Tsanangudzo uye Maitiro Ekuchena kweKuchena KwakanyanyaMethane

Kuchena kwakanyanyamethanezvinoreva gasi remethane rine kuchena kwakanyanya. Kazhinji, methane ine kuchena kwe99.99% kana kupfuura inogona kunzi yakachena zvakanyanyamethaneMune mamwe mashandisirwo akaomarara, akadai seindasitiri yezvemagetsi, zvinodiwa pakuchena zvinogona kusvika 99.999% kana kutopfuura. Kuchena uku kwakanyanya kunowanikwa kuburikidza nehunyanzvi hwakaoma hwekuchenesa gasi uye kupatsanurana kubvisa tsvina dzakadai sehunyoro, kabhoni dhayiokisaidhi, kabhoni monoxide, hydrogen, nezvimwe zvikamu zvegasi.

Nzvimbo dzekushandisa methane ine kuchena kwakanyanya

Muindasitiri yezvemagetsi,methane yakachena kwazvoinoshandiswa segasi rinocheka uye sechigadzirwa chekugadzira makemikari emhepo (CVD) mukugadzira semiconductor. Semuenzaniso, mukugadzira plasma, methane inosanganiswa nemamwe magasi kuti icheke zvinhu zve semiconductor nemazvo, zvichiita mapatani madiki edunhu. MuCVD,methaneinopa nzvimbo yekuburitsa kabhoni pakurima mafirimu matete akagadzirwa nekabhoni, akadai semafirimu esilicon carbide, ayo anoita basa rakakosha mukuvandudza mashandiro uye kugadzikana kwemidziyo yesemiconductor.

Zvishandiso zveMakemikari:Methane yakachena kwazvochinhu chakakosha pakugadzira makemikari akawanda anowedzera kukosha. Semuenzaniso, inogona kusangana ne chlorine kugadzira makemikari e chloromethane akadai se chloroform, dichloromethane, trichloromethane, uye carbon tetrachloride. Chloromethane chinhu chakakosha pakugadzira makemikari e organosilicon, dichloromethane ne trichloromethane zvinowanzo shandiswa se solvents, uye carbon tetrachloride yaimbo shandiswa semushonga wekudzimisa moto, asi kushandiswa kwayo ikozvino kwava kushoma nekuda kwemhedzisiro yayo ye ozone-depleting. Uyezve,methaneinogona kushandurwa kuita syngas (musanganiswa wecarbon monoxide nehydrogen) kuburikidza nekuchinja mashandiro, uye syngas chinhu chakakosha pakugadzira methanol, synthetic ammonia, nezvimwe zvigadzirwa zvakawanda zvemakemikari.

Muchikamu chesimba: Kunyange zvazvo methane yakajairika (gasi rechisikigo) iriyo simba guru,methane yakachena kwazvoine basawo mune mamwe mashandisirwo esimba rakasiyana. Semuenzaniso, mumasero emafuta, methane ine purity yakawanda inogona kushandiswa semafuta, ichigadziriswa kuti igadzire hydrogen, iyo inopa simba kumasero emafuta. Zvichienzaniswa nemafuta ekare, masero emafuta anoshandisa methane ine purity yakawanda anowana simba rakawanda uye anoderedza kusvibiswa kwemhepo.

Kugadzirira magasi akajairika:Methane yakachena kwazvoinogona kushandiswa segasi rakajairika rekuongorora magasi. Semuenzaniso, mu gasi chromatograph, uchishandisamethane yakachena kwazvoGasi rakajairika rine huwandu hunozivikanwa rinogona kugadzirisa kunzwisisika kwekuona kwechishandiso uye kururama kwacho, zvichiita kuti pave nemhedzisiro chaiyo uye yakavimbika yekuongorora mamwe magasi.
