Mu rwego rwo gutandukanya gaze no kweza, hamwe no gushimangira kurengera ibidukikije, hamwe n’ibisabwa muri iki gihe kutabogama kwa karubone, CO2gufata, kwinjiza imyuka yangiza, no kugabanya ibyuka bihumanya byabaye ibibazo byingenzi. Muri icyo gihe, hamwe no guhindura no kuzamura inganda zacu, inganda za gaze zifite isuku ziragenda ziyongera. Gutandukanya gazi no kweza tekinoroji harimo kugabanya ubushyuhe buke, adsorption no gukwirakwizwa. Tuzamenyekanisha inzira ebyiri zisanzwe kandi zisa na adsorption, arizo igitutu swing adsorption (PSA) hamwe nubushyuhe bwubushyuhe butandukanye (TSA).
Ihame nyamukuru rya pression swing adsorption (PSA) rishingiye kubitandukanya mubiranga adsorption yibigize gaze mubikoresho bikomeye nibiranga ihinduka rya adsorption ihindagurika hamwe nigitutu, ukoresheje ihinduka ryumuvuduko wigihe kugirango urangize gutandukanya gaze no kwezwa. Impinduka-yubushyuhe bwa adsorption (TSA) nayo yifashisha itandukaniro ryimikorere ya adsorption yibigize gaze kubikoresho bikomeye, ariko itandukaniro nuko ubushobozi bwa adsorption buzagira ingaruka kumihindagurikire yubushyuhe, no gukoresha ibihe bihindagurika-ubushyuhe kugirango bigere kubitandukanya na gaze no kwezwa.
Umuvuduko ukabije wa adsorption ukoreshwa cyane mugufata karubone, hydrogène na ogisijeni, gutandukanya azote methyl, gutandukanya ikirere, gukuraho NOx nizindi nzego. Kuberako igitutu gishobora guhinduka vuba, uruziga rwumuvuduko wa swing adsorption muri rusange ni mugufi, rushobora kuzuza uruziga muminota mike. Kandi ubushyuhe bwubushyuhe bwa adsorption bukoreshwa cyane cyane mugufata karubone, kweza VOC, kumisha gaze hamwe nindi mirima, bigarukira ku gipimo cyo kohereza ubushyuhe bwa sisitemu, igihe cyo gushyushya no gukonjesha ni kirekire, ubushyuhe bwo guhinduranya ubushyuhe buzaba burebure, rimwe na rimwe bushobora kugera kuri byinshi kurenza amasaha icumi, none nigute wagera kubushyuhe bwihuse no gukonjesha nabyo ni kimwe mubyerekezo byubushakashatsi bwubushyuhe bwa adsorption. Bitewe no gutandukana mugihe cyibikorwa byigihe, kugirango bikoreshwe muburyo bukomeza, PSA akenshi isaba iminara myinshi murwego rumwe, kandi iminara 4-8 ni imibare isanzwe (igihe kigufi cyibikorwa, nimibare ibangikanye). Nkigihe cyigihe cyubushyuhe bwo guhinduka adsorption ni ndende, inkingi ebyiri zikoreshwa mubusanzwe ubushyuhe bwa adsorption.
Byakoreshejwe cyane adsorbents kubushyuhe bwubushyuhe bwa adsorption hamwe nigitutu cya swing adsorption ni sikeri ya molekile, ikora karubone, silika gel, alumina, nibindi, kubera ubuso bunini bwihariye, birakenewe guhitamo adsorbent ikwiranye nibikenewe. sisitemu yo gutandukana. Umuvuduko ukabije wa adsorption hamwe na desorption yumuvuduko wikirere nibyo biranga igitutu swing adsorption. Umuvuduko wo gukanda adsorption urashobora kugera kuri MPa nyinshi. Ubushyuhe bwo gukora bwubushyuhe butandukanye adsorption hafi yubushyuhe bwicyumba, kandi ubushyuhe bwo gushyushya desorption bushobora kugera kuri 150 ℃.
Mu rwego rwo kunoza imikorere no kugabanya gukoresha ingufu, vacuum pressure swing adsorption (VPSA) hamwe na tekinoroji yubushyuhe bwa vacuum adsorption (TVSA) ikomoka kuri PSA na PSA. Iyi nzira iraruhije kandi ihenze, bigatuma ikenerwa gutunganya gazi nini. Vacuum swing adsorption ni adsorption kumuvuduko wikirere hamwe na desorption mukuvoma vacuum. Mu buryo nk'ubwo, vacuumizing mugihe cya desorption irashobora kandi kugabanya ubushyuhe bwa desorption no kunoza imikorere ya desorption, bizafasha mugukoresha ubushyuhe bwo murwego rwo hasi mugihe cya vacuum variable ubushyuhe bwa adsorption.
