I-Deep Sea One, insimu enkulu yegesi yasolwandle yaseChina, idlule umkhiqizo waminyaka yonke kaphethiloli negesi ofana namathani ayizigidi ezingu-4.5 ngo-2025!

NgoJanuwari 2, i-CNOOC yamemezela ukuthi insimu enkulu yegesi yasolwandle yaseChina, i-"Deep Sea No.1," isiqedile ukuthunyelwa kwayo kwezingu-100 uwoyela oluhlaza kusukela yaqala ukusebenza, kanti imikhiqizo yayo yamafutha negesi idlula amathani ayizigidi ezingu-4.5 we-oil equivalent ngo-2025.

Insiza kagesi "Deep Sea No.1" yasolwandle ejulile yi-offshore gas field eyathuthukiswa ngokuzimela yiChina enamanzi ajulile kakhulu okusebenza, izinga lokushisa nelokucindezela eliphezulu kakhulu, izimo eziyinselele kakhulu zokuhlola nokuthuthukisa, kanye nomthamo omkhulu wokukhiqiza igesi yemvelo kuze kube manje. Isebenza ngamanzi ajulile angaphezu kwamamitha angu-1,500, izinga lokushisa elifinyelela ku-138 degrees Celsius. Le nsiza inezinto eziqinisekisiwe zemvelo zegesi yemvelo ezingaphezu kwebhiliyoni ezingu-150 cubic meters futhi iyathuthukiswa ngezigaba ezimbili.

Izinsiza eziyinhloko zephrojekthi yezigaba ezimbili—isiteshi samandla i-"Deep Sea No.1" kanye neqembu lamapulatifomu i-"four-star constellation"—zombili zihlome ngezinto eziyisisekelo zokucubungula uwoyela negesi yasolwandle olujulile, okuvumela ukuhlukaniswa kwendawo nokudluliselwa kwegesi yemvelo uwoyela oluhlaza ngaphandle kolwandle.

Njengamanje, i-"Deep Sea No.1" ikhiqiza amamitha ayizigidi ezingu-15 wegesi yemvelo namathani angaphezu kuka-1,600 kawoyela we-condensate nsuku zonke. Ingxenye kawoyela we-condensate igcinwa ezitsheni zokugcina uwoyela ngaphakathi kwezinsika ezine zepulatifomu. Uma isilinganiso esithile sifinyelelwa, idluliselwa ngezithuthi ezihamba ngomkhumbi.

Ithimba lokusebenza esizeni lihlale liguqula izinsiza zokukhiqiza ze-"Deep Sea No.1," lisebenzisa iminyaka yokuhlangenwe nakho ekuphathweni kokukhiqiza izinkundla zegesi zasolwandle ukuthuthukisa izinqubo zobuchwepheshe futhi lenze kukhulu amandla okukhiqiza enkundla yegesi ejulile. Kuze kube manje, leli thimba lizimisele ukwakha uhlelo oluphelele lobuchwepheshe bokusebenza nokugcinwa kwezinkundla zegesi ezijulile kakhulu, okuvumela ukuthi imisebenzi yokudlulisa uwoyela oluhlaza esiteshini samandla se-"Deep Sea No.1" iqedwe ngaphansi kwamahora angu-8.

Ukukhiqizwa kukagwayi 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/amanzi, ama-desander ezinhlayiya ezincane kakhulu, kanye namayunithi okuhlanganisa. Sinikeza izixazululo eziphelele ezifakwe ku-skid futhi sinikeza nokulungiswa 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 ezilungiselelwe, ukuklama komkhiqizo okunembayo, ukuthobela okuqinile imininingwane yobunjiniyela, kanye nokusekelwa okuqhubekayo kokusebenza.

Yethu ama-cyclone desanders aphumelela kakhulu, ezaziwa ngesilinganiso sazo esihle kakhulu sokuhlukanisa esingu-98%, zithole ukubuyekezwa okuvela kubaholi bamandla aphesheya kwezilwandle. Zakhiwe ngobuchwepheshe obusezingeni eliphezulu be-ceramics ekwazi ukumelana nokuguga, lezi zinhlelo zikwazi ukususa 98% wezinhlayiya ezincane njengama-0.5 microns emifudlaneni yegesi. Leli khono lenza ukuthi igesi ekhiqiziwe ingafakwa kabusha ukuze kusetshenziswe i-miscible flooding emingceleni enomthamo ophansi, isixazululo esibalulekile sokuthuthukisa ukubuyiselwa kukaphethiloli ezindaweni eziyinselele. Kungenjalo, zingakwazi ukwelapha amanzi akhiqiziwe, zisuse 98% wezinhlayiya ezinkudlwana kunama-2 microns ukuze zingafakwa kabusha ngqo, ngaleyo ndlela zithuthukise ukusebenza kahle kokugeleza kwamanzi ngenkathi kuncishiswa umthelela emvelweni.

Umkhiqizo wethu omusha——I-High Efficiency Ultra-Fine Particle Desander iyithuluzi lokuhlukanisa liquid-solid elisebenzisa umgomo ophumelelayo we-centrifugal ukuhlukanisa izinto ezingcolile eziphakanyisiwe—njengama-solids emanzini akhiqiziwe, amanzi olwandle, i-condensate, ama-particles amancane emanzini anobukhulu obuphezulu, kanye nopowder ye-catalyst kuma-reactors—kwezinye izinyibilikisi (amanzi, amagesi, noma inhlanganisela yamagasi-namanzi). Ikhishwa kahle ama-particles aqinile anobukhulu obuphansi ku-2 microns (ngokusebenza okungu-98%) noma amancane.

I-High Efficiency Ultra-Fine Particle Desander ithola ukusebenza kahle kokukhipha isihlabathi, ikwazi ukukhipha ama-particulate aqinile afika ku-2 microns. Le mishini inezici ezincane, ayidingi amandla angaphandle noma izithasiselo zamakhemikhali, futhi inempilo yokusebenza engaba yimizuzu engama-20. Iphinde inikeze amandla okukhishwa kwesihlabathi ku-inthanethi ngaphandle kokudinga ukuvalwa kokukhiqiza.

Iboniswe ezindaweni ezinkulu zomhlaba ezisebenza ngama-CNOOC, CNPC, Petronas, nabanye eNingizimu-mpumalanga ye-Asia, ama-SAGA desanders asetshenziswa ezindaweni zokuphuma nokukhiqiza. Anikeza ukususa okuqinisekisiwe kwezinto eziqinile emoyeni, emanzini, nasekondensate, futhi abalulekile ekuhlanzeni amanzi olwandle, ukuvikela umjikelezo wokukhiqiza, kanye nezinhlelo zokufaka amanzi/ukukhukhula.

Ngaphandle kwama-desanders, i-SAGA inikeza iphakethe lezi technology zokuhlukanisa ezidumile. Umugqa wethu wemikhiqizo uhlanganisa izinhlelo ze-membrane zokukhipha i-CO₂ emoyeni wemvelo, ama-hydrocyclones okukhuhla amanzi, ama-compact flotation units (CFUs) enza kahle kakhulu, ukuhlanzwa kwe-shale gas，Iphakheji yokukhipha amanzi ye-cyclonic enezinhlaka zokwelapha amanzi akhiqiziwe，naku ama-hydrocyclones amaningi, ahlinzeka ngezixazululo eziphelele ezinselelweni ezinzima zemboni.
