Ubuchwepheshe bokuhlukanisa umoya we-cryogenic bungenye yezindlela ezibalulekile zokukhiqiza i-nitrogen ne-oxygen ehlanzekile kakhulu embonini yanamuhla. Lobu buchwepheshe busetshenziswa kabanzi ezimbonini ezahlukahlukene ezifana ne-metallurgy, ubunjiniyela bamakhemikhali, kanye nezokwelapha. Lesi sihloko sizohlola ngokujulile ukuthi ukuhlukaniswa komoya we-cryogenic kukhiqiza kanjani i-nitrogen ne-oxygen ehlanzekile kakhulu, kanye nezinyathelo ezibalulekile kanye nemishini ehilelekile kule nqubo.

1. Isimiso esiyisisekelo sokuhlukaniswa komoya okhanyayo

Ukuhlukaniswa komoya okubangelwa yi-cryogenic kuyinqubo ehlukanisa izingxenye eziyinhloko zomoya ngokwehlisa izinga lokushisa. Umoya ikakhulukazi uqukethe i-nitrogen, i-oxygen, kanye nenani elincane le-argon. Ngokucindezela nokupholisa umoya ube yizinga lokushisa eliphansi kakhulu, umoya uyancibilika, bese kusetshenziswa amaphuzu abilayo ahlukene egesi ngayinye ukuze kuhlukaniswe i-nitrogen ne-oxygen. Iphuzu lokubilisa le-nitrogen lingu-195.8℃, kanti elomoya-mpilo lingu-183℃, ngakho-ke zingahlanzwa ngokwehlukana ngokusebenzisa ukuncibilika okuhleliwe.

2. Isigaba sangaphambi kokwelashwa: Ukuhlanzwa komoya

Enqubweni yokuhlukanisa umoya we-cryogenic, ukwelashwa komoya kusengaphambili kuyisinyathelo sokuqala esibalulekile. Umoya uqukethe ukungcola okufana nothuli, i-carbon dioxide, kanye nomswakama, okuzoqandisa endaweni ephansi yokushisa, okubangela ukuvaleka kwemishini. Ngakho-ke, umoya uqala ngokuhlungwa, ukucindezelwa, kanye nezinyathelo zokomisa ukuze kususwe ukungcola kanye nomswakama. Ngokuvamile, ama-dryer kanye nama-molecular sieve adsorbers yimishini ebalulekile esetshenziselwa ukususa ukungcola emoyeni, ukuqinisekisa ukuzinza nokusebenza kahle kwenqubo elandelayo yokuhlukanisa i-cryogenic.

3. Ukucindezelwa komoya kanye nokupholisa

Umoya ohlanziwe udinga ukucindezelwa, ngokuvamile ngama-compressor amaningi ukuze kwandiswe ingcindezi yomoya ibe ngama-megapascal angu-5-6. Umoya ocindezelwe ube usupholiswa ngama-heat exchanger anegesi ebuyayo ekushiseni okuphansi, kancane kancane kunciphisa izinga lokushisa ukuze lisondele endaweni yokuncibilika. Kule nqubo, ama-heat exchanger adlala indima ebalulekile, njengoba enganciphisa ngempumelelo ukusetshenziswa kwamandla futhi athuthukise ukusebenza kahle kokupholisa, aqinisekise ukuthi umoya ungancibilika ngaphansi kwezimo zokushisa okuphansi, okuhlinzeka ngezimo zokuhlukaniswa kwe-distillation okulandelayo.

4. Ukuncibilikisa umoya kanye nokuncibilikisa

Embhoshongweni wokuhlukanisa i-cryogenic, umoya ocindezelwe nopholile upholiswa kakhulu ube sesimweni soketshezi. Umoya oketshezi uthunyelwa embhoshongweni wokuhluza ukuze uhlukaniswe. Umbhoshongo wokuhluza uhlukaniswe izingxenye ezimbili: umbhoshongo wokucindezela okuphezulu nombhoshongo wokucindezela okuphansi. Embhoshongweni wokucindezela okuphezulu, umoya uhlukaniswa ube yi-oksijini engahluziwe kanye ne-nitrogen engahluziwe, bese kuthi i-oksijini engahluziwe kanye ne-nitrogen engahluziwe kuhluzwe kabanzi embhoshongweni wokucindezela okuphansi ukuze kutholakale i-oksijini engahluziwe ephezulu kanye ne-nitrogen. Ukuhlukaniswa kwe-nitrogen ne-oxygen kusebenzisa kakhulu izakhiwo zazo zomzimba ezahlukene zamaphuzu abilayo, ngakho-ke ukuhlukaniswa okuphumelelayo kungatholakala embhoshongweni wokuhluza.

5. Inqubo yokuhlanzwa

I-oxygen ne-nitrogen ezihlukaniswe embhoshongweni wokuhluza kusenenani elincane lokungcola, ngakho-ke zidinga ukuhlanzwa kabanzi ukuze kuhlangatshezwane nezindinganiso zezimboni nezezokwelapha. Ubumsulwa be-nitrogen bungathuthukiswa ngokusebenzisa ama-catalyst e-hydrogen deoxygenation, kuyilapho ubumsulwa be-oxygen bungatholakala ngezinqubo zokuhluza kabusha. Ukuze kuthuthukiswe ubumsulwa begesi yomkhiqizo, imishini efana nezihlanzi ze-nitrogen kanye nezihlanzi ze-oxygen ngokuvamile isetshenziswa, ekugcineni kutholakale imikhiqizo ye-oxygen ne-nitrogen ehlanzekile kakhulu.

6. Ukusetshenziswa kwe-nitrogen ne-oxygen

I-nitrogen ehlanzekile kakhulu kanye nomoya-mpilo okhiqizwa ubuchwepheshe bokuhlukanisa umoya we-cryogenic kusetshenziswa kabanzi ezimbonini eziningi. I-nitrogen ehlanzekile kakhulu isetshenziswa embonini yamakhemikhali njengegesi evikelayo kanye negesi yokuthwala, embonini yokudla yokugcina nokupakisha, kanti umoya-mpilo usetshenziswa kabanzi ezimbonini zezokwelapha kanye nezokuxhuma. Embonini yensimbi, umoya-mpilo usetshenziswa futhi ukuthuthukisa ukusebenza kahle kokushisa nokunciphisa ukukhishwa kwekhabhoni. Kulezi zinhlelo zokusebenza, ubumsulwa begesi buyisihluthulelo sokunquma ukusebenza kwayo, kanti ubuchwepheshe bokuhlukanisa umoya we-cryogenic buye baqashelwa kabanzi ngokuhlukaniswa kwayo okusebenzayo kanye nokukhishwa kwayo okuhlanzekile kakhulu.

7. Izinzuzo nezinselele zobuchwepheshe bokuhlukanisa umoya obusebenzisa i-cryogenic

Ubuchwepheshe bokuhlukanisa umoya we-cryogenic buyathandwa emkhakheni wezimboni ngenxa yobumsulwa bawo obuphezulu kanye nokusebenza kahle okuphezulu. Kodwa-ke, lobu buchwepheshe bubhekene nezinselele ezithile, njengokusetshenziswa kwamandla aphezulu kanye nezindleko zokulungisa imishini ephezulu. Ukuze kuncishiswe ukusetshenziswa kwamandla, imishini yokuhlukanisa umoya we-cryogenic yesimanje ivame ukuza nezinhlelo ezithuthukisiwe zokonga amandla, njengamadivayisi okubuyisa ukushisa kanye nezinhlelo zokupholisa zokucindezela ezisezingeni eliningi. Ngaphezu kwalokho, ukusetshenziswa kobuchwepheshe bokulawula okuzenzakalelayo kuthuthukise kakhulu ukusebenza kahle kanye nokuphepha kwamayunithi okuhlukanisa umoya we-cryogenic ejulile. Ngokusebenzisa ubuchwepheshe kanye nokuthuthukiswa kwemishini, ukusebenza kahle kwamandla kanye nokuzinza kwezinhlelo zokuhlukanisa umoya we-cryogenic ejulile kuye kwathuthukiswa njalo, okuthuthukisa ukusetshenziswa kwazo ezimbonini ezahlukene.

Ukuhlukaniswa komoya okujulile okune-cryogenic okwamanje kungenye yezindlela eziphumelela kakhulu zokukhiqiza i-nitrogen ne-oxygen ehlanzekile kakhulu. Kuhlukanisa futhi kuhlanze i-oxygen ne-nitrogen emoyeni ngempumelelo ngezinyathelo eziningi ezifana nokwelashwa komoya ngaphambi kokwelashwa, ukucindezela, ukupholisa, uketshezi, kanye nokuhluzwa. Nakuba inqubo yokuhlukaniswa komoya okujulile okune-cryogenic isebenzisa amandla amaningi kanye nemishini eyinkimbinkimbi, umphumela wayo wokuhlukanisa ophumelelayo kanye nomkhiqizo womkhiqizo ohlanzekile kakhulu kwenza lobu buchwepheshe bubaluleke kakhulu ezimbonini eziningi.
