铜化集团公司磷铵厂原引进罗马尼亚装置的运行情况欠佳。通过降低磷酸浓度 (P2 O5质量分数由40 %～ 44%降至 35% )、选择生产总养分为 57%品位 1 5 42 0的一级品磷铵 (不选择生产总养分 64%品位 1 7470优等品磷铵 ) ,使装置运行情况大大改善 ,对磷矿适应性加强 ,装置满负荷运行 ,消耗降低。磷铵产品质量得到保证。并介绍将原罗马尼亚磷铵标准 1 44 3 0改为生产我国一级品磷铵 1 5 42 0所采取的工艺措施。
The operation of the introduction of the Romanian plant by the Ammonium Phosphate Factory of the Copper Group Company was not good. By reducing the concentration of phosphoric acid (P2 O5 mass fraction from 40% to 44% to 35%), the total production of 57% Grade 1 5 42 0 was selected to produce Ammonium Phosphate (64% Superior product ammonium phosphate), so that the operation of the device greatly improved adaptability to phosphate rock, the device at full capacity operation, reduce consumption. Ammonium phosphate product quality is guaranteed. And introduced the technical measures taken by changing the original Romanian ammonium phosphate standard 1 44 3 0 to producing the first grade ammonium phosphate 15 5 42 0 in our country.
