Abstract
Process for the dehydration of gases, comprising: absorbing water vapor by means of a hygroscopic liquid consisting essentially of one or more C-Cglycols and an additive capable of forming a minimum type azeotrope with water; distilling the glycol/water/additive mixture to obtain a top product consisting mainly of the water/additive azeotropic mixture and a bottom product consisting mainly of glycol and additive (hygroscopic liquid); recycling the regenerated hygroscopic liquid to the absorption stage.
