Abstract

Abstract

Boiling chlorination has become the mainstream production method of tetrachloride production due to its advantages of high production efficiency, low cost, little environmental pollution and high automation. Combined with the research practice in Sunrui Wanji titanium industry company, this paper mainly discussed the process of removing aluminum, vanadium and solid impurities in titanium tetrachloride during the process of boiling chlorination production. By combining the on-line detection technology of oxygen and carbon impurities in refined titanium tetrachloride to accurately remove aluminum, we independently developed and designed a chlorination furnace multi-cyclone separation system, titanium tetrachloride centrifugal separation system and vacuum stirring evaporation system to remove the solid particle impurities in titanium tetrachloride, which can meet the requirements of high-quality titanium tetrachloride preparation. And it is believed that the vanadium removal by organic matter and the environmentally friendly recycling technology of solid particles in titanium tetrachloride will become the mainstream production technologies of titanium tetrachloride industry.
