控速结晶技术在氯化钙生产中的应用

Application of Speed-Control Crystallization Technology in the Production of Calcium Chloride

针对利用氨碱法生产废清液再生产氯化钙时容易产生硫酸钙垢的情况,我们采用了控制结晶技术来加以控制,取得满意效果。文中详述了各项控制参数、过程、方法,以供同行参考。

Based on the fact that calcium sulfate scales often appear when waste liquor from ammonia soda process is reused to produce calcium chloride,we apply speed-control crystallization technology to control it with satisfactory effect achieved.Each controlled parameter,process and method is elaborated in detail for your reference.
