Ib chav sib cais cua (ASU)Nws yog ib qho tseem ceeb ntawm kev lag luam kev lag luam uas ua lub luag haujlwm tseem ceeb hauv kev tshem tawm cov khoom tseem ceeb ntawm cov cua, xws li nitrogen, oxygen, thiab argon.Lub hom phiaj ntawm chav sib cais huab cua yog cais cov khoom ntawm cov huab cua, tso cai rau lawv siv ntau yam kev lag luam thiab kev siv.
Cov txheej txheem ntawm kev sib cais huab cua yog qhov tseem ceeb rau ntau yam kev lag luam, nrog rau kev tsim tshuaj lom neeg, kev kho mob, thiab khoom siv hluav taws xob.Peb lub ntsiab ntawm cov cua - nitrogen, oxygen, thiab argon - tag nrho cov tseem ceeb ntawm lawv tus kheej txoj cai thiab muaj ntau yam kev siv.Nitrogen feem ntau yog siv rau hauv kev tsim cov ammonia rau cov chiv, nrog rau hauv kev lag luam zaub mov thiab dej haus rau ntim thiab khaws cia.Cov pa oxygen yog qhov tseem ceeb rau kev kho mob, txiav hlau, thiab vuam, thaum argon yog siv hauv vuam thiab hlau fabrication, nrog rau kev tsim cov khoom siv hluav taws xob.
Cov txheej txheem kev sib cais huab cua suav nrog kev siv ntau yam txuj ci xws li cryogenic distillation, siab viav vias adsorption, thiab membrane sib cais kom cais cov khoom ntawm cov huab cua raws li lawv cov ntsiab lus kub thiab qhov loj me me.Cryogenic distillation yog txoj kev siv ntau tshaj plaws hauv cov huab cua sib cais loj, qhov chaw cua txias thiab liquefied ua ntej muab cais rau hauv nws cov khoom.
Cua cais unitsyog tsim los tsim high-purity nitrogen, oxygen, thiab argon, uas yog ces liquefied los yog compressed rau cia thiab faib.Lub peev xwm los rho tawm cov khoom no los ntawm cov huab cua ntawm ib qho kev lag luam yog qhov tseem ceeb rau kev ua kom tau raws li qhov xav tau ntawm ntau yam kev lag luam thiab ua kom ntseeg tau cov khoom siv hluav taws xob zoo.
Hauv cov ntsiab lus, lub hom phiaj ntawm chav sib cais huab cua yog txhawm rau tshem tawm cov khoom tseem ceeb ntawm huab cua - nitrogen, oxygen, thiab argon - siv rau ntau yam kev lag luam.Los ntawm kev siv cov txheej txheem sib cais qib siab, cov cua sib cais ua lub luag haujlwm tseem ceeb hauv kev muab cov pa roj purity siab uas yog qhov tseem ceeb rau ntau yam kev lag luam thiab cov khoom lag luam.
