Iinkalo zokusetyenziswa kwee-alloys ezikhethekileyo kwishishini lepetroleum yeepayipi zensimbi ezingenasici
Ukuhlolwa kwepetroleum kunye nophuhliso lishishini lezinto ezininzi, itekhnoloji kunye ne-capital-intensive efuna isixa esikhulu sezinto zetsimbi kunye neemveliso zetsimbi ezineempawu ezahlukeneyo kunye nokusetyenziswa. Ngokuphuhliswa kwe-ultra-deep kunye ne-ultra-inclined oil and gas sources kunye ne-oyile kunye ne-gas fields equkethe i-H2S, i-CO2, i-Cl-, njl., ukusetyenziswa kwezixhobo zensimbi ezingenasici kunye neemfuno ezichasene ne-corrosion ziyanda.
Uphuhliso lweshishini lepetrochemical ngokwalo kunye nokuhlaziywa kwezixhobo zepetrochemical ziye zabeka phambili iimfuno eziphezulu kumgangatho kunye nokusebenza kwensimbi engenasici, efuna insimbi engagqwali inganyangeki kwaye ixhathise kumaqondo obushushu aphezulu naphantsi. Iimeko aziphumli kodwa zingqongqo. Kwangaxeshanye, ishishini lepetrochemical libubushushu obuphezulu, uxinzelelo oluphezulu, kunye neshishini elinetyhefu. Yahlukile kwamanye amashishini. Imiphumo yokusetyenziswa okuxubeneyo kwezinto azibonakali. Nje ukuba umgangatho wezinto zensimbi ezingenasici kwishishini lepetrochemical awunakuqinisekiswa, iziphumo ziya kuba yintlekele. Ngoko ke, iinkampani zensimbi ezingenasici zasekhaya, ngakumbi iinkampani zemibhobho yensimbi, kufuneka ziphucule umxholo wobugcisa kunye nexabiso elongezelelweyo leemveliso zabo ngokukhawuleza ukuba zihlale kwimarike yemveliso ephezulu.
Imarike enokubakho kwishishini lepetrochemical yimibhobho enobubanzi obukhulu kwiziko lokukrazula ioyile kunye nemibhobho yokuhambisa iqondo lobushushu eliphantsi. Ngenxa yeemfuno zabo zokumelana nobushushu obukhethekileyo kunye nokumelana nokufakwa kunye nokugcinwa kwezixhobo ezingathandekiyo, izixhobo kufuneka zibe nomjikelo wobomi benkonzo ende, kunye neempawu zoomatshini kunye nokusebenza kwemibhobho kufuneka ziphuculwe ngokulawulwa kokwakheka kwezinto kunye neendlela ezizodwa zonyango lobushushu. . Enye imarike enokwenzeka yimibhobho yentsimbi ekhethekileyo yoshishino lwesichumisi (i-urea, isichumiso se-phosphate), amanqanaba aphambili entsimbi yi-316Lmod kunye ne-2re69.
Iqhele ukusetyenziswa kwiireactors kwizixhobo zepetrochemical, imibhobho ye-oyile yequla, iinduku ezipolishiweyo kwimithombo yeoli eyonakalisayo, imibhobho ejikelezayo kwiziko le-petrochemical, kunye neenxalenye kwisixhobo sokomba ioyile negesi, njl.
