CNOOC Limited na-ekwupụta na Mero4 Project amalitela mmepụta n'enweghị nsogbu na Mee 24 oge Brasilia.

Ogige Mero dị na Santos Basin pre-salt southheast offshore Brazil, ihe dị ka kilomita 180 site na Rio de Janeiro, na omimi mmiri dị n'etiti 1,800 na 2,100 mita. Mero4 Project ga-emepe ya site na usoro mmepe mmiri miri emi tupu nnu, FPSO+Subsea. A na-eme atụmatụ ịnye olulu mmiri 12 mmepe, gụnyere ndị na-emepụta mmanụ ise, mmiri 6 ma ọ bụ gas ọzọ injectors, olulu mmiri nwere ike ịgbanwe. Iji mee ka mmepụta ya dịkwuo elu, a na-eji teknụzụ mmecha nke ọma nwere ọgụgụ isi nke ọma, nke na-enyere aka ịgbanwe n'etiti mmepụta na olulu mmiri injection site na ikpo okwu. The FPSO eji na Mero4 bụ otu n'ime ndị kasị ibu FPSOs n'ụwa, nke e integrated na China na December 2024 na rutere oilfield na March 2025. The FPSO bụ ike na-emepụta ruo 180,000 barel nke crude mmanụ, usoro 12 nde cubic mita arụnyere na eke gas kwa ụbọchị na igba 250 cubic ike mmepụta nke ubi nke Mero. Barel mmanụ 770,000 kwa ụbọchị. Iji mejuputa echiche nke akwụkwọ ndụ akwụkwọ ndụ na mmepe carbon dị ala, Mero4 a kwadeberekwa ihe onwunwe iji rụọ ọrụ HISEP (High Pressure Separator), nke na-enye ohere nkewa n'okpuru mmiri n'etiti mmanụ a na-amịpụta na gas jikọtara ya ma tinyeghachi gas n'ime ọdọ mmiri ahụ. HISEP ga-ebuli mmepụta n'otu oge ma belata ikuku.

Ụlọ ọrụ anyị na-agba mbọ na-emepe emepe ngwa ngwa nkewa nke ọma, kọmpat, na ọnụ ahịa dị ọnụ ala ma na-elekwasị anya na mmepụta ihe ọhụrụ na gburugburu ebe obibi. Dịka ọmụmaatụ, anyịcyclone desander na-arụ ọrụ nke ọmajiri ihe na-eguzogide seramiiki dị elu (ma ọ bụ nke a na-akpọ, mgbochi-erosion nke ukwuu) ihe, na-enweta nrụpụta ájá/mkpụrụ siri ike nke ruru 0.5 microns na 98% maka ọgwụgwọ gas.

Nke a na-enye ohere ka a na-agbanye gas na-emepụta n'ime ọdọ mmiri maka ebe nchekwa mmanụ dị ala nke na-eji iju mmiri gas na-adịghị mma ma na-edozi nsogbu nke mmepe nchekwa mmiri dị ala ma na-eme ka mgbake mmanụ dịkwuo elu. Ma ọ bụ, ọ nwere ike ịgwọ mmiri a na-emepụta site na iwepu irighiri ihe nke 2 microns n'elu na 98% maka ịgbanye ya ozugbo n'ime mmiri mmiri, na-ebelata mmetụta gburugburu ebe obibi mmiri ma na-eme ka mmepụta mmanụ na-emepụta mmanụ na nkà na ụzụ mmiri.
