Isamba sokuphuma kukawoyela ekuthuthukisweni kwesibili kwe-Liuhua Oilfield, okuyindawo yokuqala kawoyela ejulile e-China, sekudlule izigidi ezi-2 zamathani. Ama-hydrocyclone okususa uwoyela e-SAGA ayabandakanyeka

Inani eliphelele likawoyela ongahluziwe elikhishwe kuphrojekthi yokuthuthukiswa kwesibili ye-Liuhua Oilfield—insimu kawoyela yokuqala yasemanzini ajulile e-China—selidlule ngokusemthethweni amathani ayizigidi ezimbili. Lokhu kubonisa ukuthi imodeli yokuthuthukiswa kwesibili yase-China yamafildi kawoyela asemanzini ajulile asevuthiwe imelane nokuhlolwa kokukhiqiza okuqhubekayo ekusebenzeni kwangempela, futhi inikeza isibonelo esingasetshenziswa sokuthuthukisa izinga nokusebenza kahle kanye nokukhipha amandla okukhiqiza emafildini afanayo asevuthiwe.

Njengoba umkhumbi wamathangi i-“Beihai Kaituo” usuka futhi uhamba, ugcwele amathani angama-42,000 kawoyela wasemanzini ajulile ovela ku-“Haikui No. 1,” isitshalo sokuqala sase-Asia sokucubungula uwoyela negesi sasolwandle esiyisilinda, esisisebenze iminyaka emibili kuphela, sasuka endaweni yesikhulumi i-“Haiji No. 2” saya ezweni. Lokhu futhi kwenza inani eliphelele likawoyela ongahluziwe elithunyelwe ngaphandle kuphrojekthi yokuthuthukiswa kwesibili ye-Liuhua Oilfield lafinyelela kumathani ayizigidi ezimbili namashumi amabili ezinkulungwane.

Iphrojekthi yokuthuthukiswa kwesibili kwe-Liuhua Oilfield itholakala emanzini e-Pearl River Mouth Basin, ngokujula kwamanzi okusebenza okulinganiselwa kumamitha angu-305. Incike kakhulu ekusebenzeni ngokubambisana okubandakanya i-"Haiji No. 2," okuyipulatifomu yokuqala yasolwandle ejulile e-Asia; i-"Haikui No. 1," okuyisitshalo sokuqala sase-Asia sokucubungula uwoyela negesi sasolwandle esiyisilinda; kanye nohlelo lokukhiqiza olungaphansi kolwandle. Sekusetshenziswe imithombo yokukhiqiza engu-32, kanti umkhiqizo omkhulu kakhulu wansuku zonke wamafutha aluhlaza ufinyelela kumathani angu-3,900.

Ngokusho kukaShu Zhengyong, umqondisi weplatifomu ye-“Haiji No. 2” yaseLiuhua Oilfield ngaphansi kweChina National Offshore Oil Corporation (CNOOC), ngemuva kokucutshungulwa kokuqala eplatifomu ye-“Haiji No. 2”, uwoyela ongahluziwe okhishwayo uthunyelwa ngezintambo ezingaphansi kolwandle eziya e-“Haikui No. 1” ukuze ucutshungulwe futhi ugcinwe, ekugcineni uthunyelwe ngaphandle. Yonke inqubo yokusebenza ifinyelele ukulawulwa okuzimele kochunge lwamanje.

Njengensimu kawoyela yokuqala yasemanzini ajulile eChina, iLiuhua Oilfield, ngemuva kweminyaka eyishumi yocwaningo lwezobuchwepheshe, ithimba layo locwaningo lathuthukisa ngempumelelo ukubuyiselwa kukawoyela kanye nokusebenza kahle kokukhiqiza, landisa isikhathi sokuphila kwensimu kawoyela ngeminyaka engama-30.

UFan Huaiyong, umphathi wokukhiqiza weCNOOC’s Liuhua Operating Company, uthe kuze kube manje, insimu kawoyela isikhiqize ngokuhlanganyela amathani ayizigidi ezingama-40 kawoyela ongahluziwe, futhi umkhiqizo wayo wansuku zonke ufinyelele izinga eliphezulu kusukela yaqala ukukhiqiza eminyakeni engama-22 edlule.

Ukukhishwa ngempumelelo kwamandla okukhiqiza kuqinisekisa ngokugcwele ukwethembeka kwemodeli entsha yentuthuko kanye nohlelo lwezobuchwepheshe lokuzinzisa uwoyela nokulawula amanzi kuphrojekthi yentuthuko yesibili yaseLiuhua Oilfield. Futhi kuhlola isisombululo esingenzeka "seChinese" sokuthuthukiswa kwamasimu kawoyela ajulile aseChina esikhathini esizayo ngezinga elikhulu nangendlela engabizi kakhulu.

Emkhakheni wokuhlola nokuthuthukiswa kukawoyela negesi emanzini ajulile, iChina ithole ukweqa okungokomlando kusuka kumamitha angu-300 kuya kumamitha angu-1,500 amanzi ajulile kakhulu, yaba ngelinye lamazwe ambalwa emhlabeni anamandla okwenza ngokuzimela ukuhlola nokuthuthukiswa kukawoyela negesi emanzini ajulile.

Eminyakeni yamuva nje, i-CNOOC isungule ngokuzimela uchungechunge lwamathuluzi abukhali asemanzini ajulile afana ne-“Xuanji,” “Haijing,” kanye ne-“Haimai,” yanqoba ngokulandelana izinselele zobuchwepheshe ezisezingeni lomhlaba ezindaweni ezijwayelekile zamanzi ajulile, amanzi ajulile kakhulu, kanye namazinga okushisa aphezulu kanye nengcindezi ephezulu emanzini ajulile, futhi yakha uhlelo lobuchwepheshe bamanzi ajulile olunamalungelo obunikazi azimele.

Kulo msebenzi obalulekile, i-hydrocyclone eyaklanywa futhi yakhiqizwa yi-SAGA isetshenziswe ngempumelelo kulo msebenzi obalulekile, isebenzisa ubuchwepheshe bayo bokuhlukanisa obuthuthukile. Ukusebenza kwayo okukhethekile nokuthembeka kwayo kunikeza ukusekelwa okuqinile ekusebenzeni kahle komsebenzi.

Ama-hydrocyclone ayimishini evamile yokuhlukanisa uwoyela namanzi emikhakheni kawoyela. Ngokukhiqiza amandla e-centrifugal anamandla ngokwehla kwengcindezi, le mishini idala umoya ovunguzayo onesivinini esiphezulu ngaphakathi kweshubhu le-cyclone. Ngenxa yomehluko wokuminyana koketshezi, amaconsi kawoyela angasindi acindezelwa abheke phakathi nendawo, kuyilapho izingxenye ezisindayo zisunduzwa zibheke odongeni lwangaphandle.

I-hydrocyclone isebenzisa ukwakhiwa kwesitsha esinengcindezi futhi ihlanganisa amashubhu e-hydrocyclone aklanywe ngokukhethekile (i-Modeli ye-MF-20). Isebenzisa amandla e-centrifugal akhiqizwa i-vortex ejikelezayo ukuhlukanisa amaconsi kawoyela amahhala emanzini njengamanzi akhiqizwayo. Lo mkhiqizo unesimo esincane, isakhiwo esilula, nokusebenza okulula, okwenza kufanele izimo ezahlukene zokusebenza. Ingasetshenziswa njengeyunithi ezimele noma ihlanganiswe nezinye izinto zokusebenza (njengamayunithi e-flotation, izihlukanisi ezi-coalescing, amathangi e-degassing, nezihlukanisi eziqinile ezi-ultra-fine) ukwakha uhlelo oluphelele lokwelapha nokujova kabusha amanzi akhiqizwayo. Izinzuzo eziyinhloko zifaka umthamo ophezulu wokugeleza ngeyunithi ngayinye yevolumu ngendawo encane, ukusebenza kahle okuphezulu kokuhlukanisa (kufika ku-80%–98%), ukuguquguquka kokusebenza ngama-turndown ratios e-1:100 noma ngaphezulu, izindleko eziphansi zokusebenza, nempilo ende yesevisi.
