1. Intshayelelo
Ishishini le-LNG laseTshayina lenze uthotho olupheleleyo lwemizi-mveliso ukusuka ekunyibilikiseni ulwelo, uthutho, ukufakelwa kwegesi kwisiphelo ukuya ekusetyenzisweni kwesiphelo, kwaye isantya sophuhliso kunye nokuvuthwa kwalo kuya kugqibelela ngakumbi, kubeka isiseko esihle sophuhliso sokusetyenziswa kwegesi yendalo ezantsi eTshayina. Okwangoku, izitishi ze-LNG ezili-14 ezikunxweme zakhiwe kwaye ziyakhiwa eTshayina, kwaye umthamo opheleleyo wokwamkela uya kudlula iitoni ezingama-50 ezigidi / ngonyaka emva kokuba zonke zigqityiwe. Kusekho inani leeprojekthi eziphantsi komsebenzi wokuqala ⑴. Izityalo zolwelo, izikhululo zesathelayithi kunye nokuzalisa izithuthi kunye neenqanawa nazo ziphuhliswa ngokukhawuleza. Ukususela ngoMeyi ka-2013, izityalo zolwelo ezingaphezu kwama-50 zakhiwe kwaye zaqaliswa ukusebenza kuzwelonke, ezinomthamo opheleleyo wolwelo we-23 yezigidi m3 / ngosuku. Iimpawu zokugcina i-LNG kwi -162 ℃ kunye noxinzelelo oluqhelekileyo, iimeko zothutho ezikhethekileyo, utshintsho loxinzelelo lwetanki yokugcina i-LNG ngexesha lokukhupha nokuzalisa, ukuvuza kobushushu kwitanki yokugcina kunye nemibhobho, njl.njl., kuya kuvelisa inani elikhulu legesi ephefumulayo, oko kukuthi i-bog. Ukuze kukhuselwe ukusebenza okuqhelekileyo kunye nokhuseleko lweenqanawa zothutho, iitanki zokugcina kunye nemibhobho, kuyimfuneko ukuqwalasela unyango lwenani elikhulu lee-bogs kunye nokugcina ibhalansi enamandla yoxinzelelo ukuze kugcinwe uxinzelelo ngaphakathi koluhlu lolawulo olukhuselekileyo. Ke ngoko, ngenjongo yokhuseleko lokusebenza kunye nokonga amandla, inkqubo yonyango lwe-bog phantsi kweemeko ezahlukeneyo ifundwa ukuphucula izinga lokubuyiselwa kwe-bog kunye nokunciphisa inkunkuma yegesi yendalo.
Uyilo lweendlela ezi-2
Kwisikhululo sokwamkela i-4 x 160000m3, izinga lokuphuma kwamanzi ngosuku yi-0 Ngokwendlela yokubala i-05%, ukuphuma kwamanzi kwi-LNG yemihla ngemihla kumalunga ne-320 cubic metres, kwaye i-bog eveliswayo imalunga ne-192000 cubic metres, malunga ne-144 tons / ngosuku; Phantsi kwemeko yokukhupha amanzi, ubungakanani be-bog eveliswa kukutshintshiselana kobushushu kunye notshintsho loxinzelelo luya kuba ngamaxesha amaninzi okanye aphindwe kalishumi kunaphantsi kwemeko yesiqhelo. Ukunyanga i-bog ngenkqubo efanelekileyo akunakunciphisa kuphela umonakalo onokubakho kwizixhobo nakubasebenzi, kodwa nakonga amandla, kunciphise ukusetyenziswa kwaye kunciphise iindleko.
Ukuze kufundwe inkqubo yonyango lwedama phantsi kweemeko ezahlukeneyo, xa kuthathwa isikhululo sokwamkela kunye nesikhululo sesathelayithi njengomzekelo, ukukhethwa kwenkqubo kuthathelwa ingqalelo kubungakanani bedama. Thatha isikhululo sokwamkela eFujian (itanki zokugcina ezi-4 x 160000m3) kunye nesikhululo sesathelayithi eShandong (itanki zokugcina ezili-10 eziyi-100m3). Isiseko sokufanisa: iintlobo ezahlukeneyo zeetanki zinezinga ezahlukeneyo zokufuma, kwaye iindlela ezahlukeneyo zonyango ziya kuchaphazela ukucutshungulwa okulandelayo kwedama. Inkqubo yonyango efanelekileyo iya kukhethwa kwiintlobo ezahlukeneyo zeetanki kunye nezikali zonyango lwe-LNG.
3 Unyango oluqhelekileyo lwe-bog
Ngokwesiqhelo kukho iindlela ezine zonyango lwe-bog eyenziweyo, enye kukubuyisela umswakama; eyesibini, ukucinezelwa ngokuthe ngqo; 3. Ukutsha okanye ukukhupha umoya; eyesine, ukubuyisela kwi-LNG carrier.
(1) Inkqubo yokulungisa ukufuma kwakhona. Emva kokudlula kwitanki yokwahlulahlula igesi nolwelo, ibhogi ingena kwi-compressor yebhogi. Ibhogi ecinezelweyo ingena kwi-Recondenser kwaye ixutywe ne-LNG ethunyelwe ngaphandle ecinezelweyo kuxinzelelo olufanayo. Ibhogi icinezelwe ngumthamo wokupholisa othwalwa yi-LNG epholileyo kwaye ixutywe ne-LNG by-pass kwimpompo yoxinzelelo oluphezulu, ize emva koko ifuthwe yi-vaporizer kwaye idluliselwe kwinethiwekhi yombhobho woxinzelelo oluphezulu (2). Itshathi yokuhamba kwenkqubo yokuphinda ifunyanwe yesiphelo iboniswe kuMfanekiso 1.
(2) Inkqubo yokucinezela ngokuthe ngqo. I-Bog ikhutshwa ngqo kwinethiwekhi yepayipi emva kokuba icinezelwe yi-compressor.
(3) Ukutsha okanye ukuvuthela umoya. Xa uxinzelelo olukwitanki nakwikhabhini lufikelela kwixabiso elithile, ukutsha komoya okanye ukuvuthela umoya kudla ngokusetyenziswa ukunciphisa uxinzelelo luye kuluhlu olukhuselekileyo nolulawulekayo. Ukutsha okanye ukuvuthela umoya kuya kuba yinkcitho enkulu yegesi yendalo. Ke ngoko, le ndlela yindlela yonyango lokhuseleko xa kukho imeko engxamisekileyo.
(4) I-Bog ithuthwa iye kwinqanawa ye-LNG ngengalo yokubuyisela ukuze ilinganise uxinzelelo kwaye izalise i-vacuum eveliswa kukukhutshwa kwetanki yokugcina i-LNG ebhodini. Le ndlela ilula kwaye iyakhawuleza, kodwa ifanelekile kuphela ekukhutshweni kwenqanawa ye-LNG.
