Nitrogen tshuab thiab ntau cov khoom sib cais huab cua ntau lawm tuam txhab uas muag yuav tsum tau ua raws li xws li lub khw khw kev loj hlob txoj cai, tab sis lub davhlau ya nyob twg yeej yog lub tuam txhab nitrogen tshuab kom yeej kev ntseeg siab. Nws yog ib qho tsim nyog los tsim kev lag luam raws li cov cai ntawm kev ua lag luam, pib los ntawm kev tshawb fawb pom, kev txhim kho ntawm kev ua lag luam tsis muaj teeb meem.
Raws li kev tshawb fawb, 4% ntawm cov khoom lag luam tshiab pib ua tsis tiav vim lawv xaiv lub lag luam tsis raug. Qee lub tuam txhab ua si loj thiab ua si me, tsis hais lawv lub zog. Lwm tus ua yam tsis saib xyuas thiab saib deb dhau qhov tam sim ntawd. Tom qab tag nrho, lawv tsim cov khw muag khoom tsis yog los ntawm lub tuam txhab lub tswv yim yuav khoom, los yog los ntawm cov khw muag khoom tiag tiag, tab sis kom maj, ntaus qhov twg yog qhov twg. Tshwj xeeb tshaj yog thaum lub sij hawm tso tawm cov khoom tshiab, lub tuam txhab xav tias kev ua lag luam tuaj yeem ua tau txhua qhov chaw, uas yog qhov yuam kev tiag tiag kom paub. Thaum lub khw tsis muaj dab tsi, kev xaiv yuav yog qhov tseem ceeb tshwj xeeb.
Tam sim no, kev lag luam hauv tsev tsuas yog siv cov qib qis carbon molecular sieve, qhov kev thov txhua xyoo yog ntau tshaj 2000 tons, nrog rau kev txhim kho txuas ntxiv ntawm Tuam Tshoj txoj kev lag luam, tshwj xeeb tshaj yog kev nthuav dav ntawm kev lag luam kev npaj, theem ntawm kev thov rau carbon molecular sieve yuav nce xyoo los ntawm xyoo. Tshwj xeeb tshaj yog nyob rau xyoo tas los no, lub xeev tseem ceeb heev rau kev nyab xeeb ntawm cov mines, yuam cov thee mines los nruab cov tshuab nitrogen, thiab txuas ntxiv nthuav cov kev thov hauv tsev rau carbon molecular sieve.
Txij li xyoo 2000, qhov nruab nrab txhua xyoo kev loj hlob tau ntau dua 80 feem pua. Kev ua lag luam hauv tsev yog qhov kaj heev. Nrog rau kev ua haujlwm tsis tu ncua ntawm lub siab viav vias adsorption kev txawj ntse, kev siv tshuab nitrogen ntau dua thiab dav, kev xav tau thoob ntiaj teb rau carbon molecular sieve tseem loj hlob, qhov kev thov ntawm cov teb chaws tsim kho xws li Europe thiab Tebchaws Meskas tau nce zuj zus txhua xyoo, Nyob rau hauv xyoo tas los no, qhov kev thov ntawm cov teb chaws tau hloov pauv nrog txhua hnub tshiab, nce ntawm ob npaug ntawm txhua xyoo, kev kwv yees khaws cia, Hauv xyoo 2009, tag nrho cov kev xav tau ntawm carbon molecular sieve hauv ntiaj teb yog ntau dua 100 lab tons.
Raws li kev soj ntsuam ntawm cov kws tshaj lij thoob ntiaj teb thiab hauv tsev, cov pa roj carbon molecular sieve kev ua haujlwm zoo li kev txhim kho hauv qab no: Ua ntej, nrog kev nthuav dav ntxiv ntawm kev siv lub tshuab nqus pa nqus cua nitrogen, qhov xav tau ntawm carbon molecular sieve tseem nce ntxiv, uas yuav ntxiv mus. txhawb txoj kev loj hlob ntawm txoj hauj lwm, nyob rau hauv ob peb xyoos tom ntej no, txoj hauj lwm no yuav dhau los ua neeg paub zoo los ntawm kev ua haujlwm tsis tshua muaj.
Thib ob, nrog kev nce qib ntawm qhov tob ntawm kev siv, qhov kev xav tau ntawm cov khoom siv hluav taws xob ntau dua thiab lwm lub hom phiaj kev txhim kho ntawm cov khoom lag luam ua tiav yuav yog tus qauv dav dav ntawm txoj haujlwm no yav tom ntej.
Thib peb, vim tias carbon molecular sieve yog lub hauv paus tseem ceeb ntawm lub siab viav vias adsorption nitrogen tshuab, tus nqi them rau ntau tshaj 70% ntawm tag nrho cov cuab yeej, yog li ntawd, txo tus nqi yuav yog ib qho tseem ceeb los txhawb txoj kev loj hlob ntawm txoj haujlwm no. Nyob rau lub sijhawm tom ntej, cov tuam txhab tseem yuav tshawb nrhiav kev xaiv cov khoom siv tshiab thiab cov txheej txheem tshiab, thiab sib zog ua kom mus txog qib siab nrog cov nqi qis.
Nitrogen as a maintenance gas Nitrogen as a maintenance gas is extremely suitable, the first is its high cohesion energy, as long as the high temperature and high pressure (> 500°C, >100bar) los yog nce lub zog ntawm rooj plaub, tshuaj lom neeg cov tshuaj tiv thaiv yuav tshwm sim, tam sim no tau tuav ib qho kev xav tau nitrogen ntau lawm.
