Ezweni eliguquguqukayo le-Ukuthunyelwa kwe-LNG, lapho ukunemba nokuphepha kubaluleke kakhulu, ukuqapha ubuningi ngesikhathi sangempela kuyisici esibalulekile. NjengobaImakethe ye-LNGiyaqhubeka nokukhula, iqhutshwa yizinzuzo zayo zemvelo kanye nesidingo esikhulayo samafutha ahlanzekile, isidingo sokunembaUkulinganiswa kobuningi be-LNGisibaluleke kakhulu kunanini ngaphambili. Igesi yemvelo encibilikisiwe (i-LNG), egcinwe ku--162°C, iveza izinselele eziyingqayizivele ngenxa yokushintsha kokwakheka kwayo ngesikhathiUkuthuthwa kwe-LNG.I-Lonnmeter'sukuqamba izinto ezintshaamamitha obuningi obungaphakathiukubhekana nalezi zidingo, ukuqinisekisa ukusebenza kahle, ukuphepha, kanye nokuthobela imithethoIzinkampani zokuthumela izimpahla ze-LNG.
Isidingo Sokuqapha Ubuningi Obuqhubekayo
Ukuqapha okuqhubekayo kobuningi kubalulekile ukuvimbela izinkinga zokusebenza njengokungazinzi kwethangi kanye nokupompa okungasebenzi kahleUkuthunyelwa kwe-LNGUkuguquguquka kobuningi kungaholela ekuhlolweni kwempahla okunganembile, okungase kuholele ekungavumelanini kwezezimali noma ezingozini zokuphepha. Isibonelo, ukuhlukahluka kobuningi kungathinta ukuzinza kwamathangi okugcina i-LNG, okungabangela ukuhlukaniswa okuholela ezingozini eziyingozi zokugingqika. Ukupompa okungasebenzi kahle ngenxa yezinguquko zobuningi ezingaqaphelwanga nakho kungandisa izindleko zokusebenza kanye nesikhathi sokungasebenzi. Ngokusebenzisa isikhathi sangempelaUkulinganiswa kobuningi be-LNG,Izinkampani zokuthumela izimpahla ze-LNGbangaqinisekisa ukusebenza okuzinzile, banciphise izingozi, futhi balondoloze ukusebenza kahle kuzo zonke izindiza zabo.
Ukwanda Okusheshayo Kwemakethe ye-LNG
IImakethe ye-LNGibone ukukhula okuphawulekayo eminyakeni eyishumi edlule, iqhutshwa izinzuzo zayo zemvelo njengophethiloli wokuthutha. I-LNG ikhipha umsindo omncane futhi ine-CO2 ephansi uma iqhathaniswa nedizili, okwenza kube inketho ekhangayo yezokuthutha ezisindayo kanye nezicelo zezimboni. Imibiko yakamuva yemboni iqokomisa ukuthi imakethe yomhlaba wonke ye-LNG ikhula ngokushesha, kanti kulindeleke ukuthi inani elilinganayo legesi yemvelo lithuthwe ngamapayipi nangemikhumbi eminyakeni ezayo. Lokhu kukhula kugcizelela ukubaluleka kobuchwepheshe bokulinganisa obuthembekile ukusekela imigomo yokuzinza kwemboni kanye nokuhlangabezana nesidingo esikhulayo semithombo yamandla ehlanzekile.
Ukubaluleka Kokulinganisa Ubuningi Obunembile
KunembileUkulinganiswa kobuningi be-LNGkubalulekile ekuhwebeni, ekuthuthweni nasekuthuthweni kwe-LNG. Njengoba i-LNG ithengiswa ngokusekelwe kokuqukethwe kwayo kwamandla, kubalwa kusukela kuvolumu, ubuningi, kanye nenani lama-calories aphelele, ukulinganisa okunembile kubalulekile ukuze kwenziwe ukuthengiselana okufanele kanye nokusebenza kahle. Ukulinganisa ubuningi okusheshayo nokunembile kunenani elikhulu lezentengiselwano, okuqinisekisa ukuthi abahwebi kanyeIzinkampani zokuthumela izimpahla ze-LNGingahlola ngokuzethemba amandla adluliselwe ngesikhathi sokudluliselwa kwengane. Ukungalungi ekulinganisweni kobuningi kungaholela ekulahlekelweni kwezimali, ukungalandeli imithetho, noma izinselele zokusebenza, okugqamisa isidingo sezixazululo zokuqapha ezithuthukisiwe.
Izinselele Ekulinganisweni Kobuningi be-LNG
Izakhiwo eziyingqayizivele ze-LNG, okuhlanganisa izinga lokushisa layo eliphansi kakhulu elingu--162°C kanye nokushintsha kokwakheka kwayo ngesikhathiUkuthuthwa kwe-LNG, iveza izinselele ezinkulu zokulinganisa ubuningi. Ngesikhathi sokuthunyelwa, i-LNG idlula ekushiseni nasekushintsheni kokwakheka ngenxa yokushintsha kwezinga lokushisa kanye nengcindezi, okuthinta ngqo ubuningi bayo. Lezi zinguquko zenza ukuhlolwa kwe-metrological kube yinselele, njengoba izindlela zokulinganisa zendabuko zingase zingabi nomthelela oguquguqukayo we-LNG. Isibonelo, uhambo olude lwe-ballast lungashintsha kakhulu ukwakheka kanye nobuningi be-LNG, okudinga izixazululo zokuqapha ezithuthukisiwe, zesikhathi sangempela ezingazivumelanisa nalezi zimo ngenkathi zigcina ukunemba.
