粉状磷酸一铵装置氨化及浓缩工艺的选择

Selectin of Ammoniation and Concentration Process for Powder Monoammonium Phosphate Plant

发展磷铵工业对于促进我国化肥工业和农业的现代化意义重大。介绍了以二水法湿法磷酸为原料,采用“中和料浆浓缩法”生产粉状磷酸一铵的氨化、浓缩工艺,并通过评价试验对生产操作条件进行了分析,为工程设计和控制生产指标提供了理论依据。

The development of ammonium phosphate industry is essential for the modernization of China’s fertilizer industry and agriculture. The ammoniation and concentration process to produce powder monoammonium phosphate employing the neutralization slurry concentration method using dihydrate wet-process phosphoric acid as feed are outlined. Analysis is conducted for the operating conditions through testing,which provides theoretical basis for the engineering design and control of operating figures.
