"本帖最後由 liaanfeng 于 2 2-11 1: 修正 低温甲醇洗メタノール再生塔頂酸性気管线詰まりの頻度、詰まった後硫回收切り気、パイプをすっきりさせる。非常に面倒です。現象と原因:1、洗氨塔入塔11115PPM、出塔55555PPM.

可以咨询工艺包提供方解决,估计是简化水洗塔的后果,不懂工艺瞎简化害死人啊

你们怎么解决的?或者有什么思路?要学*下

楼主首先你们应该分析洗氨塔前后氨含量进行对比,可以适当洗涤液量,然后在置换一部分甲醇,看看效果怎么样。洗涤液是什么?
Reply #92017-05-23
水,45℃左右的水,进口39ppm 出口6 PPM。置换甲醇了,置换了约1/6,有效果,但是效果持续时间很短,不足一月。

酸性气管线到硫回收没有伴热吗?
Reply #112017-06-09
打开排氨管线,稍留一点开度,一个月左右,达到新的平衡就好了.到时系统的总硫含量也会降下来. 我们已经运行稳定了,总硫也降至3ppm以下.

加个伴热效果会好一点,我们就是加的伴热
