常压式固定床增氧制气项目改造总结

Summary on Renovation of Atmospheric Pressure Fixed-bed Oxygen-enriched Gasification Project

为充分利用空分装置来的富余高压纯氧,心连心公司对常压间歇式固定床制气工艺进行了增氧制气改造。简述了固定床增氧制气的工艺流程和增氧制气的投运原则,介绍了增氧制气项目的工艺安全联锁及施工过程中的安全控制,对比了增氧制气项目投运前后的生产数据。经过改造,单炉产氨量有所提升,煤耗、电耗均有所降低,气体成分也有不同程度的改善。

In order to make full use of high-pressure pure oxygen from air separation unit,oxygen-enriched gasification renovation for atmospheric intermittent fixed-bed gasification was carried out in Henan Xinlianxin Fertilizer Co.,Ltd.The process and operation principle of fixed-bed oxygen-enriched gasification were briefly described.Besides,safety controlment of oxygen-enriched gasification project in the process safety interlocking and construction were introduced.And the production data before and after the project operation were compared.The results showed that the ammonia production of the single furnace was increased.The coal consumption and power consumption per ton of ammonia were reduced,and the gas composition had also been improved to different extents.
