Izisefo ze-molecular ze-Zeolite zibalulekile-enqubweni yokuhlanza yomkhakha wokuhlukanisa umoya we-cryogenic. Ukusakazwa komoya kufanele kudlule kumbhede wesisefo samangqamuzana ngaphambi kokungena engxenyeni enkulu yokuhlukanisa umoya, ukuze kukhishwe ukungcola okungase kuphazamise inqubo ye-cryogenic noma kuthinte ikhwalithi yomkhiqizo.
Iyini I-Cryogenic Air Separation Technology?
Ubuchwepheshe bokuhlukaniswa komoya be-Cryogenic busekelwe ekwehlukeni kwamaphoyinti abilayo wamagesi ahlanganisiwe, kuqala kupholisa umoya ekushiseni okuphansi kakhulu (okungaphansi kwendawo yokubilisa yengxenye ngayinye yegesi), ngokuvamile ngaphansi kwe- -180℃, bese usebenzisa umehluko wamaphuzu abilayo ukuze ukhiphe futhi uhlukanise amagesi.
Ubuchwepheshe bokuhlukaniswa komoya be-Cryogenic busetshenziswa kabanzi ensimbi, amakhemikhali, e-electronics, ezokwelapha, e-aerospace nakweminye imikhakha. Kuyindlela eyinhloko yokuhlukaniswa kwegesi yezimboni, futhi okwamanje iyindlela evuthiwe kakhulu futhi ephumelelayo yokukhiqiza umoya-mpilo wezimboni, i-nitrogen, i-argon namagesi angavamile.
I-Cryogenic Distillation Air Separation Process
Inqubo yokuhlukanisa umoya we-Cryogenic distillation ngokuvamile ihlanganisa izinyathelo eziyisithupha ezilandelayo:
Ukucindezelwa komoya: Cindezela umoya ngezigaba eziningi zama-compressor, ukuze unikeze ingcindezi edingekayo yokupholisa komoya kanye nokuhlukana okulandelayo. Ibanga lokucindezela lingaba ngu-0.5Mpa~0.8Mpa (idivayisi evamile yokucindezela), noma 3Mpa~6Mpa (idivayisi yomfutho ophezulu).
Ngaphambi-Ukupholisa: Yehlisa izinga lokushisa lomoya liye endaweni yokuncibilika ngesibandisi (ngokuvamile amanzi okupholisa noma isiqandisi), cishe amadigri angu-5 kuya ku-10 degree, ukwehlisa isidingo samandla sokuhlukaniswa komoya okune-cryogenic.
{0}}Ukuhlanzwa kwangaphambili: Sebenzisa imibhoshongo ye-adsorption (elayishwe ngezisefo zamamolekyuli, i-alumina evuliwe nezinye izithasiselo) ukuze ususe ukungcola okunjengomswakama, i-carbon dioxide nama-hydrocarbons, ukuvimbela{1}}ukubanda okuphansi{1}}kokuqanda okuphansi nokuvala okokusebenza, ukuqinisekisa ukuphepha kwenqubo ye-cryogenic.
Ukupholisa okujulile: Umoya ohlanzekile ushintshanisa ukushisa nokugeleza komoya obandayo, kancane kancane uphole uze ufike ezingeni lokushisa eliwuketshezi, cishe -170℃kuya ku-180 degree, kanti enye igesi esemoyeni iyancibilika.
Ukuhlukaniswa kwe-distillation: Ikholomu yomfutho ophezulu wegazi ihlukanisa umoya-mpilo-noketshezi olucebile kanye noketshezi lwe-nitrogen{1}}elicebile. -i-oksijini ehlanzekile ephezulu ne-nitrogen kutholakala kukholomu yengcindezi ephansi ngemva kokukhishwa kwe-distillation okwengeziwe. Futhi igesi ye-argon iholwa iphuma phakathi nekholomu yengcindezi ephansi.
Gas extraction and storage: Oxygen, nitrogen and argon are reheated to gas and and then output. Some are liquefied for storage, such as liquid oxygen and liquid nitrogen. However, high purity oxygen (>99.5%), nitrogen (>99.9%), and argon (>99.9%) ayatholakala uma eceliwe.
Izisefo ze-Molecular For Cryogenic Air Separation
I-13X-I-APG Zeolite Molecular Sieve: Ithuthukiswe ngokukhethekile imboni yokuhlukanisa umoya i-air cryogenic, isebenza kunoma yimuphi usayizi we-air cryo{2}}imishini yokuhlukanisa{3}}X{4}}I-APG inamandla okukhetha anamandla okukhetha amanzi ne-carbon dioxide.
I-13X-I-HP Zeolite Molecular Sieve: Inokusebenza kokuhlukaniswa kwe-oxygen ne-nitrogen eyanele kanye nezinga elanele lokukhiqiza umoya-mpilo, elisetshenziselwa kakhulu amayunithi akhiqiza umoya-mpilo ukuze kusetshenziswe ukuhlukaniswa komoyampilo ne-nitrogen, okwenza ukunothisa komoyampilo wezimboni nezokwelapha.
I-13X-APG-III Zeolite Molecular Sieve: Iwuhlobo oluthuthukisiwe lwe-13X-APG. Ukusebenza kwe-adsorption ye-zeolite 13X-APG-III iphakeme ngo-60%~70% kunaleyo ye-13X-APG. Ngisho nasezimeni eziphansi ze-carbon dioxide, umthamo we-adsorption we-13X-APG-III usasebenza kahle.
I-13X-APG-V Zeolite Molecular Sieve: Ukusebenza kwe-adsorption kwe-13X-APG-V kungaphezu kokuphindwe kabili kwalokho kwe-13X-APG, futhi ngaphezu kwezikhathi ezingu-1.4 I-13X-APG-III. 13X-I-APG-Isefa ye-V molecular iyinto ehamba phambili embonini yokuhlukanisa umoya we-cryogenic, futhi izinkomba zayo zokusebenza ziphakeme kakhulu kunezandulelayo.
