摘要
以芒硝、石灰和二氧化碳为原料 ,借助于一种新的中间物质 ,中间物质可再生循环使用。在液相制碱中 ,对工艺条件进行了试验研究 ,找出了适宜的工艺条件 ,提高了芒硝的转化率。
A new technology for preparing soda with Na 2SO 4、CaO and CO 2 by means of a new medium in liquid phase is reported. The medium can be used again with circulation. In the preparation stage the technological condition is experimented and studied and suitable technological condition is created. Thus, the conversion rate of Na 2SO 4 is enhanced.
