Cov ntsiab lus
Lub LNG cryogenic cia tank yog cov cuab yeej tseem ceeb rau khaws cia liquefied natural gas (LNG), nrog rau qhov kub thiab txias ntawm -192 degrees. Nws tuaj yeem muab faib ua ntsug LNG cryogenic cia tso tsheb hlau luam thiab kab rov tav LNG cryogenic cia tso tsheb hlau luam.
Raws li cov khoom siv tseem ceeb hauv cov roj liquefied natural gas (LNG) cov tshuab cia, LNG cryogenic cia tso tsheb hlau luam tshwj xeeb yog tsim los kom muaj cov purified LNG uas tau txias rau -162℃nyob rau hauv atmospheric siab (nrog rau qhov kub siab ua hauj lwm tsawg li -192 degree). Cov cuab yeej tseem ceeb ntawm LNG yog nws qhov ntim-tsuas yog 1/625 ntawm cov pa roj carbon monoxide. Txawm hais tias tus yam ntxwv no txhawb nqa LNG kev thauj mus los thiab kev khaws cia, nws tseem ua kom nruj cov kev cai ntawm cov tso tsheb hlau luam 'kub kub tsis kam, thermal rwb thaiv tsev efficiency, thiab kev nyab xeeb kev ua haujlwm. Yog li ntawd, LNG cryogenic cia tso tsheb hlau luam yog ib qho tseem ceeb hub integrating tag nrho LNG tus nqi saw, encompassing txais tos, cia, tsheb thauj mus los, thiab kev siv kawg.
Hais txog kev tsim qauv, "ob npaug- txheej tiv thaiv + siab- thermal rwb thaiv tsev" yog lub ntsiab lus ntawm LNG cryogenic cia tso tsheb hlau luam. Tus qauv kev teeb tsa txais yuav ob - txheej txheej txheej txheem uas muaj lub tank sab hauv thiab lub tank sab nraud:
1. Inner Tank: Ua lub luag haujlwm tseem ceeb hauv kev sib cuag nrog LNG, feem ntau yog tsim los ntawm 9% npib tsib xee steel- cov khoom pov thawj kom khaws tau qhov tshwj xeeb toughness txawm nyob rau ntawm ultra- kub ntawm -196℃.
2. Thermal Insulation System: Qhov sib txawv ntawm qhov sib txawv ntawm lub tank sab hauv thiab sab nrauv, nrog rau lub hauv paus ntawm lub tank, tau ntim nrog cov khoom siv hluav taws xob siab ({1}}cov ntaub ntawv thermal rwb thaiv tsev xws li nthuav dav perlite thiab foam iav blocks. Cov chav nyob qib siab ntxiv suav nrog "nqus + ntau- txheej rwb thaiv tsev" thev naus laus zis, uas, thaum ua ke nrog lub qab nthab insulated ntawm lub tank saum, txo qis cua sov thiab txo qis LNG vaporization poob mus rau qhov loj tshaj.
Raws li daim ntawv thov scenarios, LNG cryogenic cia tso tsheb hlau luam feem ntau categorized ua ob hom, txhua tus haum rau cov kev xav tau tshwj xeeb:
- Vertical Tanks: Siv lawv cov qauv ntsug, lawv muaj qhov zoo sib xws ntawm cov hneev taw me me ua ke nrog lub peev xwm loj. Qhov no ua rau lawv qhov kev xaiv zoo tshaj plaws rau cov chaw loj - xws li LNG txais cov chaw nres tsheb thiab cov chaw khaws cia hauv nruab nrab.
- Kab rov tav Tank: Featuring lub compact kab rov tav layout, lawv pab kom yooj yim installation thiab tuaj yeem ua ke rau hauv skid - mounted units. Cov no yog qhov tsim nyog rau cov ntawv thov kev lag luam suav nrog me me - chaw nres tsheb roj av, LNG tsheb refueling chaw, thiab kev lag luam- muaj cov tshuab khaws cia.
Kev nyab xeeb kev nyab xeeb yog qhov tseem ceeb tshaj plaws hauv kev ua haujlwm tank, pom tau los ntawm "kev tiv thaiv- saib xyuas- kev teb thaum muaj xwm txheej ceev":
- Kev Tswj Siab: Lub tank sab hauv qhov kev nyab xeeb valve thiab lub tank sab nrauv lub rupture disc tsim ib tug dual siab nyem mechanism. Tsis tas li ntawd, qee lub tso tsheb hlau luam tau nruab nrog BOG (Boiled Off Gas) compressors kom rov qab tau cov pa vaporized, txhim kho kev nyab xeeb thiab kev siv hluav taws xob.
- Tiag tiag- Sijhawm Saib Xyuas: Cov yam ntxwv tseem ceeb xws li qib ua kua, siab, thiab qhov kub thiab txias tau taug qab tsis tu ncua hauv lub sijhawm tiag tiag ntawm kev tswj hwm lub cev. Leak detection sensors kuj tau teeb tsa kom ceeb toom cov neeg ua haujlwm tam sim rau qhov tsis txaus ntseeg xws li lub tshuab nqus tsev tsis ua haujlwm.
Cov txheej txheem tu vaj tse yog qhov tseem ceeb rau kev ua kom ntev - ua haujlwm nyab xeeb, nrog cov kev cai tseem ceeb suav nrog:
- Kev Ntsuas Lub Tshuab Nqus Tsev Txhua Xyoo: Lub tshuab nqus tsev kawm ntawv yuav tsum tsawg dua lossis sib npaug li 1 Pa rau cov tso tsheb hlau luam sov thiab Tsawg dua lossis sib npaug li 0.5 Pa rau cov tso tsheb hlau luam txias kom ntseeg tau tias muaj kev rwb thaiv tsev zoo.
- Tsis tu ncua Calibration & Inspection: Cov cuab yeej muaj kev nyab xeeb yuav tsum tau ntsuas raws sij hawm, thiab kev sib khi ntawm lub tank qauv yuav tsum tau tshuaj xyuas tsis tu ncua kom tsis txhob muaj kev pheej hmoo.
