非等压醇烷化工艺技术在合成氨厂的应用

摘要

介绍了合成气净化的几种方法并进行了比较,重点介绍了非等压醇烷化工艺在合成氨厂的应用情况.采用非等压醇烷化工艺对氨合成的补充气进行精制,可以制得高纯度合成气,满足氨合成需要,同时副产甲醇.应用结果表明,该工艺能降低消耗,提高企业经济效益,是一种性价比较高的净化气精制工艺,适合用于合成技术改造.%Several processes for synthesis gas purification are presented and compared. The application of non-isobaric methanol-izing-methanation process in ammonia plant is described with emphasis. The refinement of supplemental gas in ammonia synthesis using the non-isobaric methanolizing-methanation technology can obtain high purity synthesis gas for the ammonia synthesis and co-produce methanol. The results of application indicate that the process is a high performance-price ratio technology which can reduce consump-tion, increase enterprise economic benefits and is suitable for ammonia synthesis technical transformation.
