I-Engineering Marvel yepayipi elinejakhethi ye-vacuum

Vacuum insulated ipayipi(I-VIP), eyaziwa nangokuthi ipayipi le-vacuum jacketed (VJP), isebenzisa i-vacuum annulus ephezulu (10⁻⁶ Torr) phakathi kwezendlalelo zensimbi engagqwali egxilile ukuze kuzuzwe ukudluliswa kokushisa okucishe kungabi ziro. Kungqalasizinda ye-LNG, lezi zinhlelo zehlisa izinga lokubilisa nsuku zonke libe ngaphansi kuka-0.08%, uma kuqhathaniswa no-0.15% wamapayipi avamile afakwe igwebu. Isibonelo, iphrojekthi ye-Chevron's Gorgon LNG e-Australia isebenzisa ipayipi elinejakhethi engu-18 km ukugcina izinga lokushisa elingu- -162°C endaweni yonkana yokuthekelisa ogwini, inciphisa ukulahlekelwa kwamandla onyaka ngezigidi ezingu-6.2 zamaRandi.

Izinselele ze-Arctic: Ama-VIP Ezindaweni Eziphakeme Kakhulu

ENhlonhlweni yaseYamal yaseSiberia, lapho amazinga okushisa ebusika ehla aze afike ku-50°C.I-VIPamanethiwekhi ane-MLI enezingqimba ezingu-40 (ukufakwa kwezingqimba eziningi) aqinisekisa ukuthi i-LNG ihlala isesimweni esiwuketshezi ngesikhathi sokuthunyelwa okungu-2,000 km. Umbiko we-Rosneft wango-2023 ugqamisa ukuthi amapayipi e-vacuum-insulated cryogenic anciphisa ukulahlekelwa kokuhwamuka ngamaphesenti angama-53, konga amathani ayi-120,000 e-LNG ngonyaka—okulingana nokunika amandla amakhaya angama-450,000 aseYurophu.

Okusungulwe Kwesikhathi esizayo: Ukuvumelana nezimo kuhlangabezana nokusimama

Imiklamo ye-hybrid ekhulayo ihlanganisai-vacuum-insulated hosesngokuxhumeka kwe-modular. Isikhungo sakwaShell's Prelude FLNG sisanda kuhlolwa sinothayelaamapayipi e-vacuum-jacket aguquguqukayo, ifinyelela isivinini sokulayisha esisheshayo esingu-22% ngenkathi imelana nokucindezela okungu-15 MPa. Ukwengeza, ama-prototypes e-MLI athuthukisiwe e-graphene akhombisa amandla okuqhubeka nokusika ukuqhutshwa kwe-thermal ngama-30%, kuhambisana nezinhloso zokunciphisa ukukhishwa kwe-methane ye-EU ka-2030.
