Kwangirika kwimbere kwatumye ADNOC igira igihombo cyoguhagarika umuyoboro wumurima munini wamavuta yo ku nkombe.Icyifuzo cyo gukuraho iki kibazo no gukenera gusobanura neza na gahunda nyayo yo gucunga neza ubunyangamugayo bwatumye habaho igeragezwa ryikigereranyo rya tekinoroji ya polyethylene (HDPE) ikora ibiciro bya tekinoroji ya karubone yerekana ko gahunda ya HDPE yerekana ko ikorwa neza ryakozwe na pome ya karubone. uburyo bwo kugabanya ruswa yimbere mumiyoboro ya peteroli mugutandukanya imiyoboro yicyuma mumazi yangirika.Ikoranabuhanga rirahenze mugucunga ruswa imbere mumiyoboro ya peteroli.
Muri ADNOC, Flowlines yagenewe kumara imyaka irenga 20.Ibi nibyingenzi mugukomeza ubucuruzi no kugabanya amafaranga yo gukora.Nyamara, gukomeza iyi mirongo ikozwe mubyuma bya karubone biba ingorabahizi kuko biterwa no kwangirika kwimbere biturutse kumazi yangirika, bagiteri, nibihe bidahagarara biterwa numuvuduko muke.
ADNOC ikora imiyoboro ku gitutu cya 30 kugeza kuri 50, ubushyuhe bugera kuri 69 ° C no kugabanuka kwamazi kurenga 70%, kandi yagize ibibazo byinshi byo gutakaza ibicuruzwa bitewe no kwangirika kwimbere mu miyoboro mu mirima minini yo ku nkombe.Ibyanditswe byerekana ko umutungo watoranijwe wonyine ufite imiyoboro ya peteroli irenga 91 (kilometero 302) hamwe n’imiyoboro irenga 45 yo gushyiramo ingufu za ruswa. 2), kuba CO2 (> 3%) na H2S (> 3%), igipimo cya gaze / peteroli irenga 481 scf / bbl, ubushyuhe bwumurongo burenze 55 ° C, umuvuduko wumurongo uri hejuru ya 525 psi. gihe.Ibi bitera ikibazo gikomeye kuko biganisha kumeneka no guhagarika bigira ingaruka mbi kumusaruro.
Gutakaza ubukana hamwe no gukenera ubunini hamwe na gahunda nyayo yo gucunga neza umurongo wa gahunda yatunganijwe byatumye hashyirwa mu bikorwa ikizamini cya tekinoroji ya HDPE itondekanye kandi idafite flangless muri kilometero 3.0 ya Gahunda 80 API 5L Gr.B 6. Imirongo 6. Gukemura iki kibazo. Ibigeragezo byakorewe bwa mbere byakoreshejwe kuri kilometero 3.527 z'imiyoboro ya karubone ku mutungo watoranijwe, hanyuma hakurikiraho gupimwa cyane muri kilometero 4.0 z'imiyoboro.
Inama y’ubutwererane y’ikigobe (GCC) yingenzi muri peteroli y’Abarabu yari yarashyizeho imirongo ya HDPE guhera mu mwaka wa 2012 mu miyoboro ya peteroli ya peteroli no gukoresha amazi. Ikigo cy’amavuta ya GCC gikorana na Shell kimaze imyaka isaga 20 gikoresha imirongo ya HDPE mu gukoresha amazi n’amavuta, kandi ikoranabuhanga rirakuze bihagije kugira ngo bikemure ruswa y’imbere mu miyoboro ya peteroli.
Umushinga wa ADNOC watangijwe mu gihembwe cya kabiri cy'umwaka wa 2011 ushyirwaho mu gihembwe cya kabiri cy'umwaka wa 2012. Igenzura ryatangiye muri Mata 2012 rikarangira mu gihembwe cya gatatu cya 2017. Ibizamini by'ibizamini byoherezwa mu kigo cya Borouge Innovation Centre (BIC) kugira ngo bisuzumwe kandi bisesengurwe.
Impapuro SPE-192862 isobanura ingamba zigira uruhare mu gutsinda kw'ibigeragezo byo mu murima. Icyibandwaho ni igenamigambi, gushyira imiyoboro, no gusuzuma imikorere ya HDPE kugira ngo bunguke ubumenyi bukenewe kugira ngo hamenyekane ingamba zo gucunga neza ubunyangamugayo bwo gushyira mu bikorwa imirima ya HDPE mu miyoboro ya peteroli. Ubu buhanga bukoreshwa mu miyoboro ya peteroli ikoreshwa mu miyoboro ya peteroli idashobora gukoreshwa. ures kubera kwangirika kwangirika kwimbere.
Urupapuro rwuzuye rusobanura ibipimo ngenderwaho bya gasketi ya HDPE;guhitamo ibikoresho bya gasike, gutegura, no kuyikurikirana;kumeneka ikirere no gupima hydrostatike;buri mwaka guhumeka gazi no gukurikirana;gutangiza umurongo;n'ibisubizo birambuye nyuma yikizamini. Imbonerahamwe yubuzima bwa Streamline Ubuzima Bwerekana Isesengura ryerekana ikiguzi-cyiza cyicyuma cya karubone hamwe na HDPE kumurongo wubundi buryo bwo kugabanya ruswa, harimo gutera inshinge ningurube, imiyoboro idafite ibyuma, hamwe nicyuma cya karubone cyambaye ubusa. Icyemezo cyo gukora ikizamini cya kabiri cyongerewe imbaraga nyuma yikizamini cya mbere nacyo cyasobanuwe neza. Gukoresha intoki ahantu ha flange ntibisaba gusa gukurikirana buri gihe, byongera amafaranga yo gukora, ariko kandi bikavamo no kohereza imyuka ihumanya ikirere mu kirere.Mu kigeragezo cya kabiri, flanges yasimbujwe imiyoboro ihuza imashini isudira, idafite flangless hamwe na sisitemu yo kuzuza byikora, hamwe na lisansi yashyizwe hamwe na enterineti irangirira kuri sitasiyo ya kure yangirika.
Ikigeragezo cyimyaka 5 cyemeza ko gukoresha imirongo ya HDPE mu miyoboro yicyuma cya karubone bishobora kugabanya kwangirika kwimbere mu miyoboro ya peteroli mu gutandukanya imiyoboro yicyuma n’amazi yangirika.
Ongeraho agaciro utanga serivise yumurongo udahagarara, ukuraho ingurube zimbere kugirango ukureho ububiko na bagiteri, uzigame amafaranga ukuraho ibikenerwa byimiti igabanya ubukana na biocide, no kugabanya akazi
Icyari kigamijwe kwipimisha kwari ukugabanya kwangirika kwimbere yumuyoboro no gukumira igihombo cyibanze.
Imirongo ya HDPE ifatanye hamwe na welded flangeless ifatanije ikoreshwa ifatanije na sisitemu yo kongera gutera inshinge nkiterambere ryiza hashingiwe kumasomo twakuye muburyo bwoherejwe bwa mbere kumurongo wa HDPE usanzwe ufite clips kuri terefone.
Ukurikije ibipimo byatsinzwe no gutsindwa byashyizweho kuri pilote, nta makuru yigeze atangazwa mu muyoboro kuva yashyirwaho.Ikindi kizamini nisesengura ryakozwe na BIC byagaragaje ko ibiro 3-5% byagabanutse ku murongo wakoreshejwe, ibyo bikaba bidatera iyangirika ry’imiti nyuma y’imyaka 5 ikoreshwa. Haragaragaye ibishushanyo bimwe na bimwe bitigeze bigera no mu cyuho. nko gusimbuza flanges hamwe nu muhuza no gukomeza umurongo no gukoresha valve ya cheque kumurongo kugirango utsinde gaze ya gaze yumurongo) nigisubizo cyizewe.
Iri koranabuhanga rikuraho iterabwoba ry’imbere kandi ritanga amafaranga menshi yo gukoresha mu gihe cyo kuvura imiti, kuko nta miti ikenewe.
Iyemezwa ryikoranabuhanga ryagize ingaruka nziza kumicungire yubusugire bwabakozi, bitanga ubundi buryo bwo gucunga neza ruswa imbere, kugabanya ibiciro muri rusange no kunoza imikorere ya HSE.
Ikoreshwa rya tekinoroji ya HDPE irasabwa kubutaka bwa peteroli na gaze bihari aho imiyoboro itemba hamwe no guhagarika umurongo wo gutera amazi.
Iyi porogaramu izagabanya umubare wananiwe gutemba uterwa no kuva imbere, kwagura ubuzima, no kongera umusaruro.
Iterambere rishya ryuzuye rirashobora gukoresha tekinoroji muburyo bwo gucunga ruswa no kuzigama amafaranga kuri gahunda yo gukurikirana.
Iyi ngingo yanditswe n’umwanditsi mukuru wa tekiniki JPT, Judy Feder kandi ikubiyemo ibintu byingenzi byagaragaye mu mpapuro za SPE 192862, "Ikigereranyo cyo Kugerageza Ikigereranyo Cy’ibisubizo bya Flangeless Grooved HDPE Liner Porogaramu mu gice cya super Gigantic Field for Oil Flowline Management Corrosion Internation" cyanditswe na Abby Kalio Amabipi, SPE, Marwan Hamad Salem, Siva Prasada ADN GH;Mohamed Ali Awadh, Borouge PTE;Nicholas Herbig, Jeff Schell na Ted Compton bo muri United Special Services Services muri 2018 2018 i Abu Dhabi, ku ya 12-15 Ugushyingo Witegure imurikagurisha mpuzamahanga rya peteroli rya Abu Dhabi.Iyi mpapuro ntabwo yasuzumwe n’urungano.
Ikinyamakuru cy’ikoranabuhanga rya peteroli nicyo kinyamakuru cyamamaye cy’umuryango w’abashoramari ba peteroli, gitanga ibisobanuro byemewe n’ibiranga iterambere mu ikoranabuhanga mu bushakashatsi n’umusaruro, ibibazo by’inganda za peteroli na gaze, namakuru yerekeye SPE n’abanyamuryango bayo.
