mukhoza kumwa madzi carbon dioxide?
一.Kodi carbon dioxide yamadzimadzi ndi chiyani?
Madzi a carbon dioxide amatanthauza liquefaction wa mpweya woipa wa carbon dioxide mu madzi mawonekedwe pansi pa kuthamanga kwambiri ndi kutentha otsika. Liquid carbon dioxide ndi firiji yomwe ingagwiritsidwe ntchito kusunga chakudya komanso ingagwiritsidwe ntchito popanga mvula yopangira. Ndizinthu zopangira mafakitale, zomwe zingagwiritsidwe ntchito kupanga phulusa la soda, urea ndi soda.
二.Kodi carbon dioxide imachokera kuti?
1. Njira yowerengera
The mpweya wa carbon dioxide opangidwa m`kati calcining miyala yamchere (kapena dolomite) pa kutentha osambitsidwa ndi madzi, kuchotsedwa zonyansa ndi wothinikizidwa kutulutsa mpweya mpweya woipa.
2. njira nayonso mphamvu mpweya kuchira
Mpweya wa carbon dioxide wopangidwa mu fermentation wa kupanga ethanol umatsukidwa ndi madzi, zonyansa zimachotsedwa ndi kukakamizidwa kuti zipange mpweya woipa.
3. Njira yobwezeretsa gasi ndi mankhwala
The ndondomeko kupanga ammonia, wa hydrogen, ndi kupanga ammonia zambiri ndondomeko decarburization (ndiko kuti, kuchotsa mpweya woipa mu mpweya osakaniza), kuti mpweya woipa mu mpweya wosakaniza akhoza odzipereka pansi pa mavuto, decompressed ndi kutentha kupeza mkulu-chiyero mpweya woipa mpweya woipa.
4. Adsorption njira yowonjezera
Nthawi zambiri, mpweya woipa wa carbon dioxide umagwiritsidwa ntchito ngati mpweya wopangira, ndipo mpweya wochuluka wa carbon dioxide umachokera ku gawo la adsorption ndi njira yowonjezera yowonjezera, ndipo mankhwalawa amasonkhanitsidwa ndi cryopump; Itha kupezekanso ndi njira ya adsorption distillation, yomwe imagwiritsa ntchito silika gel, 3A molecular sieve ndi activated carbon ngati adsorbent. , kuchotsa zonyansa zina, ndi zinthu za carbon dioxide zaukhondo zimatha kupangidwa pambuyo pozikonza.
5. Njira yowotchera makala
Mpweya woipa wa carbon dioxide umapezeka poyenga mpweya wamoto wa makala ndi mpweya wosweka wa methanol.
三. Kodi Liquid Carbon Dioxide Amakhala Gasi Motani?
Mpweya wa carbon dioxide ukhoza kusinthidwa kukhala mpweya wabwino wa carbon dioxide ndi vacuum distillation. Mfundo ndi yakuti madzi carbon dioxide akhoza mwachindunji chamunthuyo mu mpweya pa kutentha otsika ndi otsika kuthamanga, ndi mamolekyu carbon dioxide mu mpweya adzakhalapo mu kutentha ndi kuthamanga boma kutentha firiji.
四. Kodi madzi a carbon dioxide amagwiritsidwa ntchito bwanji?
1. Mpweya wa carbon dioxide ungagwiritsidwe ntchito ngati chozimitsira moto. Izi zili choncho chifukwa mpweya woipa suthandiza kuyaka ndipo ndi wolemera kuposa mpweya nthawi zonse. Kuphimba pamwamba pa chinthu choyaka ndi carbon dioxide kungathe kusiyanitsa chinthucho ndi mpweya ndikusiya kuyaka. Choncho, mpweya woipa ukhoza kugwiritsidwa ntchito kuzimitsa moto ndipo ndi chinthu chozimitsa moto chomwe chimagwiritsidwa ntchito kwambiri.
2. Mpweya wa carbon dioxide ukhoza kugwiritsidwa ntchito ngati chosungira. Malo osungira amakono nthawi zambiri amadzazidwa ndi mpweya woipa kuti chakudya chisadyedwe ndi tizilombo, ndiwo zamasamba kuti ziwole, ndi kuwonjezera moyo wa alumali. Sungani mbewu, zipatso ndi ndiwo zamasamba.
3. Mpweya wa carbon dioxide ukhoza kugwiritsidwa ntchito ngati firiji. Mpweya wokhazikika wa carbon dioxide ndi umene timautcha kuti "dry ice" ndipo umagwiritsidwa ntchito makamaka ngati firiji. Ndege zimagwiritsidwa ntchito kupopera "madzi oundana" pamalo okwera, omwe amatha kusungunula nthunzi yamadzi mumlengalenga ndikupanga mvula yochita kupanga; "Dry ayezi" angagwiritsidwenso ntchito ngati chakudya mwamsanga kuzizira.
4. Mpweya wa carbon dioxide ungagwiritsidwenso ntchito popanga zinthu zina zamakampani monga zakumwa za carbonated, moŵa, zakumwa zoziziritsa kukhosi, ndi zina zotero.
五. Chifukwa chiyani CO2 ndi gasi ndi madzi ndi madzi?
Chifukwa wachibale molecular unyinji wa madzi ndi lalikulu ndi mphamvu yokoka pakati mamolekyu ndi yaikulu, choncho ndi madzi. Kuchuluka kwa carbon dioxide ndi kochepa ndipo mphamvu yokoka pakati pa mamolekyu ndi yaying'ono.
六. Kodi CO2 imatengedwa ngati madzi kapena gasi?
Zonyamulidwa makamaka mu mawonekedwe amadzimadzi, kupezeka kwa zomangamanga zomwe zimatha kuyenda bwino komanso zodalirika za CO2 ndizofunika kwambiri pa ntchito za CCUS. Njira ziwiri zazikulu zoyendetsera CO2 ndi mapaipi ndi zombo. Kwa zoyendera zazifupi komanso zazing'ono, CO2 imathanso kuperekedwa ndi galimoto kapena njanji, yomwe ndi yokwera mtengo pa toni ya CO2 yokha. Kuyendera mapaipi ndi njira yotsika mtengo kwambiri yonyamulira mpweya wochuluka wa carbon dioxide pamtunda, koma mayendedwe apanyanja amadalira mtunda ndi kukula kwa mayendedwe.
七. Fotokozerani mwachidule
Mpweya woipa wa carbon dioxide ndi mpweya wopanda mtundu komanso wopanda fungo womwe umatenthedwa bwino komanso ukapanikizika. Ndi mpweya wochepa wa acidic wokhala ndi fungo lopweteka pang'ono pa kutentha kwakukulu; sichikhoza kuyaka ndipo chimakhala chamadzimadzi chosakhala ndi mtundu komanso chosanunkha pambuyo pothira. Ndi mpweya wopanda mtundu komanso wopanda fungo womwe umatenthedwa bwino komanso kupanikizika. Kuchuluka kwa gasi (mpweya = 1) ndi 1.522 pa 21.1 ° C ndi 101.3kPa, ndipo kutentha kwa sublimation ndi -78.5 ° C pa 101.3kPa. Kuthamanga kwa nthunzi (kPa): 5778 (21.1°C), 3385 (0°C), 2082 (- 16.7°C), 416 (-56.5°C), 0 (-78.5°C). Kuchuluka kwa mpweya (kg/m3): 1.833 (21.1 ° C. 101. 3kPa), 1. 977 (0 ° C, 101. 3kPa). Kuchuluka kwamadzimadzi okhathamira (kg/m3): 762 (21.1°C), 929 (0°C), 1014 (- 16.7°C), 1070 (- 28.9°C), 1177 (-56.6°C). Kutentha kwakukulu ndi 31.1 ° C ndipo kupanikizika kwakukulu ndi 7382kPa. Kuchulukana kwakukulu ndi 468kg/m3. Malo atatu -56.6°C (416kPa). Kutentha kobisika kwa nthunzi (kj/kg): 234.5 (0°C), 276.8 (-16.7°C), 301.7 (-28.9°C). Kutentha kobisika kwa maphatikizidwe ndi 199kj/kg (-56.6°C). Mpweya woipa wa carbon dioxide ndi mpweya wochepa wa acidic wokhala ndi fungo lopweteka pang'ono pa kutentha kwakukulu. Pa kuthamanga kwa mumlengalenga, mpweya woipa sungakhalepo ngati madzi. Kutentha ndi kupanikizika kukakwera kuposa katatu koma kutsika kuposa 31.1 ° C, mpweya woipa ndi mpweya zimakhala zofanana mu chidebe chotsekedwa. Mpweya woipa wa carbon dioxide sukhoza kuyaka ndipo ukhoza kuwononga zitsulo zina wamba pakakhala madzi.
