Igitangaza cy'Ubwubatsi bw'imiyoboro ifite ikoti ry'umwuka

Umuyoboro ushyushya ukoresheje icyuma gikonjesha(VIP), izwi kandi nka vacuum jacketed pipe (VJP), ikoresha vacuum annulus nyinshi (10⁻⁶ Torr) hagati y’ibice by’icyuma kitagira umugese kugira ngo igere kuri zero mu gutwara ubushyuhe. Mu bikorwa remezo bya LNG, izi sisitemu zigabanya igipimo cya buri munsi cyo gutemba kikagera munsi ya 0.08%, ugereranije na 0.15% ku miyoboro isanzwe ifuro. Urugero, umushinga wa Chevron wa Gorgon LNG muri Ositaraliya ukoresha imiyoboro idafite umugese ifite uburebure bwa kilometero 18 kugira ngo igumane ubushyuhe bwa -162°C ku nkengero z’aho ibicuruzwa bijyanwa mu mahanga, bigabanyije igihombo cy’ingufu cya miliyoni 6.2 z’amadolari buri mwaka.

Ibibazo byo mu gace ka Arctique: Abantu bakomeye mu bidukikije bikomeye

Mu gace ka Yamal muri Siberiya, aho ubushyuhe bw'itumba bugabanuka bukagera kuri -50°C,VIPImiyoboro ifite MLI y’ibice 40 (multilayer insulation) ituma LNG iguma mu buryo bw’amazi mu gihe cyo kohereza mu kirere mu birometero 2,000. Raporo ya Rosneft yo mu 2023 igaragaza ko imiyoboro ya cryogenic ikoresha vacuum-insulated yagabanyije igihombo cyo gushonga ku kigero cya 53%, bigatuma toni 120.000 za LNG zigabanuka buri mwaka—bingana no gukoresha ingufu mu ngo 450.000 z’i Burayi.

Udushya mu gihe kizaza: Guhuza n'imimerere bihura n'iterambere rirambye

Imiterere mishya y'ibinyabutabire irahuzwaimiyoboro ikoreshwa mu gufunga imashinikugira ngo habeho uburyo bwo guhuza modular. Ikigo cya Shell's Prelude FLNG giherutse kugeragezwaimiyoboro yoroshye yo mu ikoti ry'umwuka, kugera ku muvuduko wihuta wa 22% mu gihe bihangana n'umuvuduko wa MPa 15. Byongeye kandi, imiterere ya MLI yongerewe graphene igaragaza ko ishobora kugabanya cyane ubwiyongere bw'ubushyuhe ku kigero cya 30%, bihuye n'intego z'Umuryango w'Ubumwe bw'u Burayi zo kugabanya imyuka ya methane yo mu 2030.
