二次盐水精制工艺的研究

The Research of the Process of Secondary Brine Purification

主要以河南永银化工实业有限公司10万t/a离子膜烧碱二次盐水工艺为例,介绍了二次盐水精制的必要性及主要工艺指标,二次盐水精制中使用的螯合树脂塔的工艺流程、螯合原理、影响螯合树脂的因素及操作过程中应该注意的问题等方面。

The annual production capacity of 100,000 tons of secondary brine process of ionic membrane caustic soda of Henan Yongyin Chemical Industry Company was example, the need for secondary brine purification process criteria, the chelating chelating principle,the influencing factor operation process were introduced. resin process using in the secondary brine purification, the of chelating resin, and the problem paying attention to during
