摘　　要：介绍了脱除合成气中微量CO的常用方法。通过对低温甲醇洗串甲烷化工艺和液氮洗工艺的比较,说明大型合成氨装置采用液氮洗脱除微量CO具有一定的优势。Methods in common use are presented tbr the removal of trace CO from syngas. A comparison is made between low-temperature methanol wash combined with methanation and liquid nitrogen wash processes, and the resuh indicates that the use of liquid nitrogen wash in a large ammonia unit to remove trace CO has a certain supertiority.
