["储罐都有氮封的吧，为什么芳烃类的储罐没法加氮封呢。"

Reply #32020-11-09

一般芳烃类，如苯类物料储罐储存是需要进行加热的，无法设置氮封，通常的做法是罐顶加集气罩，通过集气罩引管道至罐底外部水槽。使挥发的气如水溶解稀释，避免有毒气体释放至大气中造成污染。

为啥加热就不能加氮封了？

储罐服役时间长了，一直在运行，没法做强度试验，因此设计院不给设计氮封:lol

集气罩也是第一次听说，没见过，先找个例子学*学*，感谢！

这里不光是VOC的问题吧。没有氮封，那储罐出料的时候，难道补的是空气？没有氮封，一般来说还可以设置平衡管，避免VOC气体的无组织排放。集气罩好像不能解决什么问题
