1 Kusimukira kwemumba nekune dzimwe nyika parizvino
Pipeline CO2 yekufambisa yakashandiswa kunze kwenyika, iine 6,000 km yemapaipi eCO2 pasi rose, ane huwandu hunopfuura 150 Mt/a.Mazhinji emapaipi eCO2 ari kuNorth America, asi mamwe ari kuCanada, Norway neTurkey.Ruzhinji rwekure-kure, hombe-yakakura CO2 mapaipi kunze kwenyika anoshandisa supercritical yekufambisa tekinoroji.
Kuvandudzwa kweCO2 pombi yekufambisa tekinoroji muChina kwanonoka, uye hapasati pave nepombi yekufambisa yedaro refu.Mapaipi aya ndeemukati memumunda wemafuta kuunganidza uye kufambisa mapaipi, uye haaonekwe CO2 mapaipi mupfungwa chaiyo.
2 Makiyi matekinoroji ekugadzirwa kwepombi yekutakura CO2
2.1 Zvinodiwa zvegasi source components
Kudzora zvinhu zvegasi zvinopinda mupombi yekufambisa, zvinotevera zvinhu zvinonyanya kutariswa: (1) kuzadzisa kudiwa kwemhando yegasi pamusika unotangwa, senge EOR kudzoreredza mafuta, chinonyanya kudiwa kuzadzisa zvinodikanwa zvemusanganiswa- phase mafuta drive.②Kuzadzisa zvinodikanwa zvekufambiswa kwepombi yakachengeteka, kunyanya kudzora zvirimo mumagasi ane muchetura seH2S uye magasi anoparadza, pamwe nekunyatso kudzora nzvimbo yedova remvura kuona kuti hapana mvura yemahara inonaya panguva yekufambisa kwepombi.(3) Kutevedzera mitemo yenyika uye yemunharaunda nemirairo pamusoro pekuchengetedzwa kwezvakatipoteredza;(4) Pahwaro hwekusangana nezvinodiwa zvitatu zvekutanga, dzikisa mutengo wegasi kurapwa kumusoro kwerwizi zvakanyanya sezvinobvira.
2.2 Kusarudzwa uye kutonga kwechikamu chekufambisa
Kuti uve nechokwadi chekuchengetedza uye kuderedza mutengo wekushandisa we CO2 pombi, zvinodikanwa kudzora pombi yepakati kuchengetedza nzvimbo yakagadzikana yechikamu panguva yekufambisa.Kuti uve nechokwadi chekuchengetedza uye kuderedza mutengo wekushandisa we CO2 mapaipi, zvinodikanwa kutanga kudzora pombi yepakati kuti uchengetedze yakagadzikana nhanho mamiriro panguva yekutapurirana, saka gasi chikamu chekufambisa kana supercritical nyika kufambisa kunowanzo kusarudzwa.Kana gasi-chikamu chekutakura chikashandiswa, kudzvinyirira hakufaniri kudarika 4.8 MPa kudzivirira kusiyana kwepakati pakati pe4.8 ne8.8 MPa uye kuumbwa kwezvikamu zviviri zvekuyerera.Zviripachena, kune yakakura vhoriyamu uye kureba CO2 mapaipi, zviri nani kushandisa supercritical kutapurirana uchifunga nezvekudyara kweinjiniya uye mutengo wekushanda.
2.3 Routing uye nharaunda hierarchy
Mukusarudzwa kwe CO2 pombi yekufambisa, mukuwedzera mukuenderana nekuronga kwehurumende yenzvimbo, kudzivirira nzvimbo dzakatipoteredza, nzvimbo dzekuchengetedza zvisaririra, nzvimbo dzenjodzi dze geological, nzvimbo dzakapoteredzwa dzemigodhi nedzimwe nzvimbo, isu tinofanirawo kutarisa kune imwe nzvimbo yepombi uye misha yakapoteredza, mataundi, maindasitiri nemabhizinesi emigodhi, nzvimbo dzakakosha dzekudzivirira mhuka, kusanganisira mafambiro emhepo, nzvimbo, kufefetera, nezvimwewo. Patinenge tichisarudza nzira, tinofanira kuongorora nzvimbo dzakakwirira dzepombi, uye panguva imwe chete tichitora dziviriro inoenderana. uye matanho ekuyambira.Pakusarudza nzira, zvinokurudzirwa kushandisa setiraiti kure inonzwa data yekuongorora terrain inundation, kuitira kuti uone iyo yakakwira mhedzisiro nzvimbo yepombi.
2.4 Nheyo dzekugadzira kamuri yevharuvhu
Kuti udzore huwandu hwekudonha kana tsaona yekutsemuka kwepombi uye kufambisa kugadziriswa kwepombi, tambo yevharuvhu yekamuri inotemwa inogarwa pane imwe chinhambwe papombi.Iyo yevhavha yekamuri spacing inotungamira kune yakakura yakawanda yekuchengetera pombi pakati pekamuri yevharuvhu uye huwandu hukuru hwekudonha kana tsaona ikaitika;iyo yevhavha yekamuri spacing idiki zvakanyanya inotungamira mukuwedzera kwekutora nyika nekudyara kweinjiniya, nepo kamuri yevharuvhu pachayo inotapukira kunzvimbo yekudonha, saka hazvisi nyore kuseta zvakanyanya.
2.5 Kusarudzwa kwekuvhara
Zvinoenderana neruzivo rwekunze mune CO2 pombi yekuvaka uye kushanda, hazvikurudzirwe kushandisa mukati coating yekudzivirira ngura kana kuderedza kushomeka.Iyo yakasarudzwa yekunze anticorrosion coating inofanira kunge iri nani yakaderera tembiricha kuramba.Munguva yekugadzira pombi mukushanda uye kuzadza kudzvanywa, chiyero chekukura kwekumanikidza chinoda kudzorwa kudzivirira kukwira kwekushisa kukuru nekuda kwekukurumidza kuwedzera kwekumanikidza, zvichikonzera kutadza kwekupfeka.
2.6 Zvinodiwa zvakakosha zvemidziyo uye zvinhu
(1) Kuisa chisimbiso kushanda kwemidziyo nemavharuvhu.(2) Mafuta ekuzora.(3) Pipe rega kutsemuka kuita.
