合成氨回收单元出口氨含量超标原因分析及处理措施

REASON ANALYSIS ON AMMONIA CONTENT EXCEEDING THE STANDARDS AT THE OUTLET OF SYNTHETIC AMMONIA RECOVERY UNIT AND TREATMENT MEASURES

分析合成氨回收单元出口氨含量超标的原因,认为再生塔底部温度低是造成氨回收单元出口氨含量升高的主要症结。通过有效解决再生塔底部温度低的问题,达到降低氨回收单元出口氨含量的目的。

The reason that the ammonia content exceeding the standard at the outlet of synthetic ammonia recovery unit was analyzed.It′s reckoned that the low temperature at the bottom of regeneration tower was the main reason.After solving the problem of the low temperature,ammonia content at the outlet of ammonia recovery unit was reduced.
