mubihingwa bya azote. Itanga ibyiza byinshi, harimo guhinduranya hamwe nigiciro gito cyo gukora. Ariko rero, guhitamo neza ibikoresho bya adsorbent nibyingenzi kugirango hamenyekane isuku nubuziranenge bwa azote cyangwa ogisijeni yakozwe. Hamwe ninyungu nyinshi, tekinoroji ya PSA nuburyo bukurura inganda zisaba gutanga azote nziza, yizewe.
