合成氨催化剂活性降低原因分析与处理措施

Reason analysis and treatment measures of synthesis ammonia catalyst activity decreased

分析了氨合成催化剂活性降低的原因,发现催化剂因CO中毒而导致氨合成塔运行异常,提出了催化剂中毒的处理方法和预防措施,为同类装置出现类似问题提供了借鉴。

The paper analyzes reasons of ammonia synthesis catalyst activity decreased, it finds that catalyst CO poisoning which leads to ammonia synthesis tower abnormal operation, it proposes handling method and precautionary measures for catalyst poisoning, which takes example for similar problems.
