Ngokuthuthuka okusheshayo kwamakhemikhali, amandla, izimboni zezokwelapha nezinye, isidingo samagesi ezimboni ezihlanzekile (njenge-oxygen, i-nitrogen, i-argon) iyaqhubeka ikhula.Ubuchwepheshe be-Cryogenic Air Separation, njengendlela evuthiwe kakhulu yokuhlukanisa igesi ngezinga elikhulu, isibe yisixazululo esiyinhloko semboni ngokusebenza kwayo okuphezulu nokuzinza. Lesi sihloko sizohlaziya izimiso zayo zobuchwepheshe, umehluko ezimeni ezihlukene zohlelo lokusebenza kanye nezidingo zokumisa eziyisisekelo.
Uma kuqhathaniswa nemishini yokuhlukanisa umoya wegesi, okokusebenza kokuhlukanisa umoya owuketshezi kudinga umthamo owengeziwe wokupholisa. Ngokusho kokukhishwa okuhlukile kwemishini yokuhlukanisa umoya owuketshezi, sisebenzisa izinqubo ezahlukahlukene zomjikelezo wesiqandisi:isiqandisi sokunwetshwa kwe-booster turbine, isiqandisi se-precooler esinezinga lokushisa eliphansi, i-circulation compressor ephezulu kanye ne-low pressure expander expansion isiqandisi, njll., ukufeza umgomo wokunciphisa ukusetshenziswa kwamandla ngokusebenzisa izindlela ezihlukahlukene. Uhlelo lokulawula luyamukelaIsistimu yokulawula ye-DCS noma ye-PLC, futhi isiza amathuluzi asensimini ukwenza yonke isethi yezisetshenziswa zibe lula, zizinze futhi zithembeke.
Izici zobuchwepheshe: Ukuphumelela kwezobuchwepheshe kwe-cryogenic distillation
Ubuchwepheshe bokuhlukaniswa komoya obumanzi obubandayo bucindezela futhi bupholise umoya emazingeni okushisa aphansi kakhulu (ngaphansi kuka-196°C) futhi busebenzisa umehluko wamaphoyinti abilayo engxenye ngayinye ukuze kuzuzwe ukuhlukaniswa. Izinzuzo eziyinhloko zihlanganisa:
- Okuphumayo kokuhlanzeka okuphezulu:Ingakhiqiza i-99.999% i-oxygen ehlanzekile, i-nitrogen ehlanzekile kanye ne-argon ephezulu yokuhlanzeka ukuhlangabezana nezidingo eziphezulu ezifana nama-semiconductors kanye nokwelashwa kwezokwelapha.
- Amandla okukhiqiza amakhulu:Ukukhishwa kwansuku zonke kweyunithi eyodwa kungafinyelela izinkulungwane zamathani, afanele izimboni ezinzima njengemboni yensimbi namakhemikhali.
- Ukusebenza kahle kwamandla:Imishini yesimanje yokuhlukanisa umoya ihlanganisa ama-compressor asebenza kahle kakhulu, izinwebezi kanye nezishintshisi zokushisa, inciphisa ukusetshenziswa kwamandla ngaphezu kwama-30%.
Umehluko wohlelo lokusebenza: Isidingo semboni siqhuba ukuhlukaniswa kobuchwepheshe
Izimboni ezihlukene zinezidingo ezihlukene zezinhlelo zokuhlukanisa umoya obandayo, ezihlukaniswe ikakhulukazi lezi zigaba ezilandelayo:
Uhlobo lwezimboni lwendabuko
- Izindawo zokufaka isicelo:i-metallurgy, i-petrochemicals.
- Izici:Gxila kumoya-mpilo ogeleza kakhulu (njengosizo lokwenza insimbi evuthayo) noma i-nitrogen (njengegesi evikela amakhemikhali), efakwe amathangi amakhulu okugcina kanye nezinhlelo zokuthutha zamapayipi.
Electronic grade high ukuhlanzeka uhlobo
- Izindawo zokufaka isicelo:ama-semiconductors, ama-photovoltaics.
- Izici:I-ultra-pure gas (ukungcola ≤ 0.1ppm) iyadingeka, futhi imibhoshongo yokukhishwa kwe-distillation enezigaba eziningi kanye namamojula okuhlunga ngokunemba ayalungiswa.
Uhlobo lokunakekelwa kwezempilo
- Izindawo zokufaka isicelo:izibhedlela, i-biopharmaceuticals.
- Izici:ukugcizelelwa kokuphepha kanye nokuhlinzekwa ngokushesha, okuvamise ukuhlonyiswa ngamathangi okugcina umoya-mpilo owuketshezi kanye nezinhlelo zokuhwamuka.
Uhlobo olusha olusekela amandla
- Izindawo zokufaka isicelo:amandla e-hydrogen, ukuthunjwa kwe-carbon.
- Izici:i-krypton ehlanganisiwe, i-xenon kanye neminye imisebenzi yokukhipha igesi eyivelakancane, eguqulelwe kuchungechunge lwemboni yamandla aluhlaza.
Ukucushwa okuyisisekelo: imojuli eyinhloko yesistimu yokuhlukanisa umoya
Isethi ephelele yemishini yokuhlukanisa umoya owuketshezi obandayo ngokuvamile ihlanganisa lezi zingxenye ezibalulekile ezilandelayo:
1. Uhlelo lokucindezelwa komoya
I-compressor ye-centrifugal enezigaba eziningi, enikeza ingcindezi edingekayo ukuze kuhlukaniswe (0.5-1.0MPa).
2. Iyunithi yokupholisa kuqala kanye nokuhlanza
I-adsorber ye-sieve ye-molecular isusa ukungcola okunjengomswakama kanye ne-CO₂.
3. Imishini ye-cryogenic eyinhloko
- - Isishintshi sokushisa esiyinhloko: ukushintshanisa ukushisa phakathi komoya negesi yomkhiqizo.
- - Umbhoshongo we-distillation wezigaba ezimbili: ukuhlukaniswa kwe-oxygen / i-nitrogen embhoshongweni ophansi, ukuhlanzeka okuqhubekayo embhoshongweni ongaphezulu.
4. Isiqandisi sokunweba
Inikeza amandla okupholisa okuqhubekayo ukuze kugcinwe indawo enezinga lokushisa eliphansi.
5. Isitoreji kanye nesistimu ye-vaporization
Amathangi okugcina i-nitrogen ewuketshezi, amaphampu e-cryogenic kanye nama-vaporizer.
Amathrendi wesikhathi esizayo: ubuhlakani kanye ne-carbonization ephansi
Ubuchwepheshe bokuhlukanisa umoya womhlaba wonke benza impumelelo ngezindlela ezimbili:
- Ubuhlakani:Lungiselela ukusetshenziswa kwamandla ngama-algorithms e-AI futhi uqaphe ukuhlanzeka kwegesi ngesikhathi sangempela.
- Okuluhlaza:Sebenzisa amandla avuselelekayo ukushayela amayunithi womminyanisa ukuze unciphise indawo ye-carbon footprint.
Nganoma yiziphi izidingo ze-oxygen/nitrogen/argon, sicela usithinte:
