摘　　要：针对某公司已投产的90万t/a甲醇合成装置Ⅰ运行中出现的合成塔超温、系统结蜡严重、甲醇产品中乙醇含量高等问题,对新建90万t/a甲醇合成装置Ⅱ从工艺流程、设备等方面进行优化。通过改变工艺流程、调整操作指标、增大合成塔换热面积等措施,使合成塔出口温度降低10℃~15℃、合成气消耗降低10 m3/t、产品中副产物明显减少。In view of the problems of over-temperature of synthesis tower,serious wax formation and high ethanol content in the operation of a Phase I 900 kt/a methanol synthesis unit in a company,the process flow and equipment of the newly built 900 kt/a methanol plant in Phase II were optimized.By changing the process flow,adjusting the operation parameters and increasing the heat exchange area of the synthesis tower,the outlet temperature of the synthesis tower was reduced by 10℃-15℃,the syngas consumption was reduced by 10 m3/t,and the by-products decreased significantly.
