I-LNG isifinyezo se-English Liquefied Natural Gas, okungukuthi, igesi yemvelo ewuketshezi.Kungumkhiqizo wokupholisa nokucwiliswa kwegesi yemvelo (i-methane CH4) ngemva kokuhlanzwa kanye nezinga lokushisa eliphansi kakhulu (-162°C, umfutho owodwa womkhathi).Umthamo wegesi yemvelo ewuketshezi uncishiswe kakhulu, cishe i-1/600 yomthamo wegesi yemvelo ku-0 ° C kanye nomfutho we-1 womkhathi, okusho ukuthi, ama-cubic metres angama-600 wegesi yemvelo angatholakala ngemuva kwe-cubic meter eyi-1 ye-LNG. igesi.
Igesi yemvelo ewuketshezi ayinambala futhi ayinaphunga, ingxenye enkulu i-methane, kukhona okunye ukungcola okumbalwa, ihlanzeke kakhulu.amandla.Ubuningi bayo obuwuketshezi bungaba ngu-426kg/m3, kanti ukuminyana kwegesi cishe ku-1.5 kg/m3.Umkhawulo wokuqhuma ngu-5% -15% (ivolumu%), futhi indawo yokuthungela icishe ibe ngu-450 °C.Igesi yemvelo ekhiqizwa insimu kawoyela / igesi yenziwa ngokususa uketshezi, i-asidi, ukomiswa, i-fractional distillation kanye ne-condensation yokushisa ephansi, futhi umthamo wehliswa ube ngu-1/600 wokuqala.
Ngokuthuthuka ngamandla komklamo wezwe lami othi “West-East Gas Pipeline”, ukushisa kuzwelonke kokusetshenziswa kwegesi yemvelo sekuqalile.Njengomthombo wamandla ongcono kakhulu emhlabeni, igesi yemvelo iye yaziswa kakhulu ekukhethweni kwemithombo yegesi yasemadolobheni ezweni lami, futhi ukukhuthazwa ngamandla kwegesi yemvelo kuye kwaba inqubomgomo yamandla yezwe lami.Kodwa-ke, ngenxa yesilinganiso esikhulu, ukutshalwa kwezimali okuphezulu kanye nesikhathi eside sokwakhiwa kwegesi yemvelo yokuthutha amapayipi amabanga amade, kunzima ukuthi amapayipi ahamba amabanga amade afinyelele emadolobheni amaningi ngesikhathi esifushane.
Ngokusebenzisa umfutho ophakeme, umthamo wegesi yemvelo uncishiswa izikhathi ezingaba ngu-250 (CNG) zokuthutha, bese indlela yokuyicindezela ixazulula inkinga yemithombo yegesi yemvelo kwamanye amadolobha.Ukusetshenziswa kobuchwepheshe besiqandisi sokushisa okuphansi kakhulu ukwenza igesi yemvelo ibe uketshezi (cishe izikhathi ezingama-600 ezincane ngomthamo), kusetshenziswa amathangi okugcina izinga lokushisa eliphansi kakhulu, ukuthutha igesi yemvelo amabanga amade ngezimoto, izitimela, imikhumbi, njll. , bese igcina futhi iphinde igcwalise i-LNG emathangini okugcina abandayo okushisa aphansi kakhulu Uma iqhathaniswa nemodi ye-CNG, imodi yokuhlinzeka ngegesi inokusebenza kahle kokudlulisela, ukuphepha okuqinile nokwethembeka, futhi ingaxazulula kangcono inkinga yemithombo yegesi yemvelo yasemadolobheni.
Izimpawu ze-LNG
1. Izinga lokushisa eliphansi, isilinganiso esikhulu sokunwetshwa kwegesi-uketshezi, ukusebenza kahle kwamandla, ukuthutha nokugcina kulula.
I-cubic meter ejwayelekile yegesi yemvelo inesisindo esishisayo esingaba ngu-9300 kcal
I-1 ton ye-LNG ingakhiqiza i-1350 cubic metres ejwayelekile yegesi yemvelo, engakhiqiza ama-degree angu-8300 kagesi.
2. Amandla ahlanzekile - i-LNG ithathwa njengamandla ezinsalela ahlanzekile emhlabeni!
Okuqukethwe kwesibabule se-LNG kuphansi kakhulu.Uma izigidi ezingu-2.6 zamathani/ngonyaka we-LNG zisetshenziselwa ukukhiqiza amandla, izonciphisa ukukhishwa kwe-SO2 ngamathani angaba ngu-450,000 (cishe ilingane nokuphindwe kabili ukukhishwa kwe-SO2 yonyaka e-Fujian) uma kuqhathaniswa namalahle (lignite).Misa ukunwetshwa komkhuba wemvula ene-asidi.
Ukukhiqizwa kwamandla egesi yemvelo i-NOX kanye ne-CO2 kungama-20% kuphela kanye nama-50% ezitshalo zamandla aphehlwa ngamalahle
Ukusebenza okuphezulu kokuphepha - kunqunywa izici ezinhle kakhulu zomzimba namakhemikhali ze-LNG!Ngemuva kwe-gasification, ilula kunomoya, ayinambala, ayinaphunga futhi ayinabuthi.
Iphuzu eliphezulu lokuthungela: izinga lokushisa elizenzakalelayo lingaba ngu-450 ℃;ububanzi bokuvutha obuncane: 5% -15%;ilula kunomoya, kulula ukuyisakaza!
Njengomthombo wamandla, i-LNG inezici ezilandelayo:
I-LNG empeleni ayikhiqizi ukungcola ngemva kokusha.
Ukuthembeka kokuhlinzekwa kwe-LNG kuqinisekiswa yinkontileka nokusebenza kwalo lonke iketango.
Ukuphepha kwe-LNG kuqinisekiswa ngokugcwele ngokusebenzisa ngokuqinile uchungechunge lwamazinga omhlaba ekwakhiweni, ukwakhiwa kanye nenqubo yokukhiqiza.I-LNG isisebenze iminyaka engu-30 ngaphandle kwengozi embi.
I-LNG, njengomthombo wamandla wokuphehla ugesi, ihambisana nokulawulwa okuphezulu, ukusebenza okuphephile kanye nokwenza kahle kwegridi kagesi kanye nokuthuthukiswa kwesakhiwo sokuphakelwa kukagesi.
Njengamandla asemadolobheni, i-LNG ingathuthukisa kakhulu ukuzinza, ukuphepha kanye nomnotho wokuhlinzekwa kwegesi.
Ibanga elibanzi lokusetshenziswa kwe-LNG
Njengophethiloli ohlanzekile, i-LNG izoba ngomunye wemithombo yamandla eyinhloko kuleli khulu leminyaka elisha.Chaza ukusetshenziswa kwayo, ikakhulukazi okuhlanganisa:
Inani eliphakeme kakhulu kanye nokushefa okuphezulu kwengozi okusetshenziselwa ukuhlinzekwa kwegesi yasemadolobheni
Isetshenziswa njengomthombo omkhulu wegesi wokuphakelwa kwegesi yamapayipi emadolobheni amakhulu namaphakathi
Isetshenziswa njengomthombo wegesi wokufakwa kwegesi komphakathi we-LNG
Isetshenziswa njengamafutha okugcwalisa imoto
esetshenziswa njengamafutha endiza
Ukusetshenziswa kwamandla abandayo kwe-LNG
Isistimu Yamandla Esabalalisiwe
