1 Mawu Oyamba
Makampani aku China a LNG apanga mndandanda wathunthu wamafakitale kuchokera ku liquefaction, mayendedwe, kutsika kwa gasi mpaka kugwiritsidwa ntchito, ndipo liwiro lachitukuko ndi kukhwima kwake zikukula bwino kwambiri, ndikuyika maziko abwino ogwiritsira ntchito gasi kunsi kwa mtsinje ku China. Pakalipano, malo okwana 14 a LNG a m'mphepete mwa nyanja amangidwa ndipo akumangidwa ku China, ndipo mphamvu zonse zolandirira zidzapitirira matani 50million / chaka zonse zikamalizidwa. Pali ma projekiti angapo omwe akugwira ntchito yoyambirira ⑴. Zomera zothirira madzi, ma satelayiti ndi magalimoto ndi zombo zowonjezera mafuta zikukulanso mwachangu. Pofika Meyi2013, malo opitilira 50 amadzimadzi amangidwa ndikuyamba kugwira ntchito m'dziko lonselo, ndi mphamvu yothira madzi okwanira 23million m3 / tsiku. Makhalidwe osungira a LNG pa -162 ℃ ndi kuthamanga kwanthawi zonse, mayendedwe apadera, kusintha kwamphamvu kwa tanki yosungira LNG panthawi yotsitsa ndi kudzaza, kutentha kwa tanki yosungiramo ndi mapaipi, ndi zina zotero, kutulutsa mpweya wochuluka wa vaporized, womwe ndi bog. Pofuna kuteteza ntchito yabwino komanso chitetezo cha zombo zoyendera, akasinja osungira ndi mapaipi, ndikofunikira kulingalira za chithandizo chamagulu ambiri ndikukhalabe ndi mphamvu zamagetsi kuti zisungidwe kupanikizika mkati mwazowongolera zotetezedwa. Choncho, pofuna chitetezo cha ntchito ndi kupulumutsa mphamvu, njira yochizira bog pansi pazikhalidwe zosiyanasiyana imaphunziridwa kuti ipititse patsogolo kuchira kwa bog ndi kuchepetsa kuwononga gasi.
2 njira kupanga
Pamalo olandila 4 x 160000m3, kuchuluka kwa evaporation tsiku ndi tsiku ndi 0 Malinga ndi kuwerengera kwa 05%, kutuluka kwa LNG tsiku lililonse kumakhala pafupifupi ma kiyubiki metres 320, ndipo bog yopangidwa ndi pafupifupi 192000 cubic metres, pafupifupi matani 144 / tsiku; Pansi pa chikhalidwe chotsitsa, kuchuluka kwa bogi komwe kumapangidwa ndi kusinthana kwa kutentha ndi kusintha kwamphamvu kudzakhala kangapo kapena ngakhale kakhumi kuposa momwe zimakhalira. Kuchiza bogi ndi njira yololera sikungangochepetsa kuwonongeka kwa zida ndi ogwira ntchito, komanso kupulumutsa mphamvu, kuchepetsa kumwa komanso kuchepetsa mtengo.
Kuti muphunzire njira ya chithandizo cha bog pansi pazikhalidwe zosiyanasiyana, kutenga malo olandirira ndi siteshoni ya satana monga chitsanzo, kusankhidwa kwa ndondomeko kumaganiziridwa kuchokera ku kuchuluka kwa bog. Tengani malo olandirira ku Fujian (4 x 160000m3 matanki osungira) ndi siteshoni ya satellite ku Shandong (10 100m3 matanki osungira). Maziko a fanizo: mitundu yosiyanasiyana ya matanki imakhala ndi mitundu yosiyanasiyana ya evaporation, ndipo njira zosiyanasiyana zochiritsira zidzakhudza kukonzedwanso kwa bog. Njira yoyenera yochizira imasankhidwa pamitundu yosiyanasiyana ya matanki ndi masikelo amankhwala a LNG.
3 ochiritsira mankhwala a Bog
Pali zambiri njira zinayi zochizira kwa bogi, imodzi ndi re condensation; Chachiwiri, psinjika mwachindunji; 3. Kuyaka kapena kutulutsa mpweya; Chachinayi, bwererani kwa chonyamulira cha LNG.
(1) Njira yothandizira kubwezeretsanso. Pambuyo podutsa mu thanki yolekanitsa ya gasi, bog imalowa mu bog compressor. Bogi yopanikizidwa imalowa mu Recondenser ndipo imasakanizidwa ndi LNG yotumizidwa kunja yomwe imakakamizidwa kuti ikhale yofanana. Bogiyo imafupikitsidwa ndi mphamvu yoziziritsa yomwe imatengedwa ndi LNG yotentha kwambiri ndikusakanikirana ndi LNG yodutsa mu mpope wopondereza kwambiri, kenako imatenthedwa ndi vaporizer ndikufalikira ku netiweki yapaipi yothamanga kwambiri (2). Chiwonetsero cha recondensation process of the terminal chikuwonetsedwa mu Chithunzi 1.
(2) Direct psinjika ndondomeko. Bog imatulutsidwa mwachindunji ku netiweki ya chitoliro pambuyo popanikizidwa ndi kompresa.
(3) Kuyaka moto kapena kutulutsa mpweya. Kuthamanga kwa thanki ndi kanyumba kukafika pamtengo wina, kuyaka kapena kuyaka moto nthawi zambiri kumatengedwa kuti achepetse kuthamanga kwa malo otetezeka komanso osinthika. Kuwotcha mpweya kapena kuyatsa moto kumakhala kuwononga kwambiri gasi wachilengedwe. Choncho, njira iyi ndi njira yotetezera chitetezo pakagwa mwadzidzidzi.
(4) Bog imasamutsidwa kupita ku sitima ya LNG kudzera mu mkono wobwerera kuti igwirizane ndi kupanikizika ndikudzaza vacuum yotulutsidwa ndi kutsitsa kwa thanki yosungirako LNG m'bwalo. Njirayi ndiyosavuta komanso yachangu, koma ndiyoyenera kutsitsa sitima yapamadzi ya LNG.
