With the improvement of titanium dioxide boom in recent years, leading companies in the industry have expanded their production. However, since sulfuric acid titanium dioxide has been listed as a product with high energy consumption and high pollution since 2007, it strictly controls environmental protection. "Sulfuric acid process titanium dioxide production equipment" is listed as the category of industrial structure adjustment restrictions. New sulfuric acid process titanium dioxide production line projects are not allowed. The increase in sulfuric acid process production capacity can only rely on the technical transformation and expansion of existing manufacturers. At the same time, due to the more advantages of the chlorination process, under the restriction of domestic environmental protection policies, the chlorination process has become the development trend of the domestic titanium dioxide process in China, and the domestic enterprises that can master the chlorination process titanium dioxide technology are expected to be further improved in the future market share.

Due to the relatively high technical barriers of the chlorination process, only domestic listed companies including Lomon Baili, Lubei Chemical, Pangang Vanadium and Titanium have mastered the relevant technology. In the chloride process titanium dioxide technology is mainly the treatment technology of oxidation reactor scarring and titanium reduction technology. Lubei Chemical has previously stated that Xianghai Titanium, a subsidiary of the company, has mastered the scarring technology that restricts the operation cycle of the oxidation section. Effectively delay the scarring of the oxidation furnace commonly encountered in the production of chlorination titanium dioxide, and has a special titanium reduction process, so that the high-titanium slag used in the chlorination production line can be further reduced with the same grade raw materials as the sulfuric acid production line Purification, effective control of production costs.
