Me Cryogenic Cua Sib cais

Cov tshuab hluav taws xob sib cais me me tau siv dav hauv nruab nrab mus rau kev ua haujlwm loj thiab siv cov tshuab cua cryogenic sib cais los tsim cov nitrogen, oxygen thiab argon li roj lossis kua tso tawm. Rau zus tau tej cov ultrapure oxygen thiab nitrogen, me me cryogenic cua sib cais txoj kev raug pom zoo. Cov thev naus laus zis no yog qhov kev xaiv pheej yig tshaj plaws rau cov chaw tsim khoom siab thiab siv rau hauv txhua txoj haujlwm tsim cov khoom lag luam roj liquefied. Qhov yuav tsum tau muaj cov pa roj thiab cov kua dej ntws tawm, cov khoom purity thiab kev xa khoom siab cuam tshuam rau qhov nyuaj ntawm cov txheej txheem cryogenic cua sib cais, nrog rau lub cev loj ntawm cov khoom siv thiab lub zog yuav tsum tau ua haujlwm.

Cov kauj ruam ntxaws ntxaws ntawm cov txheej txheem cryogenic huab cua sib cais

1. Cua Compression: Cov huab cua nyob ib puag ncig yog compressed siv ntau theem turbo compressor nrog intercooler thiab plua plav hais tawm nrog cov tshuab lim.
2. Cua txias thiab purification: Siv cov dej txias kom txias cua thiab tshem tawm cov khoom soluble. Cov dej txias yog txias los ntawm lub evaporative txias thiab adsorbers yog siv los tshem tawm carbon dioxide, dej vapor thiab hydrocarbons.
3. Tsawg-kub kub pauv: Counterflow heat exchanger cools huab cua mus ze liquefaction kub thiab siv nitrogen tso pa roj ua ntej txias.
4. Kev tsim khoom txias thiab cov khoom lag luam hauv compression: Cov cua sab kwj yog compressed siv lub tshuab cua compressor, txias ntau lawm thiab nthuav dav tau tiav los ntawm kev nthuav dav turbine, thiab cov kwj sab yog ntxiv liquefied hauv cov kua cais. Lub high-pressure heat exchanger vaporizes cov pa oxygen thiab nitrogen cov khoom thiab heats lawv mus rau ambient kub.
5. Cua cryogenic distillation: Cov cua txias liquefied tau muab cais ua cov kua oxygen nplua nuj thiab cov nitrogen ntshiab hauv cov kab siab. Sab saum toj condenser liquefies nitrogen thiab hauv qab reboiler txhim kho oxygen purity.
6. Argon cryogenic rectification: Ib kem ntxiv cais argon, sab kwj yog cais tawm ntawm oxygen nyob rau hauv crude argon kem, cov kua oxygen yog refluxed mus rau qis-siab kem, thiab nitrogen yog ntxiv tshem tawm nyob rau hauv lub ntshiab argon kem.
