Makampani opanga LNG ku China apanga unyolo wathunthu wa mafakitale kuyambira pa kudzaza madzi, mayendedwe, kufalitsa mpweya wa terminal mpaka kugwiritsa ntchito magetsi, ndipo liwiro lake la chitukuko ndi kukhwima kwake zikukhala zangwiro kwambiri, zomwe zikuyika maziko abwino ogwiritsira ntchito gasi wachilengedwe ku China. Pakadali pano, malo 14 a LNG m'mphepete mwa nyanja amangidwa ndipo akumangidwa ku China, ndipo mphamvu yonse yolandirira idzapitirira matani 50 miliyoni / chaka chilichonse akamalizidwa. Palinso mapulojekiti angapo omwe akugwira ntchito yoyambirira ⑴. Malo opangira madzi, malo osungiramo zinthu za satellite ndi kudzaza mafuta kwa magalimoto ndi zombo nazonso zikukula mofulumira. Pofika mu Meyi 2013, malo opangira madzi opitilira 50 amangidwa ndikugwiritsidwa ntchito mdziko lonse, okhala ndi mphamvu yonse ya madzi okwana 23 miliyoni m3 / tsiku. Makhalidwe osungira LNG pa -162 ℃ ndi kupanikizika kwabwinobwino, mikhalidwe yapadera yoyendera, kusintha kwa mphamvu ya thanki yosungiramo LNG panthawi yotsitsa ndi kudzaza, kutuluka kwa kutentha kwa thanki yosungiramo ndi mapaipi, ndi zina zotero, zipanga mpweya wambiri wotentha, womwe ndi bog. Pofuna kuteteza kayendetsedwe kabwino ka sitima zoyendera, matanki osungiramo zinthu ndi mapaipi, ndikofunikira kuganizira za momwe mabowo ambiri amagwirira ntchito ndikusunga mphamvu kuti mphamvuyo ikhale yotetezeka. Chifukwa chake, pofuna chitetezo cha ntchito komanso kusunga mphamvu, njira yochizira mabowo m'mikhalidwe yosiyanasiyana imaphunziridwa kuti iwonjezere kubwezeredwa kwa mabowo ndikuchepetsa kutaya kwa mpweya wachilengedwe.
Kapangidwe ka njira ziwiri
Pa malo olandirira 4 x 160000m3, kuchuluka kwa nthunzi tsiku ndi tsiku ndi 0. Malinga ndi kuwerengera kwa 05%, nthunzi ya LNG tsiku ndi tsiku ndi pafupifupi 320 cubic metres, ndipo dambo lopangidwa ndi pafupifupi 192000 cubic metres, pafupifupi matani 144 patsiku; Pansi pa mkhalidwe wotsitsa, kuchuluka kwa dambo lopangidwa ndi kusintha kwa kutentha ndi kusintha kwa kuthamanga kwa mpweya kudzakhala kangapo kapena kupitirira khumi kuposa momwe zinalili kale. Kuchiza dambo ndi njira yoyenera sikungochepetsa kuwonongeka komwe kungachitike pazida ndi antchito, komanso kusunga mphamvu, kuchepetsa kugwiritsa ntchito ndikuchepetsa mtengo.
Pofuna kuphunzira njira yochizira bowa pansi pa mikhalidwe yosiyanasiyana, potengera malo olandirira ndi siteshoni ya satelayiti mwachitsanzo, kusankha njira kumaganiziridwa kuchokera ku kuchuluka kwa bowa. Tengani malo olandirira ku Fujian (matanki osungira 4 x 160000m3) ndi siteshoni ya satelayiti ku Shandong (matanki osungira 10 a 100m3). Maziko a fanizo: mitundu yosiyanasiyana ya matanki ili ndi kuchuluka kosiyana kwa nthunzi, ndipo njira zosiyanasiyana zochizira zidzakhudza kukonza bowa pambuyo pake. Njira yoyenera yochizira iyenera kusankhidwa pa mitundu yosiyanasiyana ya matanki ndi masikelo ochizira a LNG.
3 Chithandizo chachikhalidwe cha bog
Kawirikawiri pali njira zinayi zochizira bog yopangidwa, imodzi ndi kubwezeretsa condensation; yachiwiri, direct compression; 3. Kuyaka kapena kutulutsa mpweya; chachinayi, kubwezera ku LNG carrier.
(1) Njira yokonzanso kuzizira. Pambuyo podutsa mu thanki yolekanitsa gasi ndi madzi, bog imalowa mu compressor ya bog. Bog yopanikizika imalowa mu Recondenser ndipo imasakanizidwa ndi LNG yotumizidwa kunja yomwe imapanikizika ku mphamvu yomweyo. Bog imafupikitsidwa ndi mphamvu yozizira yomwe imanyamulidwa ndi LNG yoziziritsidwa kwambiri ndikusakanikirana ndi LNG by-pass mu pampu yamphamvu, kenako imatenthedwa ndi vaporizer ndikutumizidwa ku netiweki yapaipi yamphamvu kwambiri (2). Tchati cha kayendedwe ka redensation process cha terminal chikuwonetsedwa pa Chithunzi 1.
(2) Njira yokanikiza mwachindunji. Bog imatulutsidwa mwachindunji ku netiweki ya chitoliro pambuyo poti compressor yapanikizidwa.
(3) Kuwotcha kapena kutulutsa mpweya. Pamene kupanikizika mu thanki ndi kanyumba kafika pamlingo winawake, kuyaka kwa mpweya kapena kutulutsa mpweya nthawi zambiri kumagwiritsidwa ntchito kuti kuchepetse kuthamanga kwa mpweya kufika pamalo otetezeka komanso olamulirika. Kuwotcha kapena kutulutsa mpweya kudzakhala kutaya mpweya wachilengedwe kwambiri. Chifukwa chake, njira iyi ndi njira yotetezera pakagwa ngozi.
(4) Bog imatumizidwa ku sitima ya LNG kudzera mu mkono wobwerera kuti igwirizane ndi kupanikizika ndikudzaza vacuum yomwe imapangidwa potsitsa thanki yosungiramo LNG yomwe ili m'bwato. Njirayi ndi yosavuta komanso yachangu, koma ndi yoyenera kutsitsa sitima ya LNG yokha.
