Chlorination process titanium dioxide process

Chlorination is a relative term defined in sulfuric acid, chlorination of titanium white are the following three processes.
① high-grade iron ore or a titanium natural rutile, synthetic titanium-rich material, production of crude chlorination process using TiCl _4; TiCI ₄ through crude purification system pure fine TICI _4.
2 refined TiC1 ₄ gas phase oxidation to obtain rutile-type Ti0 ₂ particles in accordance with the pigment properties.
3 Post-treatment Similar to the sulfuric acid process, producing products that are suitable for different uses.
Because the post-treatment process and equipment are similar to the sulfuric acid process, the chlorination process focuses on the first two items. The process chart of the chlorination titanium white process is shown in Figure 1. The post-processing process is shown in Figure 2.

The oxidizing furnaces in the chlorination process of the world are basically docked with the boiling chlorination furnace. Only the Jinzhou plant in China successfully realized the docking of the molten salt chlorination furnace and the oxidizing furnace.
