精馏塔进料中不含水，但出料中含有5%水，如何判断出哪里漏了？

Reply #22017-11-01

首先，要确认产品是否吸潮，如果样品放置时间较长的话，含水量分析不准确。其次，排除进料里面是否有热敏物质，高温分解。最后，停车试漏冷凝器和再沸器。

这玩意看看温度变化，如果整个他温度变化不大，应该就是塔顶漏了，都5%了，啥也别说，赶快停了打压试下漏就行了

再沸器或者冷却器，停车检查吧

分析误差，其他进料带水。

元素示踪检测，现货在冷凝器循环水和再沸器蒸汽里加入产品不含的元素，哪次在产品里检测到这种元素就可以判断哪里漏了

检查一下若是塔顶产品则检查循环水的COD值，没问题再去判断再沸器是否漏

工厂见过用氯化钠，测钠离子。钠离子有干扰的话可以用其它无害的杂质
