我发现有几家火炬管线因为有氨结晶；管道堵塞；最后出现火炬管线压塌或者闪爆。。。。。。请问大侠怎么防范啊。。。。。。

氨结晶一般来自于酸性气的排放，例如氨汽提塔，气化闪蒸汽的排放。酸性气专门设置酸性气火炬，不要与事故火炬或者开工火炬共用。

就是酸性气火炬管线堵塞啊。。。。。。。。

伴热保温，管线气体温度不低于70℃就没这事儿。

你的酸性气管线怎么会有氨呢？是本来排放的时候就有少量的氨气，还是说后来混进去的？从我的经验分析，酸性气发生氨结晶的可能性比较小，氨管线发生结晶的可能性比较大

酸性水气体应该会有少部分的氨排放

恩，是的，一般这个比例在1%左右，流速低的情况下容易结晶

酸性水汽提增加侧线抽氨或者酸性气管线加伴热

实验过吗？是不是说如果定期进行管线加热处理，也不会存在问题？
