摘　　要：从整个系统的角度出发对合成氨装置脱碳单元进行优化,在保持CO_2输出量不变的基础上,提高CO_2进入尿素装置的压力。结果表明,该优化方法节能效果十分明显,改造后可节约尿素蒸汽消耗2.5 t/h,且涉及到的工艺调整较小,在工程上较易实现,可以很好地降低全厂能耗。The CO2 removal unit of an ammonia plant is optimized from the angle of the whole system to increase the CO2 pressure into urea unit while keeping the CO2 output unchanged. The results show that the energy-saving effect is obvious, saving the urea unit 2.5 t/h steam consumption with only small process adjustment and easy implementation.Therefore the systematic optimization can significantly reduce energy consumption.
