Chishamiso cheUinjiniya chepombi ine jekete ye vacuum

Pombi yekudzivirira mvura inodziya(VIP), inozivikanwawo sepombi ye vacuum jacketed (VJP), inoshandisa pombi ye vacuum annulus ine simba (10⁻⁶ Torr) pakati pezvikamu zvesimbi isina ngura kuti iite kuti kupisa kupfuure ne zero. Muzvivakwa zve LNG, masisitimu aya anoderedza mwero wekupisa kwezuva nezuva kusvika pasi pe 0.08%, zvichienzaniswa ne 0.15% yepombi dzemazuva ano dzakaputirwa nefoam. Semuenzaniso, chirongwa cheChevron cheGorgon LNG muAustralia chinoshandisa pombi ye vacuum jacketed ine makiromita gumi nemasere kuchengetedza tembiricha ye -162°C munzvimbo yayo yekutengesera kunze kwenyika, zvichideredza kurasikirwa kwesimba pagore nemadhora mamiriyoni matanhatu nemazana maviri emadhora.

MuYamal Peninsula yeSiberia, uko tembiricha yechando inodzikira kusvika -50°C,VIPnetwork dzine 40-layer MLI (multilayer insulation) dzinoita kuti LNG irambe iri muchimiro chemvura panguva yekutumira zvinhu mu2,000 km. Mushumo waRosneft wegore ra2023 unoratidza kuti mapombi emvura anoputirwa ne vacuum-insulated cryogenic akaderedza kurasikirwa kwevaporizer ne53%, zvichichengetedza matani 120,000 eLNG pagore—zvakaenzana nekupa simba kudzimba 450,000 dzekuEurope.

Magadzirirwo emhando yepamusoro ehybrid anobatanidzwamapombi anoputirwa ne vacuumyekubatanidza modular. Nzvimbo yeShell's Prelude FLNG yakaedzwa munguva pfupi yapfuuramapombi anochinjika ebhachi re vacuum, ichikwanisa kukurumidza kurodha ne22% uku ichitsungirira kumanikidzwa kwe15 MPa. Pamusoro pezvo, ma prototypes eMLI akagadziridzwa negraphene anoratidza mukana wekuderedza zvakanyanya kufambiswa kwemhepo ne30%, zvichienderana nezvinangwa zveEU zvekuderedza methane emission muna 2030.
