industry development is particularly concerning, sulfuric acid method, chlorination method in the "13th Five-Year Plan" period how to position?" In a longer period of time in the future, chlorination and sulfuric acid two production processes will coexist, the industry will be more stringent environmental regulations and norms of development, for the limited sulphuric acid method to produce titanium dioxide process, the industry should strictly implement the relevant provisions of the state, led by the Association to organize self-discipline self-examination, on the basis of self-examination of the United Nations environmental protection department for violations of the severe sanctions. During the 13th Five-Year Plan period, the merger and reorganization of the titanium dioxide industry will be intensified and accelerated in line with international standards. "At the 2015 China (Deyang) Phosphorus Titanium Chemical Green Development High-End Forum held on December 8-9, experts made a detailed analysis and outlook on the development of the titanium dioxide industry during the 13th Five-Year Plan period.The
conference focused on the development of phosphorus titanium chemical "green, fine, transformation, innovation" theme, through visits, academic reports, results negotiations and other forms, combing the development strategy of the phosphorus titanium chemical industry, discuss the direction of industrial technology, and strive to become the national phosphorus chemical and titanium chemical academic exchanges, information sharing and results transformation of the long-term platform.
on the development of titanium dioxide industry, expert analysis said: chlorination is the current world titanium dioxide production technology mainstream, representing the direction of industrial development. However, due to the lack of titanium ore resources applicable to chlorination process in China, it is necessary to import titanium raw materials at high prices, which seriously restricts the development of chlorination process. In recent years, a group of scientific research institutions represented by Angang Group's Research Institute are committed to the process of chlorinated titanium dioxide "eating" domestic raw materials, and have achieved gratifying results.
Such as Angang Group Research Institute to Sichuan Panzhihua titanium iron ore as raw materials for the development of titanium slag upgrade processing process, to solve the chlorinated titanium dioxide process of the "water and soil do not accept" problem has brought about a turnaround. They take titanium ore as raw material in Phangxi region, through the titanium slag upgrade process to obtain high-quality titanium-rich materials, its titanium dioxide content of 88% to 95%, silicon dioxide content of less than 2.5%, calcium oxide less than 0.15%, magnesium oxide less than 1%, composition indicators and particle size to fully meet the raw material requirements of the boiling chloride titanium dioxide production process.
Xu Xingrong, deputy chief engineer of Donghua Engineering Technology Co., Ltd., believes that the "Strictest Standard for emissions of pollutants from the petrochemical industry" in history will be implemented in existing enterprises from July 1, 2017, which will have more severe restrictions on existing titanium dioxide enterprises with sulphuric acid method, and the chlorination process will usher in an opportunity for development.
experts agree that the key to the development of titanium dioxide by sulfate is clean production and circular economy. Such as Sichuan Longyu Group relying on the rich iron and titanium resources in Panzhihua area, accelerate the development of circular sulfuric acid titanium dioxide process, resource utilization rate continues to improve, energy consumption has dropped significantly. Zhou Xiaokui, vice president of the group, said that the sulfuric acid method titanium dioxide powder has a unique quality performance, in the future for a long time will be the mainstream varieties in China, so to accelerate the realization of sulfuric acid method titanium white powder waste waste resources comprehensive utilization and clean production is the key to the sulfuric acid method process.
Fu Ijiang, deputy secretary-general of the China Titanium White Powder Industry Association, said that in this situation, the titanium dioxide industry on the one hand should vigorously research and develop chlorination process, so that it matures as soon as possible; During the "13th Five-Year Plan" period, the progress of reorganization and merger will be accelerated, and a number of key enterprises with greater development potential and world influence should be built. In the coming period, the clean production and circular economy of titanium dioxide production in China's sulfate method is the only way, chlorination technology needs to be broken through and perfected to form a production scale, market recognition of high-grade products, in order to truly enter the "chlorination" era, that is, China's titanium dioxide international discourse era.
