Ungaphuza i-carbon dioxide?
一 .ukuthi isikhutha se-liquid canbon dioxide?
I-Liquid Carbon Dioxide Kubhekiswa engxenyeni kagesi ye-carbon dioxide efomini loketshezi ngaphansi kwengcindezi ephezulu kanye nokushisa okuphansi. I-Liquid Carbon Dioxide yisiqandisi esingasetshenziswa ukugcina ukudla futhi singasetshenziselwa imvula yokufakelwa. Kubuye kube yinto eluhlaza yezimboni, engasetshenziswa ukwenza i-soda ash, urea kanye nosodo.
二. Kuphi i-carbon dioxide ivela?
1. Indlela ye-calconation
Le khasi Igesi ye-Carbon Dioxide Kukhiqizwe kwinqubo ye-calcining limestone (noma i-dolomite) ekushiseni okuphezulu kugezwa ngamanzi, asuswe ukungcola futhi acindezelwe ukukhiqiza i-gaseon dioxide
2. Indlela yokubuyisa igesi ye-Fermentation
Igesi ye-carbon dioxide ekhiqizwa kwinqubo yokuvutshelwa kwe-ethanol ukukhiqizwa iyagezwa ngamanzi, ukungcola okususiwe futhi kucindezelwe ukukhiqiza igesi yekhabhoni dioxide.
3. Indlela yokubuyisa igesi yomkhiqizo
Inqubo yokukhiqiza ye-ammonia, i-hydrogen, kanye ne-ammonia eyenziwe kaningi inenqubo yokukhishwa kwe-deconburburity (okungukuthi, ukususwa kwekhabhoni dioxide engxenyeni yegesi), ngakho-ke i-carbon dioxide ku-carbon dioxide carbon dioxide.
4. Indlela yokwandisa i-Adsorption
Ngokuvamile, i-carbon dioxide yomkhiqizo isetshenziswa njengegesi eluhlaza engavuthiwe, futhi i-carbon dioxide ephezulu yokuhlanza ikhishwe esigabeni se-adsorption ngendlela yokwanda kwe-adsorption, futhi umkhiqizo uqoqwe yi-cryppion; Ingatholakala futhi yindlela ye-adsorption distillation, esebenzisa i-silica gel, i-3a isihlungo se-molecular futhi yasebenza ikhabhoni njenge-adsorbent. , ukususa ukungcola okuthile, kanye nemikhiqizo ebuhlungu ye-carbon dioxide ingakhiqizwa ngemuva kokulungiswa kabusha.
I-5. Indlela ye-Charcoal Kiln
I-Carbon Dioxide itholakala ngokucwengisisa igesi ye-Kiln Kiln negesi yokuqhekeza i-methanol.
三. I-Liquid Carbon Dioxide iba igesi?
I-Liquid Carbon Dioxide ingaguqulwa ibe yi-carbon dionbon evamile nge-vacuum distillation. Umgomo ukuthi i-carbon dioxide ye-liquid ingahanjiswa ngokuqondile ibe yigesi emazingeni okushisa aphansi kanye nengcindezi ephansi, kanye ne-molecule ephansi, kanye nama-molecule e-carbon dioxide kugesi azoba khona ekushiseni kwegesi.
四. Yini ukusetshenziswa kwe-carbon dioxide?
1. I-Carbon Dioxide ingasetshenziswa njenge-ejenti yokucisha umlilo. Lokhu kungenxa yokuthi i-carbon dioxide ayisekeli ukuhlanganiswa futhi inzima kunomoya ngaphansi kwezimo ezijwayelekile. Ukumboza ingaphezulu kwento evuthayo nge-carbon dioxide kungahlukanisa into emoyeni bese iyeka ukushiswa. Ngakho-ke, i-carbon dioxide ingahle isetshenziselwe ukucisha umlilo futhi ingumenzeli ojwayele ukucisha umlilo.
2. I-Carbon Dioxide ingasetshenziswa njengokulondolozwa. Izindawo zokugcina izimpahla zanamuhla zivame ukugcwaliswa nge-carbon dioxide ukuvikela ukudla ukuthi kungadliwa yizinambuzane, imifino ukubola, nokuthola impilo eshalofini. Gcina okusanhlamvu, izithelo nemifino.
3. I-Carbon Dioxide ingasetshenziswa njengesiqandisi. I-Solid Carbon Dioxide yilokho esikubiza ngokuthi "iqhwa elomile" futhi kusetshenziswe ngokuyinhloko njengesiqandisi. Izindiza zisetshenziselwa ukufafaza "iqhwa elomile" ezindaweni eziphakeme, ezingakhipha umphunga wamanzi emoyeni futhi zakha imvula yokufakelwa; "I-Dry Ice" nayo ingasetshenziswa njengokudla okusheshayo okulondoloziwe.
I-4. I-Carbon Dioxide nayo ingasetshenziswa ukwenza ezinye izinto embonini yamakhemikhali, njengeziphuzo zekhabhoni, ubhiya, iziphuzo ezithambile, njll.
五. Kungani i-CO2 igesi futhi amanzi uketshezi?
Ngoba inqwaba yama-molecular amaningi inkulu futhi amandla adonsela phansi phakathi kwama-molecule makhulu, ngakho-ke kunguketshezi. Ubukhulu be-carbon dioxide buncane futhi amandla adonsela phansi phakathi kwama-molecule mancane.
六. Ingabe i-CO2 ihanjiswa njengoketshezi noma igesi?
Ngokuyinhloko ukuthuthwa ngendlela ewuketshezi, ukutholakala kwengqalasizinda ekwazi ukuthutha okuphephile nokuthembekile kwe-CO2 kubalulekile kwizicelo ze-CCUS. Izinketho ezimbili eziphambili zokuthuthwa okukhulu kwe-CO2 ngamapayipi nemikhumbi. Ukuze uthole amabanga amafushane nevolumu elincane, i-CO2 nayo ingahanjiswa ngeloli noma ngojantshi, okubiza kakhulu ngethani elilodwa le-CO2 kuphela. Ukuhamba kwamapayipi kuyindlela eshibhile yokuhambisa inani elikhulu le-carbon dioxide emhlabeni, kepha izinto zokuhamba zasolwandle zincike ebangeni nasezingeni lokuhamba.
七. Beka kafushane
I-Carbon Dioxide iyigesi engenamibala nephulayo emazingeni ajwayelekile nengcindezelo. Kuyigesi ebuthakathaka ene-acid enephunga elinombala omncane wokushisa okuphezulu; Akunakugwenywa futhi kuba yi-ketshezi engenamibala futhi engenamphundla ngemuva kwe-liquefaction. Kuyigesi engenamibala nophunga ngaphansi kwezinga lokushisa elijwayelekile nengcindezi. Isihlobo segesi igesi (umoya = 1) singu-1.522 ngo-21.1 ° C no-101.3kpa, kanye nokushisa okuvumayo kungu -78.5 ° C ku-101.3kpa. Ingcindezi yeVapor (KPA): 5778 (21.1 ° C), 3385 (0 ° C), 2082 (- 16.7 ° C), 0 (--7.5 ° C). I-Persity Mesity (KG / M3): 1.833 (21.1 ° C. 101. I-3KPA), 1. 977 (0 ° C, 3KPA). Ubuningi bamanzi ashubile (kg / m3): 762 (21.1 ° C), 929 (0 ° C), 1014 (- 16.7 ° C), 1177 (- -56.9 ° C). Izinga lokushisa elibucayi lingu-31.1 ° C kanye nengcindezi ebucayi yi-7382kpa. Ubuningi obucayi bungu-468KG / M3. I-Triple Point -56.6 ° C (416KPA). Ukushisa kwamuva kokuhwamuka (KJ / KG): 234.5 (0 ° C), 276.8 (-16.7 ° C), 301.7 (-28.9 ° C). Ukushisa okushisayo kwe-fusion kungu-199KJ / KG (-56.6 ° C). I-Carbon Dioxide igesi ebuthakathaka ene-acid enephunga elinokwethenjwa kancane emazingeni okushisa aphezulu. Ekucindezelweni komkhathi, i-carbon dioxide ayinakuba khona njengoketshezi. Lapho izinga lokushisa nengcindezi liphakeme kunephuzu elikhudlwana kepha liphansi kuka-31.1 ° C, isikhutha sekhabhoni kanye negesi zikulingana esitsheni esivaliwe. I-Carbon Dioxide ayivuleki futhi ingalungisa ezinye izinsimbi ezijwayelekile phambi kwamanzi.
