Inkcazo kunye neMigangatho yoBunyulu boBunyulu obuPhezuluIMethane

Ubunyulu obuphezuluimethaneibhekisa kwirhasi yemethane enococeko oluphezulu noko. Ngokuqhelekileyo, i-methane enobunyulu be-99.99% okanye ngaphezulu ingathathwa njengobunyulu obuphezuluimethane. Kwezinye izicelo ezingqongqo ngakumbi, ezifana neshishini le-elektroniki, iimfuno zococeko zinokufikelela kwi-99.999% okanye nangaphezulu. Olu coceko luphezulu lufezekiswa ngokucocwa kwegesi entsonkothileyo kunye nobuchwephesha bokwahlula ukususa ukungcola okunjengokufuma, ikharbhon diokside, icarbon monoxide, ihydrogen, kunye namanye amacandelo egesi.

Iindawo zokusetyenziswa kwe-methane ephezulu yokucoceka

Kwishishini le-elektroniki,i-methane ecocekileyo ephezuluisetyenziswa njengerhasi yokusingela kunye nemathiriyeli ekrwada yokubeka umphunga wekhemikhali (CVD) kwimveliso yesemiconductor. Umzekelo, kwi-plasma etching, i-methane ixutywa nezinye iigesi ukuze ifake ngokuchanekileyo imathiriyeli ye-semiconductor, yenze iipateni ezincinci zesekethe. KwiCVD,imethaneibonelela ngomthombo wekhabhoni wokukhulisa iifilimu ezincinci ezisekelwe kwikhabhoni, ezinjengeefilimu ze-silicon carbide, ezidlala indima ebalulekileyo ekuphuculeni ukusebenza kunye nokuzinza kwezixhobo ze-semiconductor.

IMathiriyeli ekrwada yeMichiza:Imethane ecocekileyo ephezuluyimathiriyeli ekrwada ebalulekileyo yokwenziwa kweekhemikhali ezininzi ezinexabiso eliphezulu. Umzekelo, inokusabela ngeklorine ukuvelisa iikhompawundi zekloromethane ezifana nekloroform, i-dichloromethane, i-trichloromethane, kunye ne-carbon tetrachloride. I-Chloromethane yinto ekrwada yokuveliswa kweekhompawundi ze-organosilicon, i-dichloromethane kunye ne-trichloromethane zidla ngokusetyenziswa njengezinyibilikisi, kwaye i-carbon tetrachloride yayikhe yasetyenziswa njenge-arhente yokucima umlilo, kodwa ukusetyenziswa kwayo ngoku kulinganiselwe ngokungqongqo ngenxa yemiphumo yayo ye-ozone-depleting. Ngaphezu koko,imethaneinokuguqulwa ibe yi-syngas (umxube we-carbon monoxide kunye ne-hydrogen) ngokuguqulwa kweempendulo, kwaye i-syngas sisixhobo esisisiseko sokwenziwa kwe-methanol, i-synthetic ammonia, kunye nezinye iimveliso zemichiza ezininzi.

Kwicandelo lamandla: Ngelixa imethane eqhelekileyo (irhasi yendalo) isesona sixhobo samandla,i-methane ecocekileyo ephezuluikwadlala indima kwizicelo ezithile zamandla ezikhethekileyo. Ngokomzekelo, kwiiseli zamafutha, i-high-purity methane inokusetyenziswa njengamafutha, ihlaziywa ukuvelisa i-hydrogen, eyenza amandla kwiseli yamafutha. Xa kuthelekiswa namafutha efosili yemveli, iiseli zepetroli ezisebenzisa i-methane ecoceke kakhulu zifezekisa ukusebenza kakuhle kwamandla kunye nokukhutshwa kongcoliseko okuphantsi.

Ukulungiswa kweegesi eziqhelekileyo:Imethane ecocekileyo ephezuluingasetyenziselwa njengegesi eqhelekileyo yokulinganisa izixhobo zokuhlalutya igesi. Ngokomzekelo, kwi-chromatograph yegesi, usebenzisai-methane ecocekileyo ephezuluigesi eqhelekileyo yoxinaniso olwaziwayo inokulinganisa uvakalelo lokubona isixhobo kunye nokuchaneka, ukuqinisekisa iziphumo ezichanekileyo nezithembekileyo zokuhlalutya kwezinye iigesi.
