Qhov sib txawv tseem ceeb ntawm methane thiab fluorinated gases yog tias methane yog cov roj tsev cog khoom uas tuaj yeem tsim tau los yog tsim ib txwm muaj, hos cov roj fluorinated yog tib neeg tsim tsev cog khoom gases.

Ob lub methane thiab fluorinated gases yog cov roj tsev cog khoom. Cov nyhuv tsev cog khoom piav qhia txog qhov nce ntxiv ntawm atmospheric cua sov vim qhov ntxiab ntawm tshav kub uas los ntawm lub hnub. Greenhouse gases yog cov khoom uas tuaj yeem cuam tshuam qhov cua sov no.

Methane yog dab tsi?

Methane yog lub tsev cog khoom loj loj uas muaj cov tshuaj CH 4Kev tsim thiab thauj cov thee, nkev, thiab roj yog cov khoom loj uas tso cai rau cov roj methane nkag mus. qhov cua. Tib neeg cov dej num xws li kev xau los ntawm cov tshuab hluav taws xob thiab kev tsim cov tsiaj nyeg kuj ua rau muaj cov ntsiab lus methane hauv huab cua.

Ntxiv mus, methane cov ntaub ntawv nyob rau hauv tej qhov chaw xws li tej yam ntuj tso ntub dej, ntuj txheej txheem nyob rau hauv av thiab tshuaj lom neeg cov tshuaj nyob rau hauv cov huab cua. Thaum muab piv nrog cov pa roj carbon dioxide (uas yog lwm lub tsev cog khoom loj), lub neej ntawm methane hauv huab cua yog luv dua. Txawm li cas los xij, cov roj methane muaj txiaj ntsig zoo dua hauv kev cuam tshuam hluav taws xob, uas ua rau kom muaj cua sov. Yog li ntawd, methane muaj kev sib piv ntau dua li cov pa roj carbon dioxide.

Cov fluorinated Gases yog dab tsi?

fluorinated gases lossis F-gases yog cov pa hluav taws xob muaj zog tshaj plaws uas tawm los ntawm tib neeg kev ua ub no. Cov no yog cov neeg tsim cov tebchaw uas tuaj yeem nyob hauv qhov chaw rau lub sijhawm ntev (txawm ntau pua xyoo). Muaj plaub hom F-gases, suav nrog hydrofluorocarbon (HFC), perfluorocarbon (PFC), sulfur hexafluoride (SF6), thiab nitrogen fluoride (NF3). Ntawm lawv, F-gases feem ntau tshwm sim thiab teeb meem loj yog cov pa roj carbon monoxide hydrofluorocarbon. Cov pa roj no muaj hydrogen, fluorine thiab carbon atoms. Cov kev siv loj ntawm HFC gases yog cov tub yees, cua txias, cov khoom siv twj tso kua mis, thiab ua cov tshuab ua npuas ncauj. Cov F-gases no kuj raug tso tawm thaum siv hluav taws tua hluav taws, aerosol propellants, thiab cov kuab tshuaj.

Ntxiv mus rau HFC cov pa roj, cov pa hluav taws xob perfluorocarbon yog cov pa roj carbon monoxide thib ob. Cov molecules no muaj fluorine thiab carbon atoms. Peb siv cov roj no feem ntau hauv cov khoom siv hluav taws xob, tshuaj pleev ib ce, kev lag luam tshuaj, thiab lwm yam. Tsis tas li ntawd, cov roj no kuj tseem siv tau hauv cov tub yees thaum sib xyaw nrog lwm cov roj. Thaum txiav txim siab sulfur hexafluoride, nws feem ntau yog siv los ua cov roj hluav taws xob. Nws yog siv nyob rau hauv zus tau tej cov magnesium thiab kuj muaj nyob rau hauv high voltage switchgear. Txawm li cas los xij, raws li Montreal Protocol, kev siv cov pa roj no tam sim no raug txwv vim muaj kev cuam tshuam ib puag ncig; Cov roj fluorinated no tuaj yeem ua rau cov txheej txheej ozone puas tsuaj heev.

Qhov txawv ntawm Methane thiab Fluorinated Gases yog dab tsi?

Methane thiab fluorinated gases yog ob lub tsev cog khoom loj. Qhov sib txawv tseem ceeb ntawm methane thiab fluorinated gases yog tias methane yog lub tsev cog khoom roj uas tuaj yeem tsim cov khoom tsim los yog cov ntaub ntawv ib txwm muaj, whereas fluorinated gases yog tib neeg tsim tsev cog khoom gases. Tsis tas li ntawd, methane muaj lub neej luv luv nyob rau hauv cov huab cua thaum fluorinated gasses muaj lub neej ntev heev hauv huab cua. Qhov tseeb, fluorinated gases yog cov muaj zog tshaj plaws ntawm tsev cog khoom gases.

Summary – Methane vs Fluorinated Gases

Methane thiab fluorinated gases yog cov pa roj tsev loj. Qhov sib txawv tseem ceeb ntawm methane thiab fluorinated gases yog tias methane yog lub tsev cog khoom roj uas tuaj yeem tsim tau los yog tsim ib txwm muaj, qhov fluorinated gases yog tib neeg tsim tsev cog khoom gases.
