介绍瓮福引进的 30万 t P2 O5/ a磷酸和 2× 4 0万 t/ a重钙生产技术 ,以及对上述技术的消化创新情况。通过技改 ,瓮福引进磷酸装置能力已达到 4 0万 t P2 O5/ a ,重钙装置为适应市场需要 ,已改造成 2× 6 0万 t/ a DAP生产线。并通过 DAP尾气资源化利用 ,在世界上首创 DAP MAP联产工艺 ,降低了生产成本 ,形成了几项自主知识产权 ,使我国磷铵国产化水平大大提高 Introduce the introduction of Wengfu 300,000 t P2 O5 / a phosphoric acid and 2 × 40 million t / a double calcium production technology, as well as digestion and innovation of these technologies. Through technological transformation, Wengfu’s capacity of introducing phosphoric acid plant has reached 400,000 tons of P2 O5 / a. In order to meet the needs of the market, the TSP plant has been transformed into a 2 × 60 million t / a DAP production line. And through the utilization of DAP tail gas resources, the world first DAP MAP co-production process, reducing production costs, the formation of several independent intellectual property rights, so that China’s national level of ammonium phosphate greatly increased
