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

I-QatarEnergy inikele ngesivumelwano sokuklama, ukuthenga, nokwakha (EPC) sezindawo ezisemhlabeni ezikhiqiza igesi yemvelo eligcwalisiwe (LNG) zephrojekthi yayo i-North Field West (NFW) ku-joint venture ehlanganisa i-Technip Energies, i-Consolidated Contractors Company (CCC), kanye ne-Gulf Asia Contractor (GAC). Lesi sivumelwano sibonisa isigaba sokugcina sokwanda okuzokhuphula umthamo wokukhiqiza i-LNG we-Qatar ube ngamathani ayizigidi ezingu-142 ngonyaka (MTPA).

Isivumelwano sihlanganisa ukwakhiwa kwezitimela ezimbili ezinkulu ze-LNG ezinomthamo ohlangene wama-MTPA angu-16, kanye nezindawo ezihambisanayo zokwelapha igesi, ukutholwa kabusha kwama-liquids egosi yemvelo (NGL), kanye nokukhipha i-helium. Kulindeleke ukuthi le phrojekthi ikhiqize cishe amabareli angu-175,000 okulingana namafutha ngosuku we-condensate, i-ethane, kanye ne-liquefied petroleum gas (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 iNorth Field West ilandela izinyathelo zamaphrojekthi iNorth Field East (32 MTPA) kanye neSouth (16 MTPA), igcizelela kakhulu ukusebenza 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 iNorth 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 izotholakala ezitshalweni zamandla elanga zaseQatar.

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

Insimu iNorth Field yaseQatar, etholakala ngaseceleni koMnyango wasenyakatho-mpumalanga wezwe, ingenye yezinsimu zegesi yemvelo ezinkulu emhlabeni, enezinto ezingalulama ezingaphezu kuka-900 trillion cubic feet ezijwayelekile—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 atholakele eNorth Field zilinganiselwa ku-240 trillion cubic feet, okukhuphula izinto zegesi zaseQatar zibe ngaphezu kuka-2,000 trillion cubic feet kanye nezinto ze-condensate zibe ngaphezu kwezigidi ezingama-80 zamabareli.

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. Sizibophezele ekuthuthukiseni imishini yokuhlukanisa nokuhlunga yemboni kawoyela, igesi, kanye ne-petrochemical. Uhlu lwethu lomkhiqizo olusebenza kahle luhlanganisa ama-hydrocyclone okukhipha uwoyela/amanzi, ama-desander ezinhlayiyeni ezincane kakhulu, kanye namayunithi okuhlanganisa okuhlanganisiwe. Sihlinzeka ngezixazululo 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, sihlinzeka ngezixazululo zenqubo ezilungiselelwe, ukuklama komkhiqizo okunembayo, ukugcinwa okuqinile kwezicaciso zobunjiniyela, 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 ukubuyiselwa 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 kwamanzi 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 izinhlayiya eziqinile ezinosayizi abafika ku-2 microns (ngokusebenza okungu-98%) noma ngaphansi.

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

Kufakazelwe emikhakheni emikhulu yomhlaba ephethwe yi-CNOOC, CNPC, Petronas, nabanye kulo lonke elaseNingizimu-mpumalanga ye-Asia, ama-desander e-SAGA afakwa kumapulatifomu e-wellhead nawokukhiqiza. Ahlinzeka ngokususwa okuthembekile kwezinto eziqinile kuwo igesi, uketshezi lokukhiqiza, kanye ne-condensate, futhi abalulekile ekuhlanzweni kwamanzi olwandle, ukuvikelwa komjikelezo wokukhiqiza, kanye nezinhlelo zokujova/ukugcwala kwamanzi.

Ngaphandle kwama-desander, i-SAGA inikeza iqoqo lobuchwepheshe bokuhlukanisa obunconywayo. Umugqa womkhiqizo wethu uhlanganisa izinhlelo zamagobolondo zokukhipha 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.
