Cryogenic kua xws li kua nitrogen (LN2), kua hydrogen (LH2), thiab liquefied natural gas (LNG) yog qhov tseem ceeb hauv ntau yam lag luam, los ntawm kev siv kho mob mus rau kev tsim hluav taws xob. Kev thauj mus los ntawm cov khoom kub qis no yuav tsum muaj cov tshuab tshwj xeeb los tswj lawv qhov txias txias thiab tiv thaiv evaporation. Ib qho ntawm cov thev naus laus zis zoo tshaj plaws rau kev thauj cov kua cryogenic yog cov nqus tsev insulated pipeline. Hauv qab no, peb yuav tshawb xyuas seb cov tshuab no ua haujlwm li cas thiab vim li cas lawv tseem ceeb heev rau kev thauj cov kua dej cryogenic kom nyab xeeb.

Qhov Kev Sib Tw ntawm Kev Thauj Khoom Cryogenic Liquids

Cryogenic kua yog khaws cia thiab thauj ntawm qhov kub ntawm -150 ° C (-238 ° F). Nyob rau qhov kub tsis tshua muaj, lawv zoo li evaporate sai yog tias raug rau ambient tej yam kev mob. Qhov kev sib tw tseem ceeb yog txo qis kev hloov pauv cua sov kom cov khoom no nyob rau hauv lawv cov kua hauv lub xeev thaum thauj. Ib qho kev nce hauv qhov kub tuaj yeem ua rau vaporization sai, ua rau cov khoom poob thiab muaj peev xwm muaj kev nyab xeeb.

Vacuum Insulated Pipeline: Tus yuam sij rau kev thauj mus los zoo

Nqus insulated pipelines(VIPs) yog ib qho kev daws teeb meem tseem ceeb rau kev thauj cov kua dej cryogenic hla qhov ntev thaum txo qis kev hloov pauv cua sov. Cov kav dej no muaj ob txheej: cov yeeb nkab sab hauv, uas nqa cov kua dej cryogenic, thiab cov yeeb nkab sab nraud uas kaw cov yeeb nkab sab hauv. Nyob nruab nrab ntawm ob txheej no yog lub tshuab nqus tsev, uas ua haujlwm ua ib qho thaiv thaiv kom tsis txhob muaj cua sov thiab hluav taws xob. Covnqus tsev insulated pipelinethev naus laus zis txo qis thermal poob, kom ntseeg tau tias cov kua tseem nyob ntawm qhov xav tau kub thoob plaws nws txoj kev taug.

Daim ntawv thov hauv LNG Tsheb thauj mus los

Liquefied natural gas (LNG) yog cov roj uas nrov thiab yuav tsum tau thauj ntawm qhov kub thiab txias li -162 ° C (-260 ° F).Nqus insulated pipelinesyog siv dav hauv LNG cov chaw thiab cov chaw nres tsheb kom txav LNG los ntawm cov tso tsheb hlau luam mus rau nkoj lossis lwm lub thawv thauj khoom. Kev siv VIPs ua kom muaj cua sov tsawg tsawg, txo cov roj boil-off (BOG) tsim thiab tswj LNG hauv nws lub xeev liquefied thaum lub sij hawm thauj khoom thiab tshem tawm cov haujlwm.

Liquid Hydrogen thiab Liquid Nitrogen Transportation

Ib yam li ntawd,lub tshuab nqus tsev insulated pipelinesyog qhov tseem ceeb hauv kev thauj mus los ntawm cov kua hydrogen (LH2) thiab kua nitrogen (LN2). Piv txwv li, kua hydrogen feem ntau yog siv nyob rau hauv qhov chaw tshawb nrhiav thiab roj cell technology. Nws qhov kub tsis tshua muaj kub ntawm -253 ° C (-423 ° F) yuav tsum muaj kev thauj mus los tshwj xeeb. VIPs muab cov kev daws teeb meem zoo tshaj plaws, tso cai rau kev nyab xeeb thiab ua haujlwm tau zoo ntawm LH2 yam tsis muaj kev poob loj vim kev hloov hluav taws xob. Cov kua nitrogen, dav siv hauv kev kho mob thiab kev lag luam kev siv, kuj tau txais txiaj ntsig los ntawm VIPs, ua kom nws qhov kub thiab txias thoob plaws hauv cov txheej txheem.

Xaus: Lub Luag Haujlwm ntawmNqus Insulated Pipelines Nyob rau yav tom ntej ntawm Cryogenics

Raws li kev lag luam txuas ntxiv cia siab rau cov kua cryogenic, lub tshuab nqus tsev insulated pipelinesyuav ua lub luag haujlwm tseem ceeb hauv kev ua kom lawv txoj kev nyab xeeb thiab kev thauj mus los tau zoo. Nrog lawv lub peev xwm los txo cov cua sov, tiv thaiv cov khoom poob, thiab txhim kho kev nyab xeeb, VIPs yog ib qho tseem ceeb hauv kev loj hlob cryogenic sector. Los ntawm LNG mus rau cov kua hydrogen, cov thev naus laus zis no ua kom ntseeg tau tias cov kua dej uas muaj qhov kub thiab txias tuaj yeem thauj tau nrog kev cuam tshuam ib puag ncig tsawg thiab ua haujlwm siab tshaj plaws.
