ABSTRACT:
A process for recovery of glycerine from saline waters-containing glycerine comprises evaporating the water to precipitate a major amount of any salts present, separating the liquid phase and diluting it with water to low viscosity, electrodialysing the diluted liquid phase to obtain, (1) a concentrate stream which is recycled to the evaporative step, and (2) a diluate stream which is subjected to fractionation distillation to obtain glycerine as an overhead fraction.
