Imitha Yokugeleza Kwesisindo se-CO2
Ukulinganisa okunembile kuyisisekelo sokusebenza kahle, ukunemba kanye nokusimama emikhakheni eminingi yezimboni, imikhakha yezemvelo kanye nezinqubo zesayensi. Ukulinganisa ukugeleza kwe-CO₂ kuyisisekelo sezinqubo ezithonya izimpilo zethu zansuku zonke kanye neplanethi yethu, okuchaza umehluko omkhulu phakathi kokungasebenzi kahle okuphumelelayo nokubizayo.
Izimo Ezijwayelekile Ze-Carbon Dioxide
I-carbon dioxide ikhona ezimweni ezine -- igesi, uketshezi, okubaluleke kakhulu kanye nokuqinile sekukonke ezimweni zokushisa nezingcindezi ezahlukahlukene. Noma kunjalo, lezo zifundazwe ezine ziletha izinselele zokucubungula ezihlukile ukuze kufinyelelwe izinselele ezithile zokuphatha nokulinganisa.
I-carbon dioxide enegesiisetshenziswa kabanzi ekukhuliseni ukushisa, izinhlelo zokuvimbela umlilo ngisho nasekupakisheni ukudla ukuze kulondolozwe isikhathi eside.I-carbon dioxide ewuketshezikufezwa ngokubhekana nokucindezeleka okuphezulu kanye namazinga okushisa aphansi, okubaluleke kakhulu ekusetshenzisweni okufana nokufakwa kwe-carbon ephuzweni, ukubanda kanye nokuthuthwa okunomfutho ophezulu.
I-supercritical co2itholakala isetshenziswa ekubuyiselweni kwamafutha okuthuthukisiwe, ekuthuthweni kwekhabhoni kanye nanjengesinyibilikisi ezinqubweni zokukhipha; i-solid co2, eyaziwa ngokuthi iqhwa elomile, ivame ukusetshenziswa ekupholiseni, ekulondolozeni, emiphumeleni ekhethekile nasekuhlanzeni kwezimboni.
Izinselele Ekulinganiseni i-co2
Ngenxa yokwehluka kwayo okuhlukile ezimweni ezahlukene, kunezinselele eziningi zobuchwepheshe ekulinganisweni kokugeleza, ikakhulukazi ukulinganisa okunembile kwe-gaseous co.2Kudinga ukulungiswa okuqhubekayo ukuze kufinyelelwe amazinga okucubungula ngokucindezelwa kwayo kanye nokuzwela kwezinga lokushisa. Ngisho namaphutha amancane ekulinganisweni angabangela ukungafani okukhulu.
Izindawo ezinomfutho ophezulu kanye nengozi yokufakwa kwe-cavitation kungalimaza ukusebenza kwamamitha okugeleza endabuko. Ngaphandle kwalokho, ukungcola kanye nokushintsha kwesigaba ekuthuthweni kuyizimbangela zamaphutha uma kufakwa imitha yokugeleza engalungile ekulinganisweni kwezimboni.
Ubuningi kanye nokuguquguquka kwe-viscosity kushiya ukulinganisa okunembile kuyinkimbinkimbi kakhulu ezinhlelweni ezibucayi kakhulu, lapho izinsimbi kudingeka zilungiswe ukuze zibe nezakhiwo eziguquguqukayo futhi zigcinwe zinembile.
Imisebenzi Yamamitha Okugeleza Kwesisindo Se-CO₂
Iimitha yokugeleza kwegesi ye-carbon dioxideiyithuluzi elizinikele elenzelwe ukuqapha ukugeleza okukhulu kwe-co2ngokusebenzisa uhlelo. Inhloso yamamitha anjalo iwukugcina ukunemba kokulinganiswa kokugeleza emazingeni okushisa ahlukahlukene kanye nokucindezela. Asetshenziswa ezimbonini eziningi, kusukela ekudleni naseziphuzweni kuya ku-oyili negesi. Ngakho-ke, abaqhubi bayakwazi ukuqapha nokulawula i-CO22ukusetshenziswa, ukunciphisa imfucuza kanye nokuhlangabezana nezindinganiso eziqinile zemvelo kanye nokucubungula.
Izimiso Zokusebenza ze-CO₂ Mass Flow Meter
Aimitha yokugeleza kwe-carbon dioxideilinganisa ukugeleza okudlula ohlelweni ngokuqondile noma ngokungaqondile, okungukuthi ukulinganisa ukugeleza kwesisindo okuqondile noma okungaqondile. Njengoba nje igama layo lisho, ukulinganisa ukugeleza kwesisindo okuqondile kuqapha izinga lokugeleza ngokwezakhiwo zomzimba ze-CO2; ukulinganisa ukugeleza okungaqondile kubala ukugeleza kwesisindo ngamapharamitha angaqondile njengobuningi boketshezi kanye nezimo zokugeleza.
Isibonelo, imitha yokugeleza kwesisindo se-Coriolis kanye nemitha yokugeleza kwesisindo sokushisa konke kungamadivayisi okulinganisa ukugeleza kwesisindo okuqondile, ukulinganisa i-inertia kanye nokushabalalisa ukushisa kokugeleza okudlulayo. Imitha yokugeleza yengcindezi ehlukile (DP) iyisibonelo sokulinganisa okungaqondile, okunquma ukugeleza kwesisindo ngokwehla kwengcindezi. Ngokuvamile, ukulinganisa okungaqondile okusetshenziswa ekucutshungulweni kwezimboni kudinga isinxephezelo sokushisa kanye nengcindezi ukuze kube nokunemba okuphezulu.
Ngamafuphi, amamitha okugeleza kobuningi angaqondile anquma amazinga okugeleza ngokusebenzisa amapharamitha esibili njengokucindezela, izinga lokushisa kanye nevolumu. Naphezu kokuguquguquka kwawo kanye nokusebenza kahle kwezindleko, aphansi ekuqondiseni amamitha okugeleza kobuningi ngokunemba. Ngokuphambene nalokho, amamitha okugeleza kobuningi aqondile alinganisa amazinga okugeleza ngqo, awekho isidingo sokunciphisa izinga lokushisa. Ngakho-ke amamitha okushisa noma e-Coriolis afanele ukusetshenziswa okuguquguqukayo noma okunembe kakhulu.
Imikhiqizo Enconyiwe Yokulinganisa i-CO2
Imitha Yokugeleza kweCoriolis Yokulinganisa Ukugeleza Kwesisindo se-CO2
Imitha yokugeleza kobuningi beCoriolis isebenza ngesimiso se-inertia, esikhiqizwa yisisindo esihambayo esidlula emashubhini adlidlizayo. Ukushintsha kwesigaba kuwumsebenzi wesilinganiso sokugeleza kobuningi, okufinyelela izinjongo zokulinganisa okuhlakaniphile nokunembile.
Izici Zomkhiqizo:
✤Ukunemba okuvelele ngaphakathi kuka-0.1%
✤Isebenziseka ngezindlela eziningi kokubili ekulinganisweni kwe-CO2 okuwuketshezi kanye negesi
✤ Akunandaba nokushintshashintsha kwezinga lokushisa kanye nengcindezi
✤ Ukuqapha ubuningi obuthembekile besikhathi sangempela
Ngaphezu kwezici ezingenhla, isasebenza ekulinganisweni kokugeleza kwe-CO2 okubangelwa yi-cryogenic ngesimo sayo soketshezi emazingeni okushisa aphansi, ikakhulukazi egxile ekumelaneni nezimo ezimbi kakhulu. Ingalinganiswa ukuze ifinyelele ukunemba okuthile naphezu kokushintsha okusheshayo kwezinga lokushisa.
Amamitha okugeleza kwesisindo sokushisa asebenza ngokungenisa ukushisa ekugelezeni kwegesi futhi alinganise umehluko wokushisa phakathi kwezinzwa ezimbili. Lokhu kwehla kwezinga lokushisa kubangelwa ukusabela kwe-endothermic njengoba i-CO2 idlula kusuka kwesinye isenzwa iye kwesinye. Izinga lokugeleza kwegesi lingabalwa ngokwelokulahlekelwa ukushisa, okuhlobene ngqo nezinga lokugeleza kwegesi.
Izici Zomkhiqizo:
✤Isebenza ekulinganisweni kokugeleza okuphansi njengokuhlolwa kwelebhu
✤Ukunikeza ukufundwa okunembile kwe-CO2 yegesi
✤Ukulungiswa okuncane kwesakhiwo sayo esilula -- azikho izingxenye ezihambayo
✤Umklamo omncane kanye nokusebenza kahle okuphezulu
Ngokuqonda izinselele zokulinganisa i-CO₂, ukukhetha imitha yokugeleza kwesisindo efanele, nokusebenzisa izinzuzo ezihlukile zobuchwepheshe ezifana ne-Coriolis kanye namamitha okugeleza okushisa, izimboni zingenza ngcono izinqubo zazo, zinciphise izindleko, futhi ziqinisekise ukuhambisana nezindinganiso zemvelo. Kungakhathaliseki ukuthi ubhekene ne-CO₂ yegesi ekuqapheni ukukhishwa kwegesi noma i-CO₂ ewuketshezi ekupholiseni kwezimboni, imitha yokugeleza kwesisindo efanele iyithuluzi elibalulekile lempumelelo.
