Iyo Injiniya Marvel yevacuum jaketi pombi

Vacuum insulated pombi(VIP), inonziwo vacuum jacketed pombi (VJP), inoshandisa yakakwira-vacuum annulus (10⁻⁶ Torr) pakati pematanho esimbi isina simbi kuti isvike pedyo-zero kupisa kwekufambisa. Muzvivakwa zveLNG, masisitimu aya anoderedza huwandu hwemazuva ese hwekubikira kusvika pazasi 0.08%, zvichienzaniswa ne0.15% yemapombi akajairwa nefuro. Semuyenzaniso, chirongwa cheChevron's Gorgon LNG muAustralia chinoshandisa 18 km yepombi yevacuum jekete kuchengetedza -162°C tembiricha pachiteshi chengarava chekutengesa kunze kwenyika, ichicheka kurasikirwa kwegore negore nemadhora mazana matanhatu nemazana maviri emadhora.

Matambudziko eArctic: VIPs munzvimbo Dzakanyanya

MuYamal Peninsula yeSiberia, uko tembiricha yechando inodzika kusvika -50°C.VIPnetwork ine 40-layer MLI (multilayer insulation) inoita kuti LNG irambe iri muchimiro chemvura panguva ye2,000 km trans-shipment. Rosneft's 2023 mushumo unosimbisa kuti vacuum-insulated cryogenic piping yakaderedza kurasikirwa kwemhepo ne53%, kuchengetedza zviuru zana nemakumi maviri ezviuru zvematani eLNG pagore - zvakaenzana nekusimbisa dzimba mazana mana nemakumi mashanu ezviuru zveEurope.

Future Innovations: Flexibility Inosangana Nekusimba

Emerging hybrid dhizaini inobatanidzavacuum-insulated hoseskune modular yekubatanidza. Shell's Prelude FLNG nzvimbo nguva pfupi yadarika yakaedzwa mararavacuum-jacket flexible hoses, kuwana 22% nekukurumidza kurodha kumhanya uchishingirira 15 MPa kudzvanywa. Pamusoro pezvo, magraphene-akakwidziridzwa MLI prototypes anoratidza kugona kuenderera mberi kutema conductivity yemafuta ne30%, ichienderana neEU's 2030 methane emission emission targets.
