I-LNG sisishunqulelo se-English Liquefied Natural Gas, oko kukuthi, i-liquefied natural gas.Yimveliso yokupholisa kunye ne-liquefaction yegesi yendalo (i-methane CH4) emva kokucoca kunye neqondo lokushisa eliphantsi kakhulu (-162 ° C, uxinzelelo lwe-atmospheric enye).Umthamo wegesi yendalo enolwelo uncitshiswe kakhulu, malunga ne-1/600 yomthamo wegesi yendalo kwi-0 ° C kunye noxinzelelo lwe-1 emoyeni, oko kukuthi, i-600 cubic metres yegesi yendalo inokufumaneka emva kwe-1 cubic meter ye-LNG. igasified.
Irhasi yendalo enyibilikisiweyo ayinambala kwaye ayinavumba, eyona nto iphambili yimethane, zimbalwa ezinye izinto ezimdaka, icoceke kakhulu.amandla.Ubuninzi bayo be-liquid malunga ne-426kg / m3, kwaye ubuninzi begesi bu malunga ne-1.5 kg / m3.Umda wokudubula yi-5% -15% (umthamo%), kwaye indawo yokutshisa imalunga ne-450 °C.Igesi yendalo eveliswa yintsimi yeoli / igesi yenziwe ngokususa ulwelo, i-asidi, ukomisa, i-distillation ye-fractional kunye ne-condensation ephantsi yokushisa, kwaye umthamo uyancipha ukuya kwi-1/600 ye-original.
Ngophuhliso olomeleleyo lweprojekthi yelizwe lam “yoMbhobho werhasi okwiNtshona-Mpuma”, ubushushu besizwe bokusetyenziswa kwerhasi yendalo buqalisiwe.Njengowona mthombo wamandla ungcono kwihlabathi, igesi yendalo ixabiswe kakhulu ekukhetheni imithombo yegesi yasezidolophini kwilizwe lam, kwaye ukukhuthazwa ngamandla kwegesi yendalo kuye kwaba ngumgaqo-nkqubo wamandla welizwe lam.Nangona kunjalo, ngenxa yomlinganiselo omkhulu, utyalo-mali oluphezulu kunye nexesha elide lokwakhiwa kwerhasi yendalo yokuthutha imibhobho yomgama omde, kunzima ukuba imibhobho emide ifikelele kwizixeko ezininzi ngexesha elifutshane.
Ukusebenzisa uxinzelelo oluphezulu, umthamo wegesi yendalo uyancitshiswa malunga namaxesha angama-250 (CNG) ukuthutha, kwaye ke indlela yokuyidambisa isombulula ingxaki yemithombo yegesi yendalo kwezinye izixeko.Ukusetyenziswa kwetekhnoloji yefriji yobushushu obuphantsi kakhulu ukwenza irhasi yendalo ibe kwimeko yolwelo (malunga namaxesha angama-600 amancinci ngomthamo), kusetyenziswa iitanki zokugcina ubushushu obuphantsi kakhulu, ukuthutha igesi yendalo kumgama omde ngezithuthi, oololiwe, iinqanawa, njl. , kwaye emva koko ugcine kwaye uphinde uhlaziye i-LNG kwiitanki zokugcina ezibandayo ze-ultra-low xa kuthelekiswa nemo ye-CNG, imowudi yokubonelela ngegesi inokuhanjiswa okuphezulu, ukhuseleko olunamandla kunye nokuthembeka, kwaye inokusombulula ngcono ingxaki yemithombo yegesi yendalo yasezidolophini.
Iimpawu zeLNG
1. Ubushushu obuphantsi, umlinganiselo omkhulu wokwandiswa kwegesi-ulwelo, ukusebenza kakuhle kwamandla, kulula ukuthutha nokugcina.
I-1 standard cubic meter yegesi yendalo inobunzima bokushisa obumalunga ne-9300 kcal
I-1 toni ye-LNG inokuvelisa i-1350 ye-cubic metres eqhelekileyo yegesi yendalo, enokuvelisa i-8300 degrees yombane.
2. Amandla acocekileyo - i-LNG ithathwa njengawona mandla acocekileyo emhlabeni!
Umxholo wesulfure we-LNG uphantsi kakhulu.Ukuba i-2.6 yezigidi zeetoni / ngonyaka we-LNG isetyenziselwa ukuvelisa umbane, iya kunciphisa ukukhutshwa kwe-SO2 malunga neetoni ezingama-450,000 (ngokuqikelelwa ngokulingana nokukhutshwa kwe-SO2 yonyaka eFujian) xa kuthelekiswa namalahle (lignite).Misa ukwanda kwendlela yemvula eneasidi.
Ukuveliswa kwamandla erhasi yendalo i-NOX kunye ne-CO2 yi-20% kuphela kunye ne-50% yezixhobo zombane ezibaswa ngamalahle.
Ukusebenza kokhuseleko oluphezulu-kugqitywe ngeempawu ezibalaseleyo zomzimba kunye neekhemikhali ze-LNG!Emva kwe-gasification, ilula kunomoya, ayinambala, ayinavumba kwaye ayinayo ityhefu.
Indawo yokutshisa ephezulu: iqondo lobushushu elizenzekelayo limalunga ne-450 ℃;uluhlu lokutsha olumxinwa: 5% -15%;Ikhaphukhaphu kunomoya, kulula ukuyisasaza!
Njengomthombo wamandla, i-LNG inezi mpawu zilandelayo:
I-LNG ngokusisiseko ayivelisi ungcoliseko emva kokutsha.
Ukuthembeka kokunikezelwa kwe-LNG kuqinisekiswa yinkontileka kunye nokusebenza kwekhonkco lonke.
Ukhuseleko lwe-LNG luqinisekiswa ngokupheleleyo ngokuphumeza ngokungqongqo uluhlu lwemigangatho yamazwe ngamazwe kuyilo, ukwakhiwa kunye nenkqubo yokuvelisa.I-LNG isebenze iminyaka engama-30 ngaphandle kwengozi enkulu.
I-LNG, njengomthombo wamandla wokuvelisa amandla, ifanelekile kulawulo oluphezulu, ukusebenza ngokukhuselekileyo kunye nokuphucula igridi yamandla kunye nokuphuculwa kobume bokubonelela umbane.
Njengamandla asezidolophini, i-LNG inokuphucula kakhulu uzinzo, ukhuseleko kunye noqoqosho lonikezelo lwegesi.
Uluhlu olubanzi losetyenziso lwe-LNG
Njengombane ococekileyo, i-LNG ngokuqinisekileyo iya kuba ngomnye wemithombo yamandla ephambili kwinkulungwane entsha.Chaza ukusetyenziswa kwayo, ngakumbi kubandakanya:
Incopho yomthwalo kunye nokuchetywa kwengozi kusetyenziswe ukubonelela ngerhasi yasezidolophini
Isetyenziswa njengowona mthombo werhasi ophambili wonikezelo lwerhasi yombhobho kwizixeko ezikhulu neziphakathi
Isetyenziswa njengomthombo wegesi wokufakwa kwegesi kuluntu lwe-LNG
Isetyenziswa njengamafutha okugalela imoto
esetyenziswa njengamafutha enqwelomoya
Ukusetyenziswa kwamandla abandayo e-LNG
Inkqubo yaMandla asasazwayo
