Emhlabeni oguquguqukayo weUkuthunyelwa kwe-LNG, lapho ukunemba nokuphepha kubaluleke kakhulu, ukuqapha ukuminyana kwesikhathi sangempela kuyingxenye ebalulekile. Njengoba iImakethe ye-LNGiyaqhubeka nokukhula, iqhutshwa izinzuzo zayo zemvelo kanye nesidingo esikhulayo samafutha ahlanzekile, isidingo sokunembaIsilinganiso sokuminyana kwe-LNGselibaluleke kakhulu kunangaphambili. I-Liquefied natural gas (LNG), egcinwe ku--162°C, iveza izinselelo eziyingqayizivele ngenxa yokushintsha kokwakheka kwayo ngesikhathi.Ezokuthutha ze-LNG.Izindawo zokuhlala e- Lonnmeterezintshaamamitha wokuminyana emgqeniukubhekana nalezi zidingo, kuqinisekiswe ukusebenza kahle, ukuphepha, kanye nokuhambisana kweIzinkampani zokuthumela i-LNG.
Isidingo Sokuqapha Ukuminyana Okuqhubekayo
Ukuqapha okuqhubekayo kokuminyana kubalulekile ukuze kuvinjwe izinkinga zokusebenza njengokungaqini kahle kwethangi nokumpompa ukungasebenzi kahle.Ukuthunyelwa kwe-LNG. Ukushintshashintsha kokuminyana kungaholela ekuhlolweni kwempahla okungalungile, okungase kubangele ukungafani kwezezimali noma izingozi zokuphepha. Isibonelo, ukuhlukahluka kokuminyana kungathinta ukuzinza kwamathangi okugcina e-LNG, okungase kubangele ukuhlukaniswa okuholela ezingozini eziyingozi zokugingqika. Ukupompa okunganele ngenxa yezinguquko zokuminyana okungagadiwe nakho kungakhuphula izindleko zokusebenza kanye nesikhathi sokuphumula. Ngokusebenzisa isikhathi sangempelaIsilinganiso sokuminyana kwe-LNG,Izinkampani zokuthumela i-LNGingaqinisekisa ukusebenza okuzinzile, inciphise ubungozi, futhi igcine ukusebenza kahle kuyo yonke imikhumbi yabo.
Ukukhula Okusheshayo Kwemakethe ye-LNG
IImakethe ye-LNGibone ukukhula okumangalisayo kule minyaka eyishumi edlule, iqhutshwa izinzuzo zayo zemvelo njengophethiloli wezokuthutha. I-LNG ikhipha umsindo omncane futhi ine-CO2 footprint ephansi uma kuqhathaniswa nodizili, okuyenza ibe inketho ekhangayo kwezokuthutha ezisindayo nasezimbonini. Imibiko yakamuva yezimboni igqamisa ukuthi imakethe ye-LNG yomhlaba wonke ikhula ngokushesha, ngamanani alinganayo egesi yemvelo okulindeleke ukuthi ithuthwe ngamapayipi nangomkhumbi eminyakeni ezayo. Lokhu kukhula kugcizelela ukubaluleka kobuchwepheshe bokulinganisa obuthembekile ukuze kusekelwe izinjongo zokusimama kwemboni kanye nokuhlangabezana nesidingo esikhulayo semithombo yamandla ahlanzekile.
Ukubaluleka Kwezilinganiso Ezinembile Zokuminyana
InembileIsilinganiso sokuminyana kwe-LNGibalulekile ekuhwebeni, ekuthumeleni nasekuthutheni i-LNG. Njengoba i-LNG idayiswa ngokusekelwe kokuqukethwe kwamandla ayo, abalwa kusukela kuvolumu, ukuminyana, kanye nevelu yekhalori ephelele, izilinganiso ezinembile zibalulekile ekuthengeni okufanele nokusebenza kahle. Isivinini esikhulu, izilinganiso zokuminyana ezinembile zinenani elikhulu lezentengiselwano, eziqinisekisa ukuthi abahwebi kanyeIzinkampani zokuthumela i-LNGingahlola ngokuzethemba amandla adluliselwe ngesikhathi sokudluliselwa kwesitokisi. Ukungalungi esilinganisweni sokuminyana kungaholela ekulahlekeni kwezimali, ukungalandelwa kwemithetho, noma izinselele zokusebenza, okugqamisa isidingo sezixazululo zokuqapha ezithuthukisiwe.
Izinselelo ku-LNG Density Measurement
Izakhiwo ezihlukile ze-LNG, okuhlanganisa izinga lokushisa eliphansi kakhulu -162°C kanye nokushintsha kokwakheka ngesikhathiEzokuthutha ze-LNG, yethula izinselele ezibalulekile zokulinganisa ukuminyana. Ngesikhathi sokuthunyelwa, i-LNG ithola ukuhwamuka kanye nokushintsha kokuqamba ngenxa yokuhlukahluka kwezinga lokushisa nokucindezela, okuthinta ngokuqondile ukuminyana kwayo. Lezi zinguquko zenza ukuhlolwa kwe-metrological kube inselele, njengoba izindlela zokulinganisa ezivamile zingase zingabali ubunjalo obuguquguqukayo be-LNG. Isibonelo, uhambo olude lwe-ballast lungashintsha kakhulu ukwakheka nokuminyana kwamanani e-LNG, kudingeke izixazululo zokuqapha ezithuthukisiwe, zesikhathi sangempela ezingavumelana nalezi zimo kuyilapho kugcinwa ukunemba.
I-Lonnmeter Inline Density Meters
Ngesipiliyoni esibanzi kuukulinganisa kokuminyana okusemgqeni, I-Lonnmeterinikeza isimo-of-the-artamamitha wokuminyana emgqeniyakhelwe ukuhlangabezana nezidingo ezinzima zeUkuthunyelwa kwe-LNGimboni. Lawa mamitha aklanyelwe ukuletha izilinganiso zejubane eliphezulu, ezinembile, nezithembekile, ngisho nangaphansi kwezimo ze-cryogenic ezidlulele ze-LNG. Yakhiwe ngezinto eziqinile njengensimbi engagqwali, i-hastelloy, i-titanium, noma i-tantalum,Izindawo zokuhlala e- Lonnmeteramamitha aqinisekisa ukuqina nokusebenza ezindaweni ezinokhahlo. Ngokuhlanganisa leziI-LNG density metresemapayipini nge-flange, i-clamp, noma ifakwe ngokuqondile,Izinkampani zokuthumela i-LNGingafinyelela ukuqapha okuqhubekayo kokuminyana, iqinisekise ukuhambisana namazinga emboni kanye nokwenza kahle ukusebenza kahle. Ukuze uthole imininingwane eyengeziwe, vakashelaIkhasi le-Lonnmeter's density metres.
Ukuvimbela Izingozi Ezigingqika
Enye yezinhlelo zokusebenza ezibaluleke kakhulu zokuqapha ukuminyana kuUkuthunyelwa kwe-LNGivimbela izingozi ezigingqika emathangeni okugcina. I-Rolling-over kwenzeka lapho i-LNG efudumele, engaminyene kancane intanta phezu kwe-LNG eminyene, ebandayo, okuholela ekuhwamukeni ngokushesha kanye nokugqashuka kwethangi okungenzeka. Ukuqapha okuqhubekayo kwephrofayili yokuminyana kusetshenziswaI-Lonnmeter's inline density metresingakwazi ukubona izimpawu zakuqala zokuhlukaniswa, okuvumela abaqhubi ukuthi bathathe izinyathelo zokuvimbela. Ngokugcina iphrofayili yokuminyana ezinzile, lawa mamitha adlala indima ebalulekile ekugwemeni ukwehluleka okuyinhlekelele, ukuthuthukisa ukuphepha, nokuvikela izimpahla ezibalulekile ngesikhathiEzokuthutha ze-LNG.
Imibuzo Ejwayelekile Mayelana Nesikali Sokuminyana kwe-LNG
