After more than 50 days and nights, the world's first phosphogypsum granulated ammonium sulfate industrialization plant opened up the entire pipeline in Guizhou Yufu Phosphate Fertilizer Plant last week. The ammonium sulfate product was continuously transported to the next plant for further processing and became a new high-end product. product. This marks the success of the phosphogypsum ammonium sulphate project that has received much attention from the industry. The company has made another major breakthrough in the comprehensive utilization of phosphogypsum. Its comprehensive utilization rate of phosphogypsum waste was increased from 12% to 28%, ranking the forefront of the industry.
As of yesterday's press release, this new device has produced more than 400 tons of quality products. Luanfu R&D personnel are collecting and arranging new equipment operation data to provide more scientific design and technical data for the construction of the next set of 250,000 tons/year ammonium sulfate phosphogypsum plant.
The granular ammonium sulfate production process and equipment are rather special. At present, it has not been promoted in China. Most of the manufacturers and research institutes have only made some technical studies and reserves. Although there are individual companies in foreign countries that can produce, the products are not high-end granular but ordinary powder and block production technology. In May 2009, Fuk-Fu learned the theory and experiment of this technology, and the "splenicity" of industrial production, and made partial adjustments and technological adjustments to the existing idle old devices. The conditions for the operation of the process and equipment were complex and demanding, and the test was run. Under very difficult circumstances, it successfully broke the foreign technology blockade and produced qualified products that meet international standards.
In February 2011, the company's first globally designed phosphogypsum granulated ammonium sulfate plant was completed. The new device with an annual capacity of 250,000 tons of granular ammonium sulfate can “eat†more than 600,000 tons of phosphogypsum solid waste annually (including the supply of phosphogypsum raw materials to Taifu Co.), and more than 80,000 tons of carbon dioxide emissions from Tianfu Company. "Three wastes" emissions, economic and social benefits are obvious. Its industrialized production process is the first case in China, opening up a new approach for the comprehensive utilization of phosphogypsum, filling the gap in the global production of granular ammonium sulfate with phosphogypsum, and promoting the technological progress, industrial structure adjustment and sustainable development of China's phosphorus chemical industry. Development is of great significance.
It is understood that the Yongfu Machangping Industrial Park produces about 3.5 million tons of phosphogypsum annually. Previously, although through the technological innovation, Gengfu has developed and produced a series of environmentally friendly building materials such as gypsum block and construction gypsum, and realized the recycling of part of the phosphorous gypsum waste. However, most of the phosphogypsum is still piled up, not only occupying large amounts of land. , Wasting resources, increasing production costs, and there are some hidden dangers, which restricts the development of industrial parks. The commissioning of this industrial device has found the ideal way out for the sulfur and calcium resources in the phosphogypsum waste and the carbon resources in the carbon dioxide exhaust.
