LNG ndi chidule cha English Liquefied Natural Gas, ndiko kuti, gasi wachilengedwe wokhala ndi liquefied.Zimapangidwa ndi kuziziritsa ndi kukhetsa gasi (methane CH4) pambuyo pa kuyeretsedwa ndi kutentha kwambiri (-162 ° C, kuthamanga kwa mumlengalenga umodzi).Kuchuluka kwa gasi wachilengedwe wosungunuka kumachepetsedwa kwambiri, pafupifupi 1/600 ya kuchuluka kwa gasi wachilengedwe pa 0 ° C ndi 1 mpweya wa mpweya, ndiye kuti, ma cubic metres 600 a gasi wachilengedwe amatha kupezeka pambuyo pa 1 kiyubiki mita ya LNG. mpweya.
Gasi wachilengedwe wopanda mtundu komanso wopanda fungo, gawo lalikulu ndi methane, pali zonyansa zina zochepa, ndizoyera kwambiri.mphamvu.Kachulukidwe ake amadzimadzi ndi pafupifupi 426kg/m3, ndipo kachulukidwe ka gasi ndi pafupifupi 1.5 kg/m3.Malire ophulika ndi 5% -15% (volume%), ndipo poyatsira moto ndi pafupifupi 450 ° C.Gasi wachilengedwe wopangidwa ndi malo opangira mafuta / gasi amapangidwa pochotsa madzi, asidi, kuyanika, distillation yagawo ndi kutentha kwapang'onopang'ono, ndipo voliyumuyo imachepetsedwa kukhala 1/600 yapachiyambi.
Ndi chitukuko champhamvu cha pulojekiti ya dziko langa ya “West-East Gas Pipeline”, kutentha kwa dziko kugwiritsiridwa ntchito kwa gasi kwayambika.Monga gwero labwino kwambiri lamagetsi padziko lapansi, gasi lachilengedwe lakhala lofunika kwambiri pakusankha magwero a gasi m'tauni m'dziko langa, ndipo kukwezedwa mwamphamvu kwa gasi kwakhala lamulo lamphamvu mdziko langa.Komabe, chifukwa cha kuchuluka kwakukulu, ndalama zambiri komanso nthawi yayitali yomanga mapaipi achilengedwe a gasi wamtunda wautali, zimakhala zovuta kuti mapaipi akutali afikire mizinda yambiri munthawi yochepa.
Pogwiritsa ntchito kuthamanga kwakukulu, kuchuluka kwa gasi wachilengedwe kumachepetsedwa pafupifupi nthawi za 250 (CNG) poyendetsa, ndiyeno njira yochepetsera nkhawa imathetsa vuto la magwero a gasi m'mizinda ina.Kugwiritsa ntchito ukadaulo wamafiriji otsika kwambiri kuti apange gasi wachilengedwe kukhala wamadzimadzi (pafupifupi nthawi 600 kucheperako), pogwiritsa ntchito akasinja osungira ozizira kwambiri, kunyamula gasi wachilengedwe mtunda wautali ndi magalimoto, masitima apamadzi, zombo, ndi zina zambiri. , ndiyeno kusunga ndi regasifying LNG mu kopitilira muyeso-otsika kutentha ozizira akasinja Poyerekeza ndi CNG akafuna, mpweya kupereka mode ali apamwamba kufala Mwachangu, chitetezo champhamvu ndi kudalirika, ndipo akhoza bwino kuthetsa vuto la magwero achilengedwe gasi m'tauni.
Zithunzi za LNG
1. Kutentha kochepa, chiŵerengero chachikulu cha gasi-madzimadzi owonjezera, mphamvu zowonjezera mphamvu, zosavuta kunyamula ndi kusunga.
1 muyezo wa kiyubiki mita wa gasi wachilengedwe uli ndi mphamvu yotentha pafupifupi 9300 kcal
1 tani ya LNG imatha kupanga 1350 muyezo wa kiyubiki mita wa gasi wachilengedwe, womwe umatha kupanga madigiri 8300 amagetsi.
2. Mphamvu yoyera - LNG imatengedwa kuti ndiyo mphamvu yoyera kwambiri padziko lapansi!
Sulfure ya LNG ndiyotsika kwambiri.Ngati matani 2.6 miliyoni / chaka cha LNG agwiritsidwa ntchito popanga magetsi, achepetsa mpweya wa SO2 ndi matani pafupifupi 450,000 (pafupifupi ofanana ndi kuwirikiza kawiri pachaka kwa SO2 mpweya ku Fujian) poyerekeza ndi malasha (lignite).Letsani kufalikira kwa mvula ya asidi.
Kutulutsa mphamvu kwa gasi wachilengedwe NOX ndi CO2 ndi 20% ndi 50% yokha yamagetsi opangira malasha.
Kuchita bwino kwachitetezo - kumatsimikiziridwa ndi mawonekedwe abwino kwambiri akuthupi ndi mankhwala a LNG!Pambuyo pa gasification, imakhala yopepuka kuposa mpweya, yopanda mtundu, yopanda fungo komanso yopanda poizoni.
High poyatsira mfundo: auto-poyaka kutentha ndi za 450 ℃;yopapatiza kuyaka osiyanasiyana: 5% -15%;chopepuka kuposa mpweya, chosavuta kufalitsa!
Monga gwero lamphamvu, LNG ili ndi izi:
LNG kwenikweni sipangitsa kuipitsa pambuyo kuyaka.
Kudalirika kwa kupezeka kwa LNG kumatsimikiziridwa ndi mgwirizano ndi ntchito ya unyolo wonse.
Chitetezo cha LNG chimatsimikiziridwa kwathunthu ndikutsata mosamalitsa miyezo yapadziko lonse lapansi pakupanga, kumanga ndi kupanga.LNG yakhala ikugwira ntchito kwa zaka 30 popanda ngozi yowopsa.
LNG, monga gwero la mphamvu zopangira magetsi, imathandizira pakuwongolera bwino kwambiri, kugwira ntchito motetezeka komanso kukhathamiritsa kwa gridi yamagetsi ndikuwongolera mawonekedwe amagetsi.
Monga mphamvu zamatawuni, LNG imatha kusintha kwambiri kukhazikika, chitetezo komanso chuma cha gasi.
Zambiri zogwiritsa ntchito LNG
Monga mafuta oyera, LNG idzakhala imodzi mwazinthu zazikulu zopangira mphamvu m'zaka zatsopano.Fotokozani ntchito zake, makamaka kuphatikiza:
Kuchulukitsitsa kwapamwamba komanso kumeta kwangozi komwe kumagwiritsidwa ntchito popereka gasi wakutawuni
Amagwiritsidwa ntchito ngati gwero lalikulu la gasi popereka gasi m'mizinda ikuluikulu ndi yapakati
Imagwiritsidwa ntchito ngati gwero la gasi popanga gasi ku gulu la LNG
Amagwiritsidwa ntchito ngati mafuta opangira mafuta m'galimoto
amagwiritsidwa ntchito ngati mafuta a ndege
Kugwiritsa ntchito mphamvu zozizira kwa LNG
