Inqaba yokwahlula umoya sisixhobo esibalulekileyo esisetyenziselwa ukwahlula iinxalenye eziphambili zegesi emoyeni kwinitrogen, ioksijini, kunye nezinye iigesi ezinqabileyo. Ukuhamba kwenkqubo yayo ikakhulu kubandakanya amanyathelo afana nokunyanzeliswa komoya, ukupholisa kwangaphambili, ukucocwa, ukupholisa, kunye ne-distillation. Ulawulo oluchanekileyo lwenyathelo ngalinye lubalulekile ekuqinisekiseni ukucoceka kunye nokuzinza kweemveliso zerhasi zokugqibela. Eli nqaku liza kubonelela ngentshayelelo eneenkcukacha kwinkqubo yokuhamba kwenqaba yokwahlukana komoya.

1. Ukunyanzeliswa komoya kunye nokupholisa kwangaphambili

Inyathelo lokuqala kwinkqubo yokwahlulahlula umoya kukucinezela umoya we-atmospheric. Ngezigaba ezininzi ze-compressor zomoya, umoya uxinzelelwe kuxinzelelo lwe-5-7 bar. Ngexesha lenkqubo yoxinzelelo, iqondo lokushisa lomoya ocinezelweyo liyenyuka, ngoko ke ii-coolers eziphakathi kunye ne-post-coolers zisetyenziselwa ukuthoba ubushushu bomoya. Ukuthintela ukuba i-compressor yonakaliswe ngokungcola emoyeni, iincinci ezisemoyeni zisuswa ngeefilitha. Umoya ocinezelweyo emva koko uthunyelwa kwisixokelelwano sokupholisa kwangaphambili ukuze uphole ngakumbi, ngokuqhelekileyo kusetyenziswa amanzi okupholisa okanye izikhenkcisi ezifana neFreon, ukupholisa umoya malunga ne-5°C.

2. Ukucocwa koMoya kunye nokuphelelwa ngamanzi emzimbeni

Emva kokupholisa kwangaphambili, umoya uqulethe inani elincinci lokufuma kunye ne-carbon dioxide. Oku kungcola kunokwenza umkhenkce kumaqondo aphantsi kunye nezixhobo zokuvala. Ngoko ke, umoya kufuneka uhlanjululwe kwaye uphelelwe ngamanzi. Le nkqubo ngokuqhelekileyo isebenzisa iinqaba ze-molecular sieve adsorption, ngokusebenzisa i-adsorption ngamaxesha kunye neenkqubo zokuhlaziya ukususa umphunga wamanzi, i-carbon dioxide, kunye ne-hydrocarbons, njl., ukuqinisekisa ukusebenza kakuhle kweenkqubo ezilandelayo zobushushu obuphantsi. Umoya ococekileyo ucocekile kwaye womile, ufanelekile kwiinkqubo zokupholisa kunye nokwahlula okulandelayo.

3. IsiTshintshisi esiPhambili soBubushushu Ukupholisa Umoya

Umoya ocociweyo upholisiwe kwi-heat exchanger engundoqo ngokupholisa okunzulu. Ubushushu obuphambili sesona sixhobo sibaluleke kakhulu kwinkqubo yokwahlulahlula umoya. Umoya okwindawo yokutshintsha ubushushu utshintshana nobushushu obuhlukeneyo kunye nenitrogen ebandayo kunye neoksijini, ukwehlisa ubushushu balo ukuvala ubushushu botywala. Ukusebenza kokutshintshana kobushushu ngexesha le nkqubo kuchaphazela ngokuthe ngqo ukusetyenziswa kwamandla kunye nokucoceka kwemveliso yokugqibela yenqaba yokwahlula umoya. Ngokuqhelekileyo, ipleyiti ye-aluminiyam esebenzayo yokutshintsha ubushushu isetyenziselwa ukuphucula ukusebenza kakuhle kokutshintshisa ubushushu.

4. Inkqubo yokwahlula kwi-Distillation Tower

Umoya opholileyo uthunyelwa kwinqaba ye-distillation yokwahlula usebenzisa umahluko kwiindawo zokubilisa zamacandelo ahlukeneyo emoyeni. Umoya unyibilika ngokuthe ngcembe kumaqondo obushushu aphantsi, wenze umoya olwelo. Lo moya wolwelo ungena kwinqaba yedistillation ukwenzela ukusebenzisana okuninzi phakathi kwezigaba zegesi kunye nolwelo. Kwinqaba ye-distillation, i-oksijini, i-nitrogen, kunye neegesi ezinqabileyo ezifana ne-argon ziyahlukana. I-oxygen concentration ikhula ngokuthe ngcembe ezantsi kwinqaba, ngelixa i-nitrogen ihlukaniswe phezulu. Ngokuxutywa kwe-distillation, i-oxygen ecocekileyo kunye ne-nitrogen inokufumaneka ngokucoceka okuphezulu.

5. Ukukhutshwa kwe-Oxygen kunye neeMveliso zeNitrojeni

Ukutsalwa kweoksijini kunye nenitrogen linyathelo lokugqibela lenqaba yokwahlula umoya. Ioksijini yolwelo kunye nenitrogen zohlulwe kwinqaba yedistillation kwaye zifudunyezwe zibuyele kwiqondo lobushushu begumbi ngokutshintshisa ubushushu ukufikelela kwimeko yegesi efunwayo. Ezi mveliso zegesi zithunyelwa ngakumbi kwiitanki zokugcina okanye zinikezelwe ngokuthe ngqo kubasebenzisi. Ukuphucula ukusebenza kakuhle kwenkqubo kunye nokucoceka kwemveliso, isakhiwo se-double-tower ngamanye amaxesha senzelwe ukwahlula i-argon kwi-oksijini kunye ne-nitrogen yokusetyenziswa kwezoshishino.

6. Ukulawula kunye nokuPhucula

Yonke inkqubo yokwahlukana komoya ibandakanya inkqubo yokulawula eyinkimbinkimbi, efuna ukubeka iliso ngexesha langempela kunye nokulungelelaniswa koxinzelelo, ukupholisa, ukutshintshwa kobushushu, kunye neenkqubo zokwahlula ukuqinisekisa umgangatho weemveliso zokugqibela. Iinqaba zokwahlulwa komoya zale mihla ziqhele ukuxhotyiswa ngeenkqubo zolawulo oluzenzekelayo, zisebenzisa izinzwa kunye nesoftware yokulawula ngokuchanekileyo iparamitha ezinje ngobushushu, uxinzelelo, kunye nokuhamba ukuze kunyuswe inkqubo yokusetyenziswa kwamandla kunye nokucoceka kwemveliso yerhasi.

Ukuhamba kwenkqubo yenqaba yokwahlukana komoya kubandakanya amanyathelo amaninzi afana nokunyanzeliswa komoya, ukupholisa kwangaphambili, ukucocwa, ukupholisa okunzulu, kunye ne-distillation. Ngezi nkqubo, ioksijini, initrogen, neegesi ezinqabileyo ezisemoyeni zinokwahlulwa ngokufanelekileyo. Ukuphuhliswa kweteknoloji yenqaba yokwahlula umoya yanamhlanje yenze inkqubo yokwahlula isebenze ngakumbi kwaye isebenzise amandla aphantsi, nto leyo ibaluleke kakhulu ekusetyenzisweni kweegesi zamashishini.
