2那精细化工,间歇反应,5L的加氢反应釜,高危工艺加氢反应尾气组成怎么监控??可以直接排放吗?

3那尾气组成大概是什么?不能直接排放,对有要求的需要设置在线分析仪器。

4那加氢还原,会产出氯化氢,肯定不可以直接排放,需要增加盐酸吸收系统,还有为了安全起见,在反应过程中应该有氮气保护,在盐酸吸收系统需要增加氮气气提更安全。经过盐酸吸收后的尾气再经过洗涤塔,就可以直接高空放空了。

5那尾气要在线监测,处理合格后排放

6那我见过的的工艺,如二楼所说的,加氢尾气先经过冷凝器冷凝,回流一部分,一部分不凝气经过吸收,吸收液经汽提回收或者二楼所说的氮气气提,精馏,未吸收的的再经酸洗或者碱洗,水洗,具体看气相的性质了,水洗后排火炬或者达标排空。

7那连续加氢工艺,一般只是开车停车时有氢气排放。反应过程中,只有少许惰性气体排放。可以减少氢气消耗。减少对空气的污染。

8那你这啥具体内容没说,如何对症下药
