Incazelo kanye Namazinga Obumsulwa Okuhlanzeka OkuphezuluI-Methane

Ukuhlanzeka okuphezului-methaneibhekisela kugesi ye-methane enobumsulwa obuphakeme. Ngokuvamile, i-methane enobumsulwa obungu-99.99% noma ngaphezulu ingabhekwa njengokuhlanzeka okuphezului-methane. Kwezinye izinhlelo zokusebenza eziqinile, njengemboni yezogesi, izidingo zokuhlanzeka zingafinyelela ku-99.999% noma ngaphezulu. Lokhu kuhlanzeka okuphezulu kutholakala ngobuchwepheshe obuyinkimbinkimbi bokuhlanzwa kwegesi nokuhlukanisa ukususa ukungcola okunjengomswakama, i-carbon dioxide, i-carbon monoxide, i-hydrogen, nezinye izingxenye zegesi.

Izindawo zokufaka isicelo ze-methane ephezulu yokuhlanzeka

Embonini yezogesi,high-purity methaneisetshenziswa njenge-etching gas kanye ne-raw material ye-chemical vapor deposition (CVD) ekwenzeni i-semiconductor. Isibonelo, ku-plasma etching, i-methane ixutshwa namanye amagesi ukuze kuqoshwe ngokunembile izinto ze-semiconductor, yakhe amaphethini esekethe amancane. Ku-CVD,i-methaneihlinzeka ngomthombo wekhabhoni wokukhulisa amafilimu amancanyana asuselwa kukhabhoni, njengamafilimu e-silicon carbide, adlala indima ebalulekile ekuthuthukiseni ukusebenza nokuzinza kwamadivayisi we-semiconductor.

I-Chemical Raw Materials:I-methane ehlanzekile ephezuluiyimpahla ebalulekile yokusetshenziswa kwamakhemikhali amaningi anenani eliphezulu. Isibonelo, ingasabela nge-chlorine ukukhiqiza izinhlanganisela ze-chloromethane njenge-chloroform, i-dichloromethane, i-trichloromethane, ne-carbon tetrachloride. I-Chloromethane iyimpahla eluhlaza yokukhiqizwa kwezinhlanganisela ze-organosilicon, i-dichloromethane ne-trichloromethane zivame ukusetshenziswa njengezincibilikisi, futhi i-carbon tetrachloride yake yasetshenziswa njenge-ejenti yokucisha umlilo, kodwa ukusetshenziswa kwayo manje kunqunyelwe ngokuqinile ngenxa yemiphumela yayo yokuqeda i-ozone. Ngaphezu kwalokho,i-methaneingaguqulwa ibe yi-syngas (ingxube ye-carbon monoxide ne-hydrogen) ngokushintsha ukusabela, futhi i-syngas iwumthombo obalulekile wokukhiqiza i-methanol, i-synthetic ammonia, neminye imikhiqizo eminingi yamakhemikhali.

Emkhakheni wezamandla: Nakuba i-methane evamile (igesi yemvelo) iwumthombo wamandla oyinhloko,high-purity methanefuthi idlala indima kwezinye izinhlelo zokusebenza zamandla ezikhethekile. Isibonelo, kuma-fuel cell, i-methane ehlanzekile kakhulu ingasetshenziswa njengophethiloli, ehlelwa kabusha ukuze kukhiqizwe i-hydrogen, enika amandla i-fuel cell. Uma kuqhathaniswa nezibaseli zendabuko, amangqamuzana kaphethiloli asebenzisa i-methane ehlanzeke kakhulu afinyelela ukusebenza kahle kwamandla kanye nokukhipha ukungcola okuphansi.

Ukulungiswa kwamagesi ajwayelekile:I-methane ehlanzekile ephezuluingasetshenziswa njengegesi ejwayelekile yokulinganiswa kwamathuluzi okuhlaziya igesi. Isibonelo, ku-chromatograph yegesi, usebenzisahigh-purity methaneigesi ejwayelekile yokugxilisa ingqondo okwaziwayo ingalinganisa ukuzwela kokutholwa kwensimbi nokunemba, iqinisekise imiphumela yokuhlaziya enembile nethembekile kwamanye amagesi.
