Ma'anar Ma'anar Tsarkakewa da Tsabtace Tsabtace TsabtaceMethane

High-tsarkimethaneyana nufin iskar methane mai tsafta mai inganci. Gabaɗaya, methane tare da tsaftar 99.99% ko mafi girma ana iya la'akari da babban-tsarkimethane. A wasu ƙarin tsauraran aikace-aikace, kamar masana'antar lantarki, buƙatun tsabta na iya kaiwa 99.999% ko ma sama da haka. Ana samun wannan tsafta mai girma ta hanyar hadaddun tsaftacewar iskar gas da fasahohin rabuwa don kawar da datti kamar danshi, carbon dioxide, carbon monoxide, hydrogen, da sauran abubuwan da suka shafi iskar gas.

Yankunan aikace-aikacen methane mai tsafta

A cikin masana'antar lantarki,high-tsarki methaneana amfani da shi azaman iskar gas da ɗanyen abu don ajiyar tururin sinadarai (CVD) a masana'antar semiconductor. Misali, a cikin etching plasma, methane yana haɗe da sauran iskar gas don daidaita daidaitattun kayan aikin semiconductor, yana samar da ƙananan ƙirar kewaye. A cikin CVD,methaneyana ba da tushen carbon don haɓaka fina-finai na bakin ciki na tushen carbon, kamar fina-finai na silicon carbide, waɗanda ke taka muhimmiyar rawa wajen haɓaka aiki da kwanciyar hankali na na'urorin semiconductor.

Kayayyakin Raw na Chemical:High-tsarki methanewani abu ne mai mahimmanci don haɗar sinadarai masu daraja da yawa. Alal misali, yana iya amsawa da chlorine don samar da mahadi na chloromethane kamar chloroform, dichloromethane, trichloromethane, da carbon tetrachloride. Chloromethane danyen abu ne na samar da mahadi na organosilicon, dichloromethane da trichloromethane galibi ana amfani da su azaman masu kaushi, kuma carbon tetrachloride an taɓa yin amfani da shi azaman wakili na kashe wuta, amma amfani da shi yanzu an iyakance shi sosai saboda tasirinsa na ozone. Bugu da ƙari,methaneana iya canza shi zuwa syngas (cakudadden carbon monoxide da hydrogen) ta hanyar gyara halayen, kuma syngas wani abu ne mai mahimmanci don samar da methanol, ammonia na roba, da sauran samfuran sinadarai masu yawa.

A bangaren makamashi: Yayin da methane gama gari (gas na halitta) shine tushen makamashi na farko,high-tsarki methaneHakanan yana taka rawa a wasu aikace-aikacen makamashi na musamman. Misali, a cikin sel mai, ana iya amfani da methane mai tsafta a matsayin mai, ana yin gyare-gyare don samar da hydrogen, wanda ke ba da iko ga tantanin mai.
