Txhua qhov kev kho mob oxygen yog muab rho tawm los ntawm huab cua atmospheric. Cua muaj kwv yees li 21% oxygen, 78% nitrogen, thiab 1% tsawg gases xws li argon thiab carbon dioxide. Lub hauv paus ntawm kev tsim cov pa oxygen yog rho tawm cov pa tawm ntawm huab cua thiab ua kom huv si kom tau raws li cov qauv kev kho mob purity (Ntau dua lossis sib npaug li 90%). Muaj ob hom kev sib cais huab cua: cryogenic sib cais thiab siab viav vias adsorption (PSA) nrog molecular sieves.
Cov ntsiab cai ntawm Cryogenic Separation
Cov txheej txheem no siv cua ua cov khoom siv raw. Cov huab cua yog compressed, purified thiab liquefied ntawm tshav kub exchanger. Liquefied cua feem ntau yog sib xyaw ua kua oxygen thiab kua nitrogen. Leveraging lawv cov ntsiab lus boiling sib txawv, oxygen thiab nitrogen yog sib cais los ntawm rectification. Cov pa uas ua los ntawm kev sib cais cryogenic yog muaj cov pa oxygen, uas yuav tsum tau ua kom huv ntxiv, ua kom tsis muaj menyuam thiab lwm yam txheej txheem ua ntej nws tuaj yeem siv los ua cov pa kho mob.

Lub hauv paus ntsiab lus ntawm Siab Swing Adsorption (PSA) nrog Molecular Sieves
Nyob rau hauv chav tsev kub, compressed cua yog lim thiab purified. Cov pa oxygen tshwj xeeb- tsim cov molecular sieves yog siv los xaiv adsorb nitrogen hauv huab cua, ua kom siab - purity oxygen (93% ± 3). PSA sawv cev rau Siab Swing Adsorption.
Qhov txawv ntawm Cryogenic Separation thiab PSA
Ob txoj kev sib txawv tshaj plaws hauv cov qauv kev ua haujlwm thiab cov khoom siv. Cov txheej txheem cryogenic liquefies cua ntawm qhov tsis tshua muaj kub thiab cais cov pa roj los ntawm kev hloov kho raws li qhov sib txawv ntawm qhov kub. Nws ua kua oxygen, thiab cov khoom tso tawm thawj zaug yog cov pa oxygen uas xav tau kev lim dej ntxiv rau kev siv kho mob. Los ntawm qhov sib txawv, PSA ua haujlwm ntawm chav tsev kub. Nws tso siab rau molecular sieves rau adsorb nitrogen thiab tsim cov pa oxygen uas tuaj yeem siv ncaj qha rau kev kho mob.
Los ntawm cov saw saw kev pom, kev sib cais cryogenic cia siab rau sab nraud xa tawm ntawm cov kua oxygen. Ib qho kev cuam tshuam rau cov saw hlau yuav ua rau muaj kev puas tsuaj rau cov pa oxygen hauv tsev kho mob. PSA ua rau ntawm - qhov chaw tsim cov pa oxygen, uas yog ywj siab, tswj tau thiab tsis muaj kev cuam tshuam sab nraud.
Nyob rau hauv cov nqe lus ntawm kev nyab xeeb, kua oxygen tso tsheb hlau luam rau cov tshuab cryogenic muaj kev pheej hmoo ntawm kev xau. Ib liter ntawm kua oxygen vaporizes rau hauv gaseous oxygen nrog 800 npaug ntawm nws thawj ntim. Ib qho dej xau yuav tsim cov pa oxygen loj- cov cheeb tsam ntxiv, uas tuaj yeem ua rau hluav taws tau yooj yim thaum raug hluav taws kub. Tsis tas li ntawd, hydrocarbons zoo li acetylene txuas ntxiv mus rau hauv lub thawv txias txias ntawm cov khoom siv cryogenic, ua rau muaj kev phom sij tawg. PSA khiav ntawm qhov kub thiab txias tsis tshua muaj siab, thiab nws cov molecular sieves tuaj yeem adsorb feem ntau acetylene thiab hydrocarbons, xa cov txiaj ntsig kev nyab xeeb.
