盐酸深解析中氯化钙法与硫酸萃取法对比

Comparison Between Catalyst(CaCl) Method and Extraction(Sulfuric Acid) Method in HCl Deep Desorption System

本文简要介绍了盐酸深解析系统中氯化钙与硫酸萃取的系统流程,以及利用添加助剂氯化钙或硫酸萃取的方案。对二种方案从工艺流程、设备选型、系统运行、投资成本、能耗、工艺过程控制等方面进行了论证对比。探讨分析了盐酸深解析中氯化钙萃取法比硫酸萃取法更加适合工厂的投资及使用。

The process and proposal for both Catalyst(CaCl2) Method and Extraction Method in HCl deep desorption system are introduced in this paper.The paper compares the two methods in such respect:Technical process,equipment selection,system operation,cost of investment,energy consumption and pro cess controlling.
