NH^+_4对磷石膏转化法制硫酸钾新工艺过程影响的研究

The Study of Influence of NH + 4 of a New Technologic Process on Potassium Sulfate Production by Conversion Method with Sodium Chloride and Phosphogypsum

文章中采用正交实验设计的方法，研究了在磷石膏转化法制硫酸钾第一、二阶段反应过程中的ＮＨ＋４影响变化规律。确定了提高ＮＨ＋４利用率和降低ＮＨ＋４进入产品硫酸钾中的量提高产品质量的途径和方法。

The change law of NH + 4 influence in the first and second stage reaction process of potassium sulfate production by conversion method is studied in this paper.The way to increase utilization ratio of NH + 4 and product quality of K 2SO 4 and reduce NH + 4 content in potassium sulfate is determined.
