一氧化碳氧化是现今合成氨厂节约能源、增加产量的较先进的工艺。这比低温变换系统和回收弛放气中氢的方法要优越得多,同时工艺投资少、维修操作简便,增产显著,一般能增产3～5%,配合二氧化碳吸收工艺的改进,能增产约8%,并且总投资费用约七个月左右即可收回,由于经济效果显著,此工艺已引起世界各国合成氨厂 Carbon monoxide oxidation is the more advanced process of energy saving and output increase in the ammonia plant nowadays. This is much superior to the low temperature shift system and the method of recovering the hydrogen in the purge gas. At the same time, the process investment is small, the maintenance is easy and the yield is increased obviously. Generally, the yield can be 3-5%. With the improvement of the carbon dioxide absorption process, the yield can be increased by about 8 %, And the total investment costs about seven months to recover, due to the remarkable economic effect, this process has caused the world’s ammonia plant
