Cov pa roj carbon dioxide siv hauv cov ncauj lus kom ntxaws
Cov pa roj carbon dioxide (CO₂), uas yog cov tshuaj lom neeg, muaj ntau yam kev siv hauv ntau lub lag luam. Txawm hais tias nws yog nyob rau hauv kev tsim khoom, kev ua zaub mov, lossis kev kho mob, kev siv cov pa roj carbon dioxide tsis tuaj yeem tsis quav ntsej. Hauv tsab xov xwm no, peb yuav tham txog kev nthuav dav ntawm kev siv cov pa roj carbon dioxide hauv ntau qhov chaw thiab nws qhov tseem ceeb.
1 Kev siv cov pa roj carbon dioxide hauv kev lag luam
1.1 Chemical synthesis
Cov pa roj carbon dioxide muaj txoj haujlwm tseem ceeb hauv kev lag luam tshuaj. Nws yog ib qho tseem ceeb raw khoom rau synthesis ntawm cov tshuaj, xws li methanol thiab urea. Los ntawm cov tshuaj tiv thaiv catalytic, carbon dioxide tuaj yeem cuam tshuam nrog lwm cov tebchaw los tsim cov khoom muaj txiaj ntsig zoo. Cov pa roj carbon dioxide kuj tseem siv rau hauv kev tsim cov polycarbonate, cov yas siv dav hauv cov khoom siv hluav taws xob thiab cov khoom siv hauv tsev.
1.2 Hlau ua
Cov pa roj carbon dioxide yog siv los ua cov roj tiv thaiv hauv kev ua hlau, tshwj xeeb tshaj yog thaum vuam. Cov pa roj carbon dioxide tiv thaiv cov hlau los ntawm kev hnov ​​​​mob nrog oxygen hauv huab cua thaum lub sij hawm vuam, yog li txo cov vuam tsis xws luag thiab txhim kho qhov zoo ntawm vuam. Cov pa roj carbon dioxide kuj tseem siv rau hauv cov hlau txiav thiab cov txheej txheem txias los pab txhim kho kev ua haujlwm ntawm kev txiav thiab txuas cov cuab yeej siv lub neej.
2. Kev siv cov pa roj carbon dioxide hauv kev lag luam zaub mov thiab dej haus
2.1 Carbonated dej haus
Kev paub zoo tshaj plaws ntawm kev siv carbon dioxide hauv kev lag luam khoom noj khoom haus yog nyob rau hauv kev tsim cov dej haus carbonated. Los ntawm dissolving carbon dioxide nyob rau hauv dej, qab ntxiag carbonated npuas yuav ua tau, ua rau muaj ntau yam carbonated dej haus xws li dej qab zib thiab dej qab zib. Daim ntawv thov no tsis tsuas yog txhim kho cov saj ntawm cov dej haus, tab sis kuj muab cov dej haus ib qho kev sib tw ua lag luam tshwj xeeb.
2.2 Kev txuag zaub mov
Ntxiv nrog rau cov dej haus carbonated, cov pa roj carbon dioxide kuj tseem siv rau hauv cov ntim khoom noj. Los ntawm kev siv cov pa roj carbon dioxide rau lub ntim ntim, kev loj hlob ntawm cov kab mob hauv cov zaub mov tuaj yeem cuam tshuam thiab lub txee lub neej ntawm cov zaub mov tuaj yeem txuas ntxiv. Txoj kev no yog qhov tshwj xeeb tshaj yog thaum ntim cov zaub tshiab, nqaij thiab ntses.
3. Kev siv cov pa roj carbon dioxide hauv kev kho mob thiab kev siv ib puag ncig
3.1 Cov ntawv thov kho mob
Cov pa roj carbon dioxide kuj tau siv dav hauv kev kho mob. Piv txwv li, carbon dioxide yog siv los ua cov roj insufflating rau lub plab kab noj hniav thaum lub sij hawm endoscopic phais los pab cov kws kho mob pom thiab ua hauj lwm zoo dua. Cov pa roj carbon dioxide kuj tseem siv los tswj kev ua pa ntawm cov neeg mob, pab tswj cov qib carbon dioxide kom tsim nyog thaum muaj kev phais tshwj xeeb.
3.2 Kev siv ib puag ncig
Cov pa roj carbon dioxide kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv ib puag ncig. Piv txwv li, carbon dioxide ntes thiab khaws cia (CCS) thev naus laus zis yog ib qho tseem ceeb ntawm kev txo cov pa hluav taws xob hauv tsev cog khoom. Cov cuab yeej no txo ​​cov concentration ntawm carbon dioxide nyob rau hauv cov huab cua los ntawm kev ntes thiab txhaj tshuaj industrially generated carbon dioxide rau hauv av, yog li mitigating ntiaj teb no warming.
4. Cov lus xaus
Cov pa roj carbon dioxide muaj ntau yam kev siv, npog ntau yam xws li kev lag luam, khoom noj, tshuaj thiab kev tiv thaiv ib puag ncig. Raws li cov peev txheej, cov pa roj carbon dioxide tsis tsuas yog ua lub luag haujlwm tseem ceeb hauv kev lag luam ib txwm muaj, tab sis kuj qhia txog kev siv dav dav hauv cov thev naus laus zis tshiab. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, kev siv cov pa roj carbon dioxide yuav nthuav dav ntxiv, muab kev txhawb nqa ntau dua rau kev tsim kho ntawm ntau yam kev lag luam.
