摘　　要：在天然气蒸汽转化制氢单元中,水碳比控制和联锁设计是非常重要的环节。结合以往天然气转化制氢装置工程设计经验,提出水碳比控制及联锁的优化方案,以满足改进后控制方案的安全性和可操作性,进而实现水碳比的平稳控制,确保装置的正常连续生产。Water carbon ratio control and interlock design are the very important elements in hydrogen preparation unit by natural gas steam reforming in synthetic ammonia plant.Combined with the previous engineering design experience,we updated the synthetic ammonia plant in a fertilizer factory,presented the plan to optimizing water carbon ratio control and interlock in order to meet the safety and operability requirement after updating,therefore to achieve the balance control of water carbon ratio,and ensure the normal and continuous operation of the plant.
