Abstract

A process for the separation of water from a water-containing mixture of azeotrope, with an extractant which removes water from the mixture or azeotrope, recovery of the non aqueous portion of the mixture or azeotrope as a product, and regeneration of the extractant for reuse by the removal of water therefrom. A feature thereof is that residual water can be removed from the extractant, and the extractant regenerated for reuse by contacting the heated extractant with a portion of the same product from which the water has been removed; or, the extractant can be regenerated in the process by contact with an inert gas which has been dried in the process. The water-containing mixture or azeotrope is preferably contacted with a portion of the vaporous product to recover the heat of condensation for use in the process.
