Qhov Kev Ua Yeeb Yam Zoo Kawg Nkaus ntawm cov yeeb nkab nqus tsev

Cov yeeb nkab nqus tsev(VIP), tseem hu ua cov yeeb nkab nqus tsev (VJP), siv lub annulus siab-nqus tsev (10⁻⁶ Torr) ntawm cov txheej stainless-steel concentric kom ua tiav qhov hloov pauv cua sov ze li xoom. Hauv cov khoom siv LNG, cov kab ke no txo ​​cov nqi boil-off txhua hnub kom qis dua 0.08%, piv rau 0.15% rau cov yeeb nkab ua npuas ncauj-insulated. Piv txwv li, Chevron's Gorgon LNG project hauv Australia siv 18 km ntawm cov yeeb nkab nqus tsev kom tswj tau -162 ° C kub thoob plaws nws qhov chaw xa tawm ntug dej hiav txwv, txiav cov kev poob hluav taws xob txhua xyoo los ntawm $ 6.2 lab.

Arctic Cov Kev Sib Tw: Cov VIPs hauv Cov Chaw Ib Puag Ncig Hnyav

Nyob rau hauv Siberia lub Yamal Peninsula, qhov twg lub caij ntuj no kub poob qis mus rau -50 ° C.VIPcov tes hauj lwm nrog 40-txheej MLI (ntau txheej rwb thaiv tsev) ua kom LNG tseem nyob hauv daim ntawv kua thaum lub sijhawm 2,000 km kev thauj mus los. Rosneft daim ntawv qhia xyoo 2023 qhia tias cov kav dej cryogenic uas muaj cov khoom siv nqus tsev tau txo qhov kev poob ntawm kev ua pa los ntawm 53%, txuag tau 120,000 tons ntawm LNG txhua xyoo - sib npaug rau kev siv hluav taws xob rau 450,000 lub tsev nyob hauv Tebchaws Europe.

Kev Tsim Kho Tshiab Yav Tom Ntej: Kev Yooj Yim Sib Tw Nrog Kev Ruaj Ntseg

Cov qauv tsim tshiab sib xyaw ua kecov yeeb nkab uas muaj cua sov thiab rwb thaiv tsevrau kev sib txuas modular. Shell's Prelude FLNG chaw nyuam qhuav sim corrugatedcov hoses uas yooj ywm thiab muaj lub tsho nqus tsev vacuum, ua tiav 22% ceev dua thaum tiv taus 15 MPa siab. Tsis tas li ntawd, graphene-enhanced MLI prototypes qhia tau tias muaj peev xwm txo qhov thermal conductivity los ntawm 30%, sib haum nrog EU lub hom phiaj txo qis methane emission 2030.
