Ubuchwepheshe bokuhlukaniswa komoya obujulile be-cryogenic buyindlela ehlukanisa izingxenye eziyinhloko (i-nitrogen, i-oxygen ne-argon) emoyeni ngokusebenzisa amazinga okushisa aphansi. Isetshenziswa kabanzi ezimbonini ezifana nensimbi, amakhemikhali, ezemithi kanye ne-electronics. Ngokukhula kwesidingo samagesi, ukusetshenziswa kobuchwepheshe bokuhlukaniswa komoya obujulile be-cryogenic nakho kuya ngokuya kusakazeka. Lesi sihloko sizoxoxa ngokugcwele ngenqubo yokukhiqiza yokuhlukaniswa komoya okujulile kwe-cryogenic, okuhlanganisa isimiso sayo sokusebenza, imishini eyinhloko, izinyathelo zokusebenza kanye nokusetshenziswa kwayo ezimbonini ezihlukahlukene.
Uhlolojikelele lweCryogenic Air Separation Technology
Isimiso esiyisisekelo sokuhlukaniswa komoya we-cryogenic ukupholisa umoya emazingeni okushisa aphansi kakhulu (ngokuvamile ngaphansi kuka-150 ° C), ukuze izingxenye ezisemoyeni zihlukaniswe ngokuvumelana namaphuzu azo ahlukene abilayo. Ngokuvamile, i-cryogenic air separation unit isebenzisa umoya njengento eluhlaza futhi ihamba ngezinqubo ezinjengokucindezela, ukupholisa, nokwandisa, ekugcineni ihlukanise i-nitrogen, umoya-mpilo, ne-argon emoyeni. Lobu buchwepheshe bungakhiqiza amagesi ahlanzekile futhi, ngokulawula kahle imingcele yenqubo, ihlangabezane nezidingo eziqinile zekhwalithi yegesi emikhakheni ehlukene yezimboni.
Iyunithi yokuhlukanisa umoya we-cryogenic ihlukaniswe izingxenye ezintathu eziyinhloko: i-air compressor, i-air pre-cooler, nebhokisi elibandayo. I-compressor yomoya isetshenziselwa ukucindezela umoya ekucindezelweni okuphezulu (imvamisa i-5-6 MPa), i-pre-cooler inciphisa izinga lokushisa lomoya ngokupholisa, futhi ibhokisi elibandayo liyingxenye eyinhloko yenqubo yonke yokuhlukanisa umoya we-cryogenic, kuhlanganise nombhoshongo wokuhlukanisa, osetshenziselwa ukufeza ukuhlukaniswa kwegesi.
Ukucindezelwa komoya nokupholisa
Ukucindezelwa komoya kuyisinyathelo sokuqala sokuhlukaniswa komoya we-cryogenic, ikakhulukazi kuhloswe ukucindezela umoya emoyeni ukuze ube nomfutho ophakeme (ngokuvamile u-5-6 MPa). Ngemuva kokuthi umoya ungene ohlelweni nge-compressor, izinga lokushisa layo lizokwanda kakhulu ngenxa yenqubo yokucindezela. Ngakho-ke, uchungechunge lwezinyathelo zokupholisa kufanele lwenziwe ukuze kuncishiswe izinga lokushisa lomoya ocindezelwe. Izindlela zokupholisa ezivamile zihlanganisa ukupholisa kwamanzi nokupholisa umoya, futhi umphumela omuhle wokupholisa ungaqinisekisa ukuthi umoya ocindezelwe awubangeli umthwalo ongadingekile emishinini ngesikhathi sokucubungula okulandelayo.
Ngemuva kokuthi umoya usupholile kuqala, ungena esigabeni esilandelayo sokupholisa kwangaphambili. Isiteji sangaphambi kokupholisa ngokuvamile sisebenzisa i-nitrogen noma i-nitrogen eyi-liquid njengendawo yokupholisa, futhi ngokusebenzisa imishini yokushintshanisa ukushisa, izinga lokushisa lomoya ocindezelwe liyancipha, lilungiselela inqubo ye-cryogenic elandelayo. Ngokusebenzisa ukupholisa kwangaphambili, izinga lokushisa lomoya lingancishiswa lisondele ekushiseni kwe-liquefaction, linikeze izimo ezidingekayo zokuhlukaniswa kwezingxenye emoyeni.
Ukunwetshwa kwezinga lokushisa eliphansi nokuhlukaniswa kwegesi
Ngemuva kokuthi umoya ucindezelwe futhi upholiswe ngaphambili, isinyathelo esilandelayo esibalulekile ukunwetshwa kwezinga lokushisa eliphansi kanye nokuhlukaniswa kwegesi. Ukwandiswa kwezinga lokushisa eliphansi kufinyelelwa ngokwandisa ngokushesha umoya ocindezelwe nge-valve yokwandisa ukuya kungcindezi evamile. Phakathi nenqubo yokwandisa, izinga lokushisa lomoya lizokwehla kakhulu, lifinyelele izinga lokushisa lokuphuza. I-nitrogen ne-oxygen emoyeni kuzoqala ukuncibilika emazingeni okushisa ahlukene ngenxa yomehluko wamaphuzu abilayo.
Emshinini wokuhlukanisa umoya we-cryogenic, umoya owuketshezi ungena ebhokisini elibandayo, lapho umbhoshongo wokuhlukanisa uyingxenye ebalulekile yokuhlukaniswa kwegesi. Umgomo oyinhloko wombhoshongo wokuhlukanisa ukusebenzisa umehluko wamaphuzu abilayo wezingxenye ezihlukene emoyeni, ngegesi ekhuphukayo noma ewayo ebhokisini elibandayo, ukuze kuzuzwe ukuhlukaniswa kwegesi. Iphuzu elibilayo le-nitrogen lingu -195.8°C, elomoya-mpilo lingu -183°C, kanti ele-argon lingu -185.7°C. Ngokulungisa izinga lokushisa nokucindezela embhoshongweni, ukuhlukaniswa kwegesi okusebenzayo kungafinyelelwa.
Inqubo yokuhlukanisa igesi embhoshongweni wokuhlukanisa inembe kakhulu. Ngokuvamile, isistimu ye-fractionation yezigaba ezimbili isetshenziselwa ukukhipha i-nitrogen, umoya-mpilo, ne-argon. Okokuqala, i-nitrogen ihlukaniswa engxenyeni engenhla yombhoshongo wokuhlukaniswa, kuyilapho i-oxygen ye-liquid ne-argon igxilwe engxenyeni engezansi. Ukuze kuthuthukiswe ukusebenza kahle kokuhlukanisa, i-cooler kanye ne-evaporator kabusha ingangezwa embhoshongweni, ongaqhubeka nokulawula ngokunembile inqubo yokuhlukanisa igesi.
I-nitrogen ekhishiwe ivamise ukuba nokuhlanzeka okuphezulu (ngaphezulu kwama-99.99%), esetshenziswa kabanzi kwezensimbi, embonini yamakhemikhali, nakugesi. I-oksijeni isetshenziswa embonini yezokwelapha, yensimbi, nakwezinye izimboni ezisebenzisa amandla amaningi ezidinga umoya-mpilo. I-Argon, njengegesi engavamile, ivame ukukhishwa ngenqubo yokuhlukanisa igesi, ngokuhlanzeka okuphezulu futhi isetshenziswa kabanzi ekushiseni, ukuncibilikisa, nokusika i-laser, phakathi kwezinye izinkambu zobuchwepheshe obuphezulu. Isistimu yokulawula ezenzakalelayo ingalungisa amapharamitha enqubo eyahlukene ngokuya ngezidingo zangempela, ithuthukise ukusebenza kahle kokukhiqiza, futhi yehlise ukusetshenziswa kwamandla.
Ngaphezu kwalokho, ukwenziwa ngcono kohlelo lokuhlukanisa umoya olujulile lwe-cryogenic kuhlanganisa nobuchwepheshe bokugcina amandla kanye nokulawula ukungcola. Isibonelo, ngokubuyisela amandla ezinga lokushisa eliphansi ohlelweni, ukuchithwa kwamandla kungancishiswa kanye nokusebenza kahle kokusetshenziswa kwamandla kungathuthukiswa. Ngaphezu kwalokho, ngemithetho eqinile yezemvelo, imishini yesimanje yokuhlukanisa umoya ejulile ye-cryogenic nayo inaka kakhulu ekwehliseni ukukhishwa kwegesi eyingozi futhi ithuthukise ubungane bemvelo benqubo yokukhiqiza.
Izicelo zokuhlukaniswa komoya okujulile kwe-cryogenic
Ubuchwepheshe bokuhlukaniswa komoya obujulile be-cryogenic abugcini nje ngokuba nezicelo ezibalulekile ekukhiqizeni amagesi ezimboni, kodwa futhi budlala indima ebalulekile emikhakheni eminingi. Ezimbonini zensimbi, umanyolo, kanye ne-petrochemical, ubuchwepheshe obujulile bokuhlukanisa umoya we-cryogenic busetshenziselwa ukuhlinzeka ngamagesi ahlanzekile afana ne-oxygen ne-nitrogen, ukuqinisekisa izinqubo zokukhiqiza eziphumelelayo. Embonini ye-elekthronikhi, i-nitrogen ehlinzekwa ngokuhlukana komoya ojulile we-cryogenic isetshenziselwa ukulawula umoya ekukhiqizeni ama-semiconductor. Embonini yezokwelapha, umoya-mpilo ohlanzekile kakhulu ubalulekile ekwesekeni ukuphefumula kweziguli.
Ngaphezu kwalokho, ubuchwepheshe bokuhlukaniswa komoya obujulile be-cryogenic bubuye bubambe iqhaza elibalulekile ekugcinweni nasekuthuthweni kwe-oxygen ewuketshezi kanye ne-nitrogen ewuketshezi. Ezimweni lapho amagesi anomfutho ophezulu engakwazi ukuthuthwa, umoya-mpilo owuketshezi kanye ne-nitrogen ewuketshezi kunganciphisa ngempumelelo umthamo kanye nezindleko zokuthutha eziphansi.
Isiphetho
Ubuchwepheshe bokuhlukaniswa komoya obujulile be-cryogenic, obunamandla okuhlukanisa igesi asebenzayo nanembile, busetshenziswa kabanzi emikhakheni ehlukahlukene yezimboni. Ngokuthuthuka kobuchwepheshe, inqubo ejulile yokuhlukanisa umoya we-cryogenic izohlakanipha futhi isebenzise amandla, kuyilapho ithuthukisa ukuhlanzeka kokuhlukaniswa kwegesi nokusebenza kahle kokukhiqiza. Esikhathini esizayo, ukusungulwa kobuchwepheshe bokuhlukaniswa komoya obujulile be-cryogenic mayelana nokuvikelwa kwemvelo kanye nokubuyiswa kwezinsiza nakho kuzoba isiqondiso esibalulekile sokuthuthukiswa kwezimboni.
