Kuora kwemukati kwakakonzera kuti ADNOC irasikirwe nekurasikirwa kwepombi yenzvimbo huru yemafuta ekumahombekombe. Chishuvo chekubvisa dambudziko iri uye kukosha kwekutsanangudza uye neramangwana rakajeka rekugadzirisa kutendeseka manejimendi chirongwa chatungamira mukuedzwa kwemumunda kushandiswa kwe grooved uye isina flangeless yakakwirira-density polyethylene (HDPE) lining tekinoroji mune kabhoni-yegore simbi mapaipi inotsanangura chirongwa cheHDPE chakabudirira chirongwa ichi. kabhoni simbi mapaipi inzira isingadhuri yekuderedza ngura yemukati mumapaipi eoiri kuburikidza nekutsaura mapaipi esimbi kubva kune zvinopisa mvura.Tekinoroji inodhura-isingadhuri pakugadzirisa ngura mukati mepombi dzeoiri.
MuADNOC, Flowlines yakagadzirirwa kupedza makore anopfuura 20. Izvi zvakakosha kuti bhizinesi rienderere mberi uye kuderedza kushandiswa kwemari.Zvisinei, kuchengetedza mitsetse iyi yakagadzirwa nekabhoni simbi inova yakaoma nokuti inotarisana nekuora kwemukati kubva mumvura inopisa, mabhakitiriya, uye mamiriro ezvinhu akadzikama anokonzerwa nekuderera kwekuyerera kwemazinga.Njodzi yekutadza kutendeseka kunowedzera nezera uye kuchinja mu reservoir fluid.
ADNOC inoshandisa mapaipi pakumanikidzwa kwe30 kusvika 50 bar, tembiricha inosvika 69°C uye kudzikiswa kwemvura kunodarika 70%, uye yatambura zviitiko zvakawanda zvekurasikirwa necontainment nekuda kwekuora kwemukati mumapombi muminda mikuru yemahombekombe. Zvinyorwa zvinoratidza kuti midziyo yakasarudzwa chete ine mapaipi emafuta anodarika 91 emusikirwo (300 kiromita 4) anosimudza mapombi emukati anodarika makiromita 300 rosion.Mamiriro ekushanda ayo akarayira kushandiswa kwekuderedza kuora kwemukati kwaisanganisira pH yakaderera (4.8-5.2), kuvapo kweCO2 (> 3%) uye H2S (> 3%), gasi / mafuta ehuwandu kupfuura 481 scf / bbl, kupisa kwemutsara kunopfuura 55 ° C, kuyerera Mutsara wekumanikidza pamusoro pe 525 psi. Kuyerera kwemvura yakadzika kupfuura 525 psi. Kuyerera kwemvura yakaderera, kuderera kwemvura yakadzika, 46 m, 46 m, 46 m² yemvura. Sulfate-reducing mabhakitiriya akakanganisawo mazano ekuderedza.Kugadzirisa nhamba dzekudonha dzinoratidza kuti mizhinji yemitsara iyi yakanga isina kunaka, uye yakawanda se 14 inodonha mukati memakore 5. Izvi zvinounza dambudziko guru sezvo rinotungamirira kumvura uye kukanganisa kunokanganisa kugadzirwa.
Kurasikirwa kwekusimba uye kudiwa kwekuyera uye rakarurama remangwana flowline kutendeseka manejimendi chirongwa chakakonzera muyedzo wemumunda weiyo slotted uye isina flangeless HDPE lining tekinoroji mu 3.0 km yeSchedule 80 API 5L Gr.B 6 inches. Streamlines kubvisa dambudziko iri.Miedzo yemumunda yakatanga kushandiswa kune 3.527 km yekabhoni yesimbi mapaipi epipeline yekuongorora 0 km.4.
Gulf Cooperation Council (GCC) huru yemafuta muArabia Peninsula yakanga yaisa HDPE liner kare 2012 yepombi dzemafuta asina kuchena uye kushandiswa kwemvura. A GCC oiri huru inoshanda pamwe chete neShell yave ichishandisa HDPE linings yemvura neoiri application kweanopfuura makore makumi maviri, uye tekinoroji yakura zvakakwana kugadzirisa pombi dzemukati.
Chirongwa cheADNOC chakatangwa muchikamu chechipiri chegore ra2011 uye chakaiswa muchikamu chechipiri che2012. Monitoring yakatanga muna Kubvumbi 2012 uye yakapedzwa muchikamu chechitatu che2017. The test spools inobva yatumirwa kuBorouge Innovation Center (BIC) kuti iongororwe uye iongororwe.Kubudirira uye kukundikana kwemaitiro akaiswa kuburikidza neHDPE liaka Liaka kugadzwa kwepilot yeHDE Liaka Liaka. ner, uye hapana liner inodonha.
Pepa SPE-192862 rinotsanangura nzira dzinobatsira mukubudirira kwemiedzo yemumunda.Chikurukuriso chiri pakuronga, kuisa mapaipi, uye kuongorora mashandiro eHDPE liners kuti uwane ruzivo runodiwa kutsvaga nzira dzekuchengetedza kuvimbika kwekushandiswa kwepaipi yeHDPE mumapaipi eoiri.Iyi tekinoroji inoshandiswa mupombi dzeoiri uye mitsetse yekufambisa.Pamusoro pemapaipi matsva emafuta emagetsi anoshandiswa. yekubvisa kutadza kuperera kwepombi nekuda kwekukuvadzwa kubva mukuora kwemukati.
Bepa rakazara rinotsanangura maitiro ekushandisa eHDPE gaskets;gasket zvinhu kusarudzwa, kugadzirira, uye kurongedza kutevedzana;kubuda kwemhepo uye kuongorora hydrostatic;annular gasi venting uye kuongorora;line commissioning;uye tsanangudzo yakadzama yemigumisiro yekuongorora mushure mekuedza.The Streamline Life Cycle Cost Analysis table inoratidzira inofungidzirwa kudhura-kushanda kwekabhoni simbi inopesana neHDPE linings kune dzimwe nzira dzokuderedza kuora, kusanganisira jekiseni remakemikari uye nguruve, kwete-metallic piping, uye bare carbon steel.Chisarudzo chekuita chechipiri chakavandudzwa chekuongorora kwemunda mushure mekuedza kwekutanga kwakashandiswa, inonyatsozivikanwa kuti inobatanidza chikamu chekutanga chekubatanidza. Flanges inotadza kutadza nekuda kwekushushikana kwekunze.Kubuda kwemaoko kunzvimbo dzeflange hakungodi kutariswa nguva nenguva, izvo zvinowedzera mari yekushandisa, asi zvinokonzeresa kuburitsa gasi kumhepo.Mukuedzwa kwechipiri, maflange akatsiviwa neakaiswa welded, flangeless majoini ane otomatiki refill system, uye rakaiswa liner ine chivharo chinovharika chinovhara kure kumagumo echiteshi.
Muyedzo wemakore mashanu unosimbisa kuti kushandiswa kweHDPE linings mumapombi esimbi kabhoni kunogona kudzikisira kuora kwemukati mumapombi eoiri nekuparadzanisa mapaipi esimbi kubva kumvura inoparadza.
Wedzera kukosha nekupa isina kukanganiswa mutsara sevhisi, kubvisa nguruve yemukati kubvisa madhipoziti uye mabhakitiriya, kuchengetedza mutengo nekubvisa kudiwa kweanorwisa-scaling makemikari uye biocides, uye kuderedza basa.
Chinangwa chebvunzo iyi chaive chekudzikisira kuora kwepombi uye kudzivirira kurasikirwa nechinhu chekutanga.
Slotted HDPE liners ane welded flangeless majoini anoshandiswa pamwe chete neiyo re-jekiseni sisitimu sekuvandudzwa kunoenderana nezvidzidzo zvakadzidzwa kubva pakatanga kutumirwa kwepachena HDPE liner ane zvimedu pane akachinjika materminal.
Maererano nekubudirira uye kukundikana kwemaitiro akaiswa kune mutyairi, hapana kuputika kwave kushumwa mupombi kubva pakuiswa.Kumwe kuongorora uye kuongororwa neBIC kwakaratidza kuderedzwa kwe 3-5% kurema mumucheka wakashandiswa, izvo zvisingakonzeri kuparara kwemakemikari mushure memakore 5 ekushandiswa. Zvimwe zvipembenene zvakawanikwa izvo hazvina kuwedzera mukuputika.Naizvozvo, zvinokurudzirwa kufunga nezvekuparara kwepakati pekugadzirisa kwemukati kunofanira kuva mutsauko mukuru wekugadzirisa. kutarisisa, uko HDPE lining sarudzo (kusanganisira yakatozivikanwa kuvandudzwa senge kutsiva flanges nezvibatanidza uye kuenderera mberi neiyo lining uye nekuisa cheki vharafu mumutsara kukunda gasi permeability ye lining) mhinduro yakavimbika.
Iyi tekinoroji inobvisa kutyisidzira kwekuora kwemukati uye inopa kuchengetedza kwakakosha mukushandisa mari panguva yekugadziriswa kwemakemikari, sezvo pasina kurapwa kwemakemikari kunodiwa.
Kusimbiswa kwemunda kwekombiyuta kwakave nemigumisiro yakanaka kune vashandi 'flowline integrity management, kupa mamwe maitiro e-proactive flowline internal corrosion management, kuderedza mari yose uye kuvandudza HSE performance.Flangeless grooved HDPE liners inokurudzirwa senzira itsva yekugadzirisa kuparara mumafuta emafuta.
HDPE lining tekinoroji inokurudzirwa kune iripo mafuta uye gasi minda uko kudonha kwepombi uye kukanganisa kwejekiseni remvura kwakajairika.
Ichi chishandiso chinoderedza huwandu hwekutadza kuyerera kunokonzerwa nekudonha kwemukati, kuwedzera hupenyu hwekuyerera, uye kuwedzera kugadzirwa.
Zvitsva zvizere zvesaiti kuvandudza zvinogona kushandisa tekinoroji iyi ye-in-line corrosion manejimendi uye kuchengetedza mutengo pazvirongwa zvekutarisa.
Ichi chinyorwa chakanyorwa neJPT Technical Edhita Judy Feder uye ine zvakanakisa kubva mubepa reSPE 192862, "Innovative Field Trial Trial Results of Flangeless Grooved HDPE Liner Application in a Super Gigantic Field yeOil Flowline Internal Corrosion Management" naAbby Kalio Amabipi, SPE, Marwan Hamad Salemhe, Gup Prasander Mukuru weAD.Mohamed Ali Awadh, Borouge PTE;Nicholas Herbig, Jeff Schell naTed Compton veUnited Special Technical Services ye2018 2018 muAbu Dhabi, November 12-15 Gadzirirai Abu Dhabi International Petroleum Exhibition uye Conference.Iri pepa harina kuongororwa nevezera.
