The technologies of oxidation process in the main foreign titanium dioxide manufacturers adopting chloride process,such as Dupont,Kronos,Tronox and Cristal Global were studied in this paper with emphasis on the structures of oxidation reactor and crusting removal technique.The results show that all the mentioned four large-scale companies adopt the similar charging methods that O2 and TiCl4 are preheated to maintain the smooth operation of gas phase oxidation,and the ektexine of burner is protected by forced cooling.So far,oxidation reactor with relatively small diameter is preferred for titanium dioxide production with chloride process by these large-scale manufacturers,and the methods including mechanical scraping,sand blasting,gas film protection or combined sand blasting and gas film are usually employed for the crusting removal on the oxidation reactor.
