International audienceThe pervaporation, a membrane separation process, can be an excellent alternative to distillation. Though it is a relatively young technology, the attention of industries towards it increases every year mainly due to its low energy consumption and high separation performance. The aim of our work was to emphasize the new horizons of solvent dehydration technology and mark the contribution of pervaporation in process eco design. We have experimentally and theoretically studied the pervaporation applied to a dehydration of an aqueous mixture of three glycol ethers which are widely used in different chemical industries all over the world. The interest was mainly pointed towards the separation efficiency and energy consumption. The results were compared to those of distillation for the same mixture. The modeling of both processes was also performed in order to optimize operating conditions and increase the efficiency
