Cryogenic kua xws li kua nitrogen (LN2), kua hydrogen (LH2), thiab liquefied nkev (lng) yog qhov tseem ceeb hauv kev lag luam kho mob rau kev tsim kho hluav taws xob. Kev thauj mus los ntawm cov tshuaj uas tsawg-kub yuav tsum muaj cov qauv tshwj xeeb kom tswj tau lawv qhov txias txias thiab tsis yooj yim. Ib qho ntawm cov thev naus laus zis zoo tshaj plaws rau kev thauj cov kua cryogenic kua yog tus Lub Tshuab Nqus Tsev Insulated PipelineCov. Hauv qab no, peb yuav tshawb nrhiav seb cov kab ke no ua haujlwm thiab vim li cas lawv thiaj yog qhov kev nyab xeeb thauj cov kua cinogenic.

Qhov kev sib tw ntawm thauj cov kua tshuab cryogenic

Cryogenic kua tau khaws cia thiab thauj ntawm qhov kub thiab txias hauv qab -150 ° C (-238 ° F). Ntawm qhov chaw kub me, lawv zoo li yaj sai tshaj yog raug rau cov mob uas muaj kev mob siab. Qhov kev sib tw tseem ceeb yog txo cov cua sov hloov kom cov tshuaj no hauv lawv lub xeev ua kua thaum thauj. Txhua qhov nce hauv qhov ntsuas kub tuaj yeem ua rau muaj vaporization sai, ua rau cov khoom poob thiab muaj peev xwm kev nyab xeeb kev nyab xeeb.

Lub tshuab nqus tsev insulated raj dej: tus yuam sij rau kev thauj mus los ua tau zoo

Lub tshuab nqus tsev insulated pipelines(VIPs) yog ib qho kev daws qhov tseem ceeb rau kev thauj cov kua cryogenic ntau dhau thaum mus deb thaum muaj kev kub ntxhov. Cov kab hluav taws xob no muaj ob txheej: cov yeeb nkab sab hauv, uas nqa cov kua cryogenic, thiab cov yeeb nkab sab nraud uas tau muab cov yeeb nkab sab hauv. Nruab nrab ntawm ob txheej yog lub tshuab nqus tsev, uas ua haujlwm ua cov thaiv kev insulating los txo cov cua sov thiab hluav taws xob. TusLub Tshuab Nqus Tsev Insulated PipelineCov thev naus laus zis ntau txo cov thermal poob, kom cov kua seem ntawm qhov yuav tsum tau kub thoob plaws nws txoj kev taug.

Daim Ntawv Thov Hauv LNG Tsheb Thauj Mus Los

Liquefied nkev (LNG) yog cov roj nrov siv thiab yuav tsum tau thauj ntawm qhov kub uas muaj -162 ° F).Lub tshuab nqus tsev insulated pipelinestau siv dav hauv Lng chaw thiab cov terminals mus txav lng los ntawm kev tso tsheb hlau luam rau nkoj lossis lwm lub thawv thauj khoom. Kev siv vips ua kom muaj cua sov tsawg tsawg, txo cov roj boil

Kua hydrogen thiab ua kua nitrogen thauj mus los

Zoo sib xws,Lub tshuab nqus tsev insulated pipelinesYog qhov tseem ceeb hauv kev thauj mus los ntawm cov kua hydrogen (LH2) thiab ua kua nitrogen (ln2). Piv txwv li, kua hydrogen feem ntau yog siv hauv kev tshawb nrhiav kev tshawb fawb thiab roj ntawm cov thev naus laus zis. Nws tsawg kawg boiling taw tes ntawm -253 ° C (-423 ° F) yuav tsum muaj kev thauj mus los tshwj xeeb. VIPS muab txoj kev daws teeb meem zoo tagnrho, tso cai rau kev nyab xeeb thiab kev ua tau zoo ntawm LH2 yam tsis muaj qhov tseem ceeb poob vim kub. Ua kua nitrogen, siv tau dav hauv kev kho mob thiab kev siv khoom siv, kuj tseem muaj txiaj ntsig los ntawm vips, kom peb lub zog kub ruaj khov thoob plaws hauv cov txheej txheem.

Xaus: Lub Luag HaujlwmLub tshuab nqus tsev insulated pipelines yav tom ntej ntawm cryogenics

Raws li kev lag luam txuas ntxiv mus cia siab rau cov kua roj cryogenic, Lub tshuab nqus tsev insulated pipelinesYuav ua lub luag haujlwm tseem ceeb zuj zus hauv kev ua kom lawv muaj kev nyab xeeb thiab txuag tau. Nrog lawv lub peev xwm los txo cov cua sov hloov, tiv thaiv cov khoom poob, thiab txhim kho kev nyab xeeb, vips yog ib qho tseem ceeb hauv kev loj hlob cryogenic dortor. Los ntawm LNG mus ua kua rau ua kua dej, cov thev naus laus zis uas muaj dej tsawg tuaj yeem thauj nrog kev cuam tshuam ib puag ncig thiab kev ua tau zoo tshaj plaws.
