[Chinese Titanium Dioxide Network News] After nearly 60 years of development, the titanium dioxide industry in China has explored a variety of valuable experiences in the transition from extensive production management to cleaner production and refined management. If 2017 is the first year of the green development of China's titanium dioxide industry, then in 2018, it will become a deepening year for the green development of the industry.

    At present, the main process for the production of titanium dioxide in China is still sulfuric acid, and the proportion of titanium dioxide production by chlorination is still less than 15%. After many years of exploration in the production of sulphate titanium dioxide, great progress has been made. The backbone enterprises adopt the advanced co-production process, sulfur-titanium, sulfur-phosphorus-titanium, sulfur-iron-titanium, sulfur-ammonium-titanium, and titanium- The industry chain of sulfur-iron and other circular economy has blossomed. The entire industry has done a lot of work in energy saving and emission reduction, improving product quality, “three wastes” treatment and disposal, safety management, and recycling. As China's environmental protection requirements become stricter and environmental protection awareness continues to increase, the titanium dioxide industry has also been increasing year by year in terms of energy conservation, emission reduction and environmental protection investment, and has been hurrying toward clean production and green manufacturing standards.

    In 2017, Ningbo Xinfu Titanium Dioxide Co., Ltd. introduced the third-party environmental service project of the Ministry of Environmental Protection—a comprehensive pilot project for acidic wastewater treatment, which enabled the reduction rate of acidic wastewater to reach 89%, the recycling rate of water to reach 85%, and the external sulfuric acid The recycling rate reaches 90%, the use of acid-alkali neutralizing lime is reduced by 90%, and the production of titanium gypsum waste residue is reduced by 90%. Subsequently, Shandong Dongjia Group and Yunnan Datongtong Industry & Trade Co., Ltd. initiated the comprehensive treatment project for acidic wastewater; Dawn Titanium Industry and Qianjiang Fangyuan Titanium etc. are actively promoting the construction of green chemical plants; Guangdong Huiyun Titanium Industry, Guangxi Jinmao Titanium Industry, Nanjing Taibai Chemical Industry, Shandong Lubei Enterprise Group and other enterprises actively use the recycling economy technology to solve the "two high" problem of sulfuric acid titanium dioxide, forming a unique circular economy technology.

    The titanium dioxide industry has adopted the principle of supply-side structural reforms, and has increased investment in energy conservation, emission reduction, environmental protection, and new product development, and has achieved initial success. In 2017, under the impetus of the energy consumption limit of titanium dioxide per unit product, industry enterprises adopted various methods to achieve energy conservation and emission reduction, which not only reduced consumption and emissions, but also reduced production costs and improved the competitiveness of industries and enterprises.

    The preparation of the "Technical Code for Titanium Dioxide Industrial Wastewater Treatment Project" by the Ministry of Environmental Protection and the formulation of the "Sulfuric Acid Process Titanium Gypsum Standard" have also started in 2017. With the implementation of various policies and standards, the entire industry will be in the "13th Five-Year Plan" period. It will further promote “three go ones, one drop and one supplement”, vigorously eliminate backward devices and processes, and endeavor to build upstream and downstream supporting green industrial chains and industrial bases to form new agglomeration effects and scale advantages. In the 2018 year when the green development of the industry will deepen, the high energy consumption and high pollution “double-high” problem faced in the production of sulfuric acid titanium dioxide will enter the final stage.

    At the same time, China is the world's largest producer of titanium dioxide, but also a major exporter of titanium dioxide. According to statistics, in 2011, the export volume of titanium dioxide in China was only 380,000 tons. From January to November 2017, the export volume has reached nearly 750,000 tons. It is estimated that the annual export volume will be about 900,000 tons. In 2018, the export momentum of titanium dioxide in China is expected to continue to be good. The annual export volume will exceed 1 million tons; the total sales volume at home and abroad is expected to increase by more than 6%. Especially for new materials such as lithium titanate
