Product process

Chlorination: titanium tetrachloride is produced by reaction of titanium residue, artificial rutile, or natural rutile with chlorine gas from raw materials containing titanium, and then purified by distillation, followed by gas phase oxidation; After rapid cooling, TiO2 was obtained by gas-solid separation. Due to adsorption of a certain amount of chlorine, the TiO2 needs to be removed by heating or steam treatment. The process is simple, but the condition of 1000 ℃ or higher chloride, there are many chemical engineering problems such as chlorine, chlorine oxide, titanium tetrachloride and high corrosion, need to be solved, combined with the raw materials used in the special, compared with the high cost of sulfuric acid method. Chlorination production is continuous production, the flexibility of production device operation is not large, open and shut down and production load is not easy to adjust, but its continuous process production, the process is simple, less process control points, product quality is easy to achieve optimal control. In addition, the sintering process without rotary kiln calcining can easily depolymerize the original TiO2 particles, so it is generally considered that the quality of titanium dioxide produced by chloride method is better. The advantages of chlorination are short process, easy expansion of production capacity, high degree of continuous automation, relatively low energy consumption, “three wastes” less, can get quality products. Its disadvantages are large investment, complex equipment structure, high requirements for materials, high temperature resistance, corrosion resistance, difficult maintenance equipment, research and development difficulty.
