铜洗再生气洗涤回收系统改造小结

Preliminary Summary of Retrofit of Scrubbing and Recovery System for Regenerated Gas from Cuprammonia Wash

通过增加 1座洗涤塔和 1台稀氨水水冷器 ,使洗涤塔塔顶再生气的氨含量由 1.5 %下降至 0 .2 %、塔底排出的稀氨水的氨含量由 1.6 %提高至 5 .6 % ,使铜洗再生气回收系统满足了生产要求。

By the addition of a scrubbing column and a water cooler for dilute aqua ammonia, the ammonia content of the regenerated gas from the top of the scrubbing tower drops from 1.5% to 0.2%, and the ammonia content of the dilute aqua ammonia discharged from the bottom of the tower increaese from 1.6% to 5.6%, so that the recovery system for the regenerated gas from cuprammonia wash meets the production requirement.
