利用碱废液与副产高低温盐生产氯化镁、精制盐及硫酸钙

Manufacture of magnesium chloride, refining salt and calcium sulphate from waste alkali liquor and high or low temperature salt by-product

根据氨碱厂排弃的含钙废液及盐化工副产的高低温盐所含各种盐成分的性质不同，将二者定量匹配，通过化学反应、保温沉降、离心分离、蒸发浓缩等，生产出白色氯化镁、精制盐、硫酸钙；并对此工艺的经济性作了分析。

According to the composition and property of the calciferous waste liquor from ammonia-alkali plant and high or low temperature salt by-product from processing salt chemically,the white magnesium chloride,refining salt and calcium sulphate were manufactured by compounding,reacting,insulated setting,centrifugal separating and concentrating.The economic of the process was also analyzed.
