摘要
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.
