Titanium-lined hlab ntsha tuaj yeem siv rau evaporation (concentration) lossis distillation lossis cov tshuaj tiv thaiv hauv cov kua qaub tsis muaj zog lossis lwm cov tshuaj chloride uas muaj cov tshuaj, thiab rau nitridation ntawm cov khoom siv organic nrog nitric acid thiab tshuaj lom neeg nrog rau lwm yam co-oxidizing media. Lub nkoj siv rau cov tshuaj tiv thaiv kuj yog lub nkoj nrog titanium hauv ob sab phlu. Cov kev daws teeb meem uas muaj chromic acid thiab chromic acid daws rau vulcanization tuaj yeem siv lub thawv titanium-lined nyob ntawm qhov ntsuas kub.
Hauv qee daim ntawv thov ntau yam hauv kev lag luam chemical raw khoom, nws tau raug lees paub tias tooj liab thiab lwm yam kev daws teeb meem uas muaj roj siv los catalytically oxidize carbon chlorine tebchaw, thiab tuaj yeem siv los ua ib qho catalyst thaum tus nqi pH raug txiav txim. Tom qab ntawd, thaum catalyzing ntawm qhov kub txog li 150 ~ 200t, cov khoom siv sib xws yuav tsum tau teeb tsa, thiab acetaldehyde ntau lawm cov cuab yeej ua los ntawm titanium yog dav siv. Titanium-lined towers, kav dej, li qub thiab cov twj tso kua qaub nrog rotors thiab stators yog txhua yam tsim los ntawm kev tsim cov titanium ntshiab. Acetic acid purification feem ntau siv cov kab distillation, thiab feem ntau ntawm cov khoom uas muaj nyob rau hauv lub fractionation theem yog ua los ntawm titanium. Xws li cov txheej txheem nruab nrab thiab cov khoom sib txuas ntawm cov yees siv nyob rau hauv distillation units.
Lub serpentine tube rhaub tuaj yeem tiv thaiv kev tsim cov hlau sulfates thiab tau sim ua kom muaj cua sov ntxiv los ntawm 30% piv nrog aluminized tooj liab serpentine raj cua sov. Rau cov urea reactor, thiaj li yuav tau txais (recycle) carbon dub thiab txo kev ntxhov siab, cov tshuaj tiv thaiv ntauwd nrog txoj kab uas hla ntawm 43m thiab ntev ntawm 8.2m uas tuaj yeem tiv taus qhov kub ntawm 120T thiab siab ntawm 130kPa. Cov tshuaj tiv thaiv ntauwd yuav tsum txo cov concentration ntawm cov pa roj thiab lwm yam roj. Siab, cov cuab yeej no yog ua los ntawm titanium.
Daim ntawv thov thaj chaw ntawm titanium tau nthuav dav ntxiv rau cov roj av thiab roj av kev lag luam. Titanium yog siv rau hauv cov khoom siv desalination los tsim cov dej tshiab lossis cov dej haus los ntawm cov dej hiav txwv lossis cov khoom siv los tsim cov organic acids. Nyob rau tib lub sijhawm, cov twj, cov kav dej thiab cov khoom siv hluav taws xob ua los ntawm cov welded titanium raj tau raug pov thawj ntseeg tau thiab ruaj khov hauv kev xyaum. Titanium phaj yog siv los ua titanium noob daim hlau rau cathodes thaum tooj liab electrolyzed.
