合成氨弛放气膜分离装置的工艺和操作要点

Process and operation points of membrane separation units in periodic off-gases from synthetic ammonia

简要介绍合成氨弛放气通过膜分离装置,回收90%的氢气,用以提高生产负荷,增加合成氨产量。通过合理设计和正确操作,可以延长膜分离器使用寿命,提高经济效益。

The paper briefly introduces summaries briefly describes the purge gas through the membrane separation unit, recycling 90% of hydrogen, in order to increase the production load increase ammonia production. Through rational design and proper operation, it is possible to extend the life of the membrane separator, improving economic efficiency.
