CNOOC Limited e phatlalatsa hore Mero4 Project e se e qalile tlhahiso e bolokehile ka la 24 Motšeanong nako ea Brasilia.
Sebaka sa Mero se sebakeng sa Santos Basin pele ho letsoai ka boroa-bochabela ho lebopo la Brazil, lik'hilomithara tse ka bang 180 ho tloha Rio de Janeiro, botebong ba metsi pakeng tsa 1,800 le 2,100 metres. Morero oa Mero4 o tla ntlafatsoa ke mokhoa oa setso oa nts'etsopele ea metsi a tebileng pele ho letsoai, FPSO+Subsea. Liliba tse 12 tsa nts'etsopele li reriloe hore li fuoe mosebetsi, ho kenyeletsoa bahlahisi ba oli ba 5, li-injection tse 6 tsa metsi kapa tsa khase, seliba se le seng se fetolehang. E le ho eketsa tlhahiso, liliba li na le theknoloji e bohlale ea ho tlatsa seliba, e nolofalletsang ho fetoha ho tloha hole pakeng tsa lihlahisoa le liliba tsa ente ka sethala. FPSO e sebelisitsoeng Mero4 ke e 'ngoe ea li-FPSO tse kholo ka ho fetisisa lefatšeng, tse neng li kopantsoe Chaena ka December 2024' me li fihlile sebakeng sa oli ka March 2025. FPSO e khona ho hlahisa libarele tsa 180,000 tsa oli e sa hloekang, ho sebetsana le li-cubic metres tse limilione tse 12 tsa khase ea tlhaho ka letsatsi le ho kenya matla a tlhahiso ea metsi a 00,000 250. Tšimong ea Mero ho isa ho libarele tse 770,000 tsa oli e tala ka letsatsi. Ho kenya ts'ebetsong mohopolo oa nts'etsopele ea khabone e tala le e tlase, morero oa Mero4 o boetse o na le lisebelisoa tsa ho sebelisa HISEP (High Pressure Separator), e lumellang karohano e ka tlas'a metsi pakeng tsa oli e ntšitsoeng le khase e amanang le eona le ho khutlisetsa khase ka letamong. HISEP ka nako e le 'ngoe e tla matlafatsa tlhahiso le ho fokotsa tlhahiso.
Khamphani ea rona e ntse e ikemiselitse ho nts'etsapele lisebelisoa tsa karohano tse sebetsang hantle, tse sebetsang hantle le tse baballang chelete e ngata ha e ntse e tsepamisitse maikutlo ho boqapi bo baballang tikoloho. Ka mohlala, ronacyclone desander e sebetsang hantle haholosebelisa lisebelisoa tse tsoetseng pele tsa ceramic (kapa tse bitsoang, tse thibelang khoholeho e phahameng), ho fihlela katleho ea ho tlosa lehlabathe / matla a fihlang ho li-microns tse 0.5 ho 98% bakeng sa kalafo ea khase.
Sena se lumella khase e hlahisoang hore e kenngoe matamong bakeng sa sebaka sa oli se sa khoneng ho kenella ka tlase se sebelisang likhohola tsa khase le ho rarolla bothata ba ho nts'etsopele ha matamo a nang le matla a tlase le ho ntlafatsa haholo ho hlaphoheloa ha oli. Kapa, e ka tšoara metsi a hlahisoang ka ho tlosa likaroloana tsa li-micron tse 2 ka holimo ho 98% bakeng sa ho kenngoa hape ka ho toba matamong, ho fokotsa tšusumetso ea tikoloho ea leoatle ha e ntse e ntlafatsa tlhahiso ea tšimo ea oli ka theknoloji ea likhohola tsa metsi.
Re lumela ka tieo hore ke feela ka ho fana ka lisebelisoa tse phahameng re ka theha menyetla e meholo ea kholo ea khoebo le tsoelo-pele ea litsebi. Boitlamo bona ba boqapi bo tsoelang pele le ntlafatso ea boleng bo tsamaisa ts'ebetso ea rona ea letsatsi le letsatsi, e re fa matla a ho fana ka litharollo tse betere bakeng sa bareki ba rona.
