Abstract
One exemplary embodiment can be a process for minimizing a solvent in a raffinate stream of an extractive distillation column. The process can include providing sufficient separation in the extractive distillation column between a reflux stream having an effective amount of water and a stream having an effective amount of solvent. Usually, the reflux stream has no more than about 2,000 ppm, by weight, solvent based on the weight of the reflux stream.
