I-QatarEnergy Inikeza Inkontileka Ye-LNG Yasenyakatho Ye-North Field West Ku-Joint Venture Eholwa Yi-Technip Energies

I-QatarEnergy inikele isivumelwano sokuklama, ukuthenga, nokwakha (EPC) sezindawo ezisemhlabeni ezinegazi lemvelo eligcwalisiwe (LNG) zephrojekthi yayo iNorth Field West (NFW) kunkampani eyenziwe ngokubambisana ehlanganisa iTechnip Energies, iConsolidated Contractors Company (CCC), kanye neGulf Asia Contractor (GAC). Lesi sivumelwano sibonisa isigaba sokugcina sokunwetshwa esizokhuphula umthamo wokukhiqiza i-LNG weQatar ube ngamathani ayizigidi ezingu-142 ngonyaka (MTPA).

Isivumelwano sihlanganisa ukwakhiwa kwezitimela ezimbili ezinkulu ze-LNG ezinomthamo ohlangene wamathani ayizigidi ezingu-16 ngonyaka (MTPA), kanye nezindawo ezihambisanayo zokwelapha igesi, ukuthola kabusha okunguketshezi kwegesi lemvelo (NGL), kanye nokukhipha i-helium. Iphrojekthi kulindeleke ukuthi iphinde ikhiqize cishe amabhalela angu-175,000 okulingana namafutha ngosuku we-condensate, i-ethane, kanye negesi kaphethiloli eligcwalisiwe (LPG).

"Le nkontileka imele ukwengeza okubalulekile kuphrojekthi enkulu kunazo zonke emhlabeni yokwandisa i-LNG futhi iqinisekisa ukuzibophezela kweQatar ukuhlangabezana nesidingo esikhulayo se-LNG emhlabeni wonke," kusho uSaad Sherida Al-Kaabi, uNgqongqoshe wezwe wezindaba zamandla eQatar, uMongameli, kanye noCEO weQatarEnergy.

U-Al-Kaabi wengeze wathi, "Iphrojekthi yeNorth Field West ilandela izinyathelo zamaphrojekthi eNorth Field East (32 MTPA) kanye neSouth (16 MTPA), ibeka isisindo esikhulu ekusebenzeni kwezemvelo. Izici eziyinhloko zihlanganisa amandla okubamba nokugcina ikhabhoni (CCS) angu-1.1 MTPA, okusisondeza ekufinyeleleni umgomo wethu wokubamba nokugcina ngaphezu kuka-11 MTPA we-CO2 ngo-2035."

Iphrojekthi yeNorth Field West izophinde ifake izinsiza zokubuyisa igesi ye-jetty boil-off, okulindeleke ukuthi ibuyise okulingana no-0.42 MTPA we-CO2. Ngaphezu kwalokho, ingxenye enkulu yezidingo zayo zamandla izotholwa ezitshalweni zamandla elanga zaseQatar.

I-LNG yokuqala esivela kuphrojekthi kulindeleke ukuthi itholakale ekupheleni kuka-2031.

Insimu iNorth Field yaseQatar, etholakala ngasechwebeni elisenyakatho-mpumalanga kwezwe, ingenye yezinsimu ezinkulu zegesi yemvelo emhlabeni, enezinto ezingalulama ezingaphezu kuka-900 trillion cubic feet—ezakha cishe u-10% wezinto ezaziwayo emhlabeni. Le nsimu ihlanganisa indawo engaphezu kwamakhilomitha ayi-6,000 ayisikwele.

NgoFebhuwari 2024, iQatarEnergy yamemezela ukuthi izoqhubeka nokwandisa iNorth Field West ukuze yandise umthamo we-LNG kazwelonke ube yi-142 MTPA ngaphambi kokuphela kweshumi leminyaka. Izilinganiso zamagesi engeziwe ezitholakale eNorth Field zilinganiselwa ku-240 trillion cubic feet, okwenza izinto zegesi zaseQatar zibe ngaphezu kuka-2,000 trillion cubic feet kanye nezinto ze-condensate ezingaphezu kwebhiliyoni ezingu-80.

Ukukhiqizwa kukaphethiloli negesi yemvelo akunakwenzeka ngaphandle kwemishini yokuhlukanisa.

I-Shanghai SAGA Offshore Engineering Co., Ltd., eyasungulwa e-Shanghai ngo-2016, iyibhizinisi lobuchwepheshe lesimanje elihlanganisa i-R&D, ukuklama, ukukhiqiza, kanye nenkonzo. Sizinikele ekuthuthukiseni imishini yokuhlukanisa nokuhlunga yemboni kawoyela, igesi, kanye ne-petrochemical. Uhlu lwethu lomkhiqizo osebenza kahle kakhulu luhlanganisa ama-hydrocyclone okukhipha uwoyela/okomisa amanzi, ama-desander ezinhlayiya ezincane kakhulu, kanye namayunithi okuhlanganisa. Sinikeza izixazululo eziphelele ezifakwe ku-skid futhi sinikeza nokulungiswa kabusha kwemishini yenkampani yangaphandle kanye nezinsizakalo zangemuva kokuthengisa. Sibambe amapentente amaningi angobunikazi futhi sisebenza ngaphansi kwesistimu yokuphatha eqinisekiswe yi-DNV-GL ISO-9001, ISO-14001, kanye ne-ISO-45001, siletha izixazululo zenqubo ezithuthukisiwe, ukuklama komkhiqizo okunembayo, ukuthobela ngokuqinile imininingwane yobunjiniyela, kanye nokwesekwa okuqhubekayo kokusebenza.

Ama-ama-desander e-cyclone asebenza kakhulu, ezaziwa ngesilinganiso sazo esihle kakhulu sokuhlukanisa esingu-98%, zithole ukubuyekezwa okuvela kubaholi bamandla aphesheya kwezilwandle. Zakhiwe ngobuchwepheshe obusezingeni eliphezulu be-ceramics okumelana nokuguga, lezi zinhlelo zikwazi ukususa 98% wezinhlayiya ezincane njengama-0.5 microns emifudlaneni yegesi. Leli khono lenza ukuthi igesi ekhiqiziwe ingene kabusha ukuze isetshenziswe ekuhlanjululweni okuxubile kumachibi anomhlaba ongafinyeleleki kalula, isixazululo esibalulekile sokuthuthukisa ukubuyiswa kukaphethiloli ezindaweni eziyinselele. Kungenjalo, zingakwazi ukwelapha amanzi akhiqiziwe, zisuse 98% wezinhlayiya ezinkulu kune-2 microns ukuze zingene kabusha ngqo, ngaleyo ndlela zithuthukise ukusebenza kahle kokuhlanjululwa ngamanzi ngenkathi kuncishiswa umthelela emvelweni.

Umkhiqizo wethu omusha—I-Desander Yamagundane Amancane Kakhulu Esebenza Kakhulu iyidivayisi yokuhlukanisa uketshezi-okuqinile esebenzisa isimiso esisebenza kahle se-centrifugal ukuhlukanisa izinto ezingcolile ezintantayo—njengezinto eziqinile emanzini akhiqiziwe, emanzini olwandle, ku-condensate, amagundane amancane eketsheni elinamandla aphezulu, kanye nomgqomo wokukhipha ukhwehlela kuma-reactor—kusuka eketsheni (uketshezi, amagesi, noma izinhlanganisela zegesi-uketshezi). Iyakhipha ngempumelelo amagundane aqinile anobukhulu obufika ku-2 microns (ngokusebenza okungu-98%) noma amancane.

I-Desander Yamagundane Amancane Kakhulu Esebenza Kakhuluihambisa ukusebenza kahle kakhulu ekususeni isihlabathi, ikwazi ukususa izinhlayiya eziqinile ezifika ku-2 microns. Le mishini inesakhiwo esincane, ayidingi amandla angaphandle noma izithako zamakhemikhali, futhi inomjikelezo wokuphila cishe iminyaka engu-20. Inikeza amandla okukhipha isihlabathi ku-inthanethi ngaphandle kwesidingo sokuyeka ukukhiqiza.

Kufakazelwe emikhakheni emikhulu yomhlaba ephethwe yi-CNOOC, CNPC, Petronas, nabanye kulo lonke elaseNingizimu-mpumalanga ye-Asia, ama-SAGA desanders afakwa ezindaweni zokubeka imithombo yokukhiqiza kanye nezinkundla zokukhiqiza. Ahlinzeka ngokususwa okuthembekile kwezinto eziqinile kuwo igesi, uketshezi lokukhiqiza, kanye ne-condensate, futhi abalulekile ekuhlanzweni kwamanzi olwandle, ukuvikelwa komjikelezo wokukhiqiza, kanye nezinhlelo zokujova/ukugcwalisa amanzi.

Ngaphezu kwama-desanders, i-SAGA ihlinzeka ngohlu lobuchwepheshe bokuhlukanisa obunconywayo. Umugqa womkhiqizo wethu uhlanganisa izinhlelo zamamembrane zokususa i-CO₂ egazini yemvelo, ama-hydrocyclone okukhipha uwoyela, ama-flotation units (CFUs) amancane asebenza kakhulu, ukukhipha isihlabathi ku-shale gas, Iphakethe lokukhipha amanzi nge-cyclonic elokwelapha amanzi akhiqiziwe, kanye ama-hydrocyclone anezimfihlo eziningi, ahlinzeka ngezixazululo eziphelele izinseleleni ezinzima kakhulu zemboni.
