Description
This dataset is a market dataset representing the consumption market of the region. The dataset includes the transport of the product from the gate to the consumption end, and the transport service is calculated based on the transport situation of the product in the region. Titanium dioxide is an inert inorganic chemical pigment, with important uses in industries such as coatings, inks, papermaking, plastics and rubber, chemical fibers and ceramics; this dataset is modeled with titanium dioxide as a pure substance, and includes the main raw and auxiliary materials, energy, air emissions and waste of the production process, and infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources; the production activity of this product includes the chlorination refining section (batching, fluidized chlorination, cooling, cyclone separation, first- and second-stage condensation, vanadium-removal rectification, condensation), the oxidation section (preheating, oxidation reaction, cooling, bag filtration, discharge, slurrying and dechlorination), and the post-treatment section (dispersion wet milling, classification, primary surface treatment, filtration and washing, flash drying, bag dedusting, steam micronization, secondary surface treatment, bag filtration), but does not include waste gas treatment processes such as water washing and alkali absorption.
Activity Description
The production activities of this product include the chlorination and refining section (batching, boiling chlorination, cooling, cyclone separation, first and second condensation, vanadium removal distillation, condensation), oxidation section (preheating, oxidation reaction, cooling, bag filter, discharge, beating and dechlorination), post-treatment section (dispersive wet grinding, classification, primary surface treatment, filter washing, flash drying, bag dust removal, steam powder, secondary surface treatment, bag filtration), but does not include waste gas treatment processes such as water washing and alkali absorption.
Process Description
Titanium dioxide, also known as TiO2, has a CAS number of 13463-67-7. It is a soft, odorless and tasteless white powder with strong hiding power and tinting strength, with a melting point of 1560–1580°C. It is insoluble in water, dilute inorganic acids, organic solvents, and oils; slightly soluble in alkalis; and soluble in concentrated sulfuric acid. It turns yellow when heated and reverts to white upon cooling. As an inert pigment, it is considered the best-performing white pigment available in the world. Rutile titanium dioxide is dominant in China, accounting for approximately 86.5% of total production in 2023.

Technology comment
The production of rutile titanium dioxide currently involves the coexistence of the "sulfuric acid method" and the "chlorination method". Among them, the sulfuric acid method occupies an absolutely dominant position in production capacity, and the chlorination method represents the future technological development direction. In 2023, in the classification of titanium dioxide production methods in China, sulfuric acid titanium dioxide was still the main production method, with an annual output of approximately 3.468 million tons, accounting for 83.37%, while China's comprehensive output of chloride titanium dioxide accounted for 16.63%. In the chloride titanium dioxide production process, it is mainly divided into boiling chlorination method and molten salt chlorination method. Among them, boiling chlorination method is the main chlorination method to produce titanium dioxide.
