Yaabka Injineernimada ee tuubo jaakad faakiyuum ah

Tuubbo dahaaran oo faakuumka ah(VIP), oo sidoo kale loo yaqaan tuubo faakiyuum ah oo jaakadaysan (VJP), waxay isticmaashaa faakiyuum sare (10⁻⁶ Torr) oo u dhexeeya lakabyada birta aan miridhku lahayn ee isku xiran si loo gaaro wareejinta kulaylka ku dhawaad ​​eber. Kaabayaasha LNG, nidaamyadani waxay yareeyaan heerarka karkarinta maalinlaha ah ilaa ka hooseeya 0.08%, marka la barbar dhigo 0.15% tuubooyinka caadiga ah ee lagu dahaadhay xumbo. Tusaale ahaan, mashruuca Chevron's Gorgon LNG ee Australia wuxuu shaqaaleysiiyaa 18 km oo tuubo faakiyuum ah si uu u ilaaliyo heerkulka -162°C ee marinkeeda dhoofinta xeebaha, isagoo dhimaya khasaaraha tamarta sanadlaha ah $6.2 milyan.

Caqabadaha Arctic: VIP-yada ku sugan Deegaannada Ba'an

Jasiiradda Yamal ee Siberia, halkaas oo heerkulka jiilaalku uu hoos ugu dhaco -50°C,VIP-dashabakadaha leh MLI 40-lakab ah (dahaarka lakabka badan leh) waxay hubiyaan in LNG uu ku sii jiro qaab dareere ah inta lagu jiro 2,000 km oo shixnadaha la wareejinayo. Warbixinta Rosneft ee 2023 waxay iftiiminaysaa in tuubooyinka cryogenic-ka ee faakuumka lagu dahaadhay ay hoos u dhigeen khasaaraha uumiga 53%, taasoo badbaadisay 120,000 oo tan oo LNG ah sannadkii - taasoo u dhiganta korontada 450,000 oo guri oo Yurub ah.

Hal-abuurrada Mustaqbalka: Dabacsanaanta waxay la jaanqaadaysaa waarta

Naqshadaha isku-dhafka ah ee soo baxaya ayaa isku dhafantuubooyinka faakiyuumka lagu dahaadhayisku xirka modular-ka. Xarunta FLNG ee Shell ee Prelude ayaa dhawaan tijaabisay jiingadotuubooyin dabacsan oo jaakad faakiyuum ah, oo gaaraya 22% xawaare rarid oo dhakhso badan iyadoo la iska ilaalinayo cadaadiska 15 MPa. Intaa waxaa dheer, noocyada MLI ee lagu xoojiyay graphene waxay muujinayaan awood ay ku sii dhimi karaan kulaylka 30%, iyagoo la jaan qaadaya bartilmaameedyada yaraynta qiiqa methane ee Midowga Yurub ee 2030.
