Lub Engineering Marvel ntawm lub tshuab nqus tsev cov yeeb nkab

Vacuum insulated yeeb nkab(VIP), tseem hu ua lub tshuab nqus tsev cov yeeb nkab (VJP), siv lub tshuab nqus tsev siab (10⁻⁶ Torr) ntawm cov txheej txheem stainless-steel kom ua tiav zero tshav kub hloov. Nyob rau hauv LNG infrastructure, cov tshuab no txo ​​qis txhua hnub boil-off tus nqi kom qis dua 0.08%, piv rau 0.15% rau cov pa ua npuas dej-insulated kav. Piv txwv li, Chevron's Gorgon LNG project hauv Australia siv 18 km ntawm lub tshuab nqus tsev cov yeeb nkab kom tswj tau -162 ° C qhov kub thiab txias thoob plaws nws cov ntug hiav txwv xa tawm, txiav txhua xyoo hluav taws xob poob los ntawm $ 6.2 lab.

Cov Kev Sib Tw Arctic: VIPs hauv Ib puag ncig hnyav

Nyob rau hauv Siberia lub Yamal Peninsula, qhov twg lub caij ntuj no kub poob mus rau -50 ° C,VIPcov tes hauj lwm nrog 40-txheej MLI (multilayer rwb thaiv tsev) kom ntseeg tau tias LNG tseem nyob hauv cov kua hauv lub sijhawm 2,000 km kev xa khoom xa tuaj. Rosneft's 2023 tsab ntawv ceeb toom qhia tias lub tshuab nqus tsev insulated cryogenic piping txo vaporization los ntawm 53%, txuag 120,000 tons ntawm LNG txhua xyoo - sib npaug rau 450,000 European tsev.

Yav Tom Ntej Innovations: Flexibility ntsib Sustainability

Kev tsim tawm hybrid sib xyaw ua kelub tshuab nqus tsev insulated hosesrau modular connectivity. Shell's Prelude FLNG qhov chaw tsis ntev los no tau sim corrugatedVacuum-jacket saj zawg zog hoses, ua tiav 22% ceev loading ceev thaum withstanding 15 MPa siab. Tsis tas li ntawd, graphene-enhanced MLI prototypes qhia tau tias muaj peev xwm ua kom cov thermal conductivity ntxiv los ntawm 30%, ua raws li EU lub hom phiaj 2030 methane emission txo.
