摘　　要：通过在乙烯装置工艺包设计阶段对脱甲烷塔回流流程、甲烷化催化剂选型及工艺技术的优化改进,省去了低温转动设备采购,降低了氢气甲烷化反应系统的蒸汽消耗量,降低了操作人员操作难度,降低了装置建设投资和运行能耗,保障了装置长周期稳定运行。Through the optimization and improvement of the reflux process of demethanizer and the selection of methanation catalyst during the process package design of ethylene plant,the purchase of low-temperature rotary equipment is eliminated,the steam consumption of hydrogen methanation reaction system is reduced,and the operation difficulty of operators is lowered,so as to achieve the purposes of reducing the construction investment and operation energy consumption and ensuring the long-term stable operation of the ethylene plant.
