Tanthauzo ndi Miyezo ya Chiyero cha Ukhondo WapamwambaMethane

Kuyera kwambirimethaneamatanthauza mpweya wa methane wokhala ndi chiyero chapamwamba. Kawirikawiri, methane yokhala ndi chiyero cha 99.99% kapena kupitirira apo imatha kuonedwa ngati yoyera kwambirimethane. Mu ntchito zina zovuta kwambiri, monga makampani a zamagetsi, zofunikira pa kuyera zimatha kufika 99.999% kapena kupitirira apo. Kuyera kwakukulu kumeneku kumachitika kudzera muukadaulo wovuta woyeretsa mpweya ndi kulekanitsa kuti muchotse zonyansa monga chinyezi, carbon dioxide, carbon monoxide, hydrogen, ndi zinthu zina za gasi.

Malo ogwiritsira ntchito methane yoyera kwambiri

Mu makampani a zamagetsi,methane yoyera kwambiriimagwiritsidwa ntchito ngati mpweya wothira ndi zinthu zopangira mpweya wa mankhwala (CVD) popanga ma semiconductor. Mwachitsanzo, pothira plasma, methane imasakanizidwa ndi mpweya wina kuti ithyole bwino zinthu za semiconductor, ndikupanga mawonekedwe ang'onoang'ono a circuit. Mu CVD,methaneimapereka gwero la kaboni polima mafilimu opyapyala okhala ndi kaboni, monga mafilimu a silicon carbide, omwe amagwira ntchito yofunika kwambiri pakukweza magwiridwe antchito ndi kukhazikika kwa zida za semiconductor.

Zipangizo Zamankhwala:Methane yoyera kwambirindi chinthu chofunikira kwambiri popanga mankhwala ambiri owonjezera. Mwachitsanzo, imatha kuchitapo kanthu ndi chlorine kuti ipange mankhwala a chloromethane monga chloroform, dichloromethane, trichloromethane, ndi carbon tetrachloride. Chloromethane ndi chinthu chopangira mankhwala a organosilicon, dichloromethane ndi trichloromethane nthawi zambiri amagwiritsidwa ntchito ngati zosungunulira, ndipo carbon tetrachloride kale inkagwiritsidwa ntchito ngati chozimitsira moto, koma kugwiritsidwa ntchito kwake tsopano kuli kochepa chifukwa cha zotsatira zake zowononga ozone. Komanso,methaneingasinthidwe kukhala syngas (chisakanizo cha carbon monoxide ndi hydrogen) kudzera mu kusintha kwa zinthu, ndipo syngas ndi chinthu chofunikira kwambiri popanga methanol, ammonia yopangidwa, ndi mankhwala ena ambiri.

Mu gawo la mphamvu: Ngakhale kuti methane wamba (mpweya wachilengedwe) ndiye gwero lalikulu la mphamvu,methane yoyera kwambiriImagwiranso ntchito pa ntchito zina zapadera zamagetsi. Mwachitsanzo, m'maselo amafuta, methane yoyera kwambiri ingagwiritsidwe ntchito ngati mafuta, ikusinthidwa kuti ipange haidrojeni, yomwe imapatsa mphamvu maselo amafuta. Poyerekeza ndi mafuta akale, maselo amafuta omwe amagwiritsa ntchito methane yoyera kwambiri amapeza mphamvu zambiri komanso mpweya woipa wotsika.

Kukonzekera mpweya wokhazikika:Methane yoyera kwambiriingagwiritsidwe ntchito ngati mpweya wamba woyezera zida zowunikira mpweya. Mwachitsanzo, mu chromatograph ya mpweya, pogwiritsa ntchitomethane yoyera kwambiriMpweya wokhazikika wodziwika bwino ukhoza kuwerengera kulondola kwa chipangizocho, kuonetsetsa kuti zotsatira zolondola komanso zodalirika za mpweya wina zikupezeka.
