What is the automatic reflux of the distillation column that separates methanol and water? What is the basis? This post was last edited by brainandrain on 2009-4-10 16:30 ]
The pre-tower should be full reflux with a reflux ratio of 0.5-0.8, and the reflux ratio of the atmospheric tower should be controlled at 3: About 1
First, calculate the minimum reflux ratio. The actual reflux ratio is generally 1.2-2 times the minimum reflux ratio.
The extraction part of the distillation liquid must be realized by external work, and the remaining liquid part that does not need to be extracted will automatically reflux. Automatic reflux means that the liquid flows back from the upper section to the lower section due to the position difference. This is achieved through proper internal design and does not require external equipment or kinetic energy.
