1 Uphuhliso lwangaphakathi nolwangaphandle lukhoyo
Uthutho lwePipeline CO2 luye lwasetyenziswa phesheya, malunga ne-6,000 km ye-CO2 yemibhobho yehlabathi, enomthamo opheleleyo ongaphezu kwe-150 Mt/a.Uninzi lwemibhobho ye-CO2 ifumaneka kuMntla Melika, ngelixa ezinye ziseKhanada, eNorway naseTurkey.Uninzi lwemibhobho emide, enkulu yeCO2 kumazwe aphesheya isebenzisa ubuchwepheshe bezothutho obugqithisileyo.
Uphuhliso lwetekhnoloji yothumelo lwemibhobho yeCO2 e-China sele kusemva kwexesha, kwaye akukabikho mbhobho wothumelo lomgama omde.Le mibhobho kukuqokelelwa kwendawo yeoli yangaphakathi kunye nemibhobho yokuhambisa, kwaye ayijongwa njengemibhobho yeCO2 ngokwenyani.
2 Iiteknoloji eziphambili zoyilo lwemibhobho yothutho lweCO2
2.1 Iimfuno zamacandelo omthombo werhasi
Ukulawula amacandelo erhasi angena kumbhobho wothumelo, ezi zinto zilandelayo ziqwalaselwa ikakhulu: (1) ukuhlangabezana nemfuno yomgangatho werhasi kwimarike ekujoliswe kuyo, njengokubuyiswa kwe-oyile ye-EOR, eyona mfuno iphambili kukuhlangabezana neemfuno zomxube- inqanaba lokuqhuba ioli.②Ukuhlangabezana neemfuno zothumelo lwemibhobho ekhuselekileyo, ikakhulu ukulawula umxholo weegesi ezinetyhefu ezifana ne-H2S kunye neegesi ezidliwayo, ukongeza ekulawuleni ngokungqongqo indawo yombethe wamanzi ukuqinisekisa ukuba akukho mvula yamanzi asimahla ngexesha lokuhanjiswa kwemibhobho.(3) Ukuthobela imithetho yesizwe neyengingqi kunye nemigaqo yokhuseleko lokusingqongileyo;(4) Ngesiseko sokuhlangabezana neemfuno zokuqala ezintathu, ukunciphisa iindleko zokunyanga igesi ukuya phezulu kangangoko kunokwenzeka.
2.2 Ukukhethwa nokulawulwa kwesigaba sothutho sikarhulumente
Ukuze kuqinisekiswe ukhuseleko kunye nokunciphisa iindleko zokusebenza kombhobho we-CO2, kuyimfuneko ukulawula umbhobho ophakathi ukuze kugcinwe isimo sesigaba esizinzile ngexesha lenkqubo yokuhambisa.Ukuze kuqinisekiswe ukhuseleko kunye nokunciphisa iindleko zokusebenza zemibhobho ye-CO2, kuyimfuneko ukulawula kuqala umbhobho ophakathi ukuze kugcinwe isimo sesigaba esizinzile ngexesha lenkqubo yokuhambisa, ngoko ke ukuhanjiswa kwesigaba segesi okanye ukuhanjiswa kombuso ophezulu kukhethwe ngokubanzi.Ukuba i-gas-phase transport isetyenzisiweyo, uxinzelelo akufanele ludlule i-4.8 MPa ukuphepha ukuhluka koxinzelelo phakathi kwe-4.8 kunye ne-8.8 MPa kunye nokuqulunqwa kokuhamba kwezigaba ezimbini.Ngokucacileyo, kumthamo omkhulu kunye nomgama omde wemibhobho ye-CO2, kunenzuzo ngakumbi ukusebenzisa i-supercritical transmission ngokuqwalasela utyalo-mali lobunjineli kunye neendleko zokusebenza.
2.3 Umzila kunye noluhlu lwendawo
Ekukhetheni imibhobho yeCO2, ukongeza ekuthobeleni isicwangciso sikarhulumente wasekhaya, ukuphepha iindawo ezinobuzaza kokusingqongileyo, iindawo zokukhuselwa kwezinto zenkcubeko, imimandla yentlekele yejoloji, imimandla yemigodi etyhutyhayo kunye nezinye iindawo, kufuneka kwakhona sigxininise kwindawo enxulumene nombhobho kunye. iilali ezijikelezileyo, iidolophu, amashishini kunye namashishini emigodi, iindawo eziphambili zokhuseleko lwezilwanyana, kubandakanywa isalathiso somoya, umhlaba, umoya wokungenisa umoya, njl. kunye namanyathelo okulumkisa kwangethuba.Xa ukhetha indlela, kuyacetyiswa ukuba kusetyenziswe idatha yesathelayithi yeremote sensing kuhlahlelo lokutyhutyha umhlaba, ukuze kubonwe isiphumo sommandla ophezulu wombhobho.
2.4 Imigaqo yoyilo lwegumbi levalvu
Ukuze kulawulwe ubungakanani bokuvuza xa kusenzeka ingozi yokugqabhuka kombhobho kunye nokuququzelela ukugcinwa kombhobho, igumbi levalve elisikiweyo limiselwa ngokubanzi kumgama othile kumbhobho.Isithuba segumbi levalve siya kukhokelela kwisixa esikhulu sogcino lwemibhobho phakathi kwegumbi levalve kunye nomthamo omkhulu wokuvuza xa kusenzeka ingozi;isithuba segumbi levalve sincinci kakhulu siya kukhokelela ekwandeni kokufunyanwa komhlaba kunye notyalo-mali lobunjineli, ngelixa igumbi levalvu ngokwalo likwathandeka kwindawo yokuvuza, ngoko akulula ukuseta kakhulu.
2.5 Ukukhethwa kwengubo
Ngokutsho kwamava angaphandle kwi-CO2 yokwakhiwa kwemibhobho kunye nokusebenza, akukhuthazwa ukusebenzisa iingubo zangaphakathi zokukhusela ukubola okanye ukunciphisa ukuxhathisa.Ingubo ekhethiweyo ye-anticorrosion yangaphandle kufuneka ibe nokuchasana okungcono kweqondo lokushisa eliphantsi.Ngethuba lenkqubo yokubeka umbhobho ekusebenzeni kunye nokuzalisa uxinzelelo, izinga lokukhula koxinzelelo kufuneka lilawulwe ukuphepha ukunyuka okukhulu kweqondo lokushisa ngenxa yokunyuka ngokukhawuleza koxinzelelo, okubangelwa ukungaphumeleli kokugubungela.
2.6 Iimfuno ezizodwa zezixhobo kunye nemathiriyeli
(1) Ukutywinwa kokusebenza kwezixhobo kunye neevalvu.(2) Isithambiso.(3) Umbhobho uyeke ukuqhekeka ukusebenza.
