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 high-density polyethylene (HDPE) lining tekinoroji mumapepa kabhoni simbi inotsanangura chirongwa chakabudirira. HDPE linings mucarbon steel pombi inzira isingadhuri yekudzikisa kukoromoka kwemukati mumapombi eoiri kuburikidza nekutsaura mapaipi esimbi kubva kumvura inoparadza.Tekinoroji iyi 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 mumapaipi muminda mikuru yemahombekombe. Zvinyorwa zvinoratidza kuti midziyo yakasarudzwa chete ine mapaipi anodarika 91 emafuta echisikigo anodarika 91 uye mapombi anopfuura makiromita 300 (mapaipi 300 makiromita 4) ine kuora kwakanyanya kwemukati.Mamiriro ekushanda akarayira kushandiswa kwekudzikisa kwemukati kunosanganisira pH yakaderera (4.8-5.2), kuvapo kwe CO2 (> 3%) uye H2S (> 3%), gasi / mafuta chiyero chikuru kupfuura 481 scf / bbl, kutsetseka kwemutsara kunopfuura 55 ° C, kuyerera Mutsara wekumanikidza pamusoro pe525 psi. mvura yakadzikama, uye kuvapo kwebhakitiriya inoderedza sulfate kwakakanganisawo mazano ekuderedza.Kufambisa nhamba yekuputika kunoratidza kuti yakawanda yemitsara iyi yakanga isina kunaka, uye yakawanda seye 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 chegore ra 2017. Ma test spools anobva atumirwa kuBorouge Innovation Center (BIC) kuti aongororwe uye kuongororwa.Kubudirira uye kukundikana kwezvipimo zvakagadzirirwa mushure mekugadzika kwepilot gamener leaka ye HDPE leakan kuburikidza neiyo HDPE liner, uye hapana liner inodonha.
Pepa SPE-192862 rinotsanangura nzira dzinobatsira mukubudirira kwemiedzo yemumunda.Chikurukuriso chiri pakuronga, kuisa mapaipi, uye kuongorora kushanda kweHDPE liners kuti uwane ruzivo runodiwa kutsvaga nzira dzekuchengetedza kuvimbika kwekushandiswa kwepasi rose kweHDPE mapaipi mumapaipi emafuta.Iyi tekinoroji inoshandiswa mumapombi emafuta uye mitsetse yekufambisa.Pamusoro pemapaipi matsva emafuta emafuta asina HDPE anoshandiswa. Mapaipi.Iratidza maitiro akanakisa ekubvisa 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 yekuedzwa kwemashure.The Streamline Life Cycle Cost Analysis table inoratidzira inofungidzirwa mari-inoshanda yecarbon steel marine HDPE linings kune dzimwe nzira dzokuderedza kuora, kusanganisira makemikari jekiseni uye nguruve, kwete-metallic pombi, uye bare carbon steel.Chisarudzo chekuita chechipiri chekusimudzira munda bvunzo mushure mekuedzwa kwekutanga kwakashandiswawo kubatanidza chikamu chekutanga chekubatanidza chakatsanangurwa zvakare. Zvinonyatsozivikanwa kuti maflanges anotadza kukundikana nekuda kwekunetseka kwekunze.Kupinda munzvimbo dzeflange hakudi kungotariswa nguva nenguva, izvo zvinowedzera mari yekushandisa, asi zvinokonzeresa kubuda kwegasi kumhepo. Muchiedzo chechipiri, maflange akatsiviwa nemawelded, ma-flangeless ekubatanidza ane otomatiki refill system, uye chiteshi chinodzima chine chinomira chinomira pamhepo. rakavharwa drain.
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 akagadzirirwa mutyairi, hapana kuputika kwakataurwa mupombi kubva pakuiswa.Kumwe kuongorora uye kuongororwa neBIC kwakaratidza 3-5% kuderedza uremu mumucheka wakashandiswa, izvo zvisingakonzeri kuparara kwemakemikari mushure memakore 5 ekushandiswa. Zvimwe zvipembenene zvakawanikwa izvo hazvina kuwedzera mukuputika.Naizvozvo, zvinokurudzirwa kufunga nezvekurasikirwa kwekugadziriswa kwemukati mune ramangwana. zvipingamupinyi zvinofanirwa kunge zviri izvo zvinonyanya kutariswa, uko HDPE lining sarudzo (kusanganisira yakatozivikanwa kuvandudzwa sekutsiva maflange nemaakoneti uye kuenderera mberi neiyo lining uye nekuisa cheki vharafu mumucheka kuti ukunde gasi kupera kweiyo 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 ekugadzirisa kuyerera kwemukati mukati mekugadzirisa corrosion, kuderedza mari yose nekuvandudza 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.
