CUA SATIONATION NYOB(Asus) yog cov khoom siv tseem ceeb ntawm cov khoom siv los cais cov khoom siv ntawm huab cua, feem ntau nitrogen thiab qee zaum argon thiab lwm yam kev sib cav tsis tshua muaj pa. Lub hauv paus ntsiab lus ntawm kev sib cais huab cua yog nyob ntawm huab cua yog kev sib xyaw ntawm cov roj av, nrog nitrogen thiab oxygen yog ob lub ntsiab. Cov qauv kev sib cais feem ntau ntawm cov pa sib cais yog feem ntau distillation, uas siv kom zoo dua ntawm cov ntsiab lus sib txawv ntawm cov khoom sib cais ntawm lawv.
Fortalal distillation ua haujlwm ntawm lub hauv paus ntsiab lus uas thaum muaj kev sib xyaw ua pa tawm rau qhov sib txawv heev, cov khoom sib txawv yuav ua kom kub hnyiab, tso cai rau lawv kev sib cais. Nyob rau hauv cov ntaub ntawv ntawm huab cua sib cais, cov txheej txheem pib los ntawm compressing cov cua rau siab kom siab siab thiab tom qab ntawd txias nws. Raws li huab cua txias, nws yog dhau los ntawm cov kab ntawv ntawm cov distillation uas cov sib txawv me me ntawm kev sib pauv kub. Qhov no tso cai rau kev sib cais ntawm cov nitrogen, oxygen, thiab lwm yam roj cua nyob hauv huab cua.
Cov txheej txheem sib cais huab cuakoom nrog ntau kauj ruam ntau cov kauj ruam, suav nrog cov compression, purification, txias, thiab sib cais. Lub tshuab nqus pa taws yog thawj limhiv kom tshem tawm cov impurities thiab noo noo ua ntej tau txias kom txias heev. Cov cua txias txias yog tom qab dhau los ntawm cov kab distillation uas kev sib cais ntawm cov khoom siv. Cov khoom lag luam uas tau sau thiab khaws cia rau ntau cov ntawv thov ntau yam.
Cov koog sib cais huab cua yog qhov tseem ceeb hauv kev lag luam tshuaj, steel ntau lawm, thiab hluav taws xob, qhov twg cov roj sib cais, cov khoom siv hluav taws xob uas siv rau ntau cov ntawv thov. Nitrogen, piv txwv li, yog siv hauv kev lag luam khoom noj khoom haus rau kev tsim khoom lag luam semiconductors, thiab hauv cov roj thiab roj kev lag luam rau inerting thiab pam. Oxygen, ntawm qhov tod tes, yog siv hauv kev siv tshuaj kho mob, hlau txiav thiab vuam, thiab hauv kev tsim cov tshuaj thiab iav.
Hauv kev xaus, kev sib cais huab cua ua lub luag haujlwm tseem ceeb hauv kev lag luam tseem ceeb hauv kev sib raug zoo los ntawm kev sib cais ntawm cov huab cua siv lub hauv paus ntawm cov fractional distillation. Tus txheej txheem no tso cai rau kev tsim cov nitrogen, oxygen, thiab lwm cov roj uas tseem ceeb uas tseem ceeb rau cov ntawv thov muaj ntau.
