The titanium dioxide industry has entered an important turning period

accelerating technological upgrading and popularizing cleaner production

at present, China's titanium dioxide industry has entered an important turning period of promoting industrial layout adjustment, technological upgrading and transformation, and the popularization of cleaner production. Among them, the development path of titanium dioxide industry by chlorination is difficult, but the prospect is bright. This is the consensus reached by the delegates at the 2012 national titanium dioxide industry annual conference held in Nanning, Guangxi on December 1

Li Shousheng, executive vice president of the China Federation of petroleum and chemical industries, said at the meeting that the sulfuric acid process is absolutely dominant in China's titanium dioxide industry, but the "three wastes" and by-products from the production of titanium dioxide by the sulfuric acid process are more likely to cause environmental pollution. It is understood that in 2011, among the 55 manufacturers in China's titanium dioxide industry, only Jinzhou titanium industry adopted the chlorination process, and its output accounted for less than 2% of the total national output that year

Li Shousheng stressed that the petroleum and chemical industry should earnestly implement the spirit of the 18th CPC National Congress in 2013, in which the key task of titanium dioxide industry is to fully accelerate the adjustment of industrial structure, strengthen scientific and technological innovation, comprehensively promote care, vigorously strengthen basic management, and strive to make breakthroughs in industrial transformation and upgrading, scientific and technological innovation, energy conservation and emission reduction, ecological civilization construction and economic efficiency improvement, In order to realize the leap from a large titanium dioxide production country to a powerful production country, China will win new opportunities, new advantages and new future

Zhang Biao, director of the Industrial Coordination Department of the national development and Reform Commission, said that the "12th Five Year Plan" for the comprehensive utilization of vanadium and titanium resources and industrial development, which was recently released, made clear provisions on market access and proposed to transform and upgrade the existing titanium dioxide production line by sulfuric acid process on the premise of strictly controlling the new production capacity. The main reason is that foreign countries have imposed a blockade on China in the process technology of titanium dioxide by chlorination. China's independent research and development will take some time. At present, there is no foundation for popularization. In addition, the existing sulfuric acid production line still has a lot of room for improvement in circular economy and cleaner production. Therefore, the plan allows enterprises to upgrade and transform the existing titanium dioxide production line by sulfuric acid method through integration and reorganization, increase investment, and cooperate with StarTech technicians to reasonably transform the universal experimental machine according to the experimental requirements, set up a set of sulfuric acid preparation devices and waste acid and ferrous sulfate comprehensive utilization devices, so as to meet the requirements of cleaner production

sun Lianying, President of China Paint Industry Association, also believes that the plan allows the transformation and upgrading of the existing titanium dioxide production line by sulfuric acid method on the premise of setting a threshold, which is not contradictory to the restriction on the new titanium dioxide production line by sulfuric acid method in the Guiding Catalogue for industrial structure adjustment (2011 Edition). In addition, sun Lianying revealed that at present, the association is assisting the Ministry of environmental protection to carry out policy research on cleaner production technology in the titanium dioxide industry. Now, in order to reduce the weight, the titanium dioxide industry sometimes adopts non-ferrous metals and special metals such as aluminum alloy, and will strive to promote green development, circular development and low-carbon development, so as to reverse the trend of ecological environment deterioration from the source

Bi Sheng, director of the titanium dioxide sub center of the National Productivity Promotion Center of the chemical industry, told that at present, there are a total of 6 chlorinated titanium dioxide projects under construction and implementation. According to Xie Xiangyun, chairman of titanium dioxide industry branch of China National titanium dioxide industry association, the total production capacity of titanium dioxide in China will increase to 3.4 million tons by 2015, of which the production capacity of titanium dioxide by chlorination method will reach more than 300000 tons. The industrial and product structure will develop in a more reasonable direction, that is, the size of mold cavity at 23 ℃ ± 0.1 ℃ and the placement for 24 hours after forming

this meeting was co sponsored by the titanium dioxide industry branch of China paint industry association and the titanium dioxide branch of the National Productivity Promotion Center of the chemical industry
