Kugeza ubu, kugarura ibikomoka kuri peteroli bidasubiramo biracyari akazi katoroshye cyane, kandi ibikoresho n'ikoranabuhanga byo kugarura, gutunganya no kongera gukoresha gaze ya peteroli ku gikoresho cyo kubika no gucukura amazi (FPSO) gifite umwanya muto n'ibikoresho byinshi mu gutunganya, gutunganya no guturamo ni imbogamizi zikomeye kurushaho.
Mu rwego rwo gusubiza ibi, CNOOC yakomeje kunoza no guhindura ibikoresho bya tekiniki byari bisanzweho mu myaka ya vuba aha, amaherezo bituma umuriro ucanwa kuri FPSO utazongera gucumba umwotsi, kandi izana urwego rw'ikoreshwa n'uburyo bwa tekiniki bwo kugarura umutungo no kongera gukoreshwa ku rwego rushya.
Nk’uko Chen Yimin, umuyobozi mukuru wungirije wa CNOOC Zhanjiang Ishami yabivuze ku ya 5 Ugushyingo, ishami rishinzwe kugarura imyuka ivanze n’amazi (LPG) mu kibuga cy’amavuta cya Wenchang cyo mu ishami rya CNOOC Zhanjiang ryakoze mu mutekano mu gihe cy’amezi atandatu kandi rikora neza, rigera ku ngaruka zari ziteganijwe zo kugerageza umusaruro, aho buri munsi habonekaga metero kibe 110 za gazi ivanze n’amazi na metero kibe 70 za condensate. Nyuma y’umusaruro usanzwe w’umushinga wo kugarura no gusana LPG mu kibuga cy’amavuta cya Wenchang, metero kibe zigera ku 100000 za gazi zifitanye isano na peteroli zishobora kuboneka buri mwaka. Uyu mushinga uzagira uruhare runini mu kurengera ibidukikije byo mu mazi.
Ibigo bya peteroli byo mu mazi bifite amahirwe menshi yo kubungabunga ingufu
Ishami rya CNOOC Zhanjiang rishinzwe kugarura no guhindura LPG ryageze ku ngaruka zari zitezwe zo gukora igerageza, ritagamije gusa kongera ubuzima bw'ubukungu bw'ikigega cya peteroli, ahubwo rinagaragaza ko mu gihe kizaza ibikorwa byo guteza imbere ibigo by'imari n'umutungo, kugarura no kongera gukoresha umutungo bizagenda byongerwa buhoro buhoro ku rwego rumwe cyangwa runini nk'urwo gukora no guteza imbere ingufu.
Chen Yimin yavuze ko muri iki gihe, ibikomoka kuri peteroli byo mu mazi bifite ubushobozi bwo kuzigama ingufu, kuko mu gihe cyo gukoresha peteroli, gazi iherekejwe n'amazi ya peteroli izagaragara hagati y'ibice bya peteroli. Igice cy'ingenzi ni methane, ubusanzwe irimo ingano nini ya ethane na hydrocarbon. Kugarura no gutunganya gazi bifitanye isano bivuga gutandukanya ethane, propane, butane n'ibice biremereye n'umugezi wa gazi, bishobora gukomeza gutunganywa no kugurishwa nk'ibice by'umwimerere cyangwa uruvange rwa gazi karemano (NGL) cyangwa LPG. Kubwibyo, gazi ifitanye isano ni iy'ingufu ziboneka. Ariko, bitewe n'uburyo buciriritse bw'ikoranabuhanga n'uburyo bigoye kugenzura gazi ifitanye isano mu ikoreshwa ry'ibikomoka kuri peteroli, igice kinini cya gazi ifitanye isano kirakurwa cyangwa kigatwikwa.
Yanatanze urugero rugaragara kugira ngo agaragaze ikibazo: ku gikorwa cyo mu majyepfo y'Ubushinwa, FPSO y'ishami rya CNOOC Zhanjiang rikorera mu kibuga cya peteroli cya Wenchang, itara ririmo kwaka umwaka wose kugira ngo rihuze na gaze ijyanye nayo iva mu bibanza bya peteroli byo mu mazi. Nyuma yo kubara, gaze ijyanye nayo n'amazi bitwikwa n'urumuri buri munsi byaba bingana na Ferrari ku giciro cy'icyo gihe. Kubwibyo, ni ngombwa ko ishami rya CNOOC Zhanjiang rikora umushinga wo gusana no gukoresha gaze ijyanye n'amafarashi, kunoza ubushobozi bwo gukora ibibanza bya peteroli no guteza imbere iterambere ry'ubukungu buzigama ingufu.
