Raws li qhov ua tau zoo, muaj txiaj ntsig, thiab yooj yim huv lub zog thiab cov khoom siv tshuaj lom neeg, cov roj ntsha ntuj muaj peev xwm siv tau loj. Ntawm lawv, liquefied natural gas (LNG), uas muaj qib siab ntawm kev ua lag luam, kuj tau pib nyiam cov khoom siv ntxiv rau cov khoom siv roj.
Vim tias cov kav dej LNG yog cov kav dej thauj mus los nruab nrab uas kub qis, LNG thauj los ntawm cov kav dej feem ntau nyob rau hauv lub xeev kua kub qis. Thaum cua sov sab nraud nkag mus, nws yuav yooj yim ua pa, ua rau cov kua dej ib theem hloov mus rau hauv cov roj-kua dej ob theem, lossis txawm tias lub qhov rooj roj, ua rau muaj kev nce siab thiab txo qis ntawm cov dej ntws hauv cov kav dej hauv zos, cuam tshuam loj heev rau kev thauj mus los ib txwm ntawm LNG. Yog li ntawd, kev ua pa ntawm LNG yuav tsum tau tswj hwm nruj me ntsis. Txawm li cas los xij, kev rwb thaiv tsev ntawm cov kav dej LNG tuaj yeem tiv thaiv kev nkag mus ntawm cua sov sab nraud thiab kev ua pa ntawm LNG, thiab nws qhov ua tau zoo feem ntau nyob ntawm qhov zoo ntawm kev rwb thaiv tsev ntawm cov kav dej LNG. Yog li ntawd, cov kav dej LNG yuav tsum tau txais cov kev ntsuas rwb thaiv tsev thermal , thiab lawv qhov zoo yuav tsis tsuas yog cuam tshuam rau kev thauj mus los ntawm LNG, tab sis kuj muaj qhov cuam tshuam tseem ceeb rau kev ua haujlwm ib txwm ntawm tag nrho lub cev.
LNG pipeline rwb thaiv tsev hom
Lub tshuab nqus tsev rwb thaiv tsev: Lub hauv paus ntsiab lus yog ua kom cov txheej txheem rwb thaiv tsev rau hauv qhov sib txuas sib txuas, thiab qhov chaw sab hauv raug tshem tawm mus rau qee qhov ntawm lub tshuab nqus tsev kom txo tau cov cua sov. Nyob rau hauv lub domestic LNG system, nws muaj lub sij hawm ntev siv, pom tseeb thermal rwb thaiv tsev nyhuv thiab me me zog poob. Txawm li cas los xij, vim tus nqi siab thiab lub sijhawm tsim khoom ntev, nws feem ntau yog siv rau hauv cov haujlwm tseem ceeb thiab tsis tuaj yeem siv rau ntawm qhov loj.
Stacking rwb thaiv tsev: Stacking rwb thaiv tsev yog ib txwm siv ntawm rwb thaiv tsev, uas yog, cov ntaub ntawv rwb thaiv tsev ntxeem tau raug ntsia sab nraum cov yeeb nkab, thiab cov rwb thaiv tsev tau tiav vim hais tias cov hlwb tau ntim nrog cov huab cua ib txwm muaj (los yog lwm yam gases). Cov nyhuv thermal rwb thaiv tsev yog me ntsis qis dua li ntawm lub tshuab nqus tsev rwb thaiv tsev, tab sis nws muaj cov qauv yooj yim, tus nqi qis, thiab kev ua haujlwm yooj yim thiab txij nkawm. Tam sim no, cov kav dej LNG hauv tsev feem ntau siv cov qauv no rau kev rwb thaiv tsev hauv cov kav dej.
Hauv kev ua lag luam tam sim no, cov ntaub ntawv rwb thaiv tsev uas twb muaj lawm feem ntau siv cov ntaub ntawv polyurethane thiab ua npuas ncauj ua npuas ncauj raws li qhov sib txawv LNG kub. Piv nrog cov khoom siv thermal rwb thaiv tsev xws li polyurethane thiab ua npuas ncauj iav, melamine ua npuas ncauj muaj qhov zoo dua. Melamine ua npuas ncauj muaj ntau yam kev tiv thaiv huab cua (txo 196 degrees Celsius mus rau 200 degrees Celsius), tuav lub cev ruaj khov thiab cov qauv tshuaj nyob rau hauv qhov kub thiab txias, thiab muab cov thermal conductivity zoo heev (thermal conductivity coefficient, 0.032 W / (m * K)) thiab lub suab nqus kev ua tau zoo (0.95NRC), lub teeb yuag, kev tiv thaiv ib puag ncig thiab kev nyab xeeb ntawm cov yeeb nkab.
Hauv kev tsim engineering ntawm LNG cov chaw cog qoob loo, qhov xwm txheej tiag tiag ntawm qhov project yuav tsum tau txheeb xyuas tshwj xeeb, thiab cov khoom siv thermal rwb thaiv tsev tsim nyog thiab cov khoom siv rwb thaiv tsev txias yuav tsum tau xaiv thiab siv. Nws cov ntsiab lus tseem ceeb suav nrog:
- Qhov tsawg kawg nkaus kev nyab xeeb siv kub ntawm cov khoom siv rwb thaiv tsev txias yuav tsum qis dua qhov kub ntawm qhov nruab nrab thaum lub sijhawm ua haujlwm;
- Kev tiv thaiv hluav taws kev ua haujlwm ntawm cov ntaub ntawv rwb thaiv tsev txias yuav tsum ua tau raws li cov qauv hauv lub tebchaws tam sim no;
- Ua ntej siv cov khoom siv rwb thaiv tsev txias nrog cov dej vapor permeability zoo heev los xyuas kom meej lub sijhawm ntev ntawm cov khoom ua haujlwm;
- Cov khoom siv rwb thaiv tsev txias yuav tsum muaj qhov zoo ntawm qhov chaw txiav lossis txiav kev ua haujlwm, kev tsim kho yooj yim, thiab yooj yim rau ntawm qhov chaw teeb tsa;
- Muab qhov tseem ceeb rau cov khoom siv lossis cov khoom lag luam nrog cov txiaj ntsig kev lag luam siab;
- Txo cov nqi ntawm kev ua haujlwm txhua hnub tom qab lub tshuab cua txias tau muab tso rau hauv kev tsim khoom thiab txhim kho cov khoom siv rov qab.
Raws li cov kev cai saum toj no, melamine ua npuas ncauj tuaj yeem siv ua cov khoom siv rwb thaiv tsev thiab cov khoom siv khaws cia txias rau LNG cov kav dej, thiab melamine ua npuas ncauj ua lub luag haujlwm tseem ceeb hauv kev rwb thaiv tsev thiab kev khaws cia txias ntawm LNG cov kav dej. Melamine ua npuas ncauj yog cov khoom siv yas elastomer uas muaj cov qauv network peb-seem. Nws tseem tswj tau cov qauv lub cev thiab tshuaj lom neeg tiav ntawm -196 degrees Celsius, yog li nws tseem muaj cov thermal conductivity zoo heev ntawm qhov kub qis thiab tiv thaiv kev sib hloov ntawm sab hauv thiab sab nraud. Kev ua kom sov thiab hluav taws xob zoo heev, tiv taus hluav taws kub zoo heev (B1, UL94 V0 thiab HL-1) thiab cov khoom rwb thaiv tsev (tsis tsim cov khoom zoo li qub thiab tiv thaiv hluav taws xob), tiv taus kua qaub thiab alkali, tiv taus corrosion, tiv taus kev laus, lub teeb yuag thiab qhov kub qis, thiab lwm yam kev ua tau zoo, thiab vim tias melamine resin ua npuas ncauj yog cov khoom siv elastic tab sis tsis yog fiber, tsis muaj hmoov av, tsis muaj halogenated thiab hydrocarbons, tsis muaj nplaim taws thiab / lossis cov hlau hnyav lom, tshwj xeeb tshaj yog haum rau cov chaw uas muaj kev xav tau zoo rau ib puag ncig, txias cia (chaw ua tshuaj, chaw ua txiv hmab txiv ntoo thiab zaub khaws cia, chaw ua zaub mov, chaw ua nqaij thiab chaw ua dej haus txias) rwb thaiv tsev txias ( rwb thaiv tsev thermal thiab acoustic), tub yees / lub tub yees txias rwb thaiv tsev ( rwb thaiv tsev thermal thiab acoustic), LNG liquefied cia tank txias rwb thaiv tsev ( rwb thaiv tsev thermal thiab acoustic), LNG liquefied thauj tsheb lossis Nkoj txias thiab thermal rwb thaiv tsev ( rwb thaiv tsev thermal thiab acoustic).
