About reflux ratio
Thread Content
What is the appropriate reflux ratio between the methanol distillation pressurized tower and the normal pressure tower? What impact does oversize and undersize have on production? Everyone is welcome to discuss!
The reflux ratio of the pressure tower in our factory ranges from 1.2 to 1.8, and the normal pressure tower also ranges from 1.2 to 1.8. When the reflux flow is insufficient, the amount of steam in the tower increases, and the tower temperature increases and the heavy components move upward, resulting in unqualified refined methanol quality. ； When the reflux flow is too large, energy consumption will increase, and in severe cases, the alcohol content in the atmospheric tower residual liquid may exceed the standard.
