Iyini isiteshi sokuthela uphethiloli se-LNG?

Ngokukhuthazwa kancane kancane kokukhishwa kwegesi ephansi, amazwe emhlabeni wonke nawo afuna imithombo yamandla engcono yokufaka esikhundleni sikaphethiloli emkhakheni wezokuthutha. Ingxenye eyinhloko yegesi yemvelo encibilikisiwe (i-LNG) yi-methane, okuyigesi yemvelo esiyisebenzisayo ekuphileni kwethu kwansuku zonke. Empeleni iyigesi. Ngaphansi kwengcindezi evamile, ukuze kube lula ukuthuthwa nokugcinwa kwayo, igesi yemvelo ipholiswa ibe ngaphansi kwama-degree Celsius angu-162, iguquke isuke esimweni segesi iye esimweni soketshezi. Kuleli qophelo, umthamo wegesi yemvelo encibilikisiwe cishe u-1/625 wevolumu yegesi yemvelo yegesi enobunzima obufanayo. Ngakho-ke, siyini isiteshi sokugcwalisa i-LNG? Lezi zindaba zizohlola isimiso sokusebenza, izici zokugcwalisa, kanye nendima ebalulekile eyidlalayo kugagasi lokuguqulwa kwamandla lamanje.

Iyini isiteshi sokugcwalisa uphethiloli se-LNG?
Lena imishini ekhethekile eyenzelwe ukugcina nokugcwalisa i-LNG. Ihlinzeka kakhulu ngophethiloli we-LNG wamaloli emithwalo ahamba ibanga elide, amabhasi, amaloli asindayo noma imikhumbi. Ngokungafani neziteshi zikaphethiloli nezedizili ezivamile, lezi ziteshi zincibilikisa igesi yemvelo ebanda kakhulu (-162℃) ibe yisimo soketshezi, okwenza kube lula ukuyigcina nokuyithutha.

Isitoreji: I-LNG ithuthwa ngamathangi e-cryogenic futhi igcinwe emathangini angenawo umoya ngaphakathi kweziteshi zokugcwalisa ze-LNG ukuze igcine izakhiwo zayo zomzimba ezisezingeni eliphansi lokushisa kanye nesimo soketshezi.

Ukugcwalisa Uphethiloli: Uma kudingeka, sebenzisa iphampu ye-LNG ukuze udlulise i-LNG isuka ethangini lokugcina impahla iye emshinini wokugcwalisa uphethiloli. Abasebenzi bokugcwalisa uphethiloli baxhuma i-nozzle yomshini wokugcwalisa uphethiloli ethangini lokugcina i-LNG lemoto. Imitha yokuhamba ngaphakathi komshini wokugcwalisa uphethiloli iqala ukulinganisa, bese i-LNG iqala ukugcwalisa uphethiloli ngaphansi kwengcindezi.

Yiziphi izingxenye eziyinhloko zesiteshi sokugcwalisa i-LNG?
Ithangi lokugcina i-vacuum elinokushisa okuphansi: Ithangi lokugcina i-vacuum elinongqimba oluphindwe kabili, elinganciphisa ukudluliselwa kokushisa futhi ligcine izinga lokushisa lokugcina le-LNG.

I-Vaporizer: Idivayisi eguqula i-LNG ewuketshezi ibe yi-CNG yegesi (ukuvuselelwa kabusha kwegesi). Isetshenziswa kakhulu ukuhlangabezana nezidingo zokucindezela endaweni noma ukulawula ukucindezela kwamatangi okugcina.

I-Dispenser: Ifakwe isikhombimsebenzisi esihlakaniphile, ifakwe ngaphakathi ngamapayipi, ama-nozzle okugcwalisa, amamitha okugeleza kanye nezinye izingxenye ezenzelwe ngokukhethekile i-LNG enokushisa okuphansi.

Uhlelo lokulawula: Luzohlonyiswa ngohlelo lokuphatha oluhlakaniphile, oluphephile noluhlanganisiwe lokuqapha ingcindezi, izinga lokushisa lemishini ehlukahlukene endaweni, kanye nesimo sempahla ye-LNG.

Yimuphi umehluko phakathi kweziteshi zokugcwalisa uphethiloli ze-LNG (liquefied natural gas) kanye neziteshi zokugcwalisa uphethiloli ze-CNG (compressed natural gas)?
Igesi Yemvelo Encibilikisiwe (LNG): Igcinwa isesimweni soketshezi ekushiseni okungama-degree Celsius angu-162 ngaphansi. Ngenxa yesimo sayo soketshezi, ithatha isikhala esincane futhi ingagcwaliswa emathangini amaloli asindayo namaloli empahla, okuvumela ukuhamba ibanga elide. Izici ezinjalo ziyenza ibe ukukhetha okuthandwayo kwamabhasi ahamba ibanga elide namaloli asindayo.

Igesi Yemvelo Ecindezelwe (CNG): Igcinwa ngesimo segesi enomfutho ophezulu. Njengoba iyigesi, ithatha umthamo omkhulu futhi ngokuvamile idinga amasilinda egesi amakhulu asebhodini noma ukugcwalisa kaningi, okwenza ifaneleke ezimotweni ezikude njengamabhasi asedolobheni, izimoto zangasese, njll.

Yiziphi izinzuzo zokusebenzisa igesi yemvelo encibilikisiwe (i-LNG)?
Ngokombono wezemvelo, i-LNG inobungani kakhulu nemvelo kunophethiloli. Nakuba izimoto ze-LNG zinezindleko zokuthenga zokuqala eziphezulu, ezidinga amathangi okugcina abizayo e-cryogenic kanye nezinjini ezikhethekile, izindleko zazo zikaphethiloli ziphansi kakhulu. Ngokuphambene nalokho, izimoto zikaphethiloli, nakuba zingabizi kakhulu, zinezindleko zikaphethiloli eziphakeme futhi zithinteka ukuguquguquka kwamanani kaphethiloli wamazwe ngamazwe. Ngokombono wezomnotho, i-LNG inamandla amakhulu okuthuthukiswa.

Ingabe isiteshi sokugcwalisa uphethiloli wemvelo esinoketshezi siphephile?
Ngokuqinisekile. Izwe ngalinye linezindinganiso zokuklama ezihambisanayo zeziteshi zokugcwalisa uphethiloli wemvelo ezimanzi, futhi amayunithi okwakha afanele kumele alandele izindinganiso eziqinile zokwakha nokusebenza. I-LNG ngokwayo ngeke iqhume. Ngisho noma kukhona ukuvuza kwe-LNG, izonyamalala ngokushesha emkhathini futhi ngeke iqoqeke phansi futhi ibangele ukuqhuma. Ngesikhathi esifanayo, isiteshi sokugcwalisa uphethiloli sizophinde samukele izikhungo eziningi zokuphepha, ezingakwazi ukubona ngokuhlelekile ukuthi kukhona ukuvuza noma ukwehluleka kwemishini.
