Incazelo kanye nezindinganiso zobumsulwa bobumsulwa obuphezuluI-Methane

Ubumsulwa obuphezului-methaneibhekisela kugesi ye-methane enokuhlanzeka okuphezulu. Ngokuvamile, i-methane enokuhlanzeka okungu-99.99% noma ngaphezulu ingabhekwa njengokuhlanzeka okuphezului-methaneKwezinye izinhlelo zokusebenza eziqinile, njengemboni ye-elekthronikhi, izidingo zobumsulwa zingafinyelela ku-99.999% noma ngaphezulu. Lokhu kuhlanzeka okuphezulu kutholakala ngokusebenzisa ubuchwepheshe obuyinkimbinkimbi bokuhlanzwa kwegesi nokuhlukanisa ukuze kususwe ukungcola okufana nomswakama, i-carbon dioxide, i-carbon monoxide, i-hydrogen, nezinye izingxenye zegesi.

Izindawo zokusetshenziswa kwe-methane ehlanzekile kakhulu

Embonini ye-elekthronikhi,i-methane ehlanzekile kakhuluisetshenziswa njengegesi yokuqopha kanye nezinto zokusetshenziswa zokufaka umphunga wamakhemikhali (i-CVD) ekukhiqizweni kwe-semiconductor. Isibonelo, ekuqopheni kwe-plasma, i-methane ixutshwa namanye amagesi ukuze iqophe ngokunembile izinto ze-semiconductor, kwakhiwe amaphethini amancane wesekethe. Ku-CVD,i-methaneinikeza umthombo wekhabhoni wokutshala amafilimu amancane asekelwe kukhabhoni, njengamafilimu e-silicon carbide, adlala indima ebalulekile ekuthuthukiseni ukusebenza kanye nokuzinza kwamadivayisi e-semiconductor.

Izinto Zokusetshenziswa Zamakhemikhali:I-methane emsulwa kakhuluiyinto eluhlaza ebalulekile yokwenziwa kwamakhemikhali amaningi anenani eliphezulu. Isibonelo, ingasabela ne-chlorine ukukhiqiza amakhemikhali e-chloromethane njenge-chloroform, i-dichloromethane, i-trichloromethane, kanye ne-carbon tetrachloride. I-Chloromethane iyinto eluhlaza yokukhiqiza amakhemikhali e-organosilicon, i-dichloromethane kanye ne-trichloromethane zivame ukusetshenziswa njengezinyibilikisi, kanti i-carbon tetrachloride yake yasetshenziswa njenge-ejenti yokucisha umlilo, kodwa ukusetshenziswa kwayo manje sekulinganiselwe ngenxa yemiphumela yayo yokuqeda i-ozone. Ngaphezu kwalokho,i-methaneingaguqulwa ibe yi-syngas (ingxube ye-carbon monoxide ne-hydrogen) ngokusebenzisa ukusabela okuguqukayo, futhi i-syngas iyinto eluhlaza eyisisekelo yokukhiqizwa kwe-methanol, i-ammonia yokwenziwa, kanye neminye imikhiqizo eminingi yamakhemikhali.

Emkhakheni wamandla: Nakuba i-methane evamile (igesi yemvelo) ingumthombo wamandla oyinhloko,i-methane ehlanzekile kakhulufuthi idlala indima kwezinye izinhlelo zokusebenza zamandla ezikhethekile. Isibonelo, kumaseli kaphethiloli, i-methane ehlanzekile kakhulu ingasetshenziswa njengophethiloli, iguqulwa ukuze ikhiqize i-hydrogen, enika amandla iseli kaphethiloli. Uma kuqhathaniswa namafutha endabuko, amaseli kaphethiloli asebenzisa i-methane ehlanzekile kakhulu athola ukusebenza kahle kwamandla okuphezulu kanye nokukhishwa okuphansi kokungcola.

Ukulungiswa kwamagesi ajwayelekile:I-methane emsulwa kakhuluingasetshenziswa njengegesi ejwayelekile yokulinganisa amathuluzi okuhlaziya igesi. Isibonelo, ku-chromatograph yegesi, kusetshenziswai-methane ehlanzekile kakhuluigesi ejwayelekile yokuhlushwa okwaziwayo ingalinganisa ukuzwela kokutholwa kwethuluzi kanye nokunemba kwalo, iqinisekise imiphumela yokuhlaziya enembile nethembekile kwamanye amagesi.
