Ubunjineli obumangalisayo bombhobho ofunxayo onebhatyi

Vacuum insulated umbhobho(VIP), ekwaziwa ngokuba ngumbhobho ovacuum jacketed (VJP), isebenzisa i-vacuum annulus ephezulu (10⁻⁶ Torr) phakathi kweeleya zentsimbi egxininisiweyo yentsimbi ukuphumeza ukufuduswa kobushushu obukufutshane neqanda. Kwiziseko ezingundoqo ze-LNG, ezi nkqubo zinciphisa izinga lokubilisa imihla ngemihla ukuya ngaphantsi kwe-0.08%, xa kuthelekiswa ne-0.15% kwimibhobho eqhelekileyo ye-foam-insulated. Umzekelo, iprojekthi yeChevron's Gorgon LNG eOstreliya isebenzisa i-18 km ye-vacuum jacket efakwe umbhobho ukugcina amaqondo obushushu angama-162°C kuwo wonke ummandla wayo wokuthumela ngaphandle ngaphandle kwetheminali yonxweme, inciphisa ilahleko yamandla ngonyaka nge-6.2 yezigidi zeedola.

Imingeni ye-Arctic: Ii-VIP kwiindawo eziNgqongileyo

KuSingasiqithi weYamal waseSiberia, apho amaqondo obushushu ebusika ayehla aye kutsho ku-50°C.VIPamanethiwekhi ane-40-layer MLI (i-multilayer insulation) iqinisekisa ukuba i-LNG ihlala ikwimo engamanzi ngexesha le-2,000 km yokuthunyelwa kwempahla. Ingxelo ka-Rosneft ka-2023 ibalaselisa ukuba i-vacuum-insulated cryogenic piping yanciphisa ilahleko yokufunxa nge-53%, igcina i-120,000 yeetoni ze-LNG ngonyaka-elingana namandla amakhaya angama-450,000 aseYurophu.

Utshintsho lwexesha elizayo: Ukuguquguquka Kudibana noZinzo

Uyilo olusakhulayo oluxubileyo luyadibanisaimibhobho evacuum-insulatedkuqhagamshelwano lwemodyuli. Iziko le-Shell's Prelude FLNG kutshanje livavanywe ngamacangcivacuum-jacket imibhobho bhetyebhetye, ukufezekisa i-22% ngokukhawuleza ukulayisha ngokukhawuleza ngelixa ujongene noxinzelelo lwe-MPa ye-15. Ukongeza, iiprototypes ze-MLI eziphuculweyo zegraphene zibonisa amandla okuqhubela phambili ukucutha i-thermal conductivity ngama-30%, ngokuhambelana neethagethi zokunciphisa ukukhutshwa kwemethane ye-EU ka-2030.
