On May 14, after an operation test, the technological transformation of the annual output of 240,000 tons of ammonium phosphate plant by Jiangxi Liuguo Chemical Co., Ltd. was successful. This technological transformation investment of more than 80 million yuan, is expected to produce more than 20 million yuan in economic benefits.
The ammonium phosphate device adopts the Spanish ERT-ESPINESA single-tubular reactor process and is the only ammonium phosphate device in China currently using this process. The process has high ammonia emission, excessive moisture, and unstable product quality, which not only affects the efficiency of the enterprise, but also affects the market reputation and competitiveness of the Shida Zhuang brand.
Since the beginning of this year, Six Nations Chemicals has stepped up technological innovation and invested more than RMB 700,000 in March this year to carry out technical reforms on the tail gas scrubbing of ammonium phosphate plant, which can create an annual economic benefit of more than RMB 10 million. In May, an ammonium phosphate plant with less than RMB 100,000 investment was used to pelletize the secondary ammonia conversion technology. The technological transformation was performed using a single-tube reactor and an ammoniated pelletizing process for the reaction and granulation sections. Adjust, properly reduce the degree of neutralization of the tubular reactor, improve the single-tube reactor granulation process conditions, to achieve the purpose of saving steam consumption, improve the product roundness of the product, and improve the appearance of the product quality. This technological change saves about 6 tons of steam per hour, and generates an annual profit of more than 10 million yuan.
It is reported that this set of annual production of 240,000 tons of ammonium phosphate plant is China's first large-scale domestic ammonium phosphate plant, completed and put into production in October 1991, passed the national acceptance in June 1994, and received the first prize for scientific and technological progress in the Ministry of Chemical Industry in the same year. In the year won the second prize of national science and technology progress.
