硫酸钙在钙液脱硝采卤过程中溶解度的研究

Research on Solubility of Calcium Sulfate in Brine after Calcium Sulfate Denitration

随着卤水脱硝工艺的大规模应用,卤水中的硫酸钙溶解度会发生较大变化。文章通过模拟卤水脱硝过程,测定硫酸钙在卤水中的溶解度,并讨论了其溶解度与卤水中硫酸钠、氯化钙含量以及介稳区的变化规律。

Solubility of calcium sulfate in brine will change with the largescale application of brine denitration. Through the simulation of the process in brine denitration,solubility of calcium sulfate in brine was tested. Then variation rule about the content of sodium sulfate and calcium chloride,the width of metastable zone were discussed.
