China Drying Network News The Shanxi Coal Industry Group's Hubei Saning Chemical Industry Co., Ltd. cooperated with Huazhong Normal University to carry out the industrialization application project of wet-process phosphoric acid refining technology, which has recently been listed as a major science and technology project in Hubei Province.
At present, a 100,000-ton/year wet-process phosphoric acid refining unit is currently under construction, which can produce a production capacity of 100,000 tons/year of phosphoric acid and 50,000 tons/year of industrial monoammonium phosphate. Prior to this, the two parties had already established a set of 10,000-ton refined phosphoric acid test equipment and completed trial production. The research and development and promotion of wet phosphoric acid refining technology can promote the development of China's phosphorus chemical industry and the development of phosphorus chemical refinement.
It is understood that foreign countries have realized the industrialization of wet-process phosphoric acid refining technology as early as the 1970s, and China began to conduct research on the refining technology of wet-process phosphoric acid in the 1990s. So far, only 100,000 tons/year of the equipment used by Guizhou Hongfu in the introduction of imported technology, 50,000 tons/year of the equipment used by Sichuan Chemical Technology Co., Ltd. and Sinochem Chongqing Fuling Chemical Company have been used in the construction of China Southern Normal University. 10,000 tons/year device. The above three sets of devices are all solvent extraction production processes. Among them, the technology of Huazhong Normal University has the advantages of short process flow, low by-product tailings, high extraction rate, and high phosphorus utilization rate.
