co2 Mass Flow Meter
Isilinganiso esinembile siqukethe umgogodla wokusebenza kahle, ukunemba kanye nokusimama emikhakheni eminingi yezimboni, emikhakheni yezemvelo kanye nezinqubo zesayensi. Isilinganiso sokugeleza kwe-CO₂ siwumgogodla wezinqubo ezithonya ukuphila kwethu kwansuku zonke neplanethi, sipelitha umehluko omkhulu phakathi kokungasebenzi kahle okuphumelelayo nokubizayo.
Izizwe Ezijwayelekile Ze-Carbon Dioxide
I-Carbon dioxide ikhona ezifundeni ezine -- igesi, uketshezi, i-supercritical futhi eqinile ingqikithi yezimo ezihlukene zokushisa nezimo zengcindezi. Noma kunjalo, lezo zifunda ezine zinikeza izinselele ezihlukene zokucubungula ukuze kufinyelelwe izinselele ezithile zokuphatha nokulinganisa.
I-carbon dioxide enegesiisetshenziswa kakhulu ekuthuthukisweni kwe-greenhouse, izinhlelo zokucisha umlilo ngisho nasekufakweni kokudla ukuze kulondolozwe isikhathi eside.I-liquid carbon dioxidekufezwa ngokubhekana nezingcindezi eziphezulu kanye namazinga okushisa aphansi, okubaluleke kakhulu ezinhlelweni ezifana ne-carbonation yesiphuzo, isiqandisi kanye nokuhamba ngomfutho ophezulu.
I-Supercritical Co2itholakala isetshenziswe ekubuyiseni uwoyela okuthuthukisiwe, ukuchithwa kwekhabhoni kanye nanjengento encibilikayo ezinqubweni zokukhipha; iqinile co2, eyaziwa ngokuthi iqhwa elomile, ngokuvamile lisetshenziselwa ukupholisa, ukulondolozwa, imiphumela ekhethekile kanye nokuhlanza izimboni.
Izinselelo ku-Measuring co2
Ngenxa yokuhluka kwayo okuhlukile ezimeni ezihlukahlukene, kunezinselele eziningi zobuchwepheshe ekulinganisweni kokugeleza, ikakhulukazi ukulinganisa okunembile kwe-gaseous co.2. Kudinga ukulungiswa njalo ukuze kufinyelelwe kumazinga okucubungula ngokucindezelwa kwawo kanye nokuzwela kwezinga lokushisa. Ngisho namaphutha amancane ekulinganiseni angabangela ukungafani okukhulu.
Izindawo zokucindezela okuphezulu kanye nengozi ye-cavitation ingase idicilele phansi ukusebenza kwamamitha okugeleza kwendabuko. Ngaphandle kwalokho, ukungcola nokushintshwa kwesigaba kwezokuthutha kuyizimbangela zamaphutha uma kwenzeka kufakwa imitha yokugeleza engalungile esilinganisweni sezimboni.
Ukuminyana nokuguquguquka kwe-viscosity kushiya ukulinganisa okunembile kuyinkimbinkimbi kakhulu kumasistimu abaluleke kakhulu, lapho amathuluzi adinga ukujwayelana nezakhiwo eziguqukayo futhi agcinwe ukunemba okudingekayo.
Imisebenzi ye-CO₂ Mass Flow Meters
Iimitha yokugeleza kwegesi ye-carbon dioxideiyithuluzi elizinikele elenzelwe ukuqapha ukugeleza kwenqwaba ye-co2ngohlelo. Inhloso yamamitha anjalo ilele ekugcineni ukunemba kwesilinganiso sokugeleza kumazinga okushisa ahlukahlukene nezingcindezi. Asetshenziswa ezimbonini eziningi, kusukela ekudleni nesiphuzo kuya kuwoyela negesi. Ngakho-ke, opharetha bayakwazi ukuqapha nokulawula i-CO2ukusetshenziswa, ukunciphisa imfucuza kanye nokuhlangabezana nezindinganiso eziqinile zezemvelo kanye nokucubungula.
Izimiso Zokusebenza ze-CO₂ Mass Flow Meter
Aimitha yokugeleza kwe-carbon dioxideikala ukugeleza okudlula ohlelweni ngokuqondile noma ngokungaqondile, okuyisilinganiso sokugeleza kwesisindo esiqondile noma esingaqondile. Njengoba nje negama layo lisho, isilinganiso sokugeleza kwesisindo esiqondile siqapha izinga lokugeleza ngokwezakhiwo ezibonakalayo ze-CO2; isilinganiso sokugeleza esingaqondile sibala ukugeleza kwenqwaba ngamapharamitha angaqondile afana nokuminyana koketshezi nezimo zokugeleza.
Isibonelo, imitha yokugeleza kwesisindo se-Coriolis kanye nemitha yokugeleza kwesisindo esishisayo zonke zingamathuluzi okulinganisa ukugeleza kwesisindo esiqondile, ukulinganisa inertia kanye nokukhishwa kokushisa kokugeleza okudlulayo. I-Differential pressure (DP) flow meter iyisibonelo sokulinganisa okungaqondile, okubonisa ukugeleza kwesisindo ngokwehla kwengcindezi. Ngokuvamile, ukulinganisa okungaqondile okusetshenziswa ekucutshungulweni kwezimboni kudinga isinxephezelo sezinga lokushisa nengcindezi ngokunemba okuphezulu.
Kafushane, amamitha okugeleza kwesisindo esingaqondile anciphisa amazinga okugeleza ngamapharamitha wesibili njengokucindezela, izinga lokushisa kanye nevolumu. Naphezu kokuhlukahluka kwawo kanye nokusebenza kahle kwezindleko, mancane ukuqondisa amamitha okugeleza kwenqwaba ngokunemba. Ngokuphambene nalokho, amamitha okugeleza kwenqwaba eqondile akala amazinga okugeleza ngokuqondile, azikho izidingo zanoma yiziphi izinxephezelo zokushisa. Ngakho-ke amamitha ashisayo noma e-Coriolis afanele izinhlelo zokusebenza eziguquguqukayo noma ezinembe kakhulu.
Imikhiqizo Enconyiwe Yesilinganiso se-CO2
I-Coriolis Flow Meter ye-CO2 Mass Flow Measurement
Imitha yokugeleza kwenqwaba ye-Coriolis isebenza ngomgomo we-inertia, okhiqizwa isisindo esinyakazayo esidlula kumashubhu adlidlizayo. Ukushintsha kwesigaba kuwumsebenzi wezinga lokugeleza okukhulu, ukufinyelela izinjongo zokulinganisa okuhlakaniphile nokunembile.
Izici Zomkhiqizo:
✤Ukunemba okuvelele phakathi kuka-0.1%
✤Isebenza ngezindlela eziningi kukho kokubili uketshezi negesi ye-CO2 yokukala
✤Okungamele ukushintshashintsha kwezinga lokushisa nokucindezela
✤ Ukuqapha okuthembekile kwesikhathi sangempela kokuminyana
Ngaphezu kwezici ezingenhla, isasebenza ekulinganisweni kokugeleza kwe-cryogenic CO2 ngesimo sayo samanzi emazingeni okushisa aphansi, ikakhulukazi ebhekene nezimo ezinzima. Ingalinganiswa ukuze ifinyelele ukunemba okuthile naphezu kwezinguquko ezisheshayo ezingeni lokushisa.
Amamitha okugeleza kwesisindo esishisayo asebenza ngokwethula ukushisa ekugelezeni kwegesi futhi alinganise umehluko wokushisa phakathi kwezinzwa ezimbili. Lokhu kwehla kwezinga lokushisa kubangelwa ukusabela kwe-endothermic njengoba i-CO2 idlula isuka kwenye inzwa iye kwenye. Izinga lokugeleza kwegesi lingabalwa ngalelo lokulahlekelwa ukushisa, okuhlobana ngokuqondile nezinga lokugeleza kwegesi.
Izici Zomkhiqizo:
✤Kusebenza esilinganisweni sokugeleza okuphansi njengokuhlolwa kwelebhu
✤Ukunikeza ukufundwa okunembile kwe-CO2 enegesi
✤Ukunakekelwa okuncane kwesakhiwo sayo esilula -- azikho izingxenye ezihambayo
✤Umklamo ohlangene nokusebenza kahle okuphezulu
Ngokuqonda izinselele zokulinganisa i-CO₂, ukukhetha imitha yokugeleza kwenqwaba efanele, nokusebenzisa izinzuzo eziyingqayizivele zobuchwepheshe obufana ne-Coriolis namamitha okugeleza okushisayo, izimboni zingakwazi ukuthuthukisa izinqubo zazo, zinciphise izindleko, futhi ziqinisekise ukuhambisana nezindinganiso zemvelo. Kungakhathaliseki ukuthi usebenzelana ne-CO₂ enegesi ekuqapheni ukungcola noma i-CO₂ ewuketshezi ekupholiseni kwezimboni, imitha yokugeleza kwenqwaba elungile iyithuluzi elibalulekile lempumelelo.
