钛白副产硫酸亚铁制取硫酸钾的工艺研究

STUDY ON THE PREPARATION OF K 2SO 4 FROM THE BY-PRODUCT FeSO 4 IN THE PRODUCTION OF TiO 2.

以硫酸法钛白厂副产硫酸亚铁和氯化钾为原料，采用两步复分解法制取硫酸钾，实验研究了加水量、蒸发水量、洗水量等对工艺过程的影响。

The K 2SO 4 is prepared by two-step double decomposition method,the by-product FeSO 4 from TiO 2 production and KCl are as raw materials.The effect of amounts of water adding,water evaparating and washing water on the process are studied.
