Iimpawu zeMveliso

Iiyunithi zoLwahlulo loMoya (ASUs) ziyinxalenye ebalulekileyo yamashishini amaninzi kwaye zidlala indima ebalulekileyo kwiinkqubo zokuvelisa ezifuna iigesi ezicocekileyo.Zisetyenziselwa ukwahlula izinto zomoya ezifana neoksijini, initrogen, iargon, ihelium kunye nezinye iigesi ezintle.I-ASU isebenza kumgaqo wefriji ye-cryogenic, ethatha ithuba leendawo zokubilisa ezahlukeneyo zezi gesi ukuze zihlukanise ngokufanelekileyo.

Inkqubo yokwahlula umoya iqala ngokucinezela kunye nokupholisa umoya kumaqondo obushushu aphantsi kakhulu.Oku kunokufezekiswa ngeendlela ezahlukeneyo, kubandakanywa ukunyibilika okwandisiweyo, apho umoya uyanda uze uphole kubushushu obuphantsi.Kungenjalo, umoya unokucinezelwa kwaye upholiswe phambi kokuba unyibilike.Emva kokuba umoya ufikelele kwisimo solwelo, unokwahlulwa kwikholamu yokulungisa.

Kwikholamu yedistillation, umoya wolwelo ufudunyezwa ngononophelo ukuwubilisa.Xa ukubilisa kusenzeka, kokukhona iigesi eziguquguqukayo ngakumbi, njengenitrogen, ebila ku--196°C, ziqala zibe ngumphunga.Le nkqubo ye-gasification yenzeke kwiindawo eziphakamileyo ezahlukeneyo ngaphakathi kwinqaba, evumela ukuba icandelo ngalinye legesi lihlulwe kwaye liqokelelwe.Ukwahlula kufezekiswa ngokuxhaphaza umahluko kumanqaku abilayo phakathi kweegesi.

Enye yezinto eziphawulekayo zesityalo sokuhlukanisa umoya kukukwazi ukuvelisa ubuninzi begesi ecocekileyo.Ezi gesi zisetyenziswa kwiintlobo ngeentlobo zemizi-mveliso, kuquka ukwenza intsimbi, ukwenziwa kweekhemikhali, kunye nokhathalelo lwempilo.Inqanaba lokucoceka eliphunyezwe yiyunithi yokwahlula umoya kubalulekile ukugcina umgangatho wemveliso, ukuphucula ukhuseleko kunye nokuqinisekisa ukusebenza kakuhle.

Ukuguquguquka kwesityalo sokuhlukana komoya nako kufanelekile ukuqatshelwa.Ezi yunithi zinokuyilwa ukuvelisa imixube yerhasi ethile efanelekileyo kwiimfuno ezahlukeneyo zeshishini.Ngokomzekelo, kwishishini le-steelmaking, iiyunithi zokuhlukana komoya zinokuthi ziqwalaselwe ukuvelisa i-oxygen-eriched gas, eyandisa ukutsha kunye nokwandisa ukusebenza kwesithando somlilo.Ngokufanayo, kwishishini lezonyango, iiyunithi zokwahlula umoya zivelisa ioksijini ecocekileyo esetyenziswa kunyango lokuphefumula kunye neenkqubo zonyango.

Ukongezelela, izityalo zokwahlula umoya zineenkqubo zokulawula eziphambili ezivumela ukubeka iliso kunye nokusebenza kude.Oku kuvumela ukulungiswa lula kwamazinga okuvelisa igesi, ukuqinisekisa ukusetyenziswa ngokufanelekileyo kwezibonelelo ngokwemfuno.Iimpawu ezizenzekelayo zinceda ukwandisa ukusetyenziswa kwamandla, ukwandisa ukusebenza kakuhle kunye nokunciphisa iindleko.

Ukhuseleko lubaluleke kakhulu kuwo nawuphi na umsebenzi woshishino.Izityalo zokuhlukana komoya ziyilwe ngeendlela ezahlukeneyo zokukhusela ukuqinisekisa impilo yabasebenzi kunye nokunyaniseka kwenkqubo.Ezi ziquka iinkqubo zokuvala ngokuzenzekelayo, iinkqubo ze-alamu kunye neevalve zokunciphisa uxinzelelo.Abaqhubi beplanti yokwahlula umoya bafumana uqeqesho olungqongqo lokusingatha naziphi na iimeko zonxunguphalo ezinokubakho kunye nokugcina ukhuseleko lokusebenza.

Ukuqukumbela, iiyunithi zokwahlula umoya ziyimfuneko ekwahluleni amacandelo omoya kwizicelo ezahlukeneyo zamashishini.Umgaqo wobushushu obuphantsi abawusebenzisayo unokwahlula ngokufanelekileyo iigesi kunye nokubonelela ngeemveliso ezicocekileyo.Ukuguquguquka, iinkqubo zolawulo oluphezulu kunye neempawu zokhuseleko zenza i-ASU ibaluleke kakhulu kumashishini ahlukeneyo kwihlabathi liphela.Njengoko itekhnoloji iqhubela phambili, iiyunithi zokwahlula umoya ziya kudlala indima ebaluleke kakhulu ekuhlangabezaneni nemfuno ekhulayo yegesi esulungekileyo.

Isicelo seMveliso

Iiyunithi zokwahlula umoya (ASUs) zidlala indima ebalulekileyo kumashishini ahlukeneyo ngokwahlula umoya kwiindawo zawo eziphambili, ezizezi, iNitrogen, iOxygen neArgon.Ezi gesi zisetyenziswa ngokubanzi kwisinyithi, i-petrochemical, ikhemikhali yamalahle, isichumisi, i-non-ferrous smelting, i-aerospace kunye nezinye iindawo.Iinkampani ezifana nezethu ezisebenza ngezixhobo zokwahlula umoya zibonelela ngoluhlu olubanzi lweemveliso ukuhlangabezana neemfuno ezahlukeneyo zala mashishini.

Iimveliso zethu zezityalo zokwahlula umoya ziyilwe ngononophelo kwaye zakhiwe ukuze kuqinisekiswe ukusebenza kakuhle kunye nokuthembeka okuphezulu.Ngobuchwephesha obuphezulu kunye nemilinganiselo yokulawula umgangatho ongqongqo, siyazingca ngokubonelela ngezixhobo zodidi lokuqala ezihlangabezana nemigangatho ephezulu yoshishino.

Elinye lamashishini aphambili axhamlayo ekusetyenzisweni kweeyunithi zokwahlula umoya yi-metallurgy.Ioksijini eveliswa ziiyunithi zokwahlula umoya isetyenziswa kwiinkqubo ezahlukeneyo zetsimbi ezifana nentsimbi kunye nentsimbi.Ukutyetyiswa kweoksijini kwandisa ukusebenza kakuhle kwesithando somlilo, okunciphisa ukusetyenziswa kwamandla kunye nokuphucula umgangatho wemveliso.Ukongezelela, i-nitrogen kunye ne-argon zisetyenziselwa ukuhlanjululwa, ukupholisa kunye njengendawo yokukhusela kwimisebenzi eyahlukeneyo ye-metallurgical.

Kwintsimi ye-petrochemical, iiyunithi zokwahlula umoya zibonelela ngomthombo oqhubekayo nothembekileyo weegesi zemveliso ezifunwa yinkqubo ezahlukeneyo.Ioksijini isetyenziselwa ukuvelisa i-ethylene oxide kunye nepropylene oxide, ngelixa i-nitrogen isetyenziswa njengomaleko ongasebenziyo ukukhusela ukuqhuma kunye nomlilo ngexesha lokugcinwa kunye nokuphathwa kwezinto ezinokutsha.Ukwahlula komoya kumacandelo awo kwiyunithi yokwahlula umoya kuqinisekisa ukunikezelwa rhoqo kwegesi efunekayo kwimisebenzi yepetrochemical.

Ishishini lemichiza yamalahle nalo lizuze lukhulu kwicandelo lokwahlula umoya.I-oksijini eveliswa yiyunithi yokwahlula umoya isetyenziselwa ukuguqulwa kwegesi yamalahle, inkqubo apho amalahle aguqulwa abe yigesi yokudibanisa ukuvelisa ukuveliswa kweekhemikhali.I-Syngas iqulethe i-hydrogen, i-carbon monoxide kunye nezinye izinto ezifunekayo ukuvelisa iikhemikhali ezahlukeneyo kunye namafutha.

Iiyunithi zokwahlula umoya zikwasetyenziswa kushishino lwesichumisi.I-nitrogen, eveliswa ngobuninzi ngexesha lokuhlukana komoya, yinto ebalulekileyo yokuvelisa izichumisi.Izichumisi ezisekelwe kwi-nitrogen zibalulekile ekukhuthazeni ukukhula kwezityalo okunempilo kuba i-nitrogen sisondlo esibalulekileyo kwizityalo.Ngokubonelela ngomthombo othembekileyo we-nitrogen, iiyunithi zokwahlula umoya zinceda ukuvelisa izichumisi ezikumgangatho ophezulu eziphucula iziphumo zezolimo.

Ukunyibilikiswa kwesinyithi esingenawo intsimbi, njengokuveliswa kwe-aluminium kunye nobhedu, kuxhomekeke kwitekhnoloji ye-ASU yokutyebisa ioksijini ngexesha lenkqubo yokunyibilikisa.Ukongezwa kweoksijini elawulwayo kwenza ulawulo oluchanekileyo lobushushu kunye nokwandisa ukubuyiswa kwesinyithi.Ukongezelela, i-nitrogen kunye ne-argon zisetyenziselwa ukuhlanjululwa kunye neenjongo zokuvuselela, ukuphucula ukusebenza kakuhle kunye nomgangatho wenkqubo.

Iiyunithi zokwahlula umoya zikwadlala indima ebalulekileyo kwishishini le-aerospace.Ngezi zixhobo, ulwelo kunye negesi yenitrogen kunye neoksijini inokuveliswa kwiinqwelomoya kunye neziphekepheke.Ezi gesi zisetyenziselwa ukunyanzeliswa kwe-cabin, i-tank ye-fuel inerting kunye neenkqubo zokutshisa kwizicelo ze-aerospace, ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle kwe-flight operations.

Isishwankathelo, iiyunithi zokwahlula umoya zinoluhlu olubanzi lwezicelo kumashishini amaninzi.Fumana unikezelo oluthembekileyo lwe-nitrogen, i-oksijini kunye ne-argon ngokusebenzisa iyunithi yokwahlula umoya ukuxhasa ukusebenza kakuhle kweenkqubo ezahlukeneyo ezifana nesinyithi, i-petrochemical, ikhemikhali yamalahle, isichumisi, i-smelting non-ferrous, kunye ne-aerospace.Njengenkampani ekhethekileyo kwizixhobo zokwahlula umoya, sinikezela ngeemveliso ezahlukeneyo ezihlangabezana neemfuno ezingqongqo zala mashishini, ukuqinisekisa ukusebenza ngokungenamthungo kunye nemveliso ekumgangatho ophezulu.
