Umthamo we-LNG oboshiwe we-CNOOC we-bunkering usukhuphuke wadlula amakhubhu amamitha ayizigidi eziyisikhombisa neshumi

Umkhumbi i-Haiyang Shiyou 301 uqedele umsebenzi wokufaka i-LNG (i-liquefied natural gas) eboshiwe emkhunjini ohamba emazweni omhlaba e-Thekwini lase-Yantian e-Shenzhen. Ngalo msebenzi, inani eliphelele le-LNG eboshiwe elenziwe yi-CNOOC selidlule ama-cubic metres angu-800,000.

Kuze kube manje, imikhumbi emibili ye-CNOOC yokuthutha nokufaka i-LNG isiqedele imisebenzi engu-143 yokufaka. Phakathi kwabo, i-Haiyang Shiyou 301 yenze imisebenzi engu-69 enenani eliphelele lama-cubic metres angu-421,000, kuyilapho i-Haiyang Shiyou 302 yenze imisebenzi engu-74 enenani eliphelele lama-cubic metres angu-380,000. Ngokusebenzisa ukuhlelwa kwazo okuhlukile, le mikhumbi emibili isungule inethiwekhi ephelele yesevisi ehlanganisa umfula nolwandle.

Njengomqhubi oyinhloko we-bonded LNG bunkering yasekhaya, ibhizinisi le-CNOOC linamathuba amaningi ahlukahlukene. Mayelana nokwakheka kwemikhumbi, imikhumbi iyasebenzisana ngamandla ayo: I-Haiyang Shiyou 301, umkhumbi omkhulu kunayo yonke emhlabeni wokuthutha nokufaka i-LNG, unethangi elikhulu elingamakhubhu amamitha ayi-30,000, elisekela ukufakwa kwe-LNG okuqhubekayo emikhunjini eminingi futhi lifaneleka kahle ukuhlangabezana nezidingo zokuphehla uphethiloli zemikhumbi emikhulu yamazwe ngamazwe emachwebeni asogwini. I-Haiyang Shiyou 302, ngomklamo wayo okhethekile one-shallow draft, collapsible mast, kanye ne-ice class navigation capability, ingafinyelela eNingbo nasemachwebeni asemfuleni i-Yangtze, ngaleyo ndlela igcwalisa igebe le-bonded bunkering emifuleni. Ukuhlelwa okuhlanganisa umfula nolwandle kufeza ukumbozwa okugcwele kwezimo zokusebenza emanzini asogwini nasemifuleni.

Okwamanje, izinsizakalo ze-LNG bunkering ze-CNOOC zifaka izikhumulo eziningi ezisemqoka kufaka phakathi iShenzhen, iNingbo, iGuangzhou, iHong Kong, kanye neXiamen. Le nkampani ikwazi ngasikhathi sinye ukwenza imisebenzi ye-bunkering eceleni kwejetty nasezindaweni zokuhlala, ivumela izixazululo zokuhlinzeka eziguquguqukayo ezihambisana nezindlela zezimoto nezinhlelo zokubeka, ngaleyo ndlela kuthuthukiswe kahle ukusebenza kokuphenduka kwemikhumbi yamazwe omhlaba.

Ukukhishwa kukawoyela kanye nogesi wemvelo akukwazi ukufezeka ngaphandle kwemishini yokuhlukanisa.

I-SAGA Offshore Engineering Co., Ltd. yaseShanghai, eyasungwa eShanghai ngo-2016, iyinkampani yesimanje yezobuchwepheshe ehlanganisa ucwaningo nokuthuthukiswa, ukuklama, ukukhiqiza, kanye nezinsizakalo. Sizinikele ekuthuthukiseni imishini yokuhlukanisa nokuhlunga embonini kawoyela, igesi, kanye nepetrokhemikhali. Iphothifoliyo yethu yemikhiqizo esebenza kahle kakhulu ihlanganisa ama-hydrocyclones okukhipha uwoyela/amanzi, ama-desander ezinhlayiyana ezingama-micron, kanye namayunithi e-compact flotation. Sihlinzeka ngezixazululo eziphelele ezigxilile futhi sinikeza nezinsizakalo zokulungisa kabusha imishini yangaphandle kanye nezinsizakalo zangemva kokuthengisa. Siphethe amalungelo obunikazi amaningi futhi sisebenza ngaphansi kohlelo lokuphatha olugunyazwe yi-DNV-GL ISO-9001, ISO-14001, kanye ne-ISO-45001, sihlinzeka ngezixazululo ezinohlelo oluthuthukisiwe, umklamo oqondile womkhiqizo, ukuhambisana ngokuqinile nezimfuneko zobunjiniyela, kanye nokusekelwa okuqhubekayo kokusebenza.

Ours ama-cyclone desanders aphezulu kakhulu, aziwa ngezinga elihle lokuhlukanisa elingu-98%, zithole ukuqashelwa kubaholi bamandla emhlabeni jikelele. Zakhiwe ngezinto ezithuthukisiwe ezingama-ceramics ezingagugi, lezi zingxenye zikhipha ama-particle angu-98% acishe abe ngu-0.5 microns emgqeni wegesi. Leli khono linika amandla ukufakwa kabusha kwegesi ekhiqiziwe ukuze kuhlanjululwe nge-miscible flooding emithonjeni ene-low-permeability, okuyisixazululo esibalulekile sokuthuthukisa ukutholwa kukawoyela ezindaweni eziyinselele. Ngokunye, zingahlanza amanzi akhiqiziwe, zisuse ama-particle angu-98% amakhulu kuno-2 microns ukuze afakwe kabusha ngqo, ngaleyo ndlela kuthuthukiswe ukusebenza kwe-water-flood kuncishiswe umthelela emvelweni.

Umkhiqizo wethu omusha—I-High Efficiency Ultra-Fine Particle Desander iyithuluzi lokuhlukanisa uketshezi nokuqinile elisebenzisa umgomo ophumelelayo we-centrifugal ukuze kuhlukaniswe ukungcola okumisiwe—njengezinto eziqinile emanzini akhiqiziwe, emanzini olwandle, ku-condensate, ezinhlayiyeni ezincane oketshezini olunamandla aphezulu, nempuphu ye-catalyst kuma-reactor—ezintweni eziwuketshezi (uketshezi, amagesi, noma izingxube zegesi noketshezi). Isusa ngempumelelo izinhlayiya eziqinile ezinobukhulu obufika kuma-micron angu-2 (ngokusebenza kahle okungu-98%) noma ngaphansi.

I-High Efficiency Ultra-Fine Particle Desander iletha ukusebenza okuphezulu kokususa isihlabathi, ikwazi ukususa izinhlayiya eziqinile ezifinyelela ku-2 microns. Umshini unendawo encane, awudingi amandla angaphandle noma izithasiselo zamakhemikhali, futhi unempilo yokusebenza eminyakeni engaba ngu-20. Unikeza ikhono lokukhipha isihlabathi ngenkathi usebenza ngaphandle kwesidingo sokumisa ukukhiqiza.

Kufakazelwe emikhakheni emikhulu yomhlaba wonke eqhutshwa yi-CNOOC, CNPC, Petronas, nabanye kulo lonke elaseNingizimu-mpumalanga ye-Asia, ama-desander e-SAGA asetshenziswa ezindaweni zomthombo kanye nezinkundla zokukhiqiza. Ahlinzeka ngokususwa okuthembekile kwezinto eziqinile kugesi, uketshezi lomthombo, kanye ne-condensate, futhi abalulekile ekuhlanzweni kwamanzi olwandle, ukuvikelwa komfula wokukhiqiza, kanye nezinhlelo zokujova amanzi/ukugcwaliswa kwamanzi.

Ngaphandle kwama-desander, i-SAGA inikeza iphothifoliyo yobuchwepheshe bokuhlukanisa obuhlonishwayo. Umugqa wethu womkhiqizo uhlanganisa izinhlelo ze-membrane zokususa i-CO₂ kugesi wemvelo, ama-hydrocyclone okukhipha uwoyela, ama-unithi aphezulu wokuhlanza amanzi (CFUs), Ukukhishwa kwesihlabathi kugesi we-shale, Iphakethe lokukhipha amanzi nge-cyclonic elihlanganiswe nokwelashwa kwamanzi akhiqiziwe, kanye nama-hydrocyclone anamakamelo amaningi, okuhlinzeka ngezixazululo eziphelele ezinseleleni ezinzima zemboni.
