Yini i-LNG Refueling Station?

Ngokukhuthazwa kancane kancane kokukhishwa kwekhabhoni ephansi, amazwe emhlabeni wonke nawo afuna imithombo yamandla engcono esikhundleni sikaphethiloli emkhakheni wezokuthutha. Ingxenye eyinhloko ye-liquefied natural gas (LNG) i-methane, okuyigesi yemvelo esiyisebenzisa ekuphileni kwethu kwansuku zonke. Empeleni iyigesi. Ngaphansi kwengcindezi evamile, ukuze kube lula ukuthuthwa nokugcinwa, igesi yemvelo ipholiswa ibe ngu-162 degrees Celsius, iguqule isuka esimweni esinegesi iye esimweni esiwuketshezi. Kuleli qophelo, umthamo wegesi yemvelo ewuketshezi cishe u-1/625 wevolumu yegesi yemvelo enesisindo esifanayo. Ngakho, yini isiteshi sokugcwalisa i-LNG? Lezi zindaba zizohlola isimiso sokusebenza, izici zokugcwalisa, kanye nendima ebalulekile eziyidlalayo kugagasi lamanje lokuguqulwa kwamandla.

Siyini isiteshi sokugcwalisa i-LNG?
Lona umshini okhethekile owenzelwe ukugcina nokufaka amafutha e-LNG. Ihlinzeka ikakhulukazi uphethiloli we-LNG wamaloli ahamba amabanga amade, amabhasi, amaloli asindayo noma imikhumbi. Ngokuhlukile eziteshini ezivamile zikaphethiloli nezadizili, lezi ziteshi zincibilikisa igesi yemvelo ebanda kakhulu (-162℃) ibe yisimo soketshezi, okwenza kube lula ukuyigcina nokuyihambisa.

Isitoreji: I-LNG ithuthwa ngamathangi e-cryogenic futhi igcinwe kumathangi e-vacuum ngaphakathi kweziteshi zokugcwalisa i-LNG ukuze kugcinwe izinga layo lokushisa eliphansi kanye nesimo soketshezi.

Ukufaka Uphethiloli: Uma kudingekile, sebenzisa iphampu ye-LNG ukudlulisa i-LNG isuka ethangini lokugcina iye emshinini wokugcwalisa uphethiloli. Abasebenzi abafaka uphethiloli baxhuma umlomo wombhobho womshini wokugcwalisa uphethiloli ethangini lokugcina le-LNG lemoto. Imitha yokugeleza ngaphakathi komshini wokugcwalisa i-refueling iqala ukulinganisa, futhi i-LNG iqala ukugcwaliswa ngaphansi kwengcindezi.

Yiziphi izingxenye eziyinhloko zesiteshi sokugcwalisa i-LNG?
Ithangi lokugcina i-vacuum enezinga lokushisa eliphansi: Ithangi lokugcina i-vacuum elinezingqimba ezimbili, elinganciphisa ukudluliswa kokushisa futhi ligcine izinga lokushisa lesitoreji se-LNG.

I-Vaporizer: Idivayisi eguqula i-LNG ewuketshezi ibe yi-CNG yegesi (i-re-gasification). Isetshenziselwa ikakhulukazi ukuhlangabezana nezidingo zokucindezela endaweni noma ukulawula ukucindezela kwamathangi okugcina.

I-Dispenser: Ifakwe i-interface yomsebenzisi ehlakaniphile, ifakwe ngaphakathi ngamapayipi, ama-nozzles okugcwalisa, amamitha okugeleza nezinye izingxenye eziklanyelwe ngokukhethekile i-LNG yezinga lokushisa eliphansi.

Uhlelo lokulawula: Izohlonyiswa ngohlelo lokuphatha oluhlakaniphile, oluphephile noludidiyelwe lokuqapha ingcindezi, izinga lokushisa lemishini ehlukahlukene esizeni, kanye nesimo sokusungula i-LNG.

Yimuphi umehluko phakathi kweziteshi zokugcwalisa i-LNG (i-liquefied natural gas) ne-CNG (igesi yemvelo ecindezelwe)?
I-Liquefied Natural Gas (LNG): Igcinwa isesimweni esiwuketshezi ekushiseni okungaba ngu-162 degrees Celsius. Ngenxa yesimo sayo esiwuketshezi, ithatha indawo encane futhi ingagcwaliswa emathangeni amaloli asindayo namaloli athwala impahla, okuvumela ukuhamba amabanga amade. Izici ezinjalo zenza kube ukukhetha okuthandwayo kwamabhasi ahamba amabanga amade namaloli asindayo.

Igesi Yemvelo Ecindezelwe (CNG): Igcinwe efomini legesi elinomfutho ophezulu. Njengoba kuyigesi, ithatha umthamo omkhulu futhi ngokuvamile idinga amasilinda egesi amakhulu noma ukugcwaliswa kaningi, okuyenza ifaneleke ezimotweni zamabanga amafushane njengamabhasi edolobha, izimoto ezizimele, njll.

Yiziphi izinzuzo zokusebenzisa i-liquefied natural gas (LNG)?
Ngokombono wemvelo, i-LNG ihambisana kakhulu nemvelo kunophethiloli. Nakuba izimoto ze-LNG zinezindleko zokuthenga eziphezulu zokuqala, ezidinga amathangi okugcina ama-cryogenic abizayo nezinjini ezikhethekile, izindleko zazo zikaphethiloli ziphansi kakhulu. Ngokuphambene, izimoto zikaphethiloli, nakuba zithengeka, zinezindleko zikaphethiloli eziphakeme futhi zithintwa ukuguquguquka kwentengo kawoyela yamazwe ngamazwe. Ngokombono wezomnotho, i-LNG inamandla amakhulu okuthuthuka.

Ingabe isiteshi sokugcwalisa igesi yemvelo ewuketshezi siphephile?
Impela. Izwe ngalinye linezindinganiso zokuklama ezihambisanayo zeziteshi zokuthela igesi yemvelo ewuketshezi, futhi amayunithi okwakha afanele kufanele alandele izindinganiso eziqinile zokwakha nokusebenza. I-LNG ngokwayo ngeke iqhume. Ngisho noma kunokuvuza kwe-LNG, izohlakazeka ngokushesha emkhathini futhi ngeke inqwabelane phansi futhi ibangele ukuqhuma. Ngesikhathi esifanayo, isiteshi sokuthela amafutha sizophinde samukele izindawo zokuphepha eziningi, ezingakwazi ukubona ngokuhlelekile ukuthi kukhona ukuvuza noma ukwehluleka kwemishini.
