On July 31, the ammonium sulphate concentrate ammonium phosphate process successfully developed by Sichuan University was industrialized and promoted in Guizhou, Hubei, and Jiangsu, resulting in a production capacity of more than 400,000 tons and a new production value of 2.1 billion yuan. Profit tax 200 million yuan.
This new technology, which ranks the leading domestic level and has independent intellectual property rights, won the National Science and Technology Progress First Prize and the Ministry of Education’s Science and Technology Progress Special Award. It has taken a new approach in combining the traditional ammonium phosphate process and the slurry ammonium phosphate process. , Has become China's current high concentration of phosphate and compound fertilizer industry's leading process route, and the formation of advanced technology can be exported to foreign countries, phosphorus chemical companies at home and abroad have the prospect of promotion.
Sichuan University and Hongfu Co., Ltd. have complemented each other's resources and applied the latest technologies, such as the ammonium sulphate concentrate ammonium phosphate process developed independently, to the large-scale introduction of Guizhou Hongfu Industrial Development Co., Ltd. in only four months. In order to overcome technical difficulties, the first set of powdered ammonium phosphate plant with an annual output of 200,000 tons was built in China, and the combined production of granular ammonium phosphate with the self-developed powdered monoammonium phosphate was realized. The investment was only introduced in the same category. One-third of the devices received good results in reducing energy consumption and increasing output. The completion and production of this device has significant demonstration significance for solving the problems of the existing imported devices, such as insufficient capacity for enriching phosphoric acid and difficulty in achieving production.
