Te Miharo Hangarau o te paipa korehau

Paipa whakamahana korehau(VIP), e mōhiotia ana ko te paipa korehau (VJP), e whakamahi ana i tētahi porowhita korehau teitei (10⁻⁶ Torr) i waenganui i ngā paparanga maitai korehau porowhita hei whakatutuki i te whakawhiti wera tata-kore. I roto i ngā hanganga LNG, ka whakaitihia e ēnei pūnaha ngā reiti kohua o ia rā ki raro iho i te 0.08%, ki te whakaritea ki te 0.15% mō ngā paipa pahuka-whakamaroke tikanga. Hei tauira, ko te kaupapa LNG Gorgon a Chevron i Ahitereiria e whakamahi ana i te 18 km o te paipa korehau hei pupuri i te pāmahana -162°C puta noa i tana taunga kaweake takutai, ka tapahia ngā mate pūngao ā-tau mā te $6.2 miriona.

Ngā Wero o te Ātiki: Ngā VIP i ngā Taiao Tino Kaha

I te Tai Rāwhiti o Yamal i Siberia, ka heke te pāmahana o te takurua ki te -50°C,VIPMā ngā whatunga me te MLI 40-apa (whakamātautau paparanga maha) ka noho tonu te LNG i roto i te āhua wai i roto i ngā tukunga 2,000 km. E whakaatu ana te pūrongo a Rosneft i te tau 2023 i whakaitihia e ngā paipa cryogenic whakamatao-korehau te ngaronga o te mimiti mā te 53%, ka penapenahia te 120,000 tana o te LNG ia tau—he rite ki te whakakaha i te 450,000 kāinga Pākehā.

Ngā Auahatanga o te Ao: Ka Tūtaki te Ngāwari ki te Oranga Tonutanga

Ka honoa ngā hoahoa ranu houngā ngongo whakamahana korehaumō te hononga modular. Nō nā tata nei i whakamātauria e te whare Prelude FLNG a Shell te whariki kowakawakangā ngongo ngāwari korehau, e eke ana ki te 22% te tere ake o te uta me te tu atu ki te pēhanga 15 MPa. Hei tāpiri, ko ngā tauira MLI whakarei ake i te graphene e whakaatu ana i te kaha ki te whakaiti i te kawe wera mā te 30%, e hangai ana ki ngā whāinga whakaiti tukunga methane a te EU i te tau 2030.
