Zoganizira pa Kuyika ndi Mapangidwe a Carbon Dioxide Gas Transmission Piping System Projects

1 Chitukuko chapakhomo ndi chakunja chili pano

Kuyendera kwa mapaipi a CO2 kwagwiritsidwa ntchito kunja, komwe kuli pafupifupi 6,000 km ya mapaipi a CO2 padziko lonse lapansi, okhala ndi mphamvu yopitilira 150 Mt/a.Ambiri mwa mapaipi a CO2 ali ku North America, pomwe ena ali ku Canada, Norway ndi Turkey.Mapaipi ambiri akutali, akulu a CO2 kunja amagwiritsa ntchito ukadaulo wapamwamba kwambiri.

Kukula kwa ukadaulo wotumizira mapaipi a CO2 ku China kwachedwa kwambiri, ndipo panobe mapaipi okhwima opita mtunda wautali.Mapaipiwa ndi osonkhanitsa m'minda yamafuta ndi mapaipi otumizira, ndipo samatengedwa ngati mapaipi a CO2 kwenikweni.

2 Ukadaulo wofunikira pakupanga mapaipi oyendera CO2

2.1 Zofunikira pazigawo za gasi

Kuwongolera magawo agasi omwe amalowa mupaipi yotumizira, zinthu zotsatirazi zimaganiziridwa kwambiri: (1) kukwaniritsa kufunikira kwamtundu wamafuta pamsika womwe mukufuna, monga kuchira kwamafuta a EOR, chofunikira kwambiri ndikukwaniritsa zofunikira zosakanikirana- gawo mafuta drive.②Kukwaniritsa zofunikira pakufalitsa mapaipi otetezeka, makamaka kuwongolera zomwe zili mugasi wapoizoni monga H2S ndi mpweya wowononga, kuwonjezera pakuwongolera mame amadzi kuonetsetsa kuti palibe madzi aulere omwe amalowa pakadutsa mapaipi.(3) Kutsatira malamulo a dziko ndi a m'deralo ndi malamulo okhudza chitetezo cha chilengedwe;(4) Pamaziko a kukwaniritsa zofunika zitatu zoyambirira, kuchepetsa mtengo wa mankhwala gasi kumtunda mmene ndingathere.

2.2 Kusankha ndi kulamulira gawo la zoyendera

Pofuna kuonetsetsa chitetezo ndikuchepetsa mtengo wogwiritsira ntchito mapaipi a CO2, ndikofunikira kuyang'anira sing'anga yamapaipi kuti ikhale yokhazikika panthawi yotumizira.Pofuna kuonetsetsa chitetezo ndi kuchepetsa mtengo ntchito mapaipi CO2, m'pofunika choyamba kulamulira sing'anga mapaipi kukhalabe khola gawo boma pa ndondomeko kufala, kotero kufala gasi gawo kapena supercritical kufala boma ambiri amasankhidwa.Ngati kayendetsedwe ka gasi kakugwiritsidwa ntchito, kupanikizika sikuyenera kupitirira 4.8 MPa kuti tipewe kusiyana kwapakati pakati pa 4.8 ndi 8.8 MPa ndi mapangidwe a magawo awiri.Mwachiwonekere, pamapaipi akulu ndi mtunda wautali wa CO2, ndikwabwino kugwiritsa ntchito kufalitsa kopitilira muyeso poganizira ndalama zauinjiniya ndi mtengo wantchito.

2.3 Kuwongolera ndi kuwongolera madera

Posankha njira zamapaipi a CO2, kuphatikiza kutsata dongosolo la maboma am'deralo, kupeŵa malo okhudzidwa ndi chilengedwe, malo otetezedwa ndi chikhalidwe, madera a masoka achilengedwe, madera ozungulira migodi ndi madera ena, tiyeneranso kuyang'ana kwambiri malo omwe payipiyo ili ndi midzi yozungulira, matauni, mafakitale ndi mabizinesi amigodi, madera ofunika kwambiri otetezera zinyama, kuphatikizapo mayendedwe amphepo, mtunda, mpweya wabwino, ndi zina zotero. ndi machenjezo oyambilira.Posankha njira, tikulimbikitsidwa kuti mugwiritse ntchito chidziwitso cha satellite chakutali kuti muwunikire kumtunda kwamtunda, kuti mudziwe kuchuluka kwa payipi.

2.4 Mfundo za kapangidwe ka chipinda cha valve

Pofuna kuwongolera kuchuluka kwa kutayikira pakachitika ngozi ya kuphulika kwa mapaipi ndikuthandizira kukonza mapaipi, chipinda chodulira cha valve nthawi zambiri chimayikidwa patali papaipiyo.Kutaya kwa chipinda cha valve kudzatsogolera kusungirako kwakukulu kwa chitoliro pakati pa chipinda cha valve ndi kutayikira kwakukulu pamene ngozi ichitika;kusiyana kwa chipinda cha valve ndi kochepa kwambiri kudzachititsa kuti kuwonjezeka kwa nthaka ndi ndalama zaumisiri ziwonjezeke, pamene chipinda cha vavu palokha chimakondanso kutayikira, kotero sikophweka kuyika kwambiri.

2.5 Kusankhidwa kwa zokutira

Malinga ndi zochitika zakunja pakumanga ndi kugwirira ntchito kwa mapaipi a CO2, sizovomerezeka kugwiritsa ntchito zokutira zamkati poteteza dzimbiri kapena kuchepetsa kukana.Chophimba chakunja cha anticorrosion chosankhidwa chiyenera kukhala ndi kutentha kochepa kwambiri.Panthawi yogwiritsira ntchito payipi ndi kudzaza kupanikizika, kukula kwa kupanikizika kumafunika kuwongolera kuti pasakhale kutentha kwakukulu chifukwa cha kuwonjezereka kwachangu, zomwe zimapangitsa kuti zokutira kulephera.

2.6 Zofunikira zapadera pazida ndi zida

(1) Kusindikiza kwa zida ndi ma valve.(2) Mafuta.(3) Chitoliro chimasiya kugwira ntchito.
