Clean production process of titanium dioxide with ammonium sulfate and titanium co production method is determined as the key supporting technology

Recently, the Sinopec Federation and the China Chemical Industry Environmental Protection Association released the Catalog of Supporting Technologies for Environmental Protection and Clean Production in Petroleum and Chemical Industry for the first time. A total of 185 supporting technologies have been promoted and applied in the industry, including 60 key supporting technologies. The company's "clean production process of titanium dioxide with ammonium sulfate and titanium co production method" was determined as the key supporting technology. This is the state's affirmation and recognition of the company's energy conservation, emission reduction and cleaner production. For many years, the company has always taken clean production, energy conservation and emission reduction, and circular economy as the key points for the company's industrial upgrading. In terms of co production, emission reduction and energy conservation of titanium dioxide production process, it is in the forefront of the whole industry.

The technology of "new titanium dioxide cleaner production process with ammonium sulfate and titanium co production method" is mature, and the effect of energy saving, consumption reduction and emission reduction is obvious. The quality, mineral consumption, comprehensive energy consumption and water consumption of titanium dioxide products have reached the international advanced level in the same industry. The high-quality rutile titanium dioxide produced by this process has some quality indicators better than those of the products produced by the chlorination process. It has unique advantages in the comprehensive utilization of resources, energy conservation and emission reduction, and has an important demonstration role and promotion value in promoting the upgrading and structural adjustment of China's titanium dioxide industry.
