The Engineering Marvel wa vacuum jekete chitoliro

Vacuum insulated chitoliro(VIP), yomwe imadziwikanso kuti vacuum jacketed pipe (VJP), imagwiritsa ntchito vacuum annulus (10⁻⁶ Torr) pakati pa zigawo zazitsulo zosapanga dzimbiri kuti ikwaniritse kutentha kwapafupi ndi ziro. M'magawo a LNG, machitidwewa amachepetsa chithupsa chatsiku ndi tsiku mpaka pansi pa 0.08%, poyerekeza ndi 0.15% ya mapaipi opangidwa ndi thovu. Mwachitsanzo, pulojekiti ya Chevron's Gorgon LNG ku Australia imagwiritsa ntchito chitoliro cha 18 km cha vacuum jacket kuti isunge kutentha kwa -162 ° C kudutsa gombe lake lotumiza kunja, ndikuchepetsa kuwonongeka kwa mphamvu pachaka ndi $ 6.2 miliyoni.

Zovuta za Arctic: VIPs Kumalo Opambana

Ku Yamal Peninsula ku Siberia, komwe kutentha kumatsika mpaka -50 ° C.VIPmaukonde okhala ndi 40-layer MLI (multilayer insulation) amawonetsetsa kuti LNG imakhalabe yamadzimadzi panthawi yotumiza 2,000 km. Lipoti la Rosneft la 2023 likuwonetsa kuti mapaipi a vacuum-insulated cryogenic amachepetsa kutayika kwa nthunzi ndi 53%, ndikupulumutsa matani 120,000 a LNG pachaka-zofanana ndi kupatsa mphamvu nyumba 450,000 zaku Europe.

Zam'tsogolo: Kusinthasintha Kukumana ndi Kukhazikika

Ma hybrids omwe akutuluka amaphatikizanavacuum-insulated mabombakwa kulumikizana kwa modular. Malo a Shell's Prelude FLNG adayesedwa posachedwapavacuum-jacket flexible hoses, kukwaniritsa kuthamanga kwa 22% mofulumira pamene mukulimbana ndi 15 MPa. Kuphatikiza apo, zojambula za MLI zokongoletsedwa ndi graphene zikuwonetsa kuthekera kochepetsera mphamvu yamafuta ndi 30%, mogwirizana ndi zolinga za EU zochepetsera mpweya wa methane mu 2030.
