Description
Titanium tetrachloride is mainly used for producing titanium sponge and titanium dioxide, and can also be used as a catalyst, pH regulator and water treatment product, laboratory chemical, metal surface treatment product, non-metal surface treatment product and metalworking fluid; Titanium tetrachloride (i.e. hydrogen bromide) is modelled as a pure substance; when modelling this substance, the user is required to add a solvent of their choice in the model. The dataset includes the main raw and auxiliary materials, energy, atmospheric emissions, wastewater and solid waste of the production process, in which the preliminary treatment of wastewater in the utility/auxiliary processes and the waste-gas treatment process are included within the dataset boundary, while infrastructure such as the manufacture of production equipment and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources; the production activities of this product include chlorination, dust collection and absorption, settling, rectification, residue removal and tail-gas treatment and other processes.
Activity Description
The production activities of this product include chlorination, dust collection and absorption, sedimentation, distillation, slag removal and tail gas treatment.
Process Description
Titanium tetrachloride, chemical formula: TiCl4, CAS number: 7550-45-0. Colorless to light yellow transparent liquid, non-combustible, with pungent odor. Relative density 1.726, melting point -30℃, boiling point 136.4℃, soluble in ethanol, dilute hydrochloric acid, hydrofluoric acid, etc. Titanium tetrachloride is chemically unstable and decomposes when exposed to water to form insoluble hydroxychloride and hydroxide. It decomposes into titanium dioxide and hydrogen chloride in humid air and emits white smoke. This substance is mainly used to make titanium sponge and titanium dioxide, and can also be used as catalysts, pH regulators and water treatment products, laboratory chemicals, metal surface treatment products, non-metallic surface treatment products and metal working fluids.

Technology comment
Add the high titanium slag and petroleum coke into the preheated chlorination furnace. When the high titanium slag and petroleum coke are heated to 800-1000 degrees Celsius, chlorine gas is introduced. The chlorine reacts with TiO2 and impurities FeO, MnO2, SiO2, etc. in the high titanium slag. The corresponding chloride is generated. After the reaction, the chlorination furnace gas is collected and cooled, and the recovered crude TiCl4 is washed with liquid TiCl4. The impurities in the crude TiCl4 are then removed through the original refining process to obtain TiCl4 that meets the standards. The core chemical reaction equation of this process is: TiO2+2Cl2+C=TiCl4+CO2.
