Abstract
We have discovered that addition of water to a mixture of oxygenates increases their volatility relative to methanol. A process and apparatus are disclosed for separating methanol from other oxygenates. Water is separated from a stream comprising water, methanol and at least one other oxygenate to provide a water rich stream and a methanol and oxygenate rich stream. The methanol and oxygenate rich stream and water are fed to a column to provide an oxygenate rich stream and a methanol and water extract stream. The methanol and water can then be readily separated from each other.
