Qhov nooxygen nitrogen kua tsob nrojnta ua haujlwm ntev - lub sijhawm ua haujlwm thiab cov yam ntxwv qis qis.

Cov khoom siv tseem ceeb ntawm cov txheej txheem nooxygen nitrogen kua tsob nroj, xws li cov kab distillation, lub ntsiab cua kub exchanger thiab lub ntsiab txias txias, yog tag nrho cov khoom siv hlau zoo li qub. Nyob rau hauv ib puag ncig qis - qhov kub thiab txias, cov khoom ua haujlwm ruaj khov thiab tsis muaj teeb meem hnav lossis kev laus ntawm cov khoom txav.

Ntev npaum li lub hauv ntej -kawg cua purification system (molecular sieve) ntawm qhov nooxygen nitrogen kua tsob nrojua haujlwm tau zoo, nws txoj kev sib cais yuav tsis pom qhov poob qis hauv ntau xyoo lawm. Qhov no muaj qhov tseem ceeb ntev -lub sij hawm kev ua tau zoo piv nrog PSA / membrane sib cais tshuab uas tso siab rau adsorbents lossis cov ntaub ntawv membrane.
