ʻO ka ʻenekinia kupanaha o ka paipu ʻaʻahu ʻaʻahu

ʻO ka paipu hoʻoheheʻe ʻia(VIP), ʻike ʻia hoʻi ʻo ka paipu ʻaʻahu ʻaʻahu (VJP), hoʻohana i kahi annulus hau-māmā kiʻekiʻe (10⁻⁶ Torr) ma waena o nā papa kila stainless concentric e hoʻokō i ka hoʻoili wela kokoke-zero. I loko o nā ʻōnaehana LNG, hoʻemi kēia mau ʻōnaehana i ka nui o ka paila i kēlā me kēia lā ma lalo o 0.08%, i hoʻohālikelike ʻia me 0.15% no nā paipu hoʻoheheʻe ʻia maʻamau. No ka laʻana, hoʻohana ʻo Chevron's Gorgon LNG ma Australia i 18 km o ka paipu ʻaʻahu ʻaʻahu no ka mālama ʻana i nā mahana -162°C ma waena o kona kahua hoʻokuʻu kahakai, e ʻoki ana i nā lilo o ka ikehu makahiki e $6.2 miliona.

Nā Luʻi Arctic: Nā VIP i nā Kaiapuni Kūʻē

Ma ka moku ʻo Yamal Peninsula o Siberia, kahi e hāʻule ai ka mahana hoʻoilo a hiki i -50°C.VIPnā pūnaewele me 40-layer MLI (multilayer insulation) e hōʻoia i ka noho ʻana o ka LNG i loko o ke ʻano wai i ka 2,000 km trans-shipments. Hōʻike ka hōʻike a Rosneft i ka makahiki 2023 i ka hoʻemi ʻana o ka paipu cryogenic vacuum-insulated i ka nalowale o ka vaporization e 53%, e mālama ana i 120,000 tons LNG i kēlā me kēia makahiki-e like me ka mana o 450,000 mau hale ʻEulopa.

Nā mea hou i ka wā e hiki mai ana: Hiki ke hoʻokō i ka hoʻomau

Hoʻohui ʻia nā hoʻolālā hybrid e puka mai ananā hoses i hoʻopaʻa ʻiano ka hoʻohui modular. Ua ho'āʻo hou ʻia ka hale hana Prelude FLNG o Shell i corrugatedʻūpaʻa ʻaʻahu-ʻaʻahu ʻoluʻolu, e loaʻa ana i ka 22% ʻoi aku ka wikiwiki o ka hoʻouka ʻana me ka pale ʻana i ke kaomi 15 MPa. Hoʻohui ʻia, hōʻike nā prototypes MLI i hoʻonui ʻia i ka graphene i hiki ke hoʻoemi hou i ka conductivity thermal e 30%, e hoʻohālikelike ana me nā pahuhopu hoʻemi methane emission o EU i ka makahiki 2030.
